US Patent 9720535 Pixel circuit and display apparatus

A pixel circuit and a display apparatus, the pixel circuit comprises a pixel compensation module, a light emitting module and a touch detection module. By integrating the pixel compensation module and the touch detection module into the pixel circuit, and making the pixel compensation module and the touch detection module share data voltage lines and scan signal lines, a number of signal lines can be reduced, so that a size of space between pixels can be decreased greatly and a cost of an IC is also reduced, which can achieve a higher pixel density.
