Title (EN) DISPLAY DEVICE AND ELECTRONIC DEVICE
(FR) DISPOSITIF D’AFFICHAGE ET DISPOSITIF ÉLECTRONIQUE
Abstract:
(EN) To provide a display device capable of performing image processing. Each pixel is provided with a memory circuit in which desired correction data is retained. The correction data is generated by calculation in an external device and written to each pixel. The correction data is added to image data by capacitive coupling and supplied to a display element. Thus, the display element can display a corrected image. Through the correction, image upconversion can be performed, or image quality decreased because of variations in pixel transistor characteristics can be corrected.
(FR) La présente invention a pour objet un dispositif d’affichage capable de réaliser un traitement d’images. Chaque pixel est doté d’un circuit mémoire qui conserve des données de correction souhaitée. Les données de correction sont générées par calcul dans un dispositif externe et écrites dans chaque pixel. Les données de correction sont ajoutées aux données d’image par couplage capacitif et fournies à un élément d’affichage. De cette façon, l’élément d’affichage peut afficher une image corrigée. La correction permet de réaliser une conversion ascendante d’image ou de corriger une qualité d’image dégradée en raison de variations des caractéristiques des transistors commandant les pixels.
