Title:

PIXEL CIRCUIT, DISPLAY PANEL, DISPLAY DEVICE, AND DRIVING METHOD

Document Type and Number:

WIPO Patent Application WO/2018/028209

Kind Code:

A1

Abstract:

A pixel circuit, display panel, display device, and driving method, the pixel circuit (100) comprising: a light emitting circuit (110), comprising a plurality of light emitting subcircuits (111); a compensation driver circuit (120), comprising an output terminal (121) and a driving transistor, the plurality of light emitting subcircuits (111) being electrically connected to the output terminal (121), and the compensation driver circuit (120) being configured to receive a light-emitting data signal, to compensate for a threshold voltage of the driving transistor, and to drive any one of the light-emitting subcircuits (111) to emit light according to an output signal output by the output terminal. Said configuration reduces the number of compensation driver circuits and compresses the back board space occupied by the compensation driver circuit, thereby increasing resolution of the display panel.
