Description

[0002] As competition in the smartphone market becomes increasingly fierce, full-screen design has become a key trend to improve user experience. Full-screen design not only requires maximizing the screen-to-body ratio, but also takes into account lightness, portability and aesthetics. In order to achieve this design goal, the glass frame of the integrated touch module is constantly being made narrower, and the structure of the backlight module is also facing challenges.

[0003] In the traditional backlight module design, the light shielding glue is used to isolate the backlight from the non-display area of ​​the display screen to reduce light leakage. However, as the frame narrows, the width of the light shielding glue is also reduced accordingly, resulting in a smaller bonding area with the polarizer under the display screen and a lower bonding strength. The direct problem caused by this structural change is that when the whole machine is undergoing reliability testing, such as in environments such as vibration and roller drop, the backlight and the display screen are easily separated, which not only affects the durability of the product, but also reduces user satisfaction. Therefore, we have made improvements to this and proposed an integrated touch module structure. Utility Model Content

[0024] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those generally understood by those skilled in the art to which the present invention belongs; the terms used in the specification of the application herein are only for the purpose of describing specific embodiments and are not intended to limit the present invention. Reference to "embodiments" herein means that specific features, structures, or characteristics described in conjunction with the embodiments may be included in at least one embodiment of the present invention. The appearance of this phrase in various locations in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive with other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0025] As described in the background technology, in the traditional backlight module design, the light-shielding glue is used to isolate the backlight from the non-display area of ​​the display screen to reduce light leakage. However, as the frame becomes narrower, the width of the light-shielding glue is also reduced accordingly, resulting in a reduction in the bonding area with the polarizer under the display screen and a decrease in the bonding strength. The direct problem caused by this structural change is that when the whole machine is subjected to reliability testing, such as in environments such as vibration and roller falling, the backlight and the display screen are very likely to separate, which not only affects the durability of the product, but also reduces user satisfaction.

[0026] In order to solve this technical problem, the utility model provides an integrated touch module structure.

[0027] Specifically, please refer to Figure 1-Figure 4 , the integrated touch module structure specifically includes:

[0028] The display screen assembly 1 and the backlight assembly 3, the backlight assembly 3 includes a rubber frame 301, the rubber frame 301 extends to the outside of the display screen assembly 1, the display screen assembly 1 includes a lower polarizer body 101, a shading glue body 2 is bonded between the lower polarizer body 101 and the rubber frame 301, and the outer sides of the shading glue body 2, the rubber frame 301 and the lower polarizer body 101 are flush.

[0029] The integrated touch module structure provided by the utility model extends the glue frame 301 to the outside of the display screen assembly 1, and the outer sides of the light-shielding glue body 2, the glue frame 301 and the lower polarizer body 101 are flush, so that the outer dimensions of the lower polarizer body 101 are increased, and the bonding area between the light-shielding glue body 2 and the display screen assembly 1 is effectively increased, thereby significantly improving the bonding firmness, reducing the separation problem of the backlight assembly 3 and the display screen assembly 1 in the reliability test, thereby improving the durability of the product and user satisfaction.

[0030] In order to enable those skilled in the art to better understand the solution of the utility model, the technical solution in the embodiments of the utility model will be clearly and completely described below in conjunction with the accompanying drawings.

[0031] It should be noted that, in the absence of conflict, the embodiments of the present invention and the features and technical solutions in the embodiments may be combined with each other.

[0032] 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, further definition and explanation thereof is not required in subsequent drawings.

[0033] Embodiment 1 of the integrated touch module structure of the utility model

[0034] Please refer to Figure 1-Figure 4 The integrated touch module structure of the utility model includes: a display screen assembly 1 and a backlight assembly 3, the backlight assembly 3 includes a glue frame 301, the glue frame 301 extends to the outside of the display screen assembly 1, the display screen assembly 1 includes a lower polarizer body 101, a shading glue body 2 is bonded between the lower polarizer body 101 and the glue frame 301, and the outer sides of the shading glue body 2, the glue frame 301 and the lower polarizer body 101 are flush. In this application, the outer dimensions of the lower polarizer body 101 are increased by extending the glue frame 301 to the outside of the display screen assembly 1, and the shading glue body 2, the glue frame 301 and the outer sides of the lower polarizer body 101 are flush, so that the bonding area of ​​the shading glue body 2 and the display screen assembly 1 is effectively increased, thereby significantly improving the bonding firmness, reducing the separation problem of the backlight assembly 3 and the display screen assembly 1 in the reliability test, thereby improving the durability of the product and user satisfaction.

[0035] Further, such as Figure 4 As shown, the display screen assembly 1 also includes a display assembly, a cover plate body 4 is arranged on one side of the display assembly, the display assembly is arranged on the side of the lower polarizer body 101 away from the light shielding glue body 2, and glue 5 is filled between the display assembly, the cover plate body 4 and the lower polarizer body 101;

[0036] Smartphones have increasingly rich functions. One of them is to sense the intensity of ambient light through the light-sensing holes on the cover plate to automatically adjust the screen brightness and improve the user experience. However, in actual applications, the light emitted by the glass may interfere with the normal operation of the light-sensing hole sensing device, resulting in inaccurate screen brightness adjustment. To solve this problem, the traditional method is to stick a piece of shading paper on the upper end of the backlight to shield the interfering light. However, the introduction of shading paper brings new problems: its thickness increases the space requirement of the whole machine, and the casing design needs to make corresponding concessions, which not only limits the compact design of the whole machine, but also may affect the structural strength of the whole machine, reducing the overall performance of the product;

[0037] To solve the above problem, the present application provides glue 5, and the color of glue 5 is black. The black glue 5 can block the light emitted by the display screen assembly 1 and the backlight assembly 3, and can also increase the fixation of the cover plate body 4 and the display screen assembly 1. The thickness of the glue 5 is flush with the top edge of the glue frame 301 or does not exceed the top edge of the glue frame 301. The glue 5 can prevent light leakage at the position of the photosensitive hole and does not affect the product's external dimensions.

[0038] Embodiment 2 of the integrated touch module structure of the utility model

[0039] The utility model further integrates the touch control module structure, such as Figure 1 , Figure 2 and Figure 4 As shown, the display assembly includes an upper glass body 103, a side of the upper glass body 103 close to the cover body 4 is connected to an upper polarizer 104, a side of the upper polarizer 104 away from the upper glass body 103 is connected to a bonding adhesive 105, the bonding adhesive 105 is bonded to the cover body 4, the bonding adhesive 105 is used to connect the upper polarizer 104 and the cover body 4 together, that is, to realize the connection between the display screen assembly 1 and the cover body 4, and the bonding adhesive 105 adopts transparent OCA optical adhesive;

[0040] Transparent OCA optical adhesive is a special adhesive used to bond transparent optical components. It belongs to the category of pressure-sensitive adhesive. OCA optical adhesive has extremely high transparency, which can ensure that the bonded optical components do not produce obvious color difference or obstruction visually. Its light transmittance is extremely high, generally required to be above 90%, which ensures that the optical components can still maintain good optical properties after bonding. OCA optical adhesive can form a stable bonding layer after curing, ensuring that the bonded optical components are not easy to fall off during use. OCA optical adhesive can be cured at room temperature or medium temperature, and has small curing shrinkage, which is conducive to maintaining the flatness and optical properties of the bonding surface.

[0041] The upper polarizer 104 is mainly used to analyze the polarized light after being electrically modulated by the liquid crystal. The liquid crystal layer will modulate the polarization state of the incident light according to the electrical signal. The upper polarizer 104 is responsible for analyzing these modulated polarized lights, and by controlling the direction and intensity of the transmitted light, it produces a contrast between light and dark, thereby forming the display screen we see. The lower polarizer body 101 cooperates with the upper polarizer 104. The upper polarizer 104 is an indispensable part of forming the display image. It ensures that only polarized light in a specific direction can pass through, thereby producing a clear image.

[0042] The main function of the lower polarizer body 101 is to convert the non-polarized light emitted by the backlight assembly 3 into polarized light in a specific direction. The light emitted by the backlight assembly 3 is originally non-polarized light vibrating in all directions. After passing through the lower polarizer body 101, only the light parallel to the transmission axis of the lower polarizer body 101 can pass through and become polarized light.

[0043] Further, such as Figure 1-Figure 2 As shown, a side of the upper glass body 103 away from the cover plate body 4 is connected to the lower glass body 102 , and the lower glass body 102 is connected to the lower polarizer body 101 .

[0044] The lower glass body 102 and the upper glass body 103 serve as the basic structure of the display screen assembly 1 and provide stable support for various components. At the same time, they also play a role in protecting the internal components from external physical damage.

[0045] Further, such as Figure 1-Figure 2 As shown, the glue 5 is connected between the cover plate body 4 and the side of the lower polarizer body 101 that are close to each other, and the end surfaces of the bonding glue 105 , the upper polarizer 104 , the upper glass body 103 and the lower glass body 102 are all connected to the glue 5 .

[0046] Embodiment 3 of the integrated touch module structure of the utility model

[0047] The utility model further integrates the touch control module structure, such as Figure 1 , Figure 2 and Figure 4As shown, a backlight iron frame 302 is provided on one side of the glue frame 301 away from the shading glue body 2, and a backlight part is provided between the backlight iron frame 302 and the shading glue body 2. The backlight iron frame 302 mainly plays a supporting and protective role. Specifically, the backlight iron frame 302 is used to enhance the hardness of the backlight assembly 3 and protect the display screen assembly 1 from being easily broken. The backlight iron frame 302 is used to resist external impact and extrusion, thereby extending the service life of the entire module. In addition, the backlight iron frame 302 also has a certain heat dissipation function, which helps to reduce the heat generated by the backlight assembly 3 during operation and improve the stability and reliability of the equipment.

[0048] Further, such as Figure 4 As shown, the backlight part includes a light source component arranged between the backlight iron frame 302 and the glue frame 301 and an auxiliary component arranged between the light source component and the light shielding glue body 2.

[0049] Further, such as Figure 4 As shown, the light source component includes a light guide plate 306, and an LED lamp bead 308 is arranged on one side of the light guide plate 306. When the LED lamp bead 308 is lit, it will illuminate the entire display screen assembly 1 to provide a clear visual experience for the viewer. The main function of the light guide plate 306 is to convert the point light source emitted by the LED lamp bead 308 into a surface light source to provide uniform and stable light source support.

[0050] Further, such as Figure 4 As shown, a reflective film 307 is connected to the side of the light guide plate 306 close to the backlight iron frame 302, and the reflective film 307 is connected to the backlight iron frame 302. A diffusion film 305 is connected to the side of the light guide plate 306 away from the reflective film 307. The reflective film 307 can reflect light and increase the reflectivity of light, thereby improving the brightness and contrast of the liquid crystal display. In a strong light environment, the reflective function of the reflective film 307 can make the picture clearer and brighter, thereby improving the viewing effect.

[0051] Further, such as Figure 4 As shown, the auxiliary part includes a lower brightness enhancement sheet 304 connected to a diffusion film 305, and an upper brightness enhancement sheet 303 is connected to the side of the lower brightness enhancement sheet 304 away from the diffusion film 305. The upper brightness enhancement sheet 303 is bonded to the light-shielding adhesive body 2. The main function of the diffusion film 305 is to scatter light evenly and improve optical performance. If the light is uneven, bright spots or dark areas will be formed. The diffusion film 305 uses its internal microstructure or particles to scatter the light multiple times when passing through, thereby achieving uniform distribution of light on the entire plane. The uniform light distribution helps to improve the brightness and color uniformity of the display, making the picture clearer and more comfortable. At the same time, the diffusion film 305 can also reduce reflected light and glare, and improve the contrast and clarity of the display.

[0052] The upper brightness enhancement sheet 303 gathers the light toward the front direction by utilizing the diffuse reflection of the light source and the focusing effect of the prism, thereby significantly improving the brightness of the display, which is particularly important for using the display device in a dark environment; the upper brightness enhancement sheet 303 can also reduce the scattering and reflection of light to a certain extent, improve the contrast of the display, and make the picture clearer and sharper;

[0053] Different from the upper brightness enhancement sheet 303, the main function of the lower brightness enhancement sheet 304 is to diffuse the light evenly. The lower brightness enhancement sheet 304 can ensure that the light has been fully diffused and homogenized before reaching the upper brightness enhancement sheet 303, thereby providing a good foundation for subsequent optical processing. Through its special microstructure or coating design, the lower brightness enhancement sheet 304 can also enhance the backlight effect to a certain extent, making the light softer and more uniform.
