Patent ID: 7345668

Claim:
A method of driving a liquid crystal panel which displays grayscale levels by applying a driving signal to a pair of electrodes having liquid crystal interposed therebetween and displays white when no voltage is applied, the driving signal having a pulse width that is modulated according to the grayscale level, the method comprising the steps of: detecting at least one of a temperature of the liquid crystal panel and a temperature of a surrounding environment in which the liquid crystal panel is disposed; discriminating whether the detected temperature is a predetermined threshold value or more; and if the detected temperature is discriminated to be the threshold value or more, defining the pulse width according to the grayscale level such that the pulse width of the driving signal is gradually decreased as the grayscale level becomes bright, and if the detected temperature is discriminated to be less than the threshold value, changing the pulse width such that the pulse width corresponding to the brightest grayscale level is larger than the pulse width corresponding to that at which the temperature is the threshold value or more.
