Patent ID: 7804470

Claim:
A method for driving a liquid crystal display device, the method comprising: identifying an ambient temperature; extracting an overdrive parameter from a lookup table containing a plurality of overdrive parameters, each overdrive parameter corresponding to a graylevel transition between a first and a second frame and representing a level at which a liquid crystal is driven in order to achieve a response time for the graylevel transition; and applying a temperature adaptive algorithm to the overdrive parameter extracted from the lookup table to determine an adapted overdrive parameter that adjusts for a difference between the identified ambient temperature and a reference temperature at which the extracted overdrive parameter is calibrated; and wherein the temperature adaptive algorithm calculates the adapted overdrive parameter ‘M T1 (i,j)’ according to the following equation: M T1 ( i,j )= M T0 ( i,j )+ D ( i,j ) where ‘M T0 (i,j)’ is the overdrive parameter extracted from the lookup table for the start graylevel ‘i’ and the target graylevel ‘j’, and ‘D(i,j)’ is a compensation parameter to compensate for the difference between the identified ambient temperature and the reference temperature.
