Miniature Active Matrix Display.
Abstract
The objective of this program was the development of fabrication methods for an active matrix, flat panel TV display with a resolution of at least 400 elements per linear inch. The feasibility of such a high-resolution, solid-state, flat panel screen was demonstrated for the first time using thin film electroluminescence as the display media. A resolution of 500 lines per inch with an active area to total area ratio of greater than 0.7 was achieved. The demonstration display panel consisted of 100x100 active elements. Simulated scanning conditions for line-at-a-time addressing yielded a time average brightness of up to 7 ft-L under 1/500 duty cycle excitation. This advance indicates that high-resolution, solid-state, flat panel TV display devices are feasible. Further work is required in order to produce a full 500x500 pixel element display including development of line-at-a-time scanning electronics with the associated interface to the display surface.
