Embodiment Construction

[0046] The technical solutions of the present invention will be further described below in conjunction with the accompanying drawings and through specific implementation methods. It should be understood that the specific embodiments described here are only used to explain the present invention, but not to limit the present invention. In addition, it should be noted that, for the convenience of description, only some structures related to the present invention are shown in the drawings but not all structures.

[0047]As mentioned in the background, when the display device in the prior art is bent, the bending stress in the bending area is relatively concentrated, and the bending stress cannot be buffered and released, thus causing the module material in the bending area to break. At the same time, in the bending area, the inner surface of the film layer in the display device is subjected to compressive bending stress, while the outer surface of the film layer is subjected to te...

Abstract

The invention discloses a display panel and a display device. The display panel comprises at least one bending area, and the display device further comprises a substrate; a stress release layer, wherein at least one first groove is formed in the stress release layer, and the first groove is located in the bending area, and a first notch is formed on a first surface of one side, close to the coverplate, of the stress release layer. The first groove is filled with a flexible material, and the elastic modulus of the flexible material is less than that of the stress release layer. The display panel also comprises the cover plate which is located at one side of the substrate, wherein the stress release layer is located at one side, close to the substrate, of the cover plate, and at least one second groove is formed in the cover plate. The second groove is provided with a second notch in the second surface, close to one side of the stress release layer, of the cover plate, and the orthographic projection of the second notch and the orthographic projection of the first notch on the substrate are overlapped. According to the display device, the problems that module materials in the display device are broken and the display device is layered when the display device is bent are solved, and the display effect of the display device is improved.

Description

technical field [0001] Embodiments of the present invention relate to the field of display technology, and in particular, to a display panel and a display device. Background technique [0002] Organic light-emitting diode (Organic Light-Emitting Diode, OLED) display device, also known as organic electroluminescent display device, is a new type of flat panel display device. High, light and thin, fast response, and easy to realize the advantages of color display, large-screen display and flexible display, etc., it has broad application prospects. [0003] When the OLED display device is bent and deformed, the module material inside the OLED display device located in the bending area may break due to stress concentration, and the OLED display device will also be delaminated due to uneven force, resulting in OLED display The display of the device fails. Contents of the invention [0004] In view of this, the purpose of the present invention is to provide a display panel and ...
