Patent ID: 8284179

Claim:
A display device, comprising: a host adapted to generate a first image signal, the host being a video grid array (VGA) system; a timing controller connected with the host and comprising a memory, wherein the timing controller is adapted to generate a second image signal for driving image display; and a panel connected with the timing controller, wherein the panel is adapted to receive the second image signal for displaying image frames; wherein the host is configured to send a first control signal to the timing controller to trigger the start of a transition phase in preparation of a switch to a power-saving mode of operation, and to shut down once the transition phase ends, wherein the first control signal includes information related to a predetermined amount of image data to store in the memory; in response to the first control signal, the timing controller is configured to store image data in the memory that are used for display by the panel in the power-saving mode of operation, and output a second control signal to the host when the image data stored in the memory during the transition phase reaches the predetermined amount, thereby ending the transition phase.
