ABSTRACT:
A system and technique for controlling LCDs based upon measurement of optical response is disclosed, which includes a light source and a light detector on opposite sides of an independently driven test area of a LCD panel. A determination of the optical response time is made by comparing the varying signals from the LCD drive and the response detector and then changing the operation of the LCD panel or heater based upon the comparison.
