Abstract
Abstract— A new touch‐sensitive hydrogenated amorphous‐silicon (a‐Si:H) display with embedded optical sensor arrays is presented. The touch‐panel operation was successfully demonstrated by fabricating a prototype of a 16‐in. active‐matrix liquid‐crystal display (AMLCD). The proposed system, obviating the need for the extraction of information from the captured images in real time, provides the location of the finger touch. Due to the simple architecture of the system, the touch‐panel operation can be readily integrated within large‐area displays.
