Abstract: A method, system and computer program product for a display system driving a display device is provided. The display system includes a processor, a primary display controller, a secondary display controller and the display device. The primary display controller receives display data that is sent by the processor. The primary display controller also drives the display device when the processor sends new display frames. When these display frames are sent by the processor continuously, control of the display device is switched to the secondary display controller, which is optimized for a low-power operation.
