Abstract: The present application relates to a light emission control and scan driver and a display device having the drivers. A light emission control and scan driver includes a plurality of driver stages for outputting light emission control signals and scan signals, each of which including: a light emission control driving unit for providing control signals to the scan units and a scan driving unit. Control signals may be light emission control signals. The light emission control driving unit has a first input signal terminal, a first clock terminal, a second clock terminal and a light emission control output terminal, and outputs light emission control signals at the light emission control output terminal based on input signals input at the first input signal terminal, light emission timing control signals input at the first clock terminal and inverted light emission timing control signals input at the second clock terminal.

Abstract: The present disclosure provides a pixel driving circuit and a display device, the pixel driving circuit includes: a control unit; a capacitor; a first transistor; a second transistor; a third transistor and a fourth transistor. The present disclosure can effectively compensate the variation of the threshold voltage of the drive thin film transistor by controlling the thin film transistors, thus prevent nonuniform brightness of a screen due to nonuniform current, and extend lifespan of the screen.
