This article describes a personal computer (PC)-based tester which verifies the operation of an automotive display assembly comprised of a five-inch diagonal viewing area cathode ray tube (CRT) monitor, a display-oriented touch-input device consisting of a soft switch matrix, a hard switch matrix and back lighting, and a touch controller decode logic board. The controller logic decodes the soft (touch input) and the hard switch matrices. This assembly meets the requirements of the automotive environment. Fig. 1 is a block diagram showing the CRT monitor assembly interfaced to an advanced display controller (ADC) 1 and wiring harness 2 of an automotive vehicle. The assembly consists of the monitor 3, the touch controller board 4 and the touch input device 5.
