Abstract
An online gamma adjustment system of liquid crystal panel is disclosed. The system includes a port receiving a gamma encoding for adjusting from an external gamma adjustment device, and generating an enable signal; a storage device storing the gamma encoding for adjusting received by the port according to a voltage level status of the enable signal; a controller selectively reading the gamma encoding from the storage device according to voltage level status of the enable signal; and a gamma register receiving the gamma encoding read by the controller, outputting a gamma voltage corresponding to the gamma encoding read by the controller in order to drive a liquid crystal panel.
