Title:

PIXEL DRIVER CIRCUIT, DRIVE METHOD THEREFOR, AND DISPLAY DEVICE

Document Type and Number:

WIPO Patent Application WO/2018/049800

Kind Code:

A1

Abstract:

A pixel driver circuit, a drive method therefor, and a display device. In the pixel driver circuit, a control end (D3) of a driving unit (D) is connected to a first end (C1) of a storage capacitor (Cst), a first signal end (101) of a first switch unit (S1), a first signal end (201) of a second switch unit (S2), and a control end (303) of a third switch unit (S3). A control end (103) of the first switch unit (S1) is used for inputting a reset signal (Reset). A second signal end (102) of the first switch unit (S1) is connected to an initialization voltage (Vint). A control end (203) of the second switch unit (S2) is used for inputting a scan signal (Gate). A second signal end (202) of the second switch unit (S2) is connected to a first signal end (301) of the third switch unit (S3). A second signal end (302) of the third switch unit (S3) is used for inputting a data signal (Data). A control end (403) of a fourth switch unit (S4) is used for inputting a light emitting signal (EM).
