MATRIX CONTROLLED DISPLAY DEVICE
Abstract
Progress is reported on a large screen, matrix controlled display device using in-air surface deformation recording and TIRP (Total Internal Reflection Prism) projection technique. The TIRP projection system for the optical readout of surface deformations on a thermoplastic or an oil medium was designed and implemented. Its operation is explained. Optical design considerations are given based on a 64 x 64 element display. The mechanical adjustments required for the alignment of the TIRP optical system and to provide a uniform air gap for in-air recording are discussed. The implementation of the in-air recording technique using X-Y matrix control was also completed. Circuitry to drive any desired combination of X-Y matrix electrode intersections at the display medium is described.
