Embodiment Construction
[0031] In the organic light emitting diode pixel circuit and the display device provided by the embodiments of the present invention, since the driving signal generation module can read and store the threshold voltage of the driving transistor in the threshold voltage reading stage, and can receive the image data signal in the signal loading stage, and according to the threshold voltage reading stage The received display signal of the frame and the threshold voltage of the driving transistor stored in the threshold voltage reading stage generate a driving signal, which makes the driving signal related to the threshold voltage of the driving transistor. Therefore, the driving signal is used in the waiting stage and the light-emitting stage When the driving transistor is controlled to drive the OLED to emit light, the influence of the threshold voltage of the driving transistor on the drain current of the driving transistor will be offset by the existence of the threshold voltage ...
