Automated System for Response Time and Flicker Optimization in LCDs

One of representative techniques for compensation of LC's slow response characteristic is the Response Time Acceleration (RTA) technique. The conventional data definition for the RTA is based on the manual measurement and thus it takes long time. Therefore it is almost impossible to use panel specific compensation data in MP line. We have developed a new automated measurement system and flicker minimization for this purpose, which could achieve dramatic measurement time reduction, consistency over different operator, and optimized values as well. This system laid the groundwork for the application of image quality enhancement technologies to panels individually, and using this system, we can expect very uniform image quality for all LCD panels.
