Title
(EN) ACTIVE PEN, TOUCH INPUT SYSTEM, AND DRIVING METHOD
(FR) STYLO ACTIF, SYSTÈME D'ENTRÉE TACTILE ET PROCÉDÉ D'ATTAQUE

Abstract
(EN)
An active pen (10) for a touch display screen, a touch input system, and a driving method. The active pen (10) comprises: a signal receiving device (110), a processor (120) in signal connection with the signal receiving device (110), and a signal transmitting device (130) in signal connection with the processor (120). The signal receiving device (110) is used to receive a first coupling voltage between the active pen (10) and a touch display screen. The processor (120) is used to process the first coupling voltage so as to obtain a second coupling voltage. The second coupling voltage and the first coupling voltage have opposite polarities. The signal transmitting device (130) is used to emit the second coupling voltage to the touch display screen. The active pen (10) can increase an amount of valid signals obtained when a touch display screen performs touch detection, thereby increasing sensitivity of touch detection.

L'invention concerne un stylo actif (10) destiné à un écran d'affichage tactile, un système d'entrée tactile et un procédé d'attaque. Le stylo actif (10) comprend : un dispositif de réception de signal (110), un processeur (120) en connexion de signal avec le dispositif de réception de signal (110), et un dispositif d'émission de signal (130) en connexion de signal avec le processeur (120). Le dispositif de réception de signal (110) sert à recevoir une première tension de couplage entre le stylo actif (10) et un écran d'affichage tactile. Le processeur (120) sert à traiter la première tension de couplage de façon à obtenir une seconde tension de couplage. La seconde tension de couplage et la première tension de couplage ont des polarités contraires. Le dispositif d'émission de signal (130) sert à délivrer la seconde tension de couplage à l'écran d'affichage tactile. Le stylo actif (10) peut augmenter une quantité de signaux valides obtenus lorsqu'un écran d'affichage tactile effectue une détection tactile, ce qui permet d'augmenter la sensibilité de détection tactile.
