Abstract
(EN)
Disclosed in the present invention is a display device, comprising: at least one bending area and non-bending areas connected to two sides of each bending area, each bending area being provided with a bending center line; and a substrate, the substrate being provided with several strip-shaped channels at a part corresponding to each bending area, and the length direction of each strip-shaped channel being parallel to the bending center line. The beneficial effects of the present invention are that in the display device of the present invention, materials commonly used for a substrate and a touch electrode in the prior art are replaced with a conductive film material having better flexibility; strip-shaped channels are arranged on the substrate, and the strip-shaped channels are folded during bending to reduce stress of the display device on a bending area, so that the risk of breaking the touch electrode due to stress is reduced.

La présente invention concerne un dispositif d'affichage, comprenant : au moins une zone de courbure et des zones de non flexion reliées à deux côtés de chaque zone de courbure, chaque zone de courbure étant pourvue d'une ligne centrale de courbure; et un substrat, le substrat étant pourvu de plusieurs canaux en forme de bande au niveau d'une partie correspondant à chaque zone de courbure, et la direction de la longueur de chaque canal en forme de bande étant parallèle à la ligne centrale de pliage. Les avantages de la présente invention résident en ce que, dans le dispositif d'affichage de la présente invention, des matériaux couramment utilisés pour un substrat et une électrode tactile selon l'état de la technique sont remplacés par un matériau de film conducteur ayant une meilleure flexibilité; des canaux en forme de bande sont agencés sur le substrat, et les canaux en forme de bande sont pliés pendant la courbure pour réduire la contrainte du dispositif d'affichage sur une zone de courbure, de telle sorte que le risque de rupture de l'électrode tactile due à une contrainte est réduit.

本发明公开了一种显示装置,包括至少一弯折区以及连接在每一弯折区两侧的非弯折区,每一弯折区具有一弯折中心线;基板,在每一弯折区对应部分,所述基板上设有若干条形沟道,每一条形沟道的长度方向平行于所述弯折中心线。本发明的有益效果在于本发明的显示装置采用柔韧性更好的导电薄膜材料代替现有技术中基底与触控电极常采用的材料,在基底上开设条形沟道,在弯折时条形沟道合拢减小显示装置在弯折区的应力,从而降低触摸电极由于受应力而断裂的风险。
