Embodiment Construction

[0044] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the drawings in the embodiments of the present invention. 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 those skilled in the art without creative efforts fall within the protection scope of the present invention.

[0045] At present, part of the film layer is usually bent to the other side to reduce the frame to form the first layer and the second layer. During the bending and bonding process, due to the different thickness of the components and the film layer, there will be a step difference. The layer is easily deformed under pressure, which eventually leads to deformation of the display panel, resulting in imprinting, which affects normal display.

Abstract

The invention discloses a display panel and a display device. The display panel comprises a first area, a second area far away from one side of the first area and a bending area located between the first area and the second area. The display panel comprises: a display panel main body; a first layer located in the first area, wherein the first layer comprises a third layer located on one side of the display panel body and a reinforcing layer located on one side of the third layer; a second layer located in the second area, wherein the second layer is located on the side, away from the display panel main body, of the reinforcing layer; and a connecting member located between the reinforcing layer and the second layer, wherein the hardness of the reinforcing layer is greater than that of the third layer. According to the embodiment of the invention, the reinforcing layer with high hardness is arranged between the display panel main body and the connecting member, so that the pressed deformation quantity of the film layer of the display panel is reduced in the bending and attaching process of the film layer, and the impressions of the display panel are reduced.

Description

technical field [0001] The present invention relates to the display field, in particular to a display panel and a display device. Background technique [0002] In recent years, display panels are developing in the direction of flexible folding, narrow bezels, and high screen-to-body ratios. [0003] At present, part of the film layer is usually bent to the other side to reduce the frame to form the first layer and the second layer. During the bending and bonding process, due to the different thickness of the components and the film layer, there will be a step difference. The layer is easily deformed under pressure, which eventually leads to deformation of the display panel, resulting in imprinting, which affects normal display. [0004] Therefore, there is an urgent need for a display panel and a display device to solve the above technical problems. Contents of the invention [0005] Embodiments of the present invention provide a display panel and a display device to sol...
