Miniature Flat Panel Display Feasibility Model

摘要

Development efforts toward producing a matchbox-size miniature TV system using a thin film electroluminescence (TFEL) display are summarized. Potential applications include thermal weapons viewing sight and low mass head-mounted display systems. Results of the program include high density TFEL display surface (692 X 540 pixels at 500 lines/inch density), high density interconnect to display surface, and techniques for fabricating high density polyimide/copper hybrid circuits to provide an integrated miniature display system package. Procurement of high voltage driver ICs was a major hurdle. Upon receipt of these ICs TV imagery was demonstrated on a compact breadboard system using a 320 x 250 pixel TFEL display with 250 lines/inch resolution. Breadboard power measurements indicate a power requirement of 2.4 watts using existing components or 1.7 watts with improvement in the IC driver chip. (Author)
