Title
(EN) OLED DISPLAY PANEL AND METHOD FOR MANUFACTURING SAME
(FR) PANNEAU D'AFFICHAGE À DELO ET SON PROCÉDÉ DE FABRICATION
(ZH) OLED显示面板及其制作方法
Abstract
(EN)
Provided are an OLED display panel and a method for manufacturing same. By means of providing a light-transmitting hole in an OLED display panel and providing a baffle and a thin film encapsulation layer outside several sub-pixel areas around the light-transmitting hole, some light rays emitted by sub-pixel areas located on an inner side of the baffle are totally reflected at an interface of the thin film encapsulation layer to form a bright spot, so that a picture can also be displayed at the light-transmitting hole, thereby reducing the influence of a camera opening area below a screen on the integrity and aesthetics of the OLED display panel.
(FR)
L'invention concerne un panneau d'affichage à DELO flexible et son procédé de fabrication. Par le ménagement d'un trou de transmission de lumière dans un panneau d'affichage à DELO et la mise en place d'un déflecteur et d'une couche d'encapsulation de film mince à l'extérieur de plusieurs zones de sous-pixels autour du trou de transmission de lumière, certains rayons lumineux émis par des zones de sous-pixels situées d'un côté interne du déflecteur sont totalement réfléchis au niveau d'une interface de la couche d'encapsulation de film mince pour former un point lumineux, de sorte qu'une image puisse également être affichée au niveau du trou de transmission de lumière, ce qui permet de réduire l'influence d'une zone d'ouverture de caméra au-dessous d'un écran sur l'intégrité et l'esthétique du panneau d'affichage à DELO.

本揭示提供一种OLED显示面板及其制作方法,通过在OLED显示面板上设置透光孔以及在透光孔周围若干子像素区外设置有挡墙及薄膜封装层,位于所述挡墙内侧的子像素区发出的部分光线在薄膜封装层界面处发生全反射,形成亮点,使得透光孔处也可显示画面,降低了屏下摄像头开口区域对OLED显示面板完整性及美观性的影响。
