Abstract

L'invention concerne un afficheur à panneau plat à commande tactile actif. Un système de commande tactile actif séparé est prévu sur un verre de substrat d'un afficheur actif. Pendant un processus de fabrication existant d'un écran d'affichage à panneau plat actif, un système de commande tactile actif est prévu sur un verre de substrat de l'écran d'affichage à panneau plat actif par l'utilisation des techniques de fabrication existantes de l'écran d'affichage à panneau plat actif. De cette manière, un système d'affichage actif et un système de commande tactile actif qui sont séparés l'un de l'autre et qui ont des fonctions indépendantes sont prévus sur l'écran d'affichage à panneau plat actif en même temps, de sorte qu'un écran d'affichage actif et un écran à commande tactile actif sont combinés. Par conséquent, l'afficheur à panneau plat à commande tactile devient plus léger et plus mince. En outre, par l'introduction de composants actifs dans l'écran à commande tactile actif, les unités d'électrodes de détection sur l'écran fonctionnent en totale indépendance, de sorte que la détermination d'une commande tactile multipoint est simplifiée, et l'opération de commande tactile multipoint devient facile et commode.
