Title:
PIXEL COMPENSATION CIRCUIT AND DRIVING METHOD THEREFOR, AND DISPLAY DEVICE
Document Type and Number:
WIPO Patent Application WO/2018/157443
Kind Code:
A1
Abstract:
A pixel compensation circuit (10) and a driving method therefor, and a display device (20). The pixel compensating circuit (10) comprises: a light-emitting element (11) with one end connected to a common voltage (VSS); a driving switching transistor (T) with a first end connected to a power voltage (VDD); a first switching transistor (T1) with a control end connected to a first scan signal (Scan); a second switching transistor (T2) with a control end connected to the first scan signal (Scan); a third switching transistor (T3) with a control end connected to the first scan signal (Scan); a fourth switching transistor (T4) with a control end connected to a second scan signal (Scan2); a fifth switching transistor (T5) with a control end connected to the first scan signal (Scan); and a storage capacitor (Cst) with a first end connected to a second end of the third switching transistor (T3) and a second end connected to a second end of the driving switching transistor (T). According to the pixel compensation circuit, impact of threshold voltage (Vth) of the driving switching transistor (T) on driving current (IOLED) passing through the light-emitting element (11) can be eliminated.
