Abstract
A display driver that includes a first driver integrated circuit being cascaded to a second driver integrated circuit is introduced. The first driver integrated circuit includes a first gamma voltage generator that is configured to output a plurality of first gamma voltages to output terminals of the first gamma voltage generator. The second driver integrated circuit includes a second gamma voltage generator that is configured to output a plurality of second gamma voltages to output terminals of the second gamma voltage generator. Each of the output terminals of the first gamma voltage generator is corresponded to one of the output terminals of the second gamma voltage generator. At least one of the output terminals of the first gamma voltage generator is electrically coupled to the corresponding one of the output terminals of the second gamma voltage generator to output at least one common gamma voltage of the first gamma voltages and the second gamma voltages. A method adapted to the display driver is also introduced.
