Title
(EN) PIXEL STRUCTURE OF DISPLAY
(FR) STRUCTURE DE PIXEL DE DISPOSITIF D'AFFICHAGE
(ZH) 显示器的像素结构
Abstract
(EN)
A pixel structure (1) of a display, comprising: a first pixel area (A); and a second pixel area (B) adjacent thereto. The first pixel area (A) has a first residual direct current electric field. The second pixel area (B) has a second residual direct current electric field. The electric field direction of the first residual direct current electric field is opposite to that of the second residual direct current electric field. By means of the alternate design of the structure of electrodes, residual ions gathered between an insulating layer and an electrode are reduced or eliminated so as to reduce or eliminate the afterimage phenomenon.
(FR)
Une structure de pixel (1) d'un dispositif d'affichage comprend : une première zone de pixel (A); et une seconde zone de pixel (B) adjacente à celle-ci. La première zone de pixel (A) a un premier champ électrique de courant continu résiduel. La seconde zone de pixel (B) a un second champ électrique de courant continu résiduel. La direction du champ électrique du premier champ électrique à courant continu résiduel est opposée à celle du second champ électrique à courant continu résiduel. Au moyen de la conception alternée de la structure d'électrodes, des ions résiduels collectés entre une couche isolante et une électrode sont réduits ou éliminés de façon à réduire ou éliminer le phénomène d'image rémanente.
