Title
(EN) COVER WINDOW AND FLEXIBLE DISPLAY DEVICE
(FR) FENÊTRE DE COUVERCLE ET DISPOSITIF D’AFFICHAGE FLEXIBLE
(ZH) 保护盖板以及柔性显示装置
Abstract
(EN)
A cover window (1) for a flexible display device (2) comprises a bendable portion (11) and an unbandable portion (12). The bendable portion (11) has a Young's modulus lower than a Young's modulus of the unbandable portion (12). The bendable portion (11) can pass a bendability test because of the lower Young's modulus while the unbandable portion (12) can pass a pressure test because of the higher Young's modulus. The invention solves a technical problem in the art in which an unbendable portion of a cover window cannot pass a pressure test easily.
(FR)
L’invention concerne une fenêtre de couvercle (1) pour un dispositif d’affichage flexible (2) qui comprend une partie pliable (11) et une partie non pliable (12). La partie pliable (11) a un module de Young inférieur à un module de Young de la partie non pliable (12). La partie pliable (11) peut réussir un essai de pliabilité en raison du module de Young inférieur tandis que la partie non pliable (12) peut réussir un essai de pression en raison du module de Young supérieur. L’invention résout un problème technique selon l’état de la technique dans lequel une partie non pliable d’une fenêtre de couvercle ne peut réussir facilement un essai de pression.
(ZH)
一种用于柔性显示装置(2)的保护盖板(1),包括弯曲部(11)以及非弯曲部(12),弯曲部(11)的杨氏模量小于非弯曲部(12)的杨氏模量。这样由于保护盖板(1)的弯曲部(11)具有较低的杨氏模量可以通过弯折性测试,同时非弯折部(12)具有较高的杨氏模量可以通过压力测试,解决了现有保护盖板存在的非弯折部难以通过压力测试的技术问题。
