PIXEL CIRCUIT AND DISPLAY DEVICE

摘要

Disclosed are a pixel circuit and a display apparatus. The pixel circuit comprises a pixel compensation module (100), a light emitting module (200) and a touch detection module (300); the pixel compensation module (100) is connected to a first to a fourth scan signal lines (Scan[1], Scan[2], Scan[3], Em), a first operation voltage (Vdd), a data voltage (Vdata) and the light emitting module (200) respectively, and is configured to control the light emitting module (200) to emit light for display in accordance with inputs from the scan signal lines; the touch detection module (300) comprises a detection sub module (310) and an output sub module (320). The pixel compensation module (100) and the touch detection module (200) are integrated into the pixel circuit, and the pixel compensation module (100) and the touch detection module (200) share the data voltage (Vdata) and the scan signal line in common. In this way, the number of signal lines is decreased, thereby the pitch of pixels is largely decreased and IC cost is reduced, achieving a higher pixel density.
