Title:
PIXEL CIRCUIT, DISPLAY PANEL, AND DISPLAY DEVICE
Document Type and Number:
WIPO Patent Application WO/2020/253494
Kind Code:
A1
Abstract:
A pixel circuit (10), a display panel, and a display device. The pixel circuit (10) comprises a first switching transistor (T1), a second switching transistor (T2), a driving transistor (T3), a capacitor (C), a light emitting diode (L), a first gate line (11) and a first data line (12) extending along a first direction, a second gate line (21) and a second data line (22) extending along a second direction, and a power cord (3), the first direction and the second direction crossing each other; the gate of the first switching transistor (T1) is coupled to the first gate line (11), and the source is coupled to the first data line (12); the gate of the second switching transistor (T2) is coupled to the second gate line (21), and the source is coupled to the second data line (22); the gate of the driving transistor (T3) is simultaneously coupled to the drain of the first switching transistor (T1) and the drain of the second switching transistor (T2), the source of the driving transistor (T3) is coupled to the power cord (3), and the drain is coupled to the light emitting diode (L); one end of the capacitor (C) is coupled to the gate of the driving transistor (T3), and the other end is coupled to the power cord (3).
