Abstract

The invention provides a display device. The display device comprises a supporting layer, a first adhesive layer, a display panel, a fourth adhesive layer and cover plate glass. The supporting layer is designed into a sandwich structure; the supporting layer comprises at least two layers of metal sheets and a second adhesive layer clamped between the two layers of metal sheets; holes are dug in the two layers of metal sheets, and the two layers of metal sheets are filled with a third adhesive layer, so that the supporting layer has better curling performance and higher bonding strength, and the adhesive layer is effectively prevented from falling off in the bending process. The display panel can be well supported, and flexibility and rigidity are integrated.

Description

technical field [0001] The present invention relates to the field of display technology, in particular to a display device. Background technique [0002] In the existing technology, active matrix organic light-emitting diodes (AMOLED) are expected to replace liquid crystals and become the mainstream choice for next-generation displays due to their high contrast ratio, wide viewing angle, fast response speed, and flexibility. [0003] At present, the glue peeling problem of the bendable flexible panel occurs during the bending test process, that is, the backplane of the panel and the metal sheet are separated, resulting in poor separation of the screen after the mobile phone is made into a finished product, which cannot meet customer needs. Such as figure 1 As shown, the reason for the failure is analyzed. On the one hand, it is caused by insufficient adhesive force between the panel 11 and the support layer 12 (metal sheet), and on the other hand, the metal sheet forms a wa...
