Abstract
(EN)
A display device, which is applied in a mobile terminal comprising a camera (35), and comprises an upper polarizer sheet (33) and a display panel (34). The upper polarizer sheet (33) is adhered onto the display panel (34), and the region of the upper polarizer sheet (33) facing the camera (35) is a high light-transmissive region (33a). In the manufacturing process of the display device, the upper polarizer sheet (33) comprising the high light-transmissive region (33a) is directly used without punching a hole for the upper polarizer sheet (33) and then filling, which avoids risks generated by the operation such as the bubble and glue overflow, and simplifies the process while ensuring the high resolution camera function of the camera (35).
(FR)
L'invention concerne un dispositif d'affichage, qui est appliqué dans un terminal mobile comprenant une caméra (35), et comprend une feuille de polariseur supérieure (33) et un écran d'affichage (34). La feuille de polariseur supérieure (33) est collée sur l'écran d'affichage (34), et la région de la feuille de polariseur supérieure (33) faisant face à la caméra (35) est une région de transmission de lumière élevée (33a). Dans le processus de fabrication du dispositif d'affichage, la feuille de polariseur supérieure (33) comprenant la région de transmission de lumière élevée (33a) est directement utilisée sans percer un trou pour la feuille de polariseur supérieure (33) et ensuite le remplissage, ce qui évite les risques générés par l'opération telle que la bulle et le trop-plein de colle, et simplifie le processus tout en garantissant la fonction de caméra à haute résolution de la caméra (35).

一种显示装置,应用于包括摄像头(35)的移动终端,显示装置包括上偏光片(33)及显示面板(34),其中上偏光片(33)粘接于显示面板(34)上,且上偏光片(33)与摄像头(35)相对的区域为高透光区域(33a)。在显示装置的制造过程中,直接使用具有高透光区(33a)的上偏光片(33),从而无需对上偏光片(33)进行挖孔后再填充的操作,避免了此操作产生的气泡、溢胶等的风险,简化了制程工艺,同时保证了摄像头(35)的高清摄像功能。
