Title:
PIXEL COMPENSATION CIRCUIT AND DRIVING METHOD THEREFOR, AND DISPLAY DEVICE
Document Type and Number:
WIPO Patent Application WO/2018/157442
Kind Code:
A1
Abstract:
A pixel compensation circuit (10) and a driving method therefor, and a display device (40). The pixel compensation circuit (10) comprises: a light-emitting element (11); 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) and a first end connected to a data signal (Data); a second switching transistor (T2) with a control end connected to a control signal (EM) and a first end connected to a second end of the driving switching transistor (T); a third switching transistor (T3) with a control end connected to a second scan signal (Scan2); and a storage capacitor (Cst) with a first end connected to a control end of the driving switching transistor (T) and a second end connected to a second end of the second switching transistor (T2). 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.
