Zusammenfassung:A gamma correction circuit applied in a displayer comprises a first storage unit, a second storage unit, a first correction circuit and a second correction circuit. A first gamma lookup table is stored in the first storage unit, and a second gamma lookup table is stored in the second storage unit. The first correction circuit receives an input signal and generates a middle signal corresponding to the input signal according to the first gamma lookup table, the second correction circuit receives the middle signal and generates an output signal corresponding to the middle signal to a display panel according to the second gamma lookup table, and the first gamma lookup table is stored in the first storage unit after the displayer is started.
