Abstract

In a novel liquid crystal cell overdrive method, the actual voltage, on the liquid crystal cell (11), resulting from the previous frame drive operation is measured, and the amount of the overdrive voltage is evaluated from this actually measured voltage. This method allows implementing the overdriving method without the use of a frame memory because it uses the intrinsic capacitance (CLC) of the liquid crystal cell (11) as a memory element. Moreover, this method allows a more accurate overdrive amount because its evaluation is based on the actual voltage present at the liquid crystal cell (11) resulting from the previous frame.
