Abstract
The present disclosure provides a pixel circuit, a driving method thereof, a display module, a driving method thereof and a display device. The pixel circuit includes a touch pixel driving sub-circuit. The touch pixel driving sub-circuit includes a pixel driving circuit, a control circuit and a photosensitive touch circuit. The photosensitive touch circuit outputs a touch sensing current signal. The pixel driving circuit is configured to extract a threshold voltage signal of a driving transistor, and output the threshold voltage signal. The control circuit is configured to control whether or not a touch sensing current signal output end is to be electrically connected to a touch display signal line under the control of a touch reading control end, and control whether or not a compensation signal output end is to be electrically connected to the touch display signal line under the control of a display compensation control end.
