[0029] Embodiment 1

[0030] like Figures 1 to 3As shown, the utility model provides a display module film alignment structure, including a film touch layer 2, with protruding positions provided at the relative positions of the two side edges, and the protruding positions are provided with a first magnetic area 201;

[0031] The display screen 1 is disposed on the lower surface of the film touch layer 2, and the film touch layer 2 and the display screen 1 are bonded together via an optical adhesive layer;

[0032] The housing 3 is disposed on the upper surface of the film touch layer 2 and has a second magnetic region 301 corresponding to the first magnetic region 201 of the film touch layer 2;

[0033] The film touch layer 2 and the housing 3 are quickly assembled and combined through magnetic adsorption of the first magnetic area 201 and the second magnetic area 301 .

[0034] Wherein, the film touch layer 2 and the display screen 1 are circular.

[0035] In the present application, two protruding positions are made on the left and right shapes of the film touch layer 2, and circular or cross-shaped magnetic areas are designed on the protruding positions. At the same time, corresponding magnetic areas are also designed on the client shell 3. By means of magnetic attraction, when the shell 3 is placed on the surface of the film touch layer 2, there is no need to observe the alignment carefully. Only a certain angle of rotation is required. At this time, the first magnetic area 201 and the second magnetic area 301 are automatically adsorbed to complete the assembly combination, which can reduce the rotational tolerance generated when the customer installs the machine, and also facilitate the operator to complete the assembly combination more quickly, and the magnetic attraction on the protruding position to the corresponding position of the shell improves product quality and production efficiency.

[0036] Furthermore, the film touch layer 2 and the display screen 1 are bonded together by an optical adhesive layer; the film touch layer 2 and the display screen 1 are preferably but not limited to being bonded together by a transparent optical adhesive layer such as OCA adhesive and solid adhesive, or can be bonded together by a frame adhesive such as a frame adhesive;

[0037] In another preferred embodiment of the present embodiment, the upper surface of the film touch layer 2 is sequentially stacked with an anti-glare AG layer and an anti-reflection AR layer, which are not shown in the figure. The anti-glare AG layer can be an anti-glare AG coating, which forms micro-concave and convex on the surface of the film touch layer 2 to scatter external light and reduce direct reflection, thereby reducing reflected light. The anti-reflection AR layer can be an anti-reflection AR coating, which alternately coats a material with a high refractive index and a material with a low refractive index on the surface, which can directly reduce the reflected visible light with various wavelength bands of 350nm to 750nm. Furthermore, in order to prevent fingerprints from being generated on the touch screen, an anti-fingerprint AF layer is also stacked on the touch screen 2. Specifically, the anti-fingerprint AF layer is formed on the anti-reflection AR layer.

[0038] Furthermore, the first magnetic region 201 and the second magnetic region 301 are circular or cross-shaped.

[0039] Furthermore, the first magnetic region 201 and the second magnetic region 301 are adsorbed by magnetic ink or other magnetic materials.

[0040] It should be noted that magnetic ink is a special ink that contains iron oxide or other magnetic materials to make it magnetic. This ink has good magnetic adsorption properties and can be adsorbed on metal or other magnetic surfaces to achieve the alignment and fixing function. The production process of magnetic ink is relatively complicated. It is necessary to fully mix the magnetic material with the ink base material and process and adjust it through special processes to ensure that the ink has appropriate viscosity and fluidity. A well-made magnetic ink must not only have good magnetic adsorption properties, but also have good printing properties, and can be printed smoothly and evenly on various printing equipment.

[0041] Embodiment 2

[0042] like Figure 4 As shown, the display screen 1 includes an upper polarizer 101, an upper glass 102, a lower glass 103 and a lower polarizer 104 stacked in sequence. The polarizer has a fixed polarization axis, and only allows light with a vibration direction consistent with the polarization direction to pass through, and absorbs light with a vibration direction perpendicular to the polarization axis, and is used to convert natural light without polarization into polarized light, allowing light with a direction perpendicular to the electric field to pass through, so that the liquid crystal display panel can display images normally.

[0043] In this embodiment, liquid crystal material is filled between the upper glass 102 and the lower glass 103. Among them, the liquid crystal is a special substance that has properties between liquid and solid. The liquid crystal molecules are arranged in an orderly manner when there is no external influence, but when subjected to external effects such as electric field, temperature or pressure, the liquid crystal molecules will change their arrangement structure, thereby producing different optical properties. Liquid crystal materials are usually composed of organic molecules or polymers, which have a long shape so that they can form a specific arrangement structure in the liquid crystal state. According to the arrangement of liquid crystal molecules, liquid crystals can be divided into various types, including nematic liquid crystals, twisted nematic liquid crystals, helical liquid crystals, etc. Liquid crystal materials are widely used in display technology, especially in liquid crystal display screens. In liquid crystal display screens, liquid crystal materials are filled between two pieces of glass to form a liquid crystal layer. When an electric field is applied, the arrangement structure of the liquid crystal molecules will change, thereby changing the polarization state of light passing through the liquid crystal layer to achieve image display.

[0044] Embodiment 3

[0045] like Figure 5As shown, a backlight module 4 is disposed on the lower surface of the display screen 1 , and the backlight module 4 is located on a side of the lower polarizer 104 away from the lower glass 103 .

[0046] Furthermore, the backlight module 4 includes a lower frame 401 , a reflective sheet 402 , a light guide plate 403 and an optical film group 404 which are sequentially stacked from bottom to top.

[0047] Among them, the lower frame 401 is made of integrated injection molding of glue and iron, which is used to fix, support and protect the various components of the backlight module 4; the reflective sheet 402 is located on the inner side of the lower frame 401, which is used to reflect light and improve the backlight effect; the light guide plate 403 is located above the reflective sheet 402, which is used to evenly transmit light to the surface of the entire backlight module 4; the optical module is located above the light guide plate 403 to diffuse light, enhance the backlight effect, enhance the light brightness, and make the display effect clearer and brighter.

[0048] Furthermore, the film touch layer 2 is provided with a second FPC 21 , and the display screen 1 is provided with a first FPC 11 .

[0049] Furthermore, the second FPC 21 is overlapped with the first FPC 11 .

[0050] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the embodiments of the utility model rather than to limit them. Although the embodiments of the utility model are described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the embodiments of the utility model can still be modified or replaced by equivalents, and these modifications or equivalent replacements cannot cause the modified technical solutions to deviate from the scope of the technical solutions of the embodiments of the utility model.
