Intelligence and beauty have also become part of people's evaluation of products in the new era. As a window for intelligent control, the display device has become a part of intelligent control. For the sake of aesthetic effect, the display device is required to cooperate with the interior so that the overall integration with the environment can be achieved when the screen is off, and the display effect is not affected when the screen is on. However, the display effect of current display devices is poor. In the related technology, light sources and graphic icons are usually used to form an independent epidermal structure. The epidermal structure is directly attached to the display panel, which will lead to low transmittance of the display panel and high display power consumption.

[0030] In view of this, the embodiments of the present application provide a display panel and a method for preparing the same, and a display device. By directly forming a surface-coated film layer on a display substrate, the cover plate and polarizer structure in the display panel can be replaced, and the light transmittance of the display panel can be improved, thereby improving the display effect of the display panel. Furthermore, the surface-coated film layer, as a decorative structure of the display panel, has good light transmittance, thereby improving the integrated display effect of the display panel.

[0031] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application.

Compared with the related art of preparing the epidermis by printing, the present proposal adopts photolithography to prepare the epidermal film layer, which is more convenient to prepare, and the pattern of the epidermal film layer is precise and has a high degree of color combination, thereby improving the display effect of the display panel.

[0098] Optionally, in one embodiment, the preparation method may further include preparing a substrate layer on a side of the second color layer 20 facing away from the display panel, and patterning the substrate layer to form a texture to obtain a tactile texture layer 50 .
