MATRIX CONTROLLED DISPLAY DEVICE, PHASE II.
Abstract
The progress in a program to develop a feasibility model of a bright, large screen matrix type display using in-air thermoplastic recording and TIRP (Total Internal Reflection Prism) projection techniques is reported. A brief summary of the Phase I program is given prior to discussing the current Phase II effort. The test setup to provide a 25 x 25 elemental portion of the large screen display by optical readout of deformations on a thermoplastic medium is described. Control of the in-air recording process by an X-Y matrix to provide individual storage of information is discussed. Techniques to be employed for fabricating a 25 line matrix with electrodes at 500 line pairs per inch are listed. The results are given for the several fabrication processes which have either been completed or have commenced. These include the preparation of artwork and a photographic mask, exposure of a photosensitive resist to form the reverse image of the matrix electrodes prior to etching, and the coating of glass plates to be used for matrix substrates with a transparent conductive film of indium oxide. Initial experiments with electroless copper plating were performed and are described. The fabrication of a 2000 line matrix, which is to be initiated during this contract, is discussed. (Author)
