[0061] The present application is described in detail below with reference to the accompanying drawings and embodiments.

[0062] See also Figure 1 , Figure 2 , Figure 3 , Figure 4 as well as Figure 5 , Figure 1 A schematic diagram of the structure of a display device provided in the first embodiment of the present application. Figure 2 A schematic diagram of the specific structure of the display panel. Figure 3 It is a schematic diagram of the specific structure of the decorative panel. Figure 4 This is a top view schematic diagram of a finishing shading layer. Figure 5 This is a top view schematic diagram of another finishing shading layer.

[0063] The first embodiment of the present application provides a display device 1000, which includes a display panel 100. The display panel 100 includes a plurality of functional layers and a decorative light shielding layer 10. The decorative light shielding layer 10 is disposed on the plurality of functional layers, and the decorative light shielding layer 10 also has a plurality of hollow portions L disposed at intervals, and the hollow portions L are used to expose the display panel 100 so that the displayed image is exposed. Figure 4 and Figure 5 , the hollow portion L is an array of through holes A1 or parallel gaps A2. The display panel 100 may be a liquid crystal display panel, an inorganic light emitting diode (LED) display panel, or an organic light emitting diode (OLED) display panel. In the embodiment of the present application, the liquid crystal display panel 100 is mainly used as an example for detailed description.

[0064] The finishing light-shielding layer 10 includes a first finishing light-shielding layer 101 and a second finishing light-shielding layer 102. The first finishing light-shielding layer 101 and the second finishing light-shielding layer 102 are respectively arranged on different functional layers, and the pattern of the first finishing light-shielding layer 101 and the pattern of the second finishing light-shielding layer 102 cooperate to form the pattern of the finishing light-shielding layer 10. In a specific production process, the first finishing light-shielding layer 101 and the second finishing light-shielding layer 102 can be prepared separately to improve production efficiency.

[0065] The display panel 100 further includes a display module 20. The display module 20 includes a first substrate 201 and a first polarizing layer 202. The first substrate 201 has a light emitting surface 201a. The first polarizing layer 202 is disposed on one side of the light emitting surface 201a of the first substrate 201, and both the first substrate 201 and the first polarizing layer 202 serve as functional layers.

[0066] In a specific embodiment, the display module 20 is a liquid crystal display module 20, which further includes a common electrode layer 205, a second substrate 206, a liquid crystal layer 207, a transparent electrode layer 208, a driving circuit layer (not shown) and a second polarizing layer 209. The common electrode layer 205 is disposed on a side of the first substrate 201 close to the liquid crystal layer 207; the second substrate 206 is disposed on a side of the first substrate 201 away from the light emitting surface 201a; the light emitting layer or liquid crystal layer 207 is sandwiched between the first substrate 201 and the second substrate 206; the transparent electrode layer 208 is disposed on a side of the second substrate 206 close to the liquid crystal layer 207; a driving circuit layer is disposed on a side of the second substrate 206 close to the light emitting surface 201a, and the driving circuit layer is used to drive the display panel 100 to emit light; and the second polarizing layer 209 is disposed on a side of the second substrate 206 away from the light emitting surface 201a.

[0067] Specifically, the first substrate 201 and the second substrate 206 can be made of materials such as glass, acrylic acid, and polycarbonate.

[0068] Further, the display device 1000 also includes a decorative plate 200. The decorative plate 200 has an opening 200a. The decorative plate 200 can be a wooden plate, a ceramic plate or a plastic plate, etc.; the decorative plate 200 can be a decorative plate 200 of a wall or an interior panel of a car, etc. The opening 200a can be a through hole A1 or a groove. The surface of the decorative plate 200 has a facing area, and the facing area has a pattern that matches the pattern of the facing light shielding layer 10. Among them, the display panel 100 is embedded in the opening 200a, and the light emitting surface 201a of the display panel 100 is oriented in the same direction as the facing area of ​​the decorative plate 200. The color and / or pattern of the facing area matches the facing light shielding layer 10, that is, the color or pattern of the color ink included in the facing light shielding layer 10 is the same as or matches the color or pattern of the facing area, so that the display panel 100 and the decorative plate 200 are better integrated.

[0069] In this embodiment, the first finishing light shielding layer 101 is arranged on the light emitting surface 201a of the first substrate 201, and the second finishing light shielding layer 102 is arranged on the surface of the first polarizing layer 202 facing the first substrate 201. Specifically, the pattern of the first finishing light shielding layer 101 and the pattern of the second finishing light shielding layer 102 are both patterns formed by the four-color printing achromatic principle (CMYK, CYAN-MAGENTA-YELLOW-BLACK INK: cyan-magenta-yellow-black). In the process of presenting the decorative pattern, the pattern of the first finishing light shielding layer 101 and the pattern of the second finishing light shielding layer 102 are staggered and complementary, so that the pattern can be enriched; wherein complementary means that the pattern of the first finishing light shielding layer 101 and the pattern of the second finishing light shielding layer 102 can form a complete pattern. In this embodiment, the four-color printing decolorization principle is adopted, which can be understood as follows: for example, if a decorative pattern finally presents both landscape and animal or human patterns, then one of the patterns of the first decorative light-shielding layer 101 and the second decorative light-shielding layer 102 is landscape, and the other is animal or human. The display device 1000 has a better display effect by displaying the patterns of the first decorative light-shielding layer 101 and the second decorative light-shielding layer 102 in coordination, thereby increasing the invisible value of the display device 1000.

[0070] Specifically, the first facing light shielding layer 101 has a plurality of first hollow portions arranged at intervals, and the second facing light shielding layer 102 has a plurality of first hollow portions arranged at intervals. The first hollow portions may be through holes A1 arranged in an array or slits A2 arranged in parallel and at intervals. The first hollow portions may also be through holes A1 arranged in an array or slits A2 arranged in parallel and at intervals.

[0071] It is understandable that the first decorative light shielding layer 101 in this embodiment can also be arranged on the light emitting surface 201a of the first substrate 201, and the second decorative light shielding layer 102 can also be arranged on the surface of the first polarizing layer 202 facing the first substrate 201. As long as the first decorative light shielding layer 101 and the second decorative light shielding layer 102 can cooperate to form a pattern of the decorative light shielding layer 10 with richer content, the display effect of the display device 1000 can be better.

[0072] See also Figure 6 , Figure 7 as well as Figure 8 , Figure 6 A schematic diagram of the structure of a display device provided in the second embodiment of the present application; Figure 7 is a schematic diagram of the specific structure of the display panel; Figure 8 : is a simplified schematic diagram of the first decorative light-shielding layer and the second decorative light-shielding layer in the second embodiment. The structure of the display device 1000 provided in the second embodiment of the present application is the same as the structural substrate of the display device 1000 in the first embodiment, except that the display module 20 in this embodiment further includes an optical adhesive layer 203 and a cover plate 204. Among them, the display panel 100 in this embodiment includes a display module 20. The display module 20 includes a first substrate 201, a first polarizing layer 202, an optical adhesive layer 203 and a cover plate 204. The first substrate 201 has a light-emitting surface 201a. The first polarizing layer 202 is arranged on one side of the light-emitting surface 201a of the first substrate 201. The optical adhesive layer 203 is arranged on the side of the first polarizing layer 202 away from the first substrate 201. The cover plate 204 is arranged on the side of the optical adhesive layer 203 away from the first substrate 201 to protect the light-emitting surface 201a of the display panel 100. Specifically, the first substrate 201 , the first polarizing layer 202 and the cover plate 204 all serve as functional layers.

[0073] In this embodiment, the first decorative light shielding layer 101 is arranged on one side of the light emitting surface 201a of the first substrate 201, and the second decorative light shielding layer 102 is arranged on the surface of the cover plate 204 facing the first substrate 201. It can be understood that in a specific embodiment, the first decorative light shielding layer 101 can also be arranged on the surface of the first polarizing layer 202 facing the first substrate 201, and the second decorative light shielding layer 102 can also be arranged on the surface of the cover plate 204 facing the first substrate 201; or, the first decorative light shielding layer 101 can also be arranged on the surface of the first polarizing layer 202 away from the first substrate 201, and the second decorative light shielding layer 102 can also be arranged on the surface of the cover plate 204 facing the first substrate 201. As long as the first decorative light shielding layer 101 and the second decorative light shielding layer 102 can cooperate to form a pattern of the decorative light shielding layer 10 with richer content.

[0074] In this example, the pattern of the first decorative light-shielding layer 101 and the pattern of the second decorative light-shielding layer 102 can be formed by the four-color printing decolorization principle as in the first embodiment. Another method can also be adopted: the pattern of the first decorative light-shielding layer 101 is a pattern formed by ink of a part of the colors in the four-color printing decolorization principle, and the pattern of the second decorative light-shielding layer 102 is a pattern formed by ink of another part of the colors in the four-color printing decolorization principle. It can be understood that, for example, if there is a decorative pattern that eventually presents a rich variety of colors, then the decorative pattern is peeled off layer by layer, each layer of the decorative shading layer 10 controls the distribution of ink of one color, and finally each layer of the decorative shading layer 10 is superimposed to make the picture present richer colors; in this embodiment, it can be specifically expressed as the pattern of the first decorative shading layer 101 is a pattern formed by ink of a part of the colors in the four-color printing achromatic principle, and the pattern of the second decorative shading layer 102 is a pattern formed by ink of another part of the colors in the four-color printing achromatic principle; finally, the first decorative shading layer 101 and the second decorative shading layer 102 are combined to present the desired rich colors.

[0075] Among them, reference Figure 8 The black ink layer B is separately arranged at the bottom layer of the decorative light-shielding layer 10. At this time, the black ink layer B is a black light-blocking layer, which is used to shield the decorative light-shielding layer 10 to prevent the light of the display panel 100 from penetrating the decorative light-shielding layer 10 when the display panel 100 is displayed, causing the pattern of the display panel 100 to affect the pattern of the decorative light-shielding layer 10. The pattern of the first decorative light-shielding layer 101 and the pattern of the second decorative light-shielding layer 102 are at least partially stacked and the pattern of the decorative light-shielding layer 10 is formed by the principle of four-color printing decolorization; the first decorative light-shielding layer 101 has a plurality of first hollow portions arranged at intervals, and the second decorative light-shielding layer 102 has a plurality of first hollow portions arranged at intervals, and the plurality of first hollow portions and the plurality of first hollow portions are arranged correspondingly.

[0076] In a specific embodiment, a display device 1000 is provided for any one of the above two embodiments. The decorative light-shielding layer 10 of the display panel 100 includes a cyan ink layer, a magenta ink layer, a yellow ink layer and a black ink layer B which are stacked; the black ink layer B is located on the side of the three ink layers close to the first substrate 201, and the pattern of the black ink layer B is the same as the pattern of the decorative light-shielding layer 10. Because the black ink layer B can block part of the emitted light when the display panel 100 displays an image, the image displayed by the display panel 100 is prevented from being mixed with the pattern of the decorative light-shielding layer 10. The black ink layer B covers all areas except the areas corresponding to the light-emitting surface 201a of the first substrate 201 and the multiple hollow portions L. Specifically, the black areas of the pattern of the decorative light-shielding layer 10 are all hollowed out to form the hollow portions L, and the display brightness of the display panel 100 can be further improved by utilizing the feature that the display panel 100 appears black when the screen is off.

[0077] It can be understood that in other embodiments, the finishing light-shielding layer 10 may not only include the pattern of the first finishing light-shielding layer 101 and the second finishing light-shielding layer 102, but may also include a third finishing light-shielding layer, etc. Different finishing light-shielding layers are arranged on the surfaces of different functional layers.

[0078] See also Fig. 9 , Fig. 9 A flowchart of the steps of a method for preparing a display device provided in an embodiment of the present application. The present application also provides a method for preparing a display device 1000. The method for preparing the display device 1000 involved in the above embodiment includes:

[0079] Step S01: a first finishing light-shielding layer is disposed on the first functional layer; the first finishing light-shielding layer has a plurality of first hollow portions disposed at intervals.

[0080] Step S02: a second finishing light-shielding layer is disposed on the second functional layer; the second finishing light-shielding layer has a plurality of first hollow portions disposed at intervals.

[0081] Step S03: preparing a display panel using the first functional layer having the first finishing light-shielding layer and the second functional layer having the second finishing light-shielding layer.

[0082] In step S01 and step S02, a plurality of first hollow portions and a plurality of first hollow portions arranged at intervals are opened on the first finishing light-shielding layer 101 and the second finishing light-shielding layer 102 mainly by laser engraving or exposure or other processes.

[0083] Here, the display device 1000 in the second embodiment is mainly prepared as an example for further detailed description. The first functional layer is the first substrate 201 or the first polarizing layer 202, and the second functional layer is the cover plate 204. The display panel 100 is prepared by using the first functional layer having the first decorative light shielding layer 101 and the second functional layer having the second decorative light shielding layer 102, see Fig.10 , Fig.10 A flowchart of a method for manufacturing a display device according to another embodiment of the present application. The steps of the method for manufacturing the display device specifically include:

[0084] Step S001: preparing a display module using a first functional layer having a first finishing shading layer; the display module includes a first substrate and a first polarizing layer; the first finishing shading layer is arranged on a surface of the first substrate facing the first polarizing layer, or on a surface of the first polarizing layer facing the first substrate.

[0085] Step S002: an optical adhesive layer is disposed on a surface of the first polarizing layer away from the first substrate, or an optical adhesive layer is disposed on a surface of the second finishing light shielding layer away from the cover plate.

[0086] Step S003: curing the optical adhesive layer.

[0087] Step S004: bonding the cover plate and the first polarizing layer via a cured optical adhesive layer, so that the second finishing light-shielding layer is disposed between the cover plate and the cured optical adhesive layer.

[0088] The optical adhesive is first cured to form the optical adhesive layer 203 , which is convenient for subsequent peeling and replacement of the cover plate 204 , such as replacement of a cover plate 204 with a different pattern due to misalignment.

[0089] See also Fig.11 , Fig.11 The present invention is a structural schematic diagram of a method for preparing a first decorative light-shielding layer disposed on a surface of a first substrate facing a first polarizing layer.
