Active-Matrix Liquid Crystal Display (AMLCD)

Also known as TFT Display, or Thin Film Transistor Display. An active-matrix liquid-crystal display (AMLCD) is a type of flat panel display, currently the overwhelming choice of notebook computer manufacturers, due to low weight, very good image quality, wide color gamut and response time

The most common type of LCD display contains, besides the polarizing sheets and cells of liquid crystal, a matrix of TFTs to make a TFT-LCD. These devices store the electrical state of each pixel on the display while all the other pixels are being updated. This method provides a much brighter, sharper display than a passive matrix of the same size. An important specification for these displays is their viewing-angle.

Thin-film transistors are usually used for constructing an active matrix so that the two terms are often interchanged, even though a thin film transistor is just one component in an active matrix and some active-matrix designs have used other components such as diodes. Whereas a passive matrix display uses a simple conductive grid to deliver current to the liquid crystals in the target area, an active-matrix display uses a grid of transistors and capacitors with the ability to hold a charge for a limited period of time. Because of the switching action of transistors, only the desired pixel receives a charge, and the pixel acts as a capacitor to hold the charge until the next refresh cycle, improving image quality over a passive matrix.

Analog Monitor

An Analog Monitor is a monitor or display that is capable of accepting continuously varying or analog signals from the video source. This allows the monitor to display an infinite range of different colors or grey shades. The majority of CRT monitors are analog, while all flat panel displays are inherently digital in nature.

Analog-to-Digital Converter (A/D Converter)

Circuit to convert analog signals to digital signals, may be used in display driving or sensing applications.

Anti-Glare Screen

Anti-Glare Screen refers to a clear panel or filter placed over, or a transparent coating applied to the faceplate of computer monitor to help prevent glare from the sun or other bright light sources from appearing on the screen. These coatings or panels use technologies ranging from a simple etched surface to a quarter wavelength refractive coating who achieve their purpose in minimizing glare.


Any technique used to smooth the jagged edges that are created when diagonal lines are drawn on a digitized image.

Aperture Grille

An Aperture Grille refers to a method of CRT construction employing vertical strips of colored phosphor with a thin screen formed of a grid of tiny metal wires. Electron beams emitted from the electron gun pass through this grid of metal wires and lands on the appropriately-colored phosphor strip, exciting phosphors that produce the on-screen image. An aperture grille construction tends to produce brighter, more saturated colors, but is not as good for text or fine detail.

Aspect Ratio

The aspect ratio of an image describes the proportional relationship between its width and its height.

It is commonly expressed as two numbers separated by a colon, as in 16:9. For an x:y aspect ratio, no matter how big or small the image is, if the width is divided into x units of equal length and the height is measured using this same length unit, the height will be measured to be y units. For example, consider a group of images, all with an aspect ratio of 16:9. One image is 16 inches wide and 9 inches high. Another image is 16 centimeters wide and 9 centimeters high. A third is 8 yards wide and 4.5 yards high.

The most common aspect ratios used today in the presentation of films in movie theaters are 1.85:1 and 2.39:1. Two common video graphic aspect ratios are 4:3, the universal video format of the 20th century, and 16:9, universal for high-definition television and European digital television. Other cinema and video aspect ratios exist, but are used infrequently. In still camera photography, the most common aspect ratios are 4:3, 3:2, and more recently being found in consumer cameras 16:9. Other aspect ratios, such as 5:3, 5:4, and 1:1 (square format), are used in displays, cameras and photography as well, particularly in medium format and large format.

Auto Adjust

A special one-touch Auto Adjust button allows users to quickly set the display panel to match their preferences and provides users with excellent front-of-screen performance and minimal set up.


Brightness is the setting of the basic light level intensity in a computer monitor. This is commonly set in conjunction with contrast to improve the quality of the viewable image.

Brightness Enhancing Film (BEF)

Prism film that increases a display's brightness.

Candela (cd)

The candela is the base unit of measurement of luminous intensity. It is defined as the power emitted by a light source in a particular direction per unit solid angle, weighted by the luminous efficiency function (a mapping of the human eye’s sensitivity to the different wavelengths). A single candela approximates the now-obsolete unit of one candlepower, which was originally defined in England by as the light produced by a pure spermaceti candle weighing one sixth of a pound and burning at a rate of 120 grains per hour.

In photometry, luminous intensity is a measure of the wavelength-weighted power emitted by a light source in a particular direction per unit solid angle, based on the luminosity function, a standardized model of the sensitivity of the human eye. The SI unit of luminous intensity is the candela (cd), an SI base unit.

Candela per Square Meter (cd/m2)

The Candela per Square Meter (also known as a Nit) is the base unit used to measure the luminance of a display. The luminance of a display indicates how of how bright the display’s surface will appear to an eye looking at the surface from a particular angle of view. Computer displays used in typical room environments typically exhibit luminance ranging from 50 to 300 cd/m2. For a screen to be viewable under direct sunlight, a luminance of at least 800 cd/m2 is generally required.

Cathode-Ray Tube (CRT)

A cathode ray tube (CRT) is a vacuum tube which is used to create images in the form of light emitted from the fluorescent screen. In its simplest form, it contains a source of electrons called an electron gun aimed at a fluorescent screen, with a means to accelerate and deflect the electron beam which is used to create images in the form of light emitted from the fluorescent screen.

Color Convergence

Refers to how well the three (red, green, and blue) color guns intersect at each pixel. The better the guns converge, the more closely the red, green, and blue colors fall directly on top of each other, creating a sharper image.

Color Temperature

Defines the whiteness of the white on the screen. Variations are measured in degrees Kelvin. Natural colors used in life-like images, such as people or landscapes, look more true to life when displayed at a color temperature of 6500K. Black text on a white page is better represented by a color temperature of 9300K.

Composite Video (CVBS)

Combines brightness information (Luma), color information (Chroma) and synchronizing signals on one cable; the audio signal is transferred separately. The connector is typically an RCA jack. CVBS stands for Composite Video Blanking and Sync; or Color, Video, Blanking and Sync; or Composite Video Baseband Signal.

Computer Display Standard (VESA)

Table goes here.


Contrast is the term used to describe the degree of brightness variation (white through black) in an image.

Contrast Ratio

The contrast ratio is a measurement of a display’s contrast capability, and is defined as the ratio of the luminance of the brightest color (white) to that of the darkest color (black) that the system is capable of producing. A high contrast ratio is desired in any display. Unfortunately, due to the various methods of measurement employed, as well as variations in operation and unstated variables, the contrast ratio ratings provided by different manufacturers of display devices are not necessarily comparable to each other, and remarkably different measured values can sometimes produce similar results.

Manufacturers traditionally favor measurement methods that isolate the device from the system environment, since that is a factor not under their control. Consequently their measurement methods simulate an ideal room where the only light seen in the room would come from the display device. With such an ideal room, the contrast ratio of the image would be the same as the device.

Real rooms, however, reflect some of the light back to the displayed image, lowering the contrast ratio seen in the image, so display users must generally take the brightness characteristics of the surroundings into account when designing their systems.

Complicating factors somewhat, the ratio of the luminosity of the brightest and the darkest color the monitor is capable of producing simultaneously at any instant of time is called static contrast ratio, while the ratio of the luminosity of the brightest and the darkest color the display is capable of producing over time is called dynamic contrast ratio.


The Display Data Channel, or DDC, is a collection of protocols for digital communication between a computer display and a graphics adapter that enable the display to communicate its supported display modes to the adapter and that enable the computer host to adjust monitor parameters, such as brightness and contrast.

DDC2B Plug & Play

DDC2B/Ab/B+/Bi protocols are a physical link between a monitor and a video card, which was originally carried on either two or three pins in a 15-pin analog VGA connector.

Dead Pixel

A ‘Dead Pixel’ is the term used to describe a pixel that no longer illuminates. The term is more common on LCD and Plasma display technology, whereas a similar defect on a CRT monitor is simply called a ‘Phosphor Defect’.


Degaussing is the method of erasing magnetic charge from a magnetized material. Occasionally, the shadow mask of a color CRT will pick up a magnetic charge, and deform, causing ‘purity’ or discolorations in the video image. The degauss process is achieved by generating a powerful time-varying magnet field that passes through the shadow-mask material and rearranges the magnetic particles in a random order.

Digital Monitor

A Digital Monitor uses a digital video signal rather than an analog video signal to create an image. Unlike an analog monitor, a digital monitor cannot display an infinite range of colors.

Display (Monitor)

Display is the term used to describe the electronic device used to present images and/or text.


DisplayPort is a digital display interface standard put forth by the Video Electronics Standards Association (VESA) since 2006. It defines a new royalty-free, digital audio/video interconnect, intended to be used primarily between a computer and its display monitor, or a computer and a home-theater system.

Dot Pitch

Dot Pitch is the distance between pixels on a computer display screen. It is generally measured in millimeters.

Dots Per Inch – DPI

DPI (Dots Per Inch) is a measurement of display device’s resolution capability, and indicates how many pixels, or dots, the display device can place in one square inch. The higher the DPI, the sharper the image.

3M product that increases brightness by as much as 60% by angle, reflection, and polarization light recycling.

DVI Connectivity

Digital Visual Interface (DVI) is a video interface standard designed to provide very high visual quality on digital display devices such as flat panel LCD computer displays and digital projectors. It was developed by an industry consortium, the Digital Display Working Group (DDWG) to replace the "legacy analog technology" VGA connector standard. It is designed for carrying uncompressed digital video data to a display. It is partially compatible with the High-Definition Multimedia Interface (HDMI) standard in digital mode (DVI-D), and VGA in analog mode (DVI-A).

DVI Standards (DVI-D)

DVI-D stands for "DVI-Digital" and supports digital transfers only.

DVI Standards (DVI-I)

DVI-I stands for “DVI-Integrated” and supports both digital and analog signals; therefore, a user may connect a PC with a VGA port to a display with DVI-I using a special VGA > DVI-I cable. DVI-D: Stands for “DVI-Digital” which supports digital signals only.

EGA - Enhanced Graphics Adapter

Manufactured by IBM in 1984, the Enhanced Graphics Adaptor (EGA) is a digital video standard that falls between CGA and VGA in terms of color and space resolution. Operating with RGB digital TTL video input signal, EGA offered more color selections (16 distinct colors from a palette of 64) than the earlier CGA standards at video resolutions of up to 640×350 pixels.

Energy Star®

A program established by the Environmental Protection Agency (EPA) to become an international standard for energy efficient consumer products. It was formally launched on June 17, 1993. Devices carrying the Energy Star logo, such as computer products and peripherals, kitchen appliances, buildings and other products, generally use 20%–30% less energy than required by federal standards.

Fixed-frequency monitor

Common in older display monitor systems, fixed-frequency monitors are designed to only run at a specific signal from within a limited frequency range.

Flat screen Monitor

A Flat screen Monitor generally refers to a CRT monitor whose faceplate is flat, not curved.

Flat-Panel display (monitor)

Flat panel displays (flat panel monitors) is the term generally used to describe a display device that is not based upon the cathode-ray tube technology. They usually use Liquid-crystal display (LCD) technology, although Plasma and other technologies fit the description as well.


Flicker describes a flashing, or rapid blinking in an image on a display screen. Flicker generally occurs when the video refresh rate of the display system is too low, but it can also be caused by other video-related problems and in some cases by monitor hardware problems. A flickering screen may cause users to experience eye strain. To avoid flickering, the refresh rate should be at least 72 Hz.

Foot candle

A foot candle is the measurement of amount of light reflected by a surface one foot from a lighted candle. The term is becoming obsolete, and is replaced by SI units of cd/m2 or nits.


In the display business, a frame is a single image displayed by the monitor.

Frame rate

The Frame rate, usually measured in Frames Per Second (fps), is frequency at which individual image frames are displayed or projected. Full speed video images generally require a frame rate of 24, 25 and 30 frames per second for optimum performance.

FSTN (Film Compensated SuperTwist Nematic)

A passive matrix LCD technology that uses a thin film optical filter layer between the STN display and front polarizer to change the default colors from blue on yellow-green to black on silver-gray. This is a common technology for many character and graphic panels with resolutions of 320x240 or less. FSTN used in dual-scan mode was used extensively in early laptops.

Full-motion video (FMV)

Abbreviated as FMV, Full-Motion Video is the term used to describe video display systems that are capable of displaying full speed video images and sound on a monitor. Depending upon the video format being used, the frames per second can vary, but computers and displays not capable of displaying at least 24fps will create choppy video.


High-bandwidth Digital Content Protection (HDCP) is a form of digital copy protection to prevent copying of digital audio and video content as it travels across DisplayPort, Digital Visual Interface (DVI), High-Definition Multimedia Interface (HDMI).


HDMI (High-Definition Multimedia Interface) is a compact audio/video interface for transmitting uncompressed digital data. HDMI supports, on a single cable, any uncompressed TV or PC video format, including standard, enhanced, and high-definition video; up to 8 channels of compressed or uncompressed digital audio; and a Consumer Electronics Control (CEC) connection. Because HDMI is electrically compatible with the signals used by Digital Visual Interface (DVI), no signal conversion is necessary, nor is there a loss of video quality when a DVI-to-HDMI adapter is used.


Hercules refers to a monochrome graphics standard introduced in the early 1980s and developed by Hercules Computer Technology for IBM compatible computers. The standard defined a resolution of 720 Pixels by 348 pixels on a monochrome monitor.


Short for Hercules Graphic adapter.

Horizontal Scan Rate

Horizontal scan rate: Horizontal scan rate refers to the speed that each line is drawn horizontally on a display monitor. This is commonly expressed in Kilohertz [KHz].

Image Burn

When a CRT computer monitor is left for long periods of time with a constant image, the image can seep into screen phosphor, leaving a permanent image. Image Burn occurs more often with older monitors, but it can still occur on new CRT monitors if brightness is set too high. To help prevent this effect, turn off the monitor when not in use, or use a screen saver.

Intensity bit

The intensity bit is a fourth bit of information added to the Red, Green, and Blue bits on early digital CGA monitor that is used to display different intensities of color. For example, the RGBI monitor is capable of displaying 16 different colors because of this bit.


Interlacing refers to one of the two methods commonly used to generate a video image on an electronic display screen (the other being progressive scan). The interlace technique was devised for displaying high-quality full-motion-video images on early CRT televisions at while using minimal bandwidth. Interlacing technique uses two fields to create a frame; one field contains all the odd lines in the image, the other contains all the even lines of the image. The two sets of fields are interleaved to create a full frame every second scan. For a given bandwidth and refresh rate, interlaced video will provide a higher spatial resolution than progressive scan.


Red Green Blue Intensity (RGBI) is the technology used to generate a 16-color image on early digital-input computer monitors. 16-colors are created by the addition of an intensity bit to the digital signals controlling the three primary colors, red, blue, and green. The 16 colors created are black, dark gray, light gray blue, light blue, green, light green, cyan, light cyan, red, light red, purple, light purple, yellow, light yellow and white.


A Nit is another term for one candela per square meter (cd/m2), which is the SI (International System of Units) base unit for measuring luminance. In the display monitor industry, it is used to measure the brightness of the surface area of a CRT monitor, LCD or other display device. A nit is equal to one candela per square meter. The term, Nit, comes from the Latin niter, to shine.xx Computer displays typically have luminance of 50 to 300 cd/m2. A luminance of at least 800 cd/m2 is required for a screen to be viewable under direct sunlight.


Short for National Television System Committee, NTSC is the American committee responsible for creating technological television and video standards, including refresh rate and color capabilities. NTSC Composite Video is the standard for analog color televisions.


An on-screen display (abbreviated OSD) is an image superimposed on a screen picture, commonly used by modern Televisions, VCRs, DVD Players and Monitors to display information such as volume, channel, and time and to adjust the unit settings.


Short for Phase Alternating Line, PAL is the dominant television standard used across Europe. Pal delivers 625 lines of resolution, interlaced at 50 half-frames per second (25 Frames per second).


Display persistence is amount of time it takes for the phosphor in a CRT display to lose all of its charge. The longer the persistence, the less flicker there is. However, long-persistence phosphors exhibit ‘ghosting’ with moving images.


Short for Professional Graphics Adapter.PGA was an early video standard developed by IBM that supports up to 640x400 resolution.

Pivot Adjustment

Pivot enables the monitor screen to be rotated 90 degrees into a vertical position (also called portrait mode). This eliminates the need to continually scroll up and down on vertically oriented programs. It is ideal for viewing email, PDFs, documents and spreadsheets.


A contraction of the words "picture element," these are the basic dots on the display screen that make up the image you see.

PPI - Pixels Per Inch (See Dots-per-Inch)

Short for Pixels Per Inch, PPI is the numbers of pixels per inch that comprises a pixel image. Also called ‘dots per inch’, PPI is a measurement of display device’s resolution capability. The more pixels per inch the image contains, the sharper the image will be.

Refresh Rate

Measures the speed that the entire screen is rescanned. Higher frequencies reduce flicker, because they light the pixels more frequently, reducing the dimming that causes flicker; also called vertical frequency. Resolution: The number of distinct pixels in each dimension that can be displayed. In common usage, this refers to the number of pixels displayed on screen horizontally and vertically. A resolution of 1680 x 1050 means you can see 1680 pixels horizontally and 1050 vertically. Higher resolution means that you can see more of your image on the screen without scrolling or panning.

Response Time

The amount of time a pixel in an LCD monitor takes to go from black to white and back to black again. It is measured in milliseconds (ms). Typically, lower numbers mean faster transitions and therefore fewer visible image artifacts.

RGB monitor (Color Monitor)

RGB Monitors are computer monitors that use three distinct video signals (red, green, blue) to generate the colors displayed on the monitor screen.


Red Green Blue Intensity (RGBI) is the technology used to generate a 16-color image on early digital-input computer monitors. 16-colors are created by the addition of an intensity bit to the digital signals controlling the three primary colors, red, blue, and green. The 16 colors created are black, dark gray, light gray blue, light blue, green, light green, cyan, light cyan, red, light red, purple, light purple, yellow, light yellow and white.


RS-170 was the original black-and-white television signal standard defined by the EIA (Electronics Industries Association). The RS-170 video standard specifies the timing and signal characteristic of broadcast video in the United States, Japan, and several other markets. It specifies a composite signal with well-defined voltage, sync levels and blanking timings, at a horizontal refresh rate of 15.75-KHz and a 60-Hz vertical interlaced scan frequency.

RS-170 delivers 625 lines of resolution, with the odd and even lines interlaced at 60 half-frames per second (30 Frames per second). The 60-Hz field rate was chosen to give adequate full-motion-video capability while avoiding interference from ac current fields.

RS-170 RGB

RS-170 RGB refers to RGB signals timed to RS-170 specifications. In RS-170 RGB, the red, green and blue signals are actually three individual monochrome signals representing their respective red, green, and blue colors which conform to the RS-170 video format, and which share one composite sync signal which is (usually) combined with the green signal. Although video intensity information and blank timing intervals are present in the red and blue signals, the composite synchronization pulses typically are not.

Alternatively, a fourth signal containing only the composite synchronization information may be used to drive an external synchronization input of an RGB display.

Some computer graphic displays and some cameras require separate horizontal and vertical drive inputs as well and may require Transistor/Transistor Logic (TTL) voltage pulses (3-5 V).

RS-170A (NTSC Color Video)

Twenty years after the drafting of RS-170, the EIA video signal standards committee proposed the RS-170A color video standard, which evolved into what is known today as the NTSC composite video signal standard. In this standard, color images are produced on a video display by mixing different intensities of red, green, and blue light which have been encoded onto 1, 2, 3, or 4 wires.

The earliest version of the RS-170A standard was the single-wire composite video format known as the basic NTSC video standard. Based the original RS-170 monochrome video standard, the NTSC color video signal contains intensity, color, and timing information on the same line. The basic intensity and timing information conforms to the RS-170 monochrome standard, while the color information is superimposed on the intensity waveform. Information contained in a ‘color burst’ located in the back porch of each horizontal scan signal is used to decode the color information. This color information is combined with the analog intensity signal to reconstruct the three primary colors needed to generate a colorized image. The encoding scheme was designed such that, with the proper filtering, a RS-170 monochrome monitor will produce an acceptable black and white image when fed an NTSC color video signal.

The two-wire version of the RS-170A color standard is known as "S-Video". In this format, one pair of coax wires carries the Y channel, which contains the combined intensity and timing signals in accordance with the RS-170 monochrome standard. A second wire pair, the ‘chroma’ or C channel, carries a separate color signal which transmits the color information. S-video is usually transmitted over a single cable with a special 4-pin connector on either end.

The four-wire format is known as RGBS for Red, Green, Blue, and Sync. RGBS video is a "component video" format, meaning the various components of information required to reproduce a video display are enclosed by the three separate video signals as well as a separate composite sync signal. In this case the color signal is broken into three separate and equal channels, each carrying high-resolution information. Timing information is provided on a separate wire - the synch channel. Timing information is sometimes also present on the green channel, but more often not. This video format is called RS-170 RGB.

RS-343 specifies a 60 Hz non-interlaced scan with a composite sync signal with a variety of timings that produce a non-interlace (progressive) scan at resolutions ranging from 675 to 1023 lines.

This standard is used by high resolution video cameras used in applications such as: infrared targeting, low-light, night-vision cameras, and other special military display systems.


RS-343 is an EIA (Electronics Industries Association) standard for non-broadcast high resolution monochrome video. RS-343 was introduced later than RS-170 and intended as a signal standard for High-definition Closed-Circuit Television. Among other things, it reduced the total composite video signal amplitude to 1.00 Vp-p.

According RS-343, the signal specifications are:

  • White: +0.714V
  • Black: +0.054V
  • Blank: (0V reference)
  • Sync: -0.286V
Screen flicker

Screen flicker describes a flashing, or unsteadiness in an image on a display screen. Flicker most often occurs when the video refresh rate is too low, but it can be due to other video related issues and, in some cases, hardware problems with the monitor. Screen Flicker may cause users to experience eye strain. To avoid flickering, the refresh rate should be at least 72 Hz.

Shadow mask

On standard color CRT monitors, the shadow mask is a perforated metal screen located behind the faceplate of a color CRT to ensure the three colored beams hit the appropriately-colored phosphor dot. All early color televisions and the majority of CRT computer monitors, past and present, use shadow mask technology.

SuperTwisted Nematic

Abbreviated as STN, SuperTwisted Nematic is a type of liquid-crystal-display (LCD) used in portable computers and flat panel displays. STN builds on the twisted nematic (TN) construction method, which twists liquid molecules, causing the LCD display to have a sharper contrast and better viewing angle.

SVGA (Super Video Graphics Array)

Short for Super Video Graphics Array, SVGA is a set of video standards introduced by IBM in 1987 as an extension of the VGA standard. In 1989, Super VGA was adopted and defined by the Video Electronics Standards Association (VESA), an open consortium set up to promote interoperability and define standards.

In the first version, SVGA defined a resolution of 800 × 600 pixels where each pixel could be any of 16 colors selected from a color palette. The SVGA standard was soon expanded to 1024 × 768 8-bit pixels and beyond in the following years.

When used as a resolution specification, the term SVGA mow most commonly refers to the original resolution of 800 × 600 pixels.

Swivel Adjustment

The ability for the monitor screen to be rotated left or right. This enables users to share screen images without causing visual distortion.

Tilt Adjustment

The ability for the monitor screen to move up and down. Tilt adjustment enables a user to change the viewing position of the display, creating a more comfortable view of the screen. Users whom view a monitor through the lower portion of bifocal, trifocal or progressive addition lenses may find tilt settings extremely helpful.

TTL Input

Transistor–transistor logic (TTL) is a class of digital circuits built from bipolar junction transistors (BJT) and resistors. It is called transistor–transistor logic because both the logic gating function (e.g., AND) and the amplifying function are performed by transistors. These signals have only two states: Low and Hi.

USB Connectivity

Universal Serial Bus (USB) offers a single connector.


Short for Visual Display Unit, or Video Display Unit, VDU is a term used to describe a device a computer uses to display visual information. Although flat panel displays, monitors and projectors are all examples of a VDU, the term is most commonly used to describe a standard CRT monitor.


Video Electronic Standards Association. A group made up from the video electronics industry to review proposals and develop standards to promote uniformity and economies of scale in the video electronics industry.

VESA - Video Electronics Standard Association

Short for Video Electronics Standard Association, VESA is an international standards organization founded in the late 1980s by a group of monitor and video card manufacturers to define various display standards for computer graphics systems.

VGA Connector

A VGA connector is a three-row 15-pin DE-15 connector. The 15-pin VGA connector is found on many video cards, computer monitors, and some high definition television sets. VGA connectors and cables carry analog component RGBHV (red, green, blue, horizontal sync, vertical sync) video signals, and data.

Viewing Angles

The horizontal or vertical angle at which the user can view the screen image with no loss of color fidelity or image clarity.

Viewing Angles

White Light Emitting Diode (WLED) is a backlight technology which provides the ‘light source’ for the display. ‘LED’ backlighting technology is quickly replacing ‘CCFL’ (Cold Cathode Florescent Lamp) backlight technology as the backlighting source for LCD monitors. WLED panels consume less power than CCFLs and because they are solid state components, they are more resistant to damage caused by external shock. Most importantly, WLEDs eliminate the use of mercury, which addresses the growing concern of these substances and furthers ecological conservation efforts.


Short for Wide SXGA, WSXGA is a resolution that supports 1600 by 900 pixels or 1600 x 1024 pixels.

WUXGA (Wide Ultra Extended Graphics Array)

Short for ‘Wide Ultra Extended Graphics Array’, WUXGA has a resolution of 1920 by 1200 pixels.


Short for Wide XGA, WXGA is a video resolution that supports a maximum resolution of 1366 by 768 pixels.


A color space used in video electronics, for component video cables. YPbPr is the analog version of the YCbCr color space; the two are numerically equivalent, but YPbPr is designed for use in analog systems, and YCbCr is intended for digital video.
