Abstract:
A display driving unit circuit, a driving method, a display driving circuit and a display device are provided. The display driving unit circuit includes a pixel driving circuit and a light-emission control signal generation circuit. The light-emission control signal generation circuit is coupled to the pixel driving circuit. The pixel driving circuit is to drive a pixel to emit light. The light-emission control signal generation circuit is to supply a display light-emission control signal to the pixel driving circuit at a display stage to enable the pixel in a displaying mode and supply a fingerprint detection light-emission control signal to the pixel driving circuit at a fingerprint detection stage to enable the pixel in a fingerprint detection light-emission mode at the fingerprint detection stage. The display stage and the fingerprint detection stage are different time periods.
