ABSTRACT:
A method of overdriving LCD panels to improve LCD pixel response time is described that does not rely upon conventional use of overdrive look up tables. The method is based upon modeling the LCD pixels as linear second-order dynamical systems that leads to simple runtime calculations requiring but a small number of stored panel specific constants.
