DRIVING CIRCUIT AND METHOD FOR DRIVING A DISPLAY

摘要

In one aspect of the invention, a driving circuit for driving a display having pixels spatially arranged in a matrix form, includes an input interface for processing input image signals into pixel signals associated with the pixel matrix and grayscales of the display; a timing controller for generating a polarity control signal; a pair of multiplexors electrically coupled to the input interface for receiving the pixel signals therefrom and controlled by the polarity control signal for selecting transmitting paths of the parallel pixel signals; a data register electrically coupled to the pair of multiplexors for stored the pixel signals including its transmitting paths determined by the polarity control signal; and a source driver having a latch array electrically coupled to the data register for receiving the stored pixel signals therefrom, the source driver configured to write the stored pixel signals into the pixel matrix according to the polarity control signal.
