Dynamic gamma control12/28/2023 The dynamic gamma control method according to claim 5, wherein X 2 is greater than X 1 and X 3.ħ. The dynamic gamma control method according to claim 4, wherein the equation of luminance of the LCD is Y=X 1R+X 2G+X 3B, where Y is the gamma indication value, X 1 to X 3 are three user defined parameters, R is a sum of the red pixel data, G is a sum of the green pixel data, and B is a sum of the blue pixel data.Ħ. The dynamic gamma control method according to claim 1, wherein the part of the input data comprises: a part of red pixel data of the present frame a part of green pixel data of the present frame and a part of blue pixel data of the present frame.ĥ. The dynamic gamma control method according to claim 1, further comprising: if the gamma indication value is not equal to the predetermined value, maintaining the first gamma reference voltages for the next frame, thereby the present frame and the next frame are corresponding to a same gamma curve.Ĥ. The dynamic gamma control method according to claim 1, wherein the first gamma reference voltages are corresponding to a first gamma curve from one of the two different gamma curves, and the second gamma reference voltages are corresponding to a second gamma curve from the other of the two different gamma curves.ģ. A dynamic gamma control method, suitable for a liquid crystal display (LCD), the dynamic gamma control method comprising: receiving input data of a present frame, and providing a plurality of different first gamma reference voltages for the present frame to a source driver IC analyzing only a part of the input data uniformly distributing on the present frame by an equation of luminance of the LCD under a condition of without using a frame memory, so as to obtain a gamma indication value determining whether the gamma indication value is equal to a predetermined value and if the gamma indication value is equal to the predetermined value, changing the first gamma reference voltages, so as to obtain and provide a plurality of different second gamma reference voltages for a next frame to the source driver IC, thereby the present frame and the next frame are corresponding to two different gamma curves.Ģ.
