LARGE-AREA ELECTRONIC DISPLAY PANEL.
Abstract:
The objective of the Project is to advance the state-ofthe-art of Large-Area Electronic Display by developing a new high-resolution electron beam deformation system for thermoplastic film and a novel optical projection system. A total internal reflection projection system TIRP is being developed which will project a 50 x 50 mm format with 3,000 resolvable elements per side dimension to an 8 x 8 foot screen with a light flux in excess of 2,000 lumens. This novel optical projection system permits simultaneous writing and projection in the same station with a high resolution magnetic-deflection electron gun. An objective with this performance is presently being fabricated. Electron optical development has produced an electron gun capable of writing a 3,000 line raster in one-half second on thermoplastic. This gun has successfully recorded 18.87 mc video using stretch modulation. Dynamic corrective waveforms are required. The main effort on electron optics, is aimed at achieving uniform records and acceptable stability under conditions of single-frame writing. Author
