Abstract
System and method for driving an LCD using a data-dependent, logic-level drive scheme. A preferred embodiment comprises determining a desired state of each pixel in an LCD pixel segment, deriving a drive waveform based upon the state of all pixels in the LCD pixel segment, and outputting the drive waveform to the LCD pixel segment. By using the states of all the pixels in the LCD pixel segment in the determination of the drive waveform, it is possible to increase the on and off voltage to help improve display quality.
