Abstract
(EN)
A driving method, a driving circuit, and a touch display device. The driving method comprises: providing a gate drive signal for gate lines (S401); providing a pixel voltage for data lines (S402); and providing a common electrode drive signal for a common electrode (130), wherein pixel driving is performed on the basis of the gate drive signal, the pixel voltage, and the common electrode drive signal, and performing touch detection on the basis of the common electrode drive signal (S403). The driving method achieves the effect of performing pixel display and touch detection simultaneously, and solves the problem that the display of a touch display device is affected in a touch detection stage.

La présente invention concerne un procédé d'attaque, un circuit d'attaque et un dispositif d’affichage tactile. Le procédé d'attaque comprend les étapes consistant à : fournir un signal d'attaque de grille pour des lignes de grille (S401) ; fournir une tension de pixel pour des lignes de données (S402 ); et fournir un signal d'attaque d'électrode commune pour une électrode commune (130), la commande de pixel étant effectuée sur la base du signal d'attaque de grille, de la tension de pixel et du signal d'attaque d'électrode commune et réaliser une détection tactile sur la base du signal d'attaque d'électrode commune (S403). Le procédé de commande permet de réaliser simultanément un affichage de pixels et une détection tactile et résout le problème selon lequel l'affichage d'un dispositif d'affichage tactile est affecté dans une étape de détection tactile.
