Liquid Crystal Displays
 Advances in
liquid crystal display (LCD) technology are promoting the technology for growing range of flat-panel applications. Common applications of LCDs in low cost alphanumeric displays in watches and calculators and low-end laptop computers are now being accompanied by advanced LCD video-graphics terminals and high-performance monochrome and color LCD desktop and laptop computer displays.

The new technologies driving this growth in applications include supertwist, double-supertwist, and active-matrix (using thin-film transistors) monochrome and color LCDs. These have improved contrast, viewing angle and resolution. Several advanced LCD products using the new technologies are briefly described.
Liquid crystal displays (LCDs) continue to change the way people view information. From the ubiquitous 7-segment character displays to the large-are displays used in portable computers, LCDs are making a strong bid to dominate the flat-panel-display market. In their simplest forms, LCDs offer users many advantages. They are inexpensive, thin, durable, and lightweight, and they consume very little power. Their major disadvantages have been poor contrast, low brightness, and a narrow viewing angle. Until a few years ago, these disadvantages restricted the use of LCDs to low-performance applications such as digital watches and calculators, simple alphanumeric displays, and inexpensive laptop
computers.
But this situation is changing. Improved technologies such as supertwist, double supertwist, and thin-film transistors have not only greatly improved the contrast and viewing angle of simple displays but have also expanded the application base for
liquid crystal displays. Large-area displays utilizing these technologies are suitable for high-performance computers and video-graphics terminals. Large-area color LCDs are also becoming available and, together with their monochrome siblings, are making a strong bid to replace other types of flat-panel and, ultimately, the cathode-ray tube.

Although large, high-resolution displays may represent the state of the art and are undoubtedly the most interesting LCDs, smaller displays, including segmented and dot-matrix types, account for the largest share of the market. These types of
liquid crystal displays find application in such diverse products as gasoline pumps, medical instruments, test equipment, printers, typewriters, automotive-dashboard displays, industrial controls, and even games and
toys. See also Flat Screen TFT Displays, and pages relate to Liquid Crystal Displays
