Paper Abstract

This paper reports the development of engineering prototypes of a video data, and video clock, to those required by the panel. The driver high-information-content electroluminescent flat-panel monitor, the board contains the specialized high voltage IC circuitry for the EL panels. 6648M. The monitor is based on an EL display with 256 rows and 512 This circuitry is implemented with the new TI SN7555X-series devices. columns (131,072 pixels) with a pitch of 66.7 lines per inch. This panel Maximum compactness is achieved by extensive use of surface-mounted has the capability to display a full 25 lines of 80-character text or high- device technology and an innovative panel-to-circuit-board interconnect resolution graphics with all the advantages that make EL displays so system. This permits the entire panel/driver module to be packaged into desirable, i.e. high-contrast, crisp and flicker-free images, exceptional a unit with dimensions of 5.7 x 10.3 x 0.75 inches. The controller board linearity, all in a very compact and rugged package. has the same dimensions as the driver board, which gives the user the In addition to the panel, the monitor consists of a driver board and a flexibility of packaging the entire unit in a depth of 2 inches or 0.75 controller board. The controller board converts the signals provided by inches with a remotely located controller board. the user's standard CRT controller, i.e. vertical sync, horizontal sync,video data, and video clock, to those required by the panel. The driver board contains the specialized high voltage IC circuitry for the EL panels. This circuitry is implemented with the new TI SN7555X-series devices. Maximum compactness is achieved by extensive use of surface-mounted device technology and an innovative panel-to-circuit-board interconnect system. This permits the entire panel/driver module to be packaged into a unit with dimensions of 5.7 x 10.3 x 0.75 inches. The controller board has the same dimensions as the driver board, which gives the user the flexibility of packaging the entire unit in a depth of 2 inches or 0.75 inches with a remotely located controller board.
