Description

Technical Field

[0001] The utility model relates to the technical field of display modules, in particular to a display module with optimized surface effects. Background Art

[0002] With the rapid development of the display industry, more and more products are adopting full-laminate technology to achieve near-perfect display effects. However, different application scenarios do not necessarily pursue high-end displays such as TFT or AMOLED with full viewing angles, which are suitable for full-laminate designs. However, due to cost considerations and other factors, many applications do not actually require full-viewing TFT products, but rather traditional black-and-white products or non-full viewing angles. These non-full viewing angle products are generally not suitable for full-laminate designs. These non-full viewing angle displays can degrade in display quality when subjected to external stress (such as ordinary touch or structural stress). In this case, traditional air lamination is necessary. For example, patent application No. CN202322114865.8 discloses a touch screen structure that reduces moisture. The structure includes a TP component, an LCD display, and an adhesive layer for bonding. The adhesive layer is a frame structure used to bond the TP component and the LCD display together. A layer of RTV adhesive is applied to the outside of the adhesive layer of the frame structure. The RTV adhesive cures by absorbing water. The cured RTV adhesive forms a water barrier to prevent moisture from entering the inner part of the screen. This solution builds on existing air-bonding by adding a layer of RTV adhesive to the outside of the adhesive layer. Heat generated by the LCD screen during operation evaporates moisture, which is then absorbed by the RTV adhesive. The absorbed moisture forms a sealed structure, preventing external moisture from entering the display, thereby reducing moisture. However, in traditional air-bonding designs, multiple reflective surfaces exist between the cover plate and the display surface, resulting in strong reflective surfaces that affect the product's aesthetics. Therefore, the present invention addresses this issue by providing a display module with optimized surface finishes. Utility Model Content

[0023] In order to help those skilled in the art better understand the present invention, the following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts should fall within the scope of protection of the present invention.

[0024] As described in the background art, in a traditional air-fit design, there are multiple layers of reflective surfaces between the cover plate and the display screen surface, which results in strong reflection on the exterior and affects the appearance of the product.

[0025] In order to solve this technical problem, the present invention provides a display module with optimized surface effects, which is applied in the field of display modules.

[0026] Specifically, please refer to Figure 1 The display module with optimized surface effect specifically includes a cover plate 1 and a display screen 2 arranged below the cover plate 1, a metal frame 3 is provided on the outside of the display screen 2, the cover plate 1 and the metal frame 3 are bonded and fixed by double-sided adhesive 4, an air layer 5 is formed between the cover plate 1 and the display screen 2, and a first optical film 6 is provided on a surface of the cover plate 1 that is in contact with the air layer 5, and a first optical prism structure 7 is provided on the surface of the first optical film 6.

[0027] The display module with optimized surface effect provided by the present invention increases the diffuse reflection of light and reduces the mirror reflection of the cover plate 1 by arranging a first optical film 6 on the surface of the cover plate 1 and preparing an optical prism structure on the first optical film 6, thereby reducing the re-reflection rate of the incident light, reducing the light entering the human eye, improving the uniformity of the outer surface of the display module, and thus improving the aesthetics of the product.

[0028] In order to enable those skilled in the art to better understand the solution of the present invention, the technical solution in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.

[0029] It should be noted that, in the absence of conflict, the embodiments of the present invention and the features and technical solutions therein can be combined with each other.

[0030] It should be noted that similar reference numerals and letters denote similar items in the following drawings, and therefore, once an item is defined in one drawing, it does not need to be further defined or explained in subsequent drawings.

[0031] Please refer to Figure 1-2, provides a display module with optimized surface effect, which includes a cover plate 1 and a display screen 2 arranged under the cover plate 1, a metal frame 3 is provided on the outside of the display screen 2, which serves as an iron frame, and the cover plate 1 and the metal frame 3 are bonded and fixed by double-sided adhesive 4, and the double-sided adhesive 4 is a rectangular frame structure, and an air layer 5 is formed between the cover plate 1 and the display screen 2, and a surface of the cover plate 1 that is in contact with the air layer 5 is provided with a first optical 6 film 6, and a surface of the first optical film 6 is provided with a first optical prism structure 7, and the first optical prism structure 7 is prepared on a surface of the first optical film 6 close to the display screen 2, and the first optical prism structure 7 increases the diffuse reflection of light and reduces the specular reflection, thereby reducing the re-reflection rate of the incident light.

[0032] In this example, the cover plate 1 is a transparent glass plate. In some embodiments, the bottom surface of the cover plate 1 can be attached to the sensor layer to achieve a touch function.

[0033] The metal frame 3 includes vertical frames 31 and horizontal frames 32. A through-slot corresponding to the air layer 5 is formed in the center of the horizontal frame 32. The cover plate 1 is bonded to the horizontal frame 32. The display screen 2 is an LCD screen, but can also be other screens such as an LED screen. The upper surface of the display screen 2 is bonded to the horizontal frame 32 via foam 8. The thickness of the air layer 5 is the sum of the thicknesses of the horizontal frame 32, the foam 8, and the double-sided adhesive 4.

[0034] A backlight module 9 is also provided below the display screen 2. The display screen 2 includes a lower polarizer 21, a lower glass 22, an upper glass 23 and an upper polarizer 24 stacked in sequence from bottom to top. The lower polarizer 21 is glued and fixed to the backlight module 9. The backlight module 9 includes a bottom frame, a light guide plate and a light source for providing backlight for the display screen 2. Some backlight modules 9 also include optical film materials for processing the light guided from the light guide plate.

[0035] One end of the lower glass 22 extends out of the upper glass 23 to form a single-layer structure. The main screen FPC10 is bound to the single-layer structure of the lower glass 22, and a chip IC11 is provided on the single-layer structure of the lower glass 22. The display screen 2 and the backlight module 9 are controlled by the chip IC11 and the main screen FPC10.

[0036] The display module with optimized surface effect provided in Example 1 is further optimized, specifically, Figure 3 As shown, a second optical film 12 is provided on a surface of the display screen 2 close to the cover plate 1, and a second optical prism structure 13 is provided on the surface of the second optical film 12. After the light is diffusely reflected by the first optical prism structure 7 on the first optical film 6, a large amount of light will still be reflected back on the upper surface of the display screen 2, and enter the human eye after passing through the first optical film 6 at the bottom of the cover plate 1. The second optical film 12 can further diffusely reflect the light, thereby further reducing the light entering the human eye.

[0037] The planar dimensions of the second optical film 12 are consistent with those of the upper polarizer 24. The planar dimensions of the first optical film 6 and the second optical film 12 are both larger than the planar dimensions of the air layer 5, thereby ensuring that the reflected light can be completely diffusely reflected. The first optical prism structure 7 and the second optical prism structure 13 are both regular pyramids distributed in a matrix. The regular pyramids are regular square pyramids or regular hexagonal pyramids. The matrix distribution spacing of the regular pyramids is consistent with the side length of the base of the regular pyramids, so that the bases of adjacent regular pyramids intersect together, allowing the regular pyramids to be laid flat on the optical film. The prism structure is prepared by hot embossing or photolithography.

[0038] The display module with optimized surface effect provided in Example 2 is further optimized. Specifically, Figure 3 、 4 As shown, the first optical prism structure 7 and the second optical prism structure 13 are respectively arranged on a surface of the first optical film 6 and the second optical film 12 close to each other. After the light is diffusely reflected by the first optical film 6, the remaining light enters the second optical film 12 and can be diffusely reflected again, which can reduce the light entering the display screen 2, so that the light is returned back and forth between the first optical film 6 and the second optical film 12, thereby minimizing the amount of light emitted from the cover 1 and entering the human eye.

[0039] The working principle of the display module with optimized surface effect provided by the present invention is as follows: by arranging a first optical film 6 on the surface of the cover plate 1, arranging a second optical film 12 on the upper surface of the display screen 2, and preparing an optical prism structure on the first optical film 6 and the second optical film 12, the diffuse reflection of light is increased, the mirror reflection of the cover plate 1 is reduced, and thus the re-reflectivity of the incident light is reduced. After multiple diffuse reflections by the upper and lower film layers, the light entering the human eye is reduced, the uniformity of the outer surface of the display module is improved, and thus the aesthetics of the product is improved.
