DISPLAY DRIVE INTEGRATED CIRCUIT AND IMAGE DISPLAY SYSTEM

摘要

A display drive integrated circuit includes a frame buffer, an output selector and a timing controller. The output selector selectively outputs one of image data read from the frame buffer and image data transmitted from a source external to the display drive integrated circuit. The timing controller controls output of the image data read from the frame buffer to the display panel in a self-refresh mode, and controls internal display timing to track external display timing when the display drive integrated circuit exits from the self-refresh mode to control the output selector to output the image data transmitted from the source to the display panel when the internal display timing is synchronized to the external display timing.

1. A display drive integrated circuit comprising:
a frame buffer; an output selector configured to selectively output one of image data read from the frame buffer and image data transmitted from a source external to the display drive integrated circuit; and a timing controller configured to control output of the image data read from the frame buffer to a display panel in a self-refresh mode, and control internal display timing to track external display timing when the display drive integrated circuit exits the self-refresh mode to control the output selector to output the image data transmitted from the source to the display panel when the internal display timing is synchronized to the external display timing.
