Design of LCD for Electronic Instrument Cluster 850301
Liquid Crystal Display panels have been applied to automotive instrument clusters for many years. As a result of the stringent automotive environmental and viewing conditions, most applications have featured the transmissive negative display mode (dark background, transmissive on segment).
Technologies for improvement of visibility, electrical interconnect, and backlighting have developed rapidly and are still being explored to achieve further improved performance. Additionally, processing concepts and in-process automation have developed to the point that long term reliability and consistent high quality is currently achievable.
