摘要：
In a display control apparatus for applying to a display panel first gamma voltages within a first voltage region with reference to two first reference voltages, a gamma voltage generating circuit is adapted to generate second gamma voltages within a second voltage range. A maximum voltage of the second voltage range is lower than a maximum voltage of the first voltage range. At least one digital-to-analog converter is adapted to select one of the second gamma voltages in accordance with a digital video data signal, and at least one output buffer is adapted to step up the selected one of the second gamma voltages into a respective one of the first gamma voltages. The respective one of the first gamma voltages is applied to the display panel.
