Abstract

La présente invention concerne un écran tactile et un dispositif d'affichage. L'écran tactile comprend une plaque d'électrode tactile et des électrodes de pixel agencées en une matrice. La plaque d'électrode tactile est disposée dans une direction de projection positive des électrodes de pixel par rapport à une surface d'affichage de l'écran tactile. Une matrice noire est également disposée dans la direction de projection positive des électrodes de pixel par rapport à la surface d'affichage de l'écran tactile. La matrice noire est agencée de façon à correspondre à une zone entre deux électrodes de pixel quelconques adjacentes, la plaque d'électrode tactile est située dans une direction de projection positive de la matrice noire par rapport à la surface d'affichage de l'écran tactile et la matrice noire protège complètement les bords de la plaque d'électrode tactile. Étant donné que la matrice noire protège complètement les bords de la plaque d'électrode tactile dans l'écran tactile, la plaque d'électrode tactile d'une configuration quelconque est invisible à l'œil humain lorsqu'elle est affichée, de sorte que la qualité des images affichées sur l'écran tactile soit assurée, le problème de fuite de la plaque d'électrode tactile dans l'écran tactile soit résolu et que l'effet d'affichage de l'écran tactile soit amélioré.
