PIXEL CIRCUIT AND DISPLAY DEVICE

摘要

A pixel circuit and a display device. The pixel circuit comprises: a pixel compensation module(100), a light-emitting module (200) and a touch control detection module (300), said pixel compensation module(100) being connected to first to fourth scanning signal lines (Scan[1], Scan[2], Scan[3], Em), to a first operating voltage (Vdd), to a data voltage(Vdata) and to the light-emitting module (200) respectively, and being used for controlling the light-emitting module (200) to conduct a light-emitting display according to the input of the scanning signal lines; the touch control detection module (300) comprises a detection submodule (310) and an output submodule (320). The pixel compensation module (100) and the touch control detection module (300) are integrated into the pixel circuit, and the pixel compensation module (100) and the touch control detection module (300) are able to share a data voltage (Vdata) and the scanning signal lines, so that the number of signal lines is reduced, thereby greatly reducing the size of pixel spacing and reducing IC costs, and thus obtaining a higher pixel density.
