| Zusammenfassung: | The present invention discloses a gamma correction circuit capable of eliminating band mura of a flat panel display and method thereof. The gamma correction circuit comprises a plurality of operational amplifier. A plurality of reference voltages may be generated via a plurality of reference points of the gamma correction circuit. The reference voltages may be used to generate voltages with various levels via the resistance circuit inside the gamma correction circuit in order to generate a variety of color levels. In particular, the exchange rate between the non-inverting input and the inverting input of each of the operational amplifiers is increased, such that the output waveform of the operational amplifier will be reduced and become stable. |
