Abstract
The present disclosure provides a voltage compensation circuit and a voltage compensation method, a display driving circuit and a display device. The voltage compensation circuit includes: a voltage analyzing sub-circuit and a gamma voltage generating sub-circuit. The voltage analyzing sub-circuit is coupled to the display panel and configured to obtain pixel voltages of target pixels in the image to be detected; judge whether the display panel is abnormal according to the pixel voltages; generate a compensation control signal in response to that the display panel is abnormal. The gamma voltage generating sub-circuit is coupled to the voltage analyzing sub-circuit and is configured to compensate a gamma voltage corresponding to the image to be detected according to the compensation control signal so as to enable the pixel voltages of the target pixels to be consistent.
