Abstract

La présente invention concerne un procédé de compensation tactile, appliqué à un écran d'affichage tactile flexible, qui comprend les étapes consistant : à générer un signal de détection correspondant au moyen de la détection de paramètres électriques de chaque dispositif d'affichage électroluminescent (11) d'un dispositif d'affichage tactile flexible (100) respectivement au moyen de plusieurs unités de détection (12) dans un écran d'affichage tactile flexible ; à déterminer, en fonction du signal de détection généré par chaque unité de détection (12), si un changement dans les paramètres électriques de chaque dispositif d'affichage électroluminescent (11) se produit, et à déterminer si la quantité de changement satisfait à une condition prédéterminée ; à déterminer au moins un point de pixel cible (P1) correspondant à au moins un dispositif d'affichage électroluminescent (11) dont la quantité de changement dans les paramètres électriques satisfait à la condition prédéterminée, et à déterminer, en fonction dudit point de pixel cible (P1), au moins une unité tactile cible (21) qui doit être compensée ; et à effectuer une compensation tactile sur ladite unité tactile cible (21). La présente invention concerne également un dispositif d'affichage tactile flexible (100). Le dispositif d'affichage tactile flexible (100) et le procédé de compensation tactile peuvent détecter efficacement une zone de flexion et effectuer une compensation tactile.
