Abstract:
A circuit for a flat panel display, capable of displaying images, is provided. The circuit includes an image storage block for storing the images to be displayed, a display and timing controller block controlling the display operation, an image pixel matrix containing a multitude of rows and columns arranged pixel elements. The circuit also includes one or more controlled row driver blocks, one or more controlled column driver blocks, and a pixel pre-charge mechanism for pre-charging the pixel elements employing a back to back pre-charge operation applied to a row and/or column drive activated pixel element display operation. The back to back pre-charge operation signifies that during every other operating sequence a pre-charge operation is replaced by an activated pixel element display operation.
