[0004] However, due to the soft material of the optical glue, it cannot provide enough support for the hardened coating film. If it is pressed hard against the display panel, the optical glue is easily deformed, and the hardened coating film is easily broken, bent and broken, which greatly reduces the hardening effect.

Embodiment Construction
[0044] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. 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.
[0045] As mentioned in the background, in the existing organic light-emitting display devices, the light-emitting units in the display panel are usually protected by a hard coating film, and the hard coating film is bonded to the touch structure of the display panel by optical glue.
[0046] Due to the soft material of the optical adhesive, it cannot provide enough support for the hardened coating film. When the hardened coating film is placed on the optical adhesive, if it is pressed hard on the display panel duri...

Abstract
The invention discloses a manufacturing method of a display panel, a display panel and a display device. The manufacturing method of the display panel includes: providing a first base; forming a plurality of light-emitting units on the first base; One side of the touch structure forms a touch structure; wherein, the touch structure includes a first polyimide material layer, and the first polyimide material layer is a surface away from the side of the light-emitting unit; on the first polyimide layer of the touch structure The surface of the amine material layer is coated with a hardened layer; the hardened layer is hardened to form a hardened coating. Embodiments of the present invention provide a method for manufacturing a display panel, a display panel, and a display device, which improve the rigidity of the display panel and the display device, and also make the entire display panel and the display device lighter and thinner.
Description
technical field [0001] Embodiments of the present invention relate to the field of display technology, and in particular, to a method for manufacturing a display panel, a display panel, and a display device. Background technique [0002] With the development of display technology, organic light-emitting display devices are more and more widely used. [0003] In existing organic light-emitting flexible display devices, the light-emitting unit in the display panel is usually protected by a hard coating film. The hard coating film is a hard film that is bonded to the touch structure of the display panel by optical glue. [0004] However, due to the soft material of the optical glue, it cannot provide enough support for the hardened coating film. If it is pressed hard against the display panel, the optical glue is easily deformed, and the hardened coating film is easily broken, bent and broken, which greatly reduces the hardening effect. The hardness of the coating film. Cont...
