Abstract: A gamma correction apparatus comprising a digital to analog converter (DAC), a plurality of compensating circuits, and at least one adjusting circuit is provided. The DAC is used to receive RGB digital signals to further generate analog signals. The analog signals are then transferred to the relative pixel devices through the signal lines on the LCD panel. The compensating circuits inserted between the DAC and the signal lines are used to adjust the analog signals to correct the displaying brightness of the pixel devices. The adjusting circuit connecting to the compensating circuits is used to control the operation of the compensation circuits. In addition, a method for adjusting gamma curves by providing three common voltage levels related to RGB colors individually is also provided to achieve better white balance.
