The environment of the automobile poses severe challenges to AMLCD technology. Among automotive display applications, the primary instrument, or instrument cluster, is the most demanding due to the safety concerns of display shortcomings or failure.
This paper will address and summarize issues involving the application of AMLCD display technology to the primary instrument. The results of environmental testing of ruggedized automotive AMLCD modules will be presented, without revealing the display module manufacturers' names.
The paper will also reveal the results of supplemental testing of these AMLCD modules. Tests that characterize AMLCD display performance such as contrast, brightness, response time and viewing angle performance vs. ambient temperature will be presented.
