Abstract:
A method and system for calculating an overdrive parameter for a liquid crystal within an LCD device to compensate for temperature variations. An example system includes a temperature sensor for measuring an ambient temperature near a liquid crystal and a memory for storing a lookup table containing a plurality of overdrive parameters. Each overdrive parameter corresponds to a graylevel transition between a previous frame and a current frame, and represents a level at which a liquid crystal is driven in order to achieve a desired response time for the graylevel transition at a reference temperature. A processor extracts the appropriate overdrive parameter from the lookup and calculates an adapted overdrive parameter that adjusts for the difference between the measured ambient temperature and the reference temperature.
