Abstract
A driving system capable of supporting multiple display modes is provided. The driving system includes a memory for storing gamma codes corresponding to various display modes, a gamma voltage generation device producing gamma voltages corresponding to the gamma codes, and a timing controller accessing the gamma codes stored in the memory and writing the gamma codes into the gamma voltage generation device according to mode switch signals. The gamma voltage generation device then produces gamma voltages corresponding to the input gamma codes during the vertical blank interval of the display device, thereby achieving display mode switch. The memory may also be integrated in the timing controller. Compared to the prior art, the driving system is compatible with various display modes with reduced cost.
