Title:
GATE DRIVER ON ARRAY CIRCUIT, THIN-FILM TRANSISTOR, AND DISPLAY APPARATUS
Document Type and Number:
WIPO Patent Application WO/2020/062230
Kind Code:
A1
Abstract:
Provided are a thin-film transistor (T1), a gate driver on array circuit (1), and a display apparatus (100) having the gate driver on array circuit (1), wherein the gate driver on array circuit (1) comprises several thin-film transistors (T1); a back gate (10) is added to the position of a gate electrode of at least one thin-film transistor (T1); and the back gate (10) of each thin-film transistor (T1) with the back plate (10) added is used for accessing a compensation voltage to compensate a threshold value voltage shift of the thin-film transistor (T1). By means of adding the structure of the back gate (10) to the position of the gate electrode of at least one thin-film transistor (T1) in the gate driver on array circuit (1), and acquiring a compensation voltage by means of the back gate (10), the voltage drift phenomena of the thin-film transistor (T1) can be effectively eliminated from the source, and the normal working of the gate driver on array circuit (1) is ensured.
