Abstract

L'invention porte sur un dispositif d'excitation d'écran tactile capable d'éviter la fausse détection d'une position de contact et de détecter un contact avec une grande sensibilité. Le contrôleur d'écran tactile (40) est doté : d'une unité d'excitation d'écran tactile (41) servant à exciter un écran tactile (30) ; et d'une unité de blocage de balayage (43) destinée à bloquer l'excitation d'un écran à cristaux liquides (11), ladite unité d'excitation d'écran tactile (41) excitant ledit écran tactile (30) pendant que ladite unité de blocage de balayage (43) bloque l'excitation d'une ligne de signal de balayage.
