Abstract
The present disclosure proposes an OLED pixel compensation circuit and an OLED pixel compensation method. The OLED pixel compensation circuit includes an OLED, a driving transistor, a first TFT, a second TFT, a third TFT, a fourth TFT, a first capacitor, and a second capacitor. The present disclosure adopts 5T2C structure and the driving transistor is a double gate TFT to compensate the variance of the threshold voltage such that the luminance evenness is raised and the lifetime of the product is extended.
