Abstract
The disclosure discloses an AMOLED driving circuit and a display device. The driving circuit includes a pixel circuit, a digital driving circuit, and a detection circuit. The pixel circuit includes a data cable and a first switch element. The data cable and the first switch element are coupled. The digital driving circuit is coupled with the data cable, configured to provide a digital voltage signal to the pixel circuit by the data cable. The detection circuit is coupled with the data cable, configured to receive and output the current fed back from the data cable and flowing through the first switch element. The current is configured to compensate a threshold voltage of the first switch element. According to the manner above, embodiments provided by the disclosure can enhance the display effect of the AMOLED.
