The dynamic gamma control method as claimed in claim 7, wherein said LCD is a TFT-LCD.ĩ. A dynamic gamma control method for an LCD displaying a present frame by a plurality of gamma reference voltages, comprising steps of: obtaining an R-pixel data sum, a G-pixel data sum and a B-pixel data sum by respectively adding all R-pixel data, all G-pixel data and all B-pixel data of at least one pixel of said present frame weighting said R-pixel data sum, said G-pixel data sum and said B-pixel data sum with a first, a second and a third parameters respectively and adding them up to obtain a gamma indication value and choosing a suitable one from said plurality of gamma reference voltages to display said present frame thereby if said gamma indication value is equal to a gamma reference value formed by adding said first, said second and said third parameters up.Ĩ. The dynamic gamma control method as claimed in claim 5, wherein said LCD further comprises a driver IC for driving said LCD by said suitable gamma reference voltage.ħ. The dynamic gamma control method as claimed in claim 4, wherein said LCD further comprises a multi-channel digital-to-analog converter (DAC) for receiving said gamma indication value and sending said suitable gamma reference voltage.Ħ. The dynamic gamma control method as claimed in claim 3, wherein said ASIC further comprises a low voltage differential signaling (LVDS) circuit and a timing controller.ĥ. The dynamic gamma control method as claimed in claim 1, wherein said LCD comprises an application specific integrated circuit (ASIC) for operating said dynamic gamma control method.Ĥ. The dynamic gamma control method as claimed in claim 1, wherein said LCD is a TFT-LCD.ģ. A dynamic gamma control method for an LCD, wherein said LCD displays a present frame by a plurality of gamma reference voltages, and said present frame comprises an R-pixel data sum, a G-pixel data sum and a B-pixel data sum which are obtained by respectively adding all R-pixel data, all G-pixel data and all B-pixel data of at least one pixel of said present frame, comprising steps of: weighting said R-pixel data sum, said G-pixel data sum and said B-pixel data sum with a first, a second and a third parameters respectively and adding them up to obtain a gamma indication value and choosing a suitable one from said plurality of gamma reference voltages to display said present frame thereby if said gamma indication value is equal to a gamma reference value formed by adding said first, said second and said third parameters up.Ģ.
