Abstract: A first driver circuit is configured to cooperate with a second driver circuit to control a display panel, wherein the first driver circuit is configured to output display data to a first area of the display panel and the second driver circuit is configured to output display data to a second area of the display panel. A method used for the first driver circuit includes outputting at least one emission control signal to control the second area of the display panel when the second driver circuit is disabled.
