Miniature Active Matrix Display.
Abstract
The purpose of this research is to take a step toward the development of a miniature flat panel display system in order to replace the miniature CRT now found in Helmet Mounted Displays. This research further attempts to advance projected uses in hand-held and weapon mounted target acquisition devices. The flat panel display would result in reductions in system size, volume, weight, power, voltage and cost relative to a CRT system. In addition, new system configurations would be possible as a result of the compactness of the flat panel system. Flat displays using solid state electronics and various display media have already been developed as commercial products. In most of these, discrete light emitting or modulating elements are electronically addressed and activated. However, when high resolution is required, the large number of such elements results in difficult problems relating to element addressing, electrical connections, duty cycle, and power requirements. Over the past seven years, an intensive program at Westinghouse on the development of thin film transistor (TFT) circuits has made it possible to incorporate active circuitry within each display element, and has made it further possible to provide addressing with peripheral scanner circuitry in the same planar substrate as the display.
