Title:
PIXEL CIRCUIT AND DRIVING METHOD, AND DISPLAY DEVICE
Document Type and Number:
WIPO Patent Application WO/2019/085502
Kind Code:
A1
Abstract:
Disclosed are a pixel circuit and a driving method, and a display device, the pixel circuit comprising: a first thin-film transistor, a second thin-film transistor, a third thin-film transistor, a fourth thin-film transistor, a fifth thin-film transistor, a sixth thin-film transistor, a seventh thin-film transistor, an eighth thin-film transistor, a ninth thin-film transistor, a first capacitance, a second capacitance, and a light-emitting diode (LED). In embodiments of the present application, compensation voltage provided by a compensation voltage signal line is capable, during the light-emitting stage of the pixel circuit, of providing compensation for the supply voltage of same, so that current flowing through the LED is determined by the compensation voltage and the power supply voltage together, thereby reducing to a certain extent the impact of drop-offs in supply voltage on current flowing through the LED, and thus also reducing the impact of drop-offs in supply voltage on the evenness of display of the display device.
