Title
(EN) OLED DISPLAY PANEL
(FR) PANNEAU D'AFFICHAGE DELO
(ZH) OLED显示面板
Abstract
(EN)
An OLED display panel (100) comprises a display region (10) and a through hole (30) for placement of an electronic element. The display region (10) is arranged around the through hole (30). The display region (10) comprises a barrier structure (20) and an encapsulation structure layer (12) covering the barrier structure (20). The barrier structure (20) is provided at a peripheral side of the through hole (3). In the invention, the encapsulation structure layer (12) extends toward and covers the barrier structure (20) from the display region (10), thereby preventing the ingress of moisture into an organic light-emitting layer (114) at the display region (10).
(FR)
Selon la présente invention, un panneau d'affichage DELO (100) comprend une région d'affichage (10) et un trou traversant (30) destiné au placement d'un élément électronique. La région d'affichage (10) est disposée autour du trou traversant (30). La région d'affichage (10) comprend une structure de barrière (20) et une couche de structure d'encapsulation (12) recouvrant la structure de barrière (20). La structure de barrière (20) est disposée au niveau d'un côté périphérique du trou traversant (3). Selon l'invention, la couche de structure d'encapsulation (12) s'étend vers la structure barrière (20) et la recouvre à partir de la région d'affichage (10), ce qui empêche de ce fait l'entrée d'humidité dans une couche électroluminescente organique (114) au niveau de la région d'affichage (10).
