Abstract
A gamma voltage regulation circuit set in a driver chip of a display panel, includes: an input circuit configured to determine a measured value of a power supply voltage of a power supply; a computing circuit configured to compute a variation value between the measured value and a reference value of the power supply voltage, an adjustment circuit configured to adjust a dynamic value of a reference voltage of a grayscale voltage generated by gamma correction through the variation value; and a third output circuit configured to output the grayscale voltage based on the dynamic value.
