Title:
PIXEL DRIVING CIRCUIT AND DRIVING METHOD THEREOF, AND DISPLAY PANEL
Document Type and Number:
WIPO Patent Application WO/2020/151007
Kind Code:
A1
Abstract:
A pixel driving circuit and a diving method thereof, and a display panel. The pixel driving circuit (10) comprises a current control circuit (100) and a time control circuit (200). The current control circuit (100) is configured to receive a display data signal and control, according to the display data signal, the current level of a drive current flowing through the current control circuit (100). The time control circuit (200) is configured to receive the drive current, receive a time data signal, a first light emitting control signal, and a second light emitting control signal, and control, according to the time data signal, the first light emitting control signal, and the second light emitting control signal, the duration when the drive current passes through. Binary unit duration control is implemented by the pixel driving circuit (10) under multiple times of scanning, and flexibility of duration control is improved, so that compensation to grayscale brightness is implemented, and a display effect of the display panel is improved.
