Title
(EN) TOUCH DISPLAY DEVICE AND DRIVING METHOD THEREFOR
(FR) DISPOSITIF D'AFFICHAGE TACTILE ET PROCÉDÉ DE COMMANDE ASSOCIÉ

Abstract
(EN)
A touch display device and a driving method therefor. The touch display device comprises a display panel (10), a touch layer (20), and a control module (30); the display panel (10) comprises multiple data lines (11) arranged at intervals; the touch layer (20) comprises a sensing electrode layer (21); the control module (30) is electrically connected to the sensing electrode layer (21) by means of a detection signal line (40); during driving, a voltage on the sensing electrode layer (21) is detected by the control module (30) by means of the detection signal line (40); when the control module (30) detects occurrence of a ripple to the waveform of the voltage on the sensing electrode layer (21), the control module (30) reverses the polarity of a data voltage input from the multiple data lines (11) of the display panel (10), thereby effectively eliminating an abnormal ripple of a sensing signal on the sensing electrode layer (21) and reliably achieving a touch function.

La présente invention concerne un dispositif d’affichage tactile et un procédé de commande associé. Le dispositif d'affichage tactile comprend un panneau d'affichage (10), une couche tactile (20) et un module de commande (30) ; le panneau d'affichage (10) comprend de multiples lignes de données (11) agencées à des intervalles ; la couche tactile (20) comprend une couche d'électrode de détection (21) ; le module de commande (30) est connecté électriquement à la couche d'électrode de détection (21) au moyen d'une ligne de signal de détection (40) ; pendant la commande, une tension sur la couche d'électrode de détection (21) est détectée par le module de commande (30) au moyen de la ligne de signal de détection (40) ; lorsque le module de commande (30) détecte l'apparition d'une ondulation sur la forme d'onde de la tension sur la couche d'électrode de détection (21), le module de commande (30) inverse la polarité d'une entrée de tension de données à partir des multiples lignes de données (11) du panneau d'affichage (10), ce qui permet d'éliminer efficacement une ondulation anormale d'un signal de détection sur la couche d'électrode de détection (21) et d'obtenir de manière fiable une fonction tactile.
