Problems solved by technology
[0004] An embodiment of the present invention provides a curved display panel, which is used to solve the problem of peeling between the second supporting layer and the adhesive layer at the bent portion of the curved display panel in the prior art due to the wrinkles caused by the adhesive layer being bent and squeezed. Not only will it affect the assembly of the whole machine, the reliability and reliability of the product, but it will also cause dead bends in some metal wiring at the bending part, which will affect the technical problems of the display effect.

Embodiment Construction
[0022] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. In the drawings, for clarity and ease of understanding and description, the dimensions and thicknesses of components depicted in the drawings are not to scale.
[0023] like figure 1 As shown, it is a schematic diagram of the basic structure of a curved display panel provided by an embodiment of the present invention. The curved display panel 10 includes: a display part A1 and a bending part A2 arranged oppositely, a first support layer 101, a second support layer 102 and Adhesive layer 103 . The display part A1 includes a flat area A11 and a curved area A12, the flat area A11 is connected to the bending part A2 through the curved area A12, and the first support layer 101 is provided on the display part A1 facing the On one side of the bending portion A2, the second s...

The present invention provides a curved display panel, a method for assembling the same, and a curved display device. The curved display panel includes a display part and a bending part arranged oppositely, the display part includes a flat area and a curved area, and the flat area is connected with the bending part through the curved area; the curved display panel also includes a display part facing the bending part. The first support layer on one side of the display part, the second support layer and the adhesive layer on the side of the bending part facing the display part, the first support layer and the second support layer are fixed by the adhesive layer; A first groove is provided on one side of the folded portion corresponding to the curved surface area. When the adhesive layer and the first supporting layer are pasted together, the first groove facing away from the first supporting layer can absorb the excess material formed by the bending and extrusion of the adhesive layer, so that the side of the adhesive layer facing the bending part will not be produced The wrinkles will not affect the bonding effect between the second support layer and the adhesive layer, and avoid peeling between the second support layer and the adhesive layer.
Description
technical field [0001] The present invention relates to the field of display technology, and in particular, to a curved display panel, a method for assembling the same, and a curved display device. Background technique [0002] In order to further increase the screen ratio of the display panel, the curved display panel came into being. The curved display panel refers to bending the display panel toward the backplane side, so that the side frame of the display panel also has a display function, that is, the screen ratio can be further increased. [0003] During the bending process of the curved display panel, the second support layer of the bending portion will also be bent. When the second support layer is in a bent state, it has a large rebound force. The second support layer is adhered and fixed to the first support layer of the display portion. However, after the adhesive layer is bent, the side facing the bending portion will be squeezed, resulting in wrinkles, which w...
