Embodiment 1

[0036] Such as Figure 4 As shown, the preparation method of the curved cover plate provided in this embodiment includes:

[0037] A curved cover body 10 is provided, and the curved cover body 10 has a display area and a non-display area;

[0038] defining at least part of the non-display area as an area to be inked;

[0039] Spray ink 20 on the curved cover plate body 10, and the sprayed area covers the area to be coated with ink;

[0040] curing the ink 20;

[0041] Utilize the laser to clean the ink 20 outside the area to be coated with ink;

[0042] Clean the curved surface cover plate body 10 to remove the ink 20 other than the area to be coated with ink.

[0043] Spray ink 20 on the curved cover plate body 10, and use a laser to clean the ink 20 outside the area to be coated with ink after the ink 20 is cured. In this way, the ink 20 is directly attached to the curved cover plate body 10, reducing the optical cost during production. The adhesive layer and the thermo...

Embodiment 2

[0054] Such as Figure 7 As shown, this embodiment also provides a curved cover plate, including the curved cover plate made by using embodiment 1. The curved cover plate includes a display area and a non-display area, wherein the non-display area is sprayed with ink 20 .

[0055]Preferably in this embodiment, the curved cover is a 3D cover, that is, the entire surface is an arc. It can be compatible with flexible screens, and the combination of the two improves the image clarity of the display panel of the device, and the 3D cover has more advantages in terms of heat dissipation, gloss and wear resistance. At the same time, the curved design of the 3D cover matches the curvature of the palm, which is more in line with ergonomic requirements.

[0056] In this embodiment, since the ink 20 is sprayed on the curved cover body 10, there is no other medium between the two, no air bubbles will be generated, and the product yield rate is improved. The visual effect is better and t...

Embodiment 3

[0058] This embodiment also provides a display panel, including the curved cover plate manufactured by using the embodiment 1 or the curved cover plate of the embodiment 2. The display panel also includes: an upper polarizer, a liquid crystal panel and a lower polarizer.

[0059] In this embodiment, preferably, the display panel is a curved surface, which is compatible with the curved surface cover plate. This kind of display panel has clearer imaging, more intuitive visual experience, and the curved surface is easier for human eyes to see, less prone to fatigue, and the overall thickness is thinner and lighter. Lightweight, low power consumption, increased battery life. Since there are no air bubbles in the curved cover, defects caused by air bubbles are avoided, the visual effect is better, and the user experience is improved.

Abstract

The invention discloses a curved surface cover plate and a preparation method thereof. The preparation method of the curved surface cover plate comprises the steps: providing a curved surface cover plate body, wherein the curved surface cover plate body is provided with a display area and a non-display area and defining at least a part of the non-display area as an area to be coated with ink; spraying ink to the curved surface cover plate body, wherein the spraying area covers the area to be coated with the ink; curing the ink; cleaning the ink outside the area to be coated with the ink by utilizing laser; and cleaning the curved surface cover plate body, and removing the ink outside the area to be coated with ink. According to the method, the ink is sprayed on the curved surface cover plate body, and the ink outside the area to be coated with ink is cleaned by laser after the ink is cured, so that the ink is directly attached to the curved surface cover plate body, an optical adhesivelayer and a thermoplastic polyester layer are reduced during manufacturing, bubbles caused by pulling the thermoplastic polyester layer during adhesion are avoided, screen printing of the ink is notneeded, procedures are reduced, and the yield is improved.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a curved cover plate and a preparation method thereof, a display panel and electronic equipment. Background technique [0002] Cover plates are important components of electronic devices such as mobile phones, tablets, digital cameras or laptops. With the development of electronic equipment with curved screens, people have higher and higher requirements for the appearance, thinness and comfort of touch screens. The traditional flat cover is gradually upgraded to 2.5D, 3D and other special-shaped curved covers. 2.5D cover means that the edge of the cover has a smooth transition, and 3D cover means that the overall surface of the cover is a special-shaped arc, that is, the overall surface of the cover is a curved surface. Since the 3D cover is curved, it is difficult to print ink, such as Figure 1~3 As shown, at present, silk screen ink 11' is used on the thermoplastic polyester...
