Abstract
(EN)
The present application provides foam, comprising a conductive adhesive, a drawable component, and a conductive frame. The drawable component is provided in the conductive frame; the conductive adhesive comprises a first conductive adhesive layer and a second conductive adhesive layer, and the conductive frame is provided between the first conductive adhesive layer and the second conductive adhesive layer; a first surface of the conductive frame is adhered to a first surface of the first conductive adhesive layer, and a second surface of the conductive frame is adhered to a first surface of the second conductive adhesive layer. According to the present application, two conductive adhesive layers are provided and a drawable component is provided in a conductive frame, so that in practical application, the drawable component is removed to reduce the thickness of foam, thereby avoiding the problem of white spots on a display screen caused by the thickness of common foam. In addition, the conductive effect can also be enhanced by providing a foam structure comprising two conductive adhesive layers, so as to achieve electric connection between a middle frame and a display screen assembly in a display area.

La présente invention concerne de la mousse, comprenant un adhésif conducteur, un composant étirable et un cadre conducteur. Le composant étirable est disposé dans le cadre conducteur. L'adhésif conducteur comprend une première couche adhésive conductrice et une seconde couche adhésive conductrice, et le cadre conducteur est disposé entre la première couche adhésive conductrice et la seconde couche adhésive conductrice. Une première surface du cadre conducteur est collée à une première surface de la première couche adhésive conductrice, et une seconde surface du cadre conducteur est collée à une première surface de la seconde couche adhésive conductrice. Selon la présente invention, deux couches adhésives conductrices et un composant étirable sont disposés dans un cadre conducteur, de telle sorte que, dans une application pratique, le composant étirable est retiré pour réduire l'épaisseur de mousse, ce qui permet d'éviter le problème des taches blanches sur un écran d'affichage provoqué par l'épaisseur de mousse commune. De plus, l'effet conducteur peut également être amélioré en fournissant une structure en mousse comprenant deux couches adhésives conductrices, de façon à réaliser une connexion électrique entre un cadre intermédiaire et un ensemble écran d'affichage dans une zone d'affichage.

本申请提供了一种泡棉,包括:导电胶、可抽出部件和导电框;可抽出部件设置在导电框内;导电胶包括第一层导电胶和第二层导电胶,导电框设置在第一层导电胶和第二层导电胶之间;其中,导电框的第一表面与第一层导电胶的第一表面粘连,导电框的第二表面与第二层导电胶的第一表面粘连。本申请,通过设置两层导电胶以及在导电框之间设置可抽出部件,可以在实际使用时,移除可抽出部件以降低泡棉厚度,避免了普通泡棉由于自身厚度的原因在显示屏上造成白斑的问题。此外,通过设置两层导电胶的泡棉结构还可以加强导电效果,实现在显示区域完成中框和显示屏组件之间电连接。
