Abstract
(EN)
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.
(FR)
L'invention concerne un transistor à couches minces (T1), un circuit d'attaque de grille sur circuit en réseau (1) et un appareil d'affichage (100) comprenant le circuit d'attaque de grille sur circuit en réseau (1), le circuit d'attaque de grille sur circuit en réseau (1) comprenant plusieurs transistors à couches minces (T1) ; une grille arrière (10) étant ajoutée à la position d'une électrode de grille d'au moins un transistor à couches minces (T1) ; et la grille arrière (10) de chaque transistor à couches minces (T1) comprenant la plaque arrière (10) ajoutée étant utilisée pour accéder à une tension de compensation permettant de compenser un décalage de tension de valeur de seuil du transistor à couches minces (T1). Grâce à l'ajout de la structure de la grille arrière (10) à la position de l'électrode de grille d'au moins un transistor à couches minces (T1) dans le circuit d'attaque de grille sur circuit en réseau (1), et à l'acquisition d'une tension de compensation au moyen de la grille arrière (10), les phénomènes de dérive de tension du transistor à couches minces (T1) peuvent être efficacement éliminés de la source, et le fonctionnement normal du circuit d'attaque de grille sur circuit en réseau (1) est assuré.
(ZH)
一种薄膜晶体管(T1)、阵列基板栅极驱动电路(1)及具有阵列基板栅极驱动电路(1)的显示装置(100)。阵列基板栅极驱动电路(1)包括若干薄膜晶体管(T1),至少一个薄膜晶体管(T1)的栅极的位置增加了背栅(10),每一增加了背栅(10)的薄膜晶体管(T1)的背栅(10)用于接入补偿电压,以补偿薄膜晶体管(T1)的阈值电压漂移。通过在阵列基板栅极驱动电路(1)中的至少一个薄膜晶体管(T1)的栅极的位置增加背栅(10)这一结构,并通过背栅(10)获得补偿电压,可有效的从源头上消除薄膜晶体管(T1)的电压漂移现象,保证了阵列基板栅极驱动电路(1)的正常工作。
