Abstract
(EN)
Provided are a display panel and a method for fabrication thereof; the display panel is provided with a target light transmission layer on a target light conversion layer, enabling a target light passing through the target light conversion layer to be transmitted therethrough while an excitation light passing through the target light conversion layer is reflected, thus the emitted target light is mixed with a small amount of excitation light or no excitation light, making purer the target light emitted by a subpixel unit, thereby solving the technical problem of defects present in the existing micro display technology.
(FR)
L'invention concerne un panneau d'affichage et un procédé de fabrication associé ; le panneau d'affichage est pourvu d'une couche de transmission de lumière cible sur une couche de conversion de lumière cible, ce qui permet à une lumière cible traversant la couche de conversion de lumière cible d'être transmise à travers celle-ci tandis qu'une lumière d'excitation traversant la couche de conversion de lumière cible est réfléchie. La lumière cible émise est ainsi mélangée avec une faible quantité de lumière d'excitation voire aucune lumière d'excitation, ce qui rend la lumière cible émise par une unité de sous-pixel plus pure et permet de résoudre le problème technique des défauts présents dans la technologie de micro-affichage existante.

一种显示面板及其制备方法,显示面板通过在目标光转换层上设置目标光透过层,使得穿过目标光转换层的目标光透过,而穿过目标光转换层的激发光被反射,使得出射的目标光少量混有激发光甚至不混有激发光,使得子像素单元出射的目标光较纯,从而解决了现有微显示技术存在缺陷的技术问题。
