L'invention porte sur un dispositif d'affichage à cristaux liquides équipé d'un panneau d'affichage qui possède un capteur optique incorporé dans un pixel. Le dispositif d'affichage à cristaux liquides comprend un réseau de capteurs bidimensionnel dans lequel des circuits de capteurs optiques sont disposés de manière bidimensionnelle. Chacun des circuits de capteur optique est formé par une photodiode (17), un amplificateur de sortie et un condensateur élévateur de tension NetA. L'amplificateur de sortie possède une électrode grille reliée à l'électrode de cathode (NetA) de la photodiode (18), une électrode source reliée à un câble d'alimentation électrique (Vsm) et une électrode déversoir reliée à un câble de sortie de capteur optique (Vom). Le condensateur élévateur de tension NetA possède une électrode reliée au NetA, l'autre électrode étant reliée électriquement à un fil de commande (Vrwn) pour distribuer un signal de commande au condensateur élévateur de tension NetA. Un fil de capacité auxiliaire (Csn) pour maintenir le potentiel de pixel sert également de fil de commande (Vrwn). Le dispositif d'affichage à cristaux liquides qui possède le réseau de capteurs bidimensionnel peut supprimer l'abaissement de l'ouverture numérique du pixel ou augmenter la région de bord de la périphérie d'affichage. La présente invention est utilisée, de préférence, dans un dispositif électronique ayant un panneau tactile.
