Title:
COMPENSATION CIRCUIT, CONTROL CHIP AND DISPLAY APPARATUS
Document Type and Number:
WIPO Patent Application WO/2023/236501
Kind Code:
A1
Abstract:
A compensation circuit (2), a control chip and a display apparatus. The compensation circuit (2) is applied to a driving circuit (1), wherein the driving circuit (1) comprises a first thin film transistor (T1), a second thin film transistor (T2), an organic light-emitting diode (OLED) and a capacitor (C). The compensation circuit (2) comprises a third thin film transistor (T3) and a detection module (201), wherein a control electrode (T3a) of the third thin film transistor (T3) is used for connecting to a second electrode (T2c) of the second thin film transistor (T2); a first electrode (T3b) of the third thin film transistor (T3) is used for connecting to a control electrode (T2a) of the second thin film transistor (T2); the detection module (201) is connected to a second electrode (T3c) of the third thin film transistor (T3), a scanning line (Scan) and a data line (Data); and the detection module (201) is used for being turned off and turned on upon receiving two adjacent voltage signals which are output by the second electrode (T3c) of the third thin film transistor (T3). The compensation circuit (2) has a simple line connection, and solves the problem of the light-emission rate of an OLED panel being relatively low due to threshold voltage drifting of the OLED panel, thereby guaranteeing the light-emission rate of the OLED panel.
