Title:
PIXEL CIRCUIT, DRIVING METHOD THEREFOR, AND DISPLAY DEVICE
Document Type and Number:
WIPO Patent Application WO/2018/210211
Kind Code:
A1
Abstract:
A pixel circuit, a driving method therefor, and a display device. A driving subcircuit (10) of the pixel circuit is connected respectively to a drive signal end (G1), to a data signal end (DATA), and to a driver node (C) and is configured, under the control of a drive signal from the drive signal end (G1), to provide the driver node (C) with a data signal coming from the data signal end. A holding subcircuit (20) of the pixel circuit is connected respectively to the driver node (C), to a first switch signal end (S1), to a first power signal end (VDD), and to a second power signal end (VSS) and is configured, under the control of a first switch signal from the first switch signal end (S1), to acquire the potential of the driver node (C) and, under the control of a first power signal from the first power signal end (VDD) and a second power signal from the second power signal end (VSS), to keep the potential of the driver node (C) from changing. A light-emitting subcircuit (30) of the pixel circuit is connected to the driver node (C) and is configured to be driven by the driver node (C) to emit a light.
