Title:
PIXEL DRIVE CIRCUIT AND ORGANIC LIGHT-EMITTING DIODE DISPLAY APPARATUS
Document Type and Number:
WIPO Patent Application WO/2019/090907
Kind Code:
A1
Abstract:
A pixel drive circuit and an organic light-emitting diode display apparatus. The pixel drive circuit comprises: a data write switch transistor (T1), a first reset switch transistor (T2), a second reset switch transistor (T3), a drive transistor (T4), an organic light-emitting diode (OLED), and a first storage capacitor (C1) and a second storage capacitor (C2), which can compensate for the drift of a threshold voltage (Vth) of the drive transistor (T4) to improve the display quality.
