Abstract

The paper describes a system developed for the automatic performance testing of self-illuminating display panels used, for example, in automobile dashboard instrumentation. The system employs a high resolution TV camera to view the displays; the image being analysed in a microcomputer system using special-purpose software. The change from moving needle instruments to electronic displays, which employ vacuum fluorescent, LCD and LED technologies, forces a new testing philosophy on manufacturers. The system performs 64 tests on the panels in approximately 45 seconds, which is considerably faster than a human operator could achieve.
