Problems solved by technology

At present, the main solution is to reduce the thickness of OCA as much as possible. Although reducing the thickness of OCA can improve the problem of OCA creases in the folding area, there is also the problem that OCA cannot effectively fill the thickness difference between different laminates and maintain good and effective adhesion. adhesion, with the risk of air bubbles

Embodiment Construction

[0018] The display device provided by the present invention will be described in detail below with reference to the drawings and embodiments. Apparently, the described embodiments are only some of the embodiments of the present invention, but not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0019] refer to Figure 4-5 ,in Figure 4 is a plan view of the display device of the present invention, Figure 5 for along Figure 4 Sectional view of the strut structure at cutting line A-A'. The display device can be folded in half along the folding central axis 410, and the area is reduced by half after folding, and can be used normally like a mobile phone or a tablet computer after being unfolded. Specifically, the display device includes a display panel, a touch sensing layer 411 sequentially arranged...

Abstract

A display device is disclosed. An elastic support column is made in a folded area on the surface of a touch-sensitive layer, and an adhesive is filled around the elastic support column. The height ofthe elastic support column varies according to the change of the extrusion stress. And the thickness of the adhesive can be controlled by adjusting the height and density of the elastic support columnto ensure optimum folding effect. The invention can keep the appearance of the product without obvious change before and after folding, and avoid the adhesive deformation caused by thick adhesive andrepeated folding from being irrecoverable, thereby realizing flexible foldable touch display.

Description

technical field [0001] The present invention relates to the technical field of flexible display, in particular to a display device for flexible and foldable touch display. Background technique [0002] In recent years, the rapid development of OLED (Organic Light Emitting Diode, Organic Light Emitting Diode) display technology has promoted the rapid entry of curved surface and flexible touch display products into the market, and technological updates in related fields are also changing with each passing day. OLED refers to a diode that uses organic semiconductor materials and light-emitting materials to cause light emission through carrier injection and recombination under the drive of an electric field. [0003] For the current common fixed curvature product design, due to the large bending radius and fixed shape, the technical difficulty is relatively low, so it is also the easiest to implement. However, for foldable products, because the product needs to withstand long-t...
