AM-LCDs bring solid-state devices to the display

Abstract

Today the cathode-ray tube (CRT), stemming from a well-known branch of vacuum electron devices, dominates the display market. However, through the maturing of active-matrix addressed liquid crystal displays, semiconductor technology has made its way into display applications that have until recently been reserved to CRTs. Amorphous silicon based thin film transistors (TFTs) are predominantly used as devices for driving the picture elements (pixels). Future developments regarding material and device structures are described. Based on these developments and strong investments in processing equipment and productivity, it is believed that LCD technology will penetrate display applications ranging from personal digital assistants and digital cameras to . on-vehicle use and desk-top monitors,. Display diagonals will range between 1 and 40 inches are possible, commercially reaching 21-inch before the year 2000.
