Source driving module generating two groups of gamma voltages and liquid crystal display device using same

摘要

A source driving module is disclosed, for providing a data signal to a display panel. The source driving module includes a gamma voltage generator, and a data driver receiving a gamma voltage outputted from the gamma voltage generator and generating a corresponding data signal to a display panel according to the gamma voltage. Wherein, the gamma voltage generator includes a first gamma generator and a second gamma voltage generator, the first gamma generator outputs a first gamma voltage, and the second gamma generator outputs a second gamma voltage. Wherein, the source driving module further comprises a voltage selector adapted for selecting one of the first gamma voltage and the second gamma voltage in a same moment to input to the data driver. A liquid crystal display device including the source driving module is also disclosed.
