Title:
OLED PIXEL DRIVE CIRCUIT
Document Type and Number:
WIPO Patent Application WO/2019/227849
Kind Code:
A1
Abstract:
The present invention provides an OLED pixel drive circuit. The OLED pixel drive circuit comprises a sub-pixel drive module and a drive compensation module electrically connected with the sub-pixel drive module, wherein the drive compensation module can not only detect a threshold voltage of a drive thin film transistor, but also detect a reverse capacitance of an organic light-emitting diode, furthermore, the drive compensation module can also drive the organic light-emitting diode to emit light, and the number of data lines is relatively small.
