PIXEL UNIT, ARRAY SUBSTRATE, DISPLAY PANEL, AND DISPLAY APPARATUS
Document Type and Number:
WIPO Patent Application WO/2021/027897
Kind Code:
A1
Abstract:
A pixel unit, comprising a pixel circuit, a first sensing line (SENL1), and a second sensing line (SENL2); the pixel circuit is electrically connected to a light-emitting element (130), and the pixel circuit comprises a drive sub-circuit (111), the drive sub-circuit (111) being configured to drive the light-emitting element (130) electrically connected to the pixel circuit to emit light; the drive sub-circuit (111) has a control terminal, a first terminal, and a second terminal, the first terminal of the drive sub-circuit (111) being configured to be electrically connected to a first power source terminal (VDD) in order to receive a first power source voltage provided by the first power source terminal (VDD), and the first terminal of the drive sub-circuit (111) also being configured to be electrically connected to the first sensing line (SENL1); the second terminal of the drive sub-circuit is configured to be electrically connected to the light-emitting element (130); and the control terminal of the drive sub-circuit (111) is configured to be electrically connected to the second sensing line (SENL2). The first sensing line (SENL1) is configured to sense the voltage of the first terminal of the drive sub-circuit (111); and the second sensing line (SENL2) is configured to sense the voltage of the control terminal of the drive sub-circuit (111).
