Description

Technical Field

[0001] The utility model relates to the technical field of cover plates, in particular to the field of color cover plates. Background Art

[0002] In pursuit of a better driving experience, users have increasingly diverse requirements for vehicle instrument screens. In order to better meet customers' requirements for interior color integration, it is necessary to make the color of the vehicle screen consistent with the interior, which requires the production of a colored vehicle screen. To achieve this color effect, it is conventionally achieved by silk-screening ink on the back of the cover. After the silk-screening ink is printed on the back of the cover and bonded to the optical adhesive layer, due to the material and printing flatness, ink steps often occur, which affects the visual effect or product yield. In addition, the color of the silk-screen ink is difficult to mix and needs to be customized, which not only affects the visual effect but also increases the production cost. Utility Model Content

[0003] The utility model aims to overcome the shortcomings of the prior art and provide a coated color cover plate which can obtain the desired color effect at a low cost and avoid ink steps when the cover plate is attached to the optical adhesive layer.

[0004] The purpose of this utility model is achieved through the following technical solutions:

[0005] A coated color cover plate comprises a cover plate body, an optical adhesive layer, an ink layer and a color film layer, wherein the cover plate body comprises a viewing area and a non-viewing area, the optical adhesive layer is relatively attached to the back surface of the cover plate body, the ink layer covers the front surface of the cover plate body, and the color film layer is plated on the ink layer and avoids the viewing area.

[0006] Furthermore, the optical adhesive layer is preferably an OCA adhesive layer.

[0007] Furthermore, the cover body is preferably made of tempered glass or high-aluminum-silicon glass.

[0008] Furthermore, the ink layer includes a first ink layer and a second ink layer, wherein the first ink layer is a black ink layer and the second ink layer is a white ink layer or a color ink layer. The black and white or color ink layers can provide a sharp color contrast, create a rich sense of layering and a three-dimensional effect, and improve adhesion and scratch resistance.

[0009] Furthermore, the first ink layer and the second ink layer are covered from bottom to top on the front side of the cover body by a silk screen printing process.

[0010] Furthermore, the color film layer is coated by vacuum evaporation or magnetron sputtering.

[0011] Furthermore, the color film layer avoids the viewing area by using a film material of PET (polyethylene terephthalate) or PVC (polyvinyl chloride) to cover the viewing area. These film materials have good light transmittance and scratch resistance and can effectively protect the surface of the viewing area.

[0012] The color film layer can avoid the viewing area by plasma process, and the color layer or coating on the viewing area is gradually decomposed by bombarding the surface of the viewing area with a plasma beam.

[0013] Furthermore, the color film layer is an AR film.

[0014] Furthermore, the AR film may be two or more layers, formed by stacking two or more materials selected from SiO, SiO2, Si3N4, TiO, TiO2, Ti2O3, Nb2O3, and Nb2O5.

[0015] Furthermore, the color film layer can be combined with any one or a combination of an anti-fingerprint film, an optical compensation film, and a polarizing film to achieve different functional effects.

[0016] The utility model adopts the method of silk screen printing ink + coating to mix colors on the front side of the cover body. First, black ink is silk screen printed on the front side of the cover body for shading, and then white or color ink is silk screen printed on the black ink to increase the reflectivity of the color. Then, a color film layer is plated on the white or color ink to avoid the viewing area. The back side of the cover body is directly bonded to the optical adhesive layer. Compared with the traditional method of using color ink to mix the required color, the required color of the cover can be obtained at a lower cost, and there is no ink step when the bonding surface of the cover body is bonded to the optical adhesive layer, which is convenient for bonding.

The drawings provide preferred embodiments of the present invention. However, the present invention can be implemented in many different forms and is not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to make the disclosure of the present invention more thoroughly and comprehensively understood.

[0020] It should be noted that the terms "front side", "back side" and similar expressions used in this article are only for illustrative purposes and do not represent the only implementation method.

[0021] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art of the present invention. The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention.

[0022] See also Figure 1 Embodiment 1 of the coated color cover plate includes a cover plate body 1, an optical adhesive layer 2, an ink layer 3 and a color film layer 4. The cover plate body includes a viewing area 11 and a non-viewing area. The optical adhesive layer 2 is relatively attached to the back of the cover plate body 1, the ink layer 3 covers the front of the cover plate body 1, and the color film layer 4 is coated on the ink layer 3 and avoids the viewing area 11.

[0023] In this embodiment, the ink layer 3 and the color film layer 4 are arranged on the front side of the cover body 1, which directly affects the appearance and aesthetics of the product, is easier to be directly seen and perceived by the user, and has a direct impact on the user's interaction and experience; and the optical adhesive layer 2 is directly bonded to the cover body 1, which can ensure that the light is less scattered and reflected during the transmission process between the cover and the display, thereby improving color reproduction and clarity, and the bonding process is relatively simple and does not require complicated equipment or processes, which helps to reduce production costs and improve production efficiency.

[0024] In this embodiment, the optical adhesive layer 2 is preferably an OCA adhesive layer. The good optical properties of the OCA adhesive layer can ensure the accuracy and vividness of the color, and it has excellent weather resistance and chemical resistance. The back of the cover body 1 is directly bonded to it to ensure that the product can maintain stable performance in various harsh environments.

[0025] This embodiment uses the OCA adhesive layer 2 to directly bond with the cover body 1 to avoid the formation of ink steps, thereby preventing the resulting consequences of reduced optical performance, reduced touch performance, and poor bonding. Avoiding the existence of ink steps may cause alignment difficulties during the bonding process, increase debugging time and cost during the production process.

[0026] In this embodiment, the cover body 1 is preferably made of tempered glass or high-alumina-silicon glass.

[0027] In this embodiment, the ink layer 3 includes two layers, wherein the first ink layer 31 is a black ink layer, and the second ink layer 32 is a white ink layer or a color ink layer, and the first ink layer 31 and the second ink layer 32 are covered from bottom to top relative to the front of the cover body 1 by a silk screen printing process. The superposition of black ink + white or color ink can provide a sharp color contrast, create a rich sense of hierarchy and three-dimensional effect, enhance the user's touch and visual experience, and can be used to indicate different functional areas or provide specific marks, such as the background or touch area or the functional area distinction of the identification button.

[0028] In this embodiment, the color film layer 4 is deposited by vacuum evaporation or magnetron sputtering.

[0029] In this embodiment, the color film layer 4 avoids the viewing area 11 by using a material with good light transmittance and scratch resistance, such as PET (polyethylene terephthalate) or PVC (polyvinyl chloride) film to cover the viewing area, aligning the film with the viewing area to ensure that it is completely in contact with the surface of the viewing area, so that the surface of the viewing area is protected by the film, which can effectively prevent damage such as scratches and pollution.

[0030] In another embodiment 2, the ink layer 3 and the color film layer 4 are arranged on the front side of the cover body 1, the color film layer 4 is coated on the ink layer 3 and avoids the viewing area, and the optical adhesive layer 2 is directly attached to the cover body 1, and the color film layer 4 avoids the viewing area 11. The color layer of the viewing area is removed by a plasma process, that is, a plasma beam is used to bombard the surface of the viewing area, so that the color layer or coating thereon is gradually decomposed.

[0031] In this embodiment, the color film layer 4 uses an AR film to enhance the transmittance of the glass, reduce reflection, improve the display effect, and combine with other coating technologies to improve the optical performance and durability of the cover. The AR film is made of two or more materials selected from SiO, SiO2, Si3N4, TiO, TiO2, Ti2O3, Nb2O3, and Nb2O5, stacked to achieve a multi-layer overlapping effect.

[0032] In different implementations of this embodiment, a color film layer + other film layers are used to achieve different functional effects. For example, it can be combined with any one or a combination of an anti-fingerprint film, an optical compensation film, and a polarizing film to improve the screen transmittance while reducing the pollution problem on the screen surface, optimizing the color and contrast performance of the screen, and further improving the clarity and color performance of the image, thereby providing a better visual experience and usage experience.

[0033] In summary, the utility model adopts the method of silk screen printing ink + coating to adjust the color on the front side of the cover body, and the back side of the cover body is directly bonded to the optical adhesive layer, so that the required color of the cover can be obtained at a relatively low cost, and the bonding surface of the cover body is bonded to the optical adhesive layer without an ink step, which is convenient for bonding.

[0034] The above-mentioned embodiments only express several implementation methods of the utility model, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the utility model patent. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model. Therefore, the protection scope of the utility model patent shall be based on the attached claims.
