Abstract
(EN)
Provided are a touch screen and a display device. The touch screen comprises thin film transistors and touch electrodes provided at a substrate. The substrate comprises signal channels and control channels. The signal channels are used to send or receive capacitance signals associated with the touch electrodes at different times. The control channels are used to control turning on or off of the thin film transistors. Sources of at least two thin film transistors are connected to a signal channel by means of a signal line. Gates of at least two thin film transistors are connected to a control channel by means of a control line. One touch electrode is connected to a drain of one thin film transistor.

L'invention concerne un écran tactile et un dispositif d'affichage. L'écran tactile comprend des transistors en couches minces et des électrodes tactiles disposées sur un substrat. Le substrat comprend des canaux de signal et des canaux de commande. Les canaux de signal sont utilisés pour envoyer ou recevoir des signaux de capacité associés aux électrodes tactiles à différents moments. Les canaux de commande sont utilisés pour commander la mise en marche ou l'arrêt des transistors en couches minces. Des sources d'au moins deux transistors à couches minces sont connectées à un canal de signal au moyen d'une ligne de signal. Des grilles d'au moins deux transistors à couches minces sont reliées à un canal de commande au moyen d'une ligne de commande. Une électrode tactile est connectée à un drain d'un transistor à couches minces.
