tft lcd displays matrix lcds pricelist

The EA 9707-V24S interface allows dot-matrix LCDs to be programmed easily and quickly. The interface can be soldered directly onto almost all dot-matrix modules. It is connected to a standard RS-232C interface.

This is another story just like those, except this one involves the very screen you’re probably looking at, especially if it’s based on LCD technology.

In the 1970s, a pair of engineers that worked for Westinghouse, T. Peter Brody and Fang-Chen Luo, came to develop the first active-matrix LCD screen. Brody, born in Hungary, had gained an interest in the fledgling technology of thin film transistors, an experimental technology that had come to be seen as a potential avenue for visually displaying content in a more compact form than a cathode-ray tube.

“It has been apparent for some time that a solid-state flat panel display is conceptually achievable,” the patent filing stated. “Efforts to utilize silicon technology to this end are limited by the size limitation problems of the silicon wafer, which negates achievement of large area displays.”

But it was the starting point of the technology that stuck. By the mid-1990s, active-matrix displays that relied on color became the norm in laptops, thanks to their combination of vivid color and thinness. But despite the concept coming from an American company’s R&D department and improved by other American R&D departments, nearly all panels were developed by Japanese manufacturers even at the beginning of their mainstream use cases.

In fact, Westinghouse’s efforts with the flat-panel LCD display ended way back in the 1970s, as did similar efforts at other large U.S. companies. “Both large corporations and venture capital-backed start-ups have quit the field, usually after hitting production difficulties,” authors Richard Florida and David Browdy wrote.

TFT stands for "thin-film transistor" and it is a type of technology used by LCD (liquid crystal display) screens. Older LCD screens used a type of display called "passive" and they were plagued with ghosting and slow refresh rates. "Active" technology using thin-film transistors makes for brighter and faster screens, so all current color LCD displays use TFT technology.

Plasma is another display technology that competes with LCD. Plasma technology works by exciting pixels with a plasma discharge between two glass plates. It is fairly exotic technology and it can produce exceptionally pleasing pictures. That"s why plasma screens are generally more expensive than LCD.

When choosing between plasma and LCD TVs, you"re actually selecting between two competing technologies, both of which achieve similar features (i.e., ,bright crystal-clear images, super color-filled pictures) and come in similar packages (i.e., 3.5 inch depth flat screen casing). To complicate the decision-making process further, price and size are two previous considerations that are rapidly becoming non-issues as LCD TVs are now being made in larger sizes and at competing prices with plasma.

Whether spread across a flat-panel screen or placed in the heart of a projector, all LCD displays come from the same technological background. A matrix of thin-film transistors (TFTs) supplies voltage to liquid-crystal-filled cells sandwiched between two sheets of glass. When hit with an electrical charge, the crystals untwist to an exact degree to filter white light generated by a lamp behind the screen (for flat-panel TVs) or one projecting through a small LCD chip (for projection TVs). LCD TVs reproduce colors through a process of subtraction: They block out particular color wavelengths from the spectrum of white light until they"re left with just the right color. And, it"s the intensity of light permitted to pass through this liquid-crystal matrix that enables LCD televisions to display images chock-full of colors-or gradations of them.

TFT Glass has as many TFTs as the number of pixels displayed, while a Color Filter Glass has color filter which generates color. Liquid crystals move according to the difference in voltage between the Color Filter Glass and the TFT Glass. The amount of light supplied by Back Light is determined by the amount of movement of the liquid crystals in such a way as to generate color.

The most common liquid-crystal displays (LCDs) in use today rely on picture elements, or pixels, formed by liquid-crystal (LC) cells that change the polarization direction of light passing through them in response to an electrical voltage.

The segment drive method is used for simple displays, such as those in calculators, while the dot-matrix drive method is used for high-resolution displays, such as those in portable computers and TFT monitors.

Two types of drive method are used for matrix displays. In the static, or direct, drive method, each pixel is individually wired to a driver. This is a simple driving method, but, as the number of pixels is increased, the wiring becomes very complex. An alternative method is the multiplex drive method, in which the pixels are arranged and wired in a matrix format.

To drive the pixels of a dot-matrix LCD, a voltage can be applied at the intersections of specific vertical signal electrodes and specific horizontal scanning electrodes. This method involves driving several pixels at the same time by time-division in a pulse drive. Therefore, it is also called a multiplex, or dynamic, drive method.

In passive-matrix LCDs (PMLCDs) there are no switching devices, and each pixel is addressed for more than one frame time. The effective voltage applied to the LC must average the signal voltage pulses over several frame times, which results in a slow response time of greater than 150 msec and a reduction of the maximum contrast ratio. The addressing of a PMLCD also produces a kind of crosstalk that produces blurred images because non-selected pixels are driven through a secondary signal-voltage path. In active-matrix LCDs (AMLCDs), on the other hand, a switching device and a storage capacitor are integrated at the each cross point of the electrodes.

The active addressing removes the multiplexing limitations by incorporating an active switching element. In contrast to passive-matrix LCDs, AMLCDs have no inherent limitation in the number of scan lines, and they present fewer cross-talk issues. There are many kinds of AMLCD. For their integrated switching devices most use transistors made of deposited thin films, which are therefore called thin-film transistors (TFTs).

An alternative TFT technology, polycrystalline silicon - or polysilicon or p-Si-is costly to produce and especially difficult to fabricate when manufacturing large-area displays.

Nearly all TFT LCDs are made from a-Si because of the technology"s economy and maturity, but the electron mobility of a p-Si TFT is one or two orders of magnitude greater than that of an a-Si TFT.

This makes the p-Si TFT a good candidate for an TFT array containing integrated drivers, which is likely to be an attractive choice for small, high definition displays such as view finders and projection displays.

The TFT-array substrate contains the TFTs, storage capacitors, pixel electrodes, and interconnect wiring. The color filter contains the black matrix and resin film containing three primary-color - red, green, and blue - dyes or pigments. The two glass substrates are assembled with a sealant, the gap between them is maintained by spacers, and LC material is injected into the gap between the substrates. Two sheets of polarizer film are attached to the outer faces of the sandwich formed by the glass substrates. A set of bonding pads are fabricated on each end of the gate and data-signal bus-lines to attach LCD Driver IC (LDI) chips

To reduce the footprint of the LCD module, the drive circuit unit can be placed on the backside of the LCD module by using bent Tape Carrier Packages (TCPs) and a tapered light-guide panel (LGP).

The performance of the TFT LCD is related to the design parameters of the unit pixel, i.e., the channel width W and the channel length L of the TFT, the overlap between TFT electrodes, the sizes of the storage capacitor and pixel electrode, and the space between these elements.

The design parameters associated with the black matrix, the bus-lines, and the routing of the bus lines also set very important performance limits on the LCD.

In a TFT LCD"s unit pixel, the liquid crystal layer on the ITO pixel electrode forms a capacitor whose counter electrode is the common electrode on the color-filter substrate.

Applying a positive pulse of about 20V peak-to-peak to a gate electrode through a gate bus-line turns the TFT on. Clc and Cs are charged and the voltage level on the pixel electrode rises to the signal voltage level (+8 V) applied to the data bus-line.

The voltage on the pixel electrode is subjected to a level shift of DV resulting from a parasitic capacitance between the gate and drain electrodes when the gate voltage turns from the ON to OFF state. After the level shift, this charged state can be maintained as the gate voltage goes to -5 V, at which time the TFT turns off. The main function of the Cs is to maintain the voltage on the pixel electrode until the next signal voltage is applied.

In an active-matrix panel, the gate and source electrodes are used on a shared basis, but each unit pixel is individually addressable by selecting the appropriate two contact pads at the ends of the rows and columns.

By scanning the gate bus-lines sequentially, and by applying signal voltages to all source bus-lines in a specified sequence, we can address all pixels. One result of all this is that the addressing of an AMLCD is done line by line.

Virtually all AMLCDs are designed to produce gray levels - intermediate brightness levels between the brightest white and the darkest black a unit pixel can generate. There can be either a discrete numbers of levels - such as 8, 16, 64, or 256 - or a continuous gradation of levels, depending on the LDI.

The color filter of a TFT LCD TV consists of three primary colors - red (R), green (G), and blue (B) - which are included on the color-filter substrate.

A TFT display is a form of Liquid Crystal Display with thin film transistors for controlling the image formation. The TFT technology works by controlling brightness in red, green and blue sub-pixels through transistors for each pixel on the screen.

Compare IPS vs TFT displays - the TFT display is the display of choice for industrial designs, but it can have its limitations. A newer technology called IPS (in plane switching) offers better viewing angles and colours, but is it really the best choice - we discuss benefits and negatives of both types of TFT display.

A layer of glass with a matrix of conuctive elements behind that when pressed with another conductive input (ie human finger) registers a touchpoint..

A liquid crystal display structure in which switching transistors or diodes are attached to each pixel to control the on/off voltage. It produces a brighter and sharper display with a broader viewing angle than a passive matrix display. Also known as AMLCD (active matrix liquid crystal display). See TFT (thin film transistor).

A type of flat panel display in which each pixel has it"s own transistor `switch" rather than being activated by it"s address within a matrix of rows and columns. This direct switching radically improves response times enabling full-motion video to be shown without blurring.

The most common type of LCD (Liquid Crystal Display) used in the majority of laptops and most LCD panels and projectors. A typical active matrix TFT display is a single panel of LCD glass that modulates all three primary colors. Most of these offer contrast ratios up to 100:1 for good color dynamics, and just enough speed to handle video and 30fps multimedia with little or barely distinguishable hesitation (jerkiness).

LCD monitors with an analog interface can accept an analog video signal using standard RGB connectors for personal computers, in the same way as a CRT monitor. The analog signal is then converted into the digital signal used for display on a LCD panel. LCD monitors with only a digital interface require a dedicated graphics adapter and connectors, which come in varied formats.

A treated glass panel that is placed over a monitor screen to reduce glare from light sources. Non-glare CRTs often use a coating baked onto the screen at the time of manufacture, which provides a significant reduction in glare; however, LCD screens may completely eliminate it.

The light source for a transmissive LCD. Basically, two techniques are used in transmissive LCD designs, direct lighting and side lighting. Direct-lit backlights use CCFTs (cold cathode fluorescent tubes) and a diffuser panel directly in back of the LC (liquid crystal) layer. Side-lit backlights use CCFTs and a light pipe on one or more of the edges of the display.

A technique used to make flat-panel displays easier to read in low ambient light conditions. The most commonly used types of backlighting are LED, EL (electro luminescent) or CCFL (Cold Cathode Fluorescent).

A metal or plastic frame which fits over the LCD glass to protect the edges of the glass. The bezel acts as a pressure device, compressing the elastomer connector between the LCD glass and PCB.

A technique where the alignment layer on the LCD substrate is rubbed in one or more directions. This process aligns the liquid crystal molecules parallel to the buffing direction. See alignment layer.

These are the fluorescent tubes that provide the light for the LCD unit. These tubes are generally very thin, approximately 2 mm in diameter. See fluorescent lamp.

The LCD driver is formatted into an area on the PCB. Electrical connections are made by micro diameter gold wires. The entire area is then covered with epoxy.

In LCD graphic modules, a type of fluorescent backlighting or edge lighting. One or more fluorescent lamps behind the LCD panel that provides the light that is either blocked (black) or passed (white) by the LCD cell. Used in medium to large size graphic LCD modules.

Color matching refers to the process of accurate duplication of colors between the display and either input (like a VGA card) or output (like a printer). An LCD display with color matching stores color-related parameters in special memory called EEPROM, and uses this data for optimization, providing benefits such as WYSIWYG printing and faithful representation of Web graphics.

The difference in luminance between a white square centered on the screen and the black surrounding area. A method of measuring the dynamic range. A contrast ratio of 15:1 (passive matrix LCDs), offers washed out colors, little detail and image that can barely survive with significant ambient light. Projectors with active matrix TFTs have ratios to 100:1, DLPs from 125:1 and Poly-Si Liquid Crystal Displays 200:2.By comparison, transparency film (i.e. 35mm slides) have contrast ratios over 500:1.

CSTN is an abbreviation of Color Super-Twist Nematic, a Liquid Crystal Display technology to produce full-color.Unlike TFT, CSTN is based on a passive matrix, which is less expensive to produce.The original CSTN displays developed in the early 1990"s suffered from slow response times and ghosting. Recent advances in the technology, however, have made CSTN a viable alternative to active matrix displays.New CSTN displays offer 100ms response times, a 140 degree viewing angle and high quality color rivaling TFT displays.A newer passive-matrix technology called High Performance Addressing (HPA) offers even better response times and contrast than CSTN.

A row or block of dots, used to indicate the location of the next character or symbol to be entered. Used in dot matrix character and graphic LCD modules.

TFT LCD panels support either 6-bit or 8-bit RGB color output, allowing them to display 262K or 16.7M distinct colors, respectively. Using so-called dithering techniques, an analog-to-digital signal processor can simulate 8-bit RGB color output on an LCD panel that actually supports only 6-bit color.

The smallest active element that forms all text and graphics on the LCD screen. Typically a rectangular active element, when combined together in a matrix, forms a character or symbol.

A passive matrix LCD (Liquid Crystal Display) technology that uses an extra compensating layer to provide a sharper image, sometimes called F-STN or Film Compensated Supertwist.

An enhanced STN passive matrix LCD (Liquid Crystal Display). The screen is divided into halves and each half is scanned simultaneously, thereby doubling the number of lines refreshed per second and providing a sharper appearance. DSTN is widely used on laptops and Point of Sale Terminals.

Newer version of the original passive matrix technology, where the screen is controlled by two processing systems. They are faster than "single scan" displays, but still slower than most TFTs. Dual Scan Passive Matrix displays are most useful where response speed is not critical.

A type of passive matrix LCD (Liquid Crystal Display) that provides faster refresh rates than conventional passive matrix displays by dividing the screen into two sections that are refreshed simultaneously.Dual scan displays are generally not as sharp or bright as active matrix displays, but they consume less power.

A technology used to produce a very thin display screen, called a flat panel display, used in some portable equipment. An ELD works by sandwiching a thin film of phosphorescent substance between two plates. One plate is coated with vertical wires and the other with horizontal wires, forming a grid.When an electrical current is passed through a horizontal and vertical wire, the phosphorescent film at the intersection glows, creating a point of light or pixel.EL Displays, being an emissive technology (rather than shuttering a light source as per LCDs) are most useful in applications where high visibility in all light conditions is essential.

A strip of silicone rubber made up of sequentially spaced conductive and non-conductive material. This is the most common connection method for LCD modules.

A phenomenon which occurs when excess DC voltage is applied to an LCD. Conductive particles from one piece of glass are transferred through the LC fluid and deposited on the conductive surface of the opposite piece of glass. A conductive spike is created thus causing a dead short.

A space left between the epoxy seals, after assembly on one end of the LCD glass. This space is used to fill the glass with the LC fluid, which is noted by a mound of epoxy on one end of the glass.

A very thin display screen used in portable computers. Nearly all modern flat panel displays use LCD (Liquid Crystal Display) technologies.Most LCD screens are backlit to make them easier to read in bright environments. Another example of a flat panel display is the gas plasma display screen.

A phenomenon occurring when voltage from an energized element leaks to an adjacent OFF element and turns the adjacent element partially ON. Also, the temporary trail left by a moving object on a "slow" LCD panel

Used exclusively on negative image graphic displays (transmissive negative). With EL or cold cathode backlight where the background is energized and the information to be displayed remains static or the same color as the polarizer in the OFF state. This is achieved by inverting the signal of the data lines before going to the LCD module.

A technique of improving the viewing angle of an LCD where the liquid crystal molecules are switched in the plane of the LCD layer rather than vertical to it.

When the fluid heats up or cools down to the point where the fluid is no longer in the twisted nematic state. The molecules can no longer twist light and, therefore, all incoming light is absorbed. In positive image displays, the viewing area turns completely dark. The display will revert back to the twisted nematic state when cooled below the isotropic temperature.

LCD, an abbreviation of Liquid Crystal Display, is a type of display used in digital watches and many portable devices. LCD displays utilize two sheets of polarizing material with a liquid crystal solution between them. An electric current passed through the liquid causes the crystals to align so that light cannot pass through them. Each crystal, therefore, is like a shutter, either allowing light to pass through or blocking the light.Monochrome LCD images usually appear as blue or dark gray images on top of a grayish-white background. Color Liquid Crystal Displays use two basic techniques for producing color. Passive matrix is the less expensive of the two technologies.The other technology, called thin film transistor (TFT) or active matrix produces color images that are as sharp as traditional CRT displays, but the technology is relatively expensive.Recent passive matrix displays using new CSTN and DSTN technologies produce sharp colors rivaling active matrix displays.Most Liquid Crystal Display screens used in notebook computers are backlit to make them easier to read.

A monitor that uses LCD (Liquid Crystal Display) technologies rather than the conventional CRT technologies used by most desktop monitors.Until recently, LCD panels were used exclusively in notebook computers (laptops) and other portable devices. In 1997, however, several manufacturers began offering full-size Liquid Crystal Display Monitors as alternatives to CRT monitors.The main advantage of LCD displays is that they take up less desk space and are lighter. Currently, however, they are also much more expensive

LCD (Liquid Crystal Display) is the technology used for displays in notebook, smaller computers, portable devices including Mobile Telecoms (Telecommunication) pagers, phones, PDAs, EPOS and other instrumentation monitors. Like light-emitting diode and gas-plasma technologies, LCDs allow displays to be much thinner than cathode ray tube (CRT) technology. Liquid crystal Displays consume much less power than LED and gas displays because they work on the principle of shuttering light rather than emitting it.LCD fluids are selectable for individual display projects, with TN the original technology and HTN, STN and F-STN being developments. Liquid crystal displays are the most popular display medium for applications large and small.An LCD is made with either a passive matrix or an active matrix display grid. The active matrix LCD is also known as a thin film transistor (TFT) display. The passive matrix LCD has a grid of conductors with pixels located at each intersection in the grid. A current is sent across two conductors on the grid to control the light for any pixel. An active matrix has a transistor located at each pixel intersection, requiring less current to control the luminance of a pixel. For this reason, the current in an active matrix display can be switched on and off more frequently, improving the screen refresh time (your mouse will appear to move more smoothly across the screen, for example).A typical liquid crystal display will incorporate the LCD fluid (either TN, STN, HTN or F-STN) in a glass envelope with ITO coatings to the internal glass surfaces. The basic liquid crystal display, either statically driven or multiplexed, is frequently incorporated onto a PCB (Printed Circuit Board) with the LCD display driver hardware and often backlighting, LED EL, or CCFL.Liquid crystal displays do not suffer degradation over time, the LCD fluids always return to their normal state when a voltage is not applied. Temperature does affect liquid crystal displays however, with extreme low temperature causing the LCD to respond very slowly. The required bias voltage across the liquid crystal display also alters with ambient temperature.Some passive matrix liquid crystal displays have dual scanning, meaning that they scan the grid twice with current in the same time that it took for one scan in the original technology. However, active matrix is still a superior technology.Temperature does affect liquid crystal displays, however with extreme low temperature causing the LCD to respond very slowly. The required bias voltage across the liquid crystal display also alters with ambient temperature

Also called a projection panel, it is a data projector that accepts computer output and displays it on a transmissive liquid crystal screen that is placed on top of an overhead projector.Liquid crystal display systems are also available with their own light source. Such units generally provide the best quality, because the light and lenses are fine tuned to the built-in LCD screen.

A form of backlighting for small to medium size LCDs that use surface mount LEDs on a substrate with a light diffuser over the top. In some cases LEDs are placed at each end of the module and light is directed into the center.

The compound found in liquid crystal displays. Liquid crystal reacts predictably when electrically stimulated. This makes it the ideal compound to turn LCD pixels "on" or "off." Liquid crystal is sometimes abbreviated as LC.

(Low Voltage Differential Signalling) A transmission method for sending digital information to a flat panel display. LVDS has been widely used in laptops because it enables fewer wires to be used between the motherboard and the panel. The technology is also used between the image scaler and the panel in many stand-alone flat panel displays.

For LCD Monitors designed in compliance with VESA Standard Physical Mounting Interface Standard (FPMPM), users may choose mounting solutions from professional arm manufacturers.

Unlike traditional CRTs that can display multiple resolutions, LCD displays are manufactured to best display a single resolution, known as the native resolution. While it may be possible to change the resolution of an LCD (depending on the video card and software used with the LCD), setting the resolution to something other than the native resolution will result in a stretched image, a blurry image, or no image on the screen at all. This is typically expressed as the number of pixels in a line by the number of lines, e.g. 1024x768. The native resolution may also be expressed in megapixels, which is calculated by multiplying pixels per line by total lines.

A twisted nematic LCD design where the backlight is blocked when pixels are in the unselected state. Therefore, when no voltage is applied, the screen is black.

A twisted nematic LCD design where light is transmitted when pixels are in the unselected state. Therefore, when no voltage is applied, the screen is white.

The predecessor to today"s projectors, (some are still available) they a thin (under 2") devices typically 10 x 14 inches. All panels are of the LCD variety. They lack their own light source, and instead, sit on top of a overhead projector (OHP). Although panels are light (5-8LB.), even on specially designed, extremely bright, overhead projectors, they produce dim images useable only in darkened rooms on small screens.

A common type of flat panel display consisting of a grid of horizontal and vertical wires. At the intersection of each grid is an LCD (Liquid Crystal Display) element which constitutes a single pixel, either letting light through or blocking it.A higher quality and more expensive type of display, called an active matrix display, uses a transistor to control each pixel. In the mid 1990"s, it appeared that passive matrix displays would eventually become extinct due to the higher quality of active matrix displays. However, the high cost of producing active matrix displays and new technologies such as DSTN, CSTN and HPA that improve passive matrix displays, have caused passive matrix displays to make a surprising comeback.

The original LCDs, these are controlled by a single processing system, for the whole screen, unlike active and poly-si, which have descrete circuits for each "pixel." This results in a panel with terrible color dynamics and contrast (typically 15:1). They are also incredibly slow: On passive laptop computers, the cursor (or anything else) moving on the screen, goes invisible until you stop moving it (submarining) Only one or two projectors use any type of passive matrix display.

Picture element (see Dot/Pixel). Pixels are tiny picture elements comprised of three subpixels (one red, one green, and one blue.) Although a single pixel displays one color, collectively those pixels create a complete image recognizable by the human eye. A single LCD consists of thousands, even millions of pixels.

A pixel anomaly is a pixel that displays only one color (white, black, red, green, or blue.) These are commonly referred to as "stuck" or "void" pixels. If a pixel on an LCD appears to be stuck on one color, it will sometimes come back to life by gently massaging the pixel and the area surrounding it in a circular pattern. (For obvious reasons, pixel massage will not work on a CRT.) A small number of pixel anomalies are considered normal, or at least inevitable, on LCDs. The number of pixel anomalies it takes for a display to be considered defective varies by hardware manufacturer.

A light filter which only allows light waves of a certain rotation through. Polarized material with perpendicular filtering is used in LCDs to enclose the liquid crystal. The liquid crystal is then used as the medium which twists the light waves 90� in order to allow the light to pass through or not.

Are made of a polymer acetate with iodide molecules incorporated in the material. The molecules are arranged to only allow scattered light to enter in one plane/axis. Twisted nematic LCDs require two polarizers, one on the front and one on the back.

The "hot" LCD technology for the top of the line LCD projectors. Poly-Sci is typically 3 separate layers of LCDs, one each for Red, Green and Blue. This results in increased color dynamics, with contrast ratios around 200:1. Poli-Si technology is also a bit faster than the Active Matrix TFT, for smooth video and multimedia.

Typically a smooth silver/gray piece of polished aluminum foil bonded to the rear polarizer. Reflects the incoming ambient light. Note: Backlighting can not be used with a reflective type LCD.

Applicable to CRTs but not LCDs, refresh rate equals the number of times per second that the electron gun redraws the image on the screen. For example, if a CRT"s refresh rate is set to 60 Hz, the screen image will be redrawn 60 times a second. Low refresh rates will cause the image to flicker, resulting in eye strain or other problems. For this reason, refresh rates on CRTs should be set as high as possible

This figure indicates how quickly an LCD panel can display a change in the brightness of the screen image. It is calculated as the sum of the times needed for the image to change from 10% to 90% of its maximum brightness, and from 90% to 10%. Faster response times allow a smoother display of rapidly-changing screen images, such as real-time video.

LCD driver or controller electronics are encapsulated in a thin, hard bubble package, of which the drive leads extend from the bubble package on a thin plastic substrate. The adhesive along the edges is used to attach the TAB to the LCD glass and/or PCB.

Definition 1:Abbreviation of thin film transistor, a type of LCD (Liquid Crystal Display) flat panel display screen, in which each pixel is controlled by, from one to four transistors. The TFT technology provides the best resolution of all the flat penal techniques, but it is also the most expensive. TFT screens are sometimes called active matrix LCDs.Definition 2:This term typically refers to active matrix screens on laptop computers. Active matrix LCD (Liquid Crystal Display) provides a sharper screen display and broader viewing angle than passive matrix screens.

There are two primary technologies used for touch screens and both use a clear glass panel overlaid onto the CRT or LCD screen. The resistive method is completely pressure sensitive. It uses a plastic layer on top of a metallic-coated glass layer, separated by spacers. When pressed, it shunts the current in the glass panel, and the x-y coordinates pick up the location on the screen.

A type of LCD which does not have a reflector or transflector laminated to the rear polarizer. A backlight must be used with this type of LCD configuration. Most common is transmissive negative image.

CRT image size is advertised as the diagonal measure of the glass in the display (15", 17", etc.) However, the viewable area, or the size of the image a monitor can actually display, is usually one to two inches less than the advertised size. LCD image size is usually identical to what is advertised, as the physical picture tube border present on CRTs (the space between the viewable area on the CRT and the plastic chassis) is not present on LCD displays.

The dimensions measured from the inside perimeter of the LCD bezel or LCD glass epoxy seal. The viewing area defines actual area that can be illuminated when the entire screen is turned ON (white).

Same as- Elastomer Connector which is a strip of silicone rubber made up of sequentially spaced conductive and non-conductive material. This is the most common connection method for LCD modules.
