Abstract :
A 64×64 element matrix array of amorphous-silicon thin-film transistors has been fabricated on a glass substrate. Using a drive scheme to simulate a 500-line display, an output voltage of 8.5 V RMS is obtained. This large output voltage is sufficient for an alphanumeric liquid-crystal display using the dyed cholesteric-nematic phase-change effect. The driving voltages for the array are compatible with LOCMOS (18 V) peripheral circuitry.
