Abstract
(EN) Provided are a TFT array substrate, an AMOLED display apparatus, and a method for preparing a TFT array substrate. A light conversion layer is arranged on a TFT array substrate, light of three primary colors is emitted by means of combining a monochrome light-emitting layer with the light conversion layer, and incident ambient light is absorbed by means of the light conversion layer. By means of the AMOLED display apparatus of the present invention, the aim of preventing the reflection of ambient light without the need for a polarizer is achieved, the light emission efficiency of an OLED device and the brightness of the AMOLED display apparatus are improved, power consumption is reduced, and costs are also saved.
(FR) La présente invention concerne un substrat de réseau TFT, un appareil d'affichage AMOLED et un procédé de préparation d'un substrat de réseau TFT. Une couche de conversion de lumière est disposée sur un substrat de réseau TFT, une lumière de trois couleurs primaires est émise au moyen de la combinaison d'une couche émettrice de lumière monochrome avec la couche de conversion de lumière, et la lumière ambiante incidente est absorbée au moyen de la couche de conversion de lumière. Au moyen de l'appareil d'affichage AMOLED de la présente invention, l'objectif de la présente invention est d'empêcher la réflexion de la lumière ambiante sans qu'il soit nécessaire de recourir à un polariseur, l'efficacité d'émission de lumière d'un dispositif OLED et la luminosité de l'appareil d'affichage AMOLED sont améliorées, la consommation d'énergie est réduite, et les coûts sont également économisés.
(ZH) 本发明提供一种TFT阵列基板、AMOLED显示装置、和TFT阵列基板的制备方法,通过在TFT阵列基板上设置光转换层,利用单色发光层和光转换层结合的方式发出三原色光,通过光转换层吸收入射的环境光;本发明AMOLED显示装置实现了无需偏光片也可防止环境光反射的目的,提高了OLED器件的发光效率和AMOLED显示装置的亮度,降低了功耗,同时节约了成本。
