Abstract
The analog drive circuit drives a pixel electrode in response to an analog sample derived from a video signal. The analog drive circuit comprises a sample selection section and a drive signal generator. The sample selection section receives and temporarily stores the analog sample during a sample load period. The drive signal generator generates a drive signal and applies the drive signal to the pixel electrode during a display period that follows the sample load period. The drive signal is composed of a sequence of a first temporal portion and a second temporal portion. The first temporal portion has a time duration substantially proportional to the analog sample temporarily stored in the sample selection section. The second temporal portion is the temporal complement of the first temporal portion.
