Title:
DISPLAY PANEL AND VOLTAGE REGULATION METHOD THEREFOR, AND DISPLAY APPARATUS
Document Type and Number:
WIPO Patent Application WO/2019/184407
Kind Code:
A1
Abstract:
Provided are a display panel and a voltage regulation method therefor, and a display apparatus. The display panel comprises: at least two reference sub-pixels 11; a voltage compensation unit 12 respectively coupled to each of the reference sub-pixels 11; and a power source management unit 13 coupled to the voltage compensation unit 12, wherein the voltage compensation unit 12 is configured to collect, when data voltages received by the at least two reference sub-pixels 11 are the same, an effective value of a pixel voltage of each of the reference sub-pixels, and generate, according to a compensation target of enabling the collected effective value of the pixel voltage of each of the reference sub-pixels to be consistent, a compensation signal of a gate-off voltage VGL; and the power source management unit is configured to regulate a voltage value of the gate-off voltage VGL according to the compensation signal of the gate-off voltage VGL.
