Adhesive film used on folding OLED (Organic Light Emitting Diode) screen

The invention provides an adhesive film used on a folding OLED screen, and belongs to the technical field of new materials. The problem that in the prior art, applicability is poor is solved. The adhesive film for folding the OLED screen comprises an anti-bending layer, a base layer, an adhesive layer and a release film which are stacked and connected from top to bottom, the thickness size of the base layer and the release film is A, the thickness size of the anti-bending layer is B, A is 25-50 times of B, and the thickness size of the release film is equal to that of the base layer. The adhesive film for folding the OLED screen is high in applicability. 本发明提供了一种用于折叠OLED屏上的粘着膜，属于新材料技术领域。它解决了现有技术存在着适用性差的问题。本用于折叠OLED屏上的粘着膜包括由上至下层叠连接设置的抗弯折层、基层、粘结层和离型膜，所述基层与离型膜的厚度尺寸为A，所述抗弯折层的厚度尺寸为B，上述A为B的25-50倍，所述离型膜厚度尺寸与基层厚度尺寸相等。本用于折叠OLED屏上的粘着膜适用性高。
