Abstract:
1. A liquid crystal display apparatus comprising: a liquid crystal display module configured to receive RGB picture signals from outside the liquid crystal display module and further configured to display images based on the received RGB picture signals, the liquid crystal display module comprising: a control module configured to receive the RGB picture signals and to generate one or more control signals indicative of a gamma value, wherein the control module includes a digital to analog (D/A) converter configured to receive data indicative of the RGB picture signals and to generate the one or more control signals indicative of the gamma value; and a voltage generator unit, of the liquid crystal display module, configured to receive the one or more control signals and to generate a plurality of gray scale voltages corresponding to the gamma value, wherein the plurality of gray scale voltages corresponding to a first gamma value is different than the plurality of gray scale voltages corresponding to a second different gamma value, wherein the gamma value depends on an average value of the RGB picture signals for a predetermined period.
