Title:
PIXEL CIRCUIT AND DRIVING METHOD THEREFOR, AND DISPLAY DEVICE
Document Type and Number:
WIPO Patent Application WO/2020/048281
Kind Code:
A1
Abstract:
A pixel circuit and a driving method therefor, and a display device. The pixel circuit comprises an input subcircuit (21), a light-emission control subcircuit (22) and an organic light-emitting transistor (OLET, 1). The input subcircuit (21) is connected to a gate line (Gate), a data line (Data) and the light-emission control subcircuit (22), and is used to write a data signal (VData) provided by the data line (Data) to the light-emission control subcircuit (22) under control of a gate scanning signal (VGate) provided at the gate line (Gate). The light-emission control subcircuit (22) is connected to a control electrode of the organic light-emitting transistor (OLET, 1), and is used to control, according to the data signal (VData) written thereto, a voltage at the control electrode of the organic light-emitting transistor (OLET, 1) so as to drive the organic light-emitting transistor (OLET, 1) to emit light. The invention enables active matrix driving to be performed on an organic light-emitting transistor (OLET, 1) applied in a display device.
