Abstract
The disclosure discloses a voltage compensation method, a compensation circuit, and a display device of OLED. The OLED voltage compensation method includes detecting and acquiring a brightness value of each pixel of the OLED display panel; converting the brightness value into a voltage code according to a Gamma curve; and acquiring compensation data according to the driving voltage code, and compensating the driving voltage code according to the compensation data to drive the OLED display panel to display according to the compensated driving voltage code. In this way, the accuracy of the OLED voltage compensation can be improved, and the display effect of the OLED display panel can be improved.
