[0036] The above solution will be further described below with reference to specific embodiments. It should be understood that these embodiments are for illustrating the present invention and are not intended to limit the scope of the present invention. The implementation conditions used in the embodiments can be further adjusted according to the conditions of specific manufacturers, and the implementation conditions not specified are usually the conditions in conventional experiments.

[0037] like Figure 1 The diagram shown is a structural schematic of Embodiment 1 of this utility model, which provides a starry sky pattern cover plate, including a transparent substrate 1, a black ink layer 2 disposed on the transparent substrate 1, and a pattern ink layer 4 disposed on the black ink layer 2.

[0038] The transparent substrate 1 is made of glass and has a display area 1-1 in the center and an ink area 1-2 on the outer periphery of the display area 1-1.

[0039] The black ink layer 2 is printed on the ink area 1-2 of the transparent substrate 1 using screen printing technology. Several perforated holes 2-1 are provided on the black ink layer 2. In this example, a 420-mesh, 90-line polyester screen is used to screen print the black ink layer 2.

[0040] To improve the adhesion of the pattern ink layer 4 to the black ink layer 2, a base layer 3 is printed on the black ink layer 2. The base layer 3 is obtained by printing with Yuhao-mixed resin HBA8800.

[0041] A pattern ink layer 4 is jet-printed on the base coat layer 3, the pattern ink layer 4 includes a black covering part 4-1 and a plurality of color blocks 4-2 arranged on the black covering part 4-1 and corresponding to the plurality of hollow holes 2-1, the plurality of color blocks 4-2 have different gray scales and the gray scales are all less than that of the black covering part 4-1, and the size of each hollow hole 2-1 is greater than that of the corresponding color block 4-2.

[0042] The size of the hollow hole 2-1 is expanded by 0.2-1mm, preferably 0.3mm, based on the size of the corresponding color block 4-1.

[0043] The pattern ink layer 4 can be obtained by printing, such as a DLI-2513 printer, the color gray scale is controlled by editing the color gray scale with Illustrator through the rip software of the drawing software, the greater the gray scale of the color block 4-2, the more the ink amount of the jet printing, the deeper the color, and the lower the transmittance. Specifically, the gray scale is adjusted by the k value in the cmyk four colors, k=0 represents white, k=100 represents a pure black color block, and the K value between the two represents gray. The transmittance requirement of the patent embodiment is <10%, and therefore the gray scale K is set to 0-30.

[0044] The appearance of the cover plate prepared in Example 1 is shown in Figure 2 A starry night texture pattern is formed in the ink area 1-2 of the cover plate.

[0045] As shown in Figure 3 is a structural schematic view of the utility model embodiment 2, the same as that of the embodiment 1, the difference lies in that: first, the pattern ink layer 4 is attached to the black ink layer 2 through the adhesive, second, a semi-transparent ink layer 8 is printed below the black ink layer.

[0046] Specifically, it further includes a semi-transparent ink layer 8, a transparent support sheet 5 and an adhesive layer 6, the pattern ink layer 4 is jet-printed on the transparent support sheet 5, the semi-transparent ink layer is printed on the black ink layer 2, and the adhesive layer 6 is arranged between the pattern ink layer 4 and the printed semi-transparent ink layer 8 to paste the transparent support sheet 5 on the printed semi-transparent ink layer 8, wherein the transparent support sheet 5 can adopt a PET substrate. Since the substrate transmittance is about 60%, the pattern gray scale K jet-printed on the transparent support sheet 5 needs to be appropriately improved, and the gray scale K is set to 0-50.

[0047] Because the transparent support sheet 5 and adhesive layer 6 are not flexible enough, their adhesion to the black ink layer 2 is insufficient, causing air to easily become trapped in the gaps between them. When the screen is off, this trapped air affects the screen's integrity. To mitigate this, a semi-transparent ink layer 8 is printed between the black ink layer 2 and the adhesive layer 6. This semi-transparent ink layer 8 is printed below the black ink layer 2, with a transmittance of 10-50%, preferably 15-25%. It is printed using Seiko Ink HF GV3 series BLACK6009 ink, which has fine toner and is easy to print.

[0048] The size of the cutout hole 2-1 is 0.2-1mm larger than the size of the corresponding color block 4-2. Considering the fitting accuracy, it is preferred to expand it by 0.5mm.

[0049] To further improve the precision of the fit, such as Figure 4 As shown, a white bonding frame 7 is printed on the black ink layer 2 to serve as a bonding mark. During conventional ink printing, to facilitate bonding between the cover plate and the module, a marking frame is usually printed on the outer periphery of the display area 1-1 on the black ink layer 2. This marking frame uses Seiko marking ink. The white bonding frame 7 in this example can also be printed using Seiko marking ink.

[0050] In summary, the manufacturing process of this cover plate is simple, solves the problem that screen printing cannot print small perforations and color blocks, and improves production efficiency.

[0051] The above examples are only for illustrating the technical concept and features of this utility model, and are intended to enable those skilled in the art to understand the content of this utility model and implement it accordingly. They should not be used to limit the scope of protection of this utility model. All equivalent changes or modifications made in accordance with the spirit and essence of this utility model should be included within the scope of protection of this utility model.
