Title:
HYBRID COMPENSATION PIXEL CIRCUIT, CONTROL METHOD, AND DISPLAY DEVICE
Document Type and Number:
WIPO Patent Application WO/2021/103106
Kind Code:
A1
Abstract:
A hybrid compensation pixel circuit, a control method, and a display device. The hybrid compensation pixel circuit comprises an internal compensation circuit (1) and an external compensation circuit (2). The internal compensation circuit (1) comprises a first thin film transistor (T1), a second thin film transistor (T2), a third thin film transistor (T3), and a fourth thin film transistor (T4); the external compensation circuit (2) comprises a fifth thin film transistor (T5). By optimizing pixel circuit architecture, there is no NTFT with a positive long-term relative voltage, thereby improving the stability of a circuit, simplifying a compensation process, and improving accuracy of compensation.
