Thin Film Transistor-Addressed Display Device.
Abstract
The goal of this program is the development of a data display that will incorporate all the traditional advantages of solid state technology viz, reliability, compactness, low power, and lack of fragility. To initially accomplish this the authors are developing a 6 inch x 6 inch 20 lpi dot matrix display; the medium is ac-electroluminescence. The key aspect is the fabrication of an integral thin-film transistor addressing matrix that allows individual elemental control of each picture point. Significant progress was made towards optimizing the TFT properties i.e. obtaining the desired ON:OFF ratio required for correct operation of the circuit. In particular ON currents of > 300 microamps have been achieved with OFF currents approximately 1 microamps; these OFF currents need further improvement as yet. Voltage handling > 100V was achieved.
