Description

Technical Field

[0001] This utility model relates to the field of display device technology, and in particular to a hidden display cover and a hidden display device. Background Technology

[0002] With the increasing intelligence of displays, hidden display technology, also known as "smart skin," is gradually being applied to various products. Currently, the surface cover of displays in electronic products such as mobile phones, tablets, and smartwatches is mostly concealed. This achieves an integrated design, creating a display device that is both stylish and technologically advanced while maintaining a clear view. The traditional process involves attaching a wood grain film (such as...) to the surface of the glass cover. Figure 3 As shown in the figure, the wood grain film has a low pencil hardness (around 3H@500g), poor scratch resistance, and an indistinct texture. In addition, the film material is expensive. Utility Model Content

[0003] In view of this, the purpose of this utility model is to provide a hidden display cover and a display device. The hidden display cover has high pencil hardness and low cost.

[0004] To achieve the above-mentioned objectives, this utility model provides the following technical solution:

[0005] This utility model provides a hidden display cover, comprising a glass substrate, a varnish layer, a texture layer, a reflective layer and a light-shielding layer stacked in sequence;

[0006] The surface of the glass substrate is divided into an outer surface and an inner surface;

[0007] The outer surface of the glass substrate has a textured surface.

[0008] The inner surface of the glass substrate is bonded to the varnish layer;

[0009] The light-shielding layer is attached to the outer periphery of the surface of the reflective layer.

[0010] Preferably, the depth of the textured surface is 8~20μm.

[0011] Preferably, the thickness of the varnish layer is 5~10μm.

[0012] Preferably, the thickness of the texture layer is 30~80μm.

[0013] Preferably, the thickness of the reflective layer is 6~15μm.

[0014] Preferably, the area of ​​the light-shielding layer that is attached to the periphery of the surface of the reflective layer accounts for 3% to 95% of the area of ​​the reflective layer.

[0015] The present invention also provides a hidden display device, comprising a hidden display cover, a display screen and a backlight arranged in sequence;

[0016] The hidden display cover is the hidden display cover described in the above technical solution;

[0017] The light-shielding layer side of the hidden display cover contacts the display screen.

[0018] Preferably, the hidden display cover and the display screen are bonded together by a transparent optical adhesive layer.

[0019] This invention provides a hidden display cover, comprising a glass substrate, a varnish layer, a texture layer, a reflective layer, and a light-shielding layer stacked sequentially. The surface of the glass substrate is divided into an outer surface and an inner surface. The outer surface of the glass substrate has an embossed texture. The inner surface of the glass substrate is bonded to the varnish layer. The light-shielding layer is bonded to the outer periphery of the reflective layer. This invention directly creates an embossed texture on the outer surface of the glass substrate to achieve a tactile feel, solving the problems of low pencil hardness, poor scratch resistance, and unclear tactile feel caused by attaching wood grain film to the glass substrate surface in traditional processes. This results in a surface pencil hardness of ≥9H@750g for the hidden display cover. Furthermore, by directly applying the embossed texture to the glass, the texture can be perfectly aligned with the glass, avoiding the problem of exposed white edges when attaching wood grain film to the glass cover in a 1:1 ratio, thus solving the problem of low yield.

[0106] The method for preparing a hidden display cover is as follows: First, a texture pattern is designed using AI or PS software according to actual needs; then, a photosensitive layer is coated on the surface of a PET substrate, and the photosensitive layer is exposed (the texture pattern is processed into a dot matrix image through RIP, then converted into a laser-controlled model, and then the laser beam of a laser typesetting machine is used to expose the photosensitive layer); finally, development (dissolving the exposed photosensitive layer in an alkaline developer), fixing (removing the unexposed photosensitive layer in an acidic fixer) and drying are performed sequentially to obtain the patterned film layer;

[0107] After sequentially depositing a photosensitive layer and a patterned film layer on one side of a glass substrate, ultraviolet exposure is performed, followed by development using an alkaline developer to dissolve the ultraviolet-exposed photosensitive layer, and etching using hydrofluoric acid with a mass percentage concentration of 8%. Then, photoresist is removed, chemical polishing is performed, CNC machining is performed, and chemical strengthening is performed to obtain a glass substrate with a textured surface on one side.

After baking and curing, a hidden display cover is obtained (according to JIS K 5600-5-4:1999, the measured value of the hidden display cover is between 9H and 10H (750g), which is not much different from the hardness of the glass itself).
