Title:
PIXEL CIRCUIT AND DRIVING METHOD THEREFOR, ARRAY SUBSTRATE, AND DISPLAY PANEL
Document Type and Number:
WIPO Patent Application WO/2019/242369
Kind Code:
A1
Abstract:
Provided are a pixel circuit and a driving method therefor, an array substrate, and a display panel. The pixel circuit comprises a data write circuit, an initialization circuit, a sensing circuit, a first capacitor, a second capacitor, a driving transistor, and a data signal provision circuit. The data write circuit provides a data signal from a data line to a first node according to a first control signal. The initialization circuit provides an initialization signal to a sensing line according to a second control signal. The sensing circuit couples a second node to the sensing line according to the first control signal such that the voltage of the second node and the voltage on the sensing line are equal. The first capacitor stores a voltage difference between the first node and the second node. The second capacitor stores the voltage on the sensing line. The driving transistor provides a driving current. The data signal provision circuit reads the voltage on the sensing line according to a third control signal, determines a threshold voltage of the driving transistor according to the read voltage, and corrects an original data signal from a data signal end according to the threshold voltage to provide same to the data line.
