Patent ID: 6930663

Claim:
A liquid crystal display device, comprising: a liquid crystal cell forming an image display area; a driver for applying a voltage to said liquid crystal cell; an overdrive controller for controlling said driver to apply an overdrive voltage exceeding a targeted pixel value to said liquid crystal cell, wherein said overdrive controller controls such that the driver outputs the voltage to accelerate or decelerate a brightness transition for each sub-pixel in order to make up effective brightness of each sub-pixel which forms a single full-pixel; wherein said overdrive controller selects the overdrive voltage for the sub-pixel exhibiting the slowest transition of brightness and selects the voltage to accelerate or decelerate a brightness transition for the other sub-pixels in order to coordinate with the sub-pixel exhibiting the slowest transition; and wherein said overdrive controller stores predicted capacitance for each of the sub-pixels and calculates the voltage to accelerate or decelerate a brightness transition for each sub-pixel in order to coordinate with each other based on the predicted capacitance.
