Drive circuit of display and method for calibrating brightness of display

A drive circuit of a display for driving at least a pixel, comprising:

• an output stage coupled to the pixel and controlled by a pixel signal to switch an output voltage on the pixel between a high voltage and a low voltage;
• a calibration device coupled between the output stage and the pixel, wherein an input end of the calibration device controlled by a bias voltage to adjust the equivalent resistance of the calibration device for calibrating the brightness of the pixel;
• a stabilizing device coupled to the input end of the calibration device for stabilizing the voltage on the input end of the calibration device to be at the level of the bias voltage after a variation;
• and
• an accelerating device coupled between the stabilizing device and a voltage source for generating the bias voltage and accelerating the speed stabilizing the voltage on the input end of the calibration device to be at the level of the bias voltage.
