[0001] The utility model relates to the technical field of integrated touch modules, in particular to an integrated touch module structure. Background Art
[0002] Currently, mobile phones adjust the brightness of the display screen by sensing the brightness of the ambient light through photosensitive holes. During the actual processing and production process, some factories will stick a light-diffusion film on the photosensitive holes of the cover plate. The light-diffusion film has the function of diffusing light, causing the light to scatter through the surface, thereby achieving a light-diffusion effect. However, this light-diffusion film requires additional labor, and the light-diffusion film is small in size and difficult to attach, which affects production efficiency and production yield. For this reason, this patent provides an integrated touch module structure. Utility Model Content
[0003] Based on this, it is necessary to provide an integrated touch module structure to address the above technical problems, and to arrange a light-distributing film on the camera protective film, thereby increasing its overall attachment area and facilitating the removal during attachment, thereby completing the attachment protection of the camera film and simultaneously realizing the alignment and attachment of the light-distributing film.
[0004] In order to solve the above technical problems, the utility model adopts the following technical solutions:

[0007] A backlight, which is attached to the back of the cover plate to form a touch module;
[0008] A protective film, which is attached to the cover plate and is used to protect the camera;
[0009] Wherein, a light-distributing film is also provided on the protective film, and when the protective film is attached to the cover plate, the light-distributing film covers the light-sensing hole and is attached thereto.
[0010] Furthermore, the protective film comprises a main film body, the main film body has an extension portion extending in the direction of the light sensing hole, and the light-homogenizing film is arranged on the extension portion.
[0011] Furthermore, the main film body has a tear handle extending toward the outer side of the cover plate for tearing off the protective film.
[0012] Furthermore, the adhesive surfaces of the main film body and the extension part are both coated with an adhesive layer 1, and the light-homogenizing film is adhered to the extension part through the adhesive layer 1.
[0013] Furthermore, a second adhesive layer is coated on a side of the light-homogenizing film away from the first adhesive layer, and the light-homogenizing film is adhered to the top of the photosensitive hole through the second adhesive layer to diffuse light;
[0014] Wherein, the viscosity of the adhesive layer 1 is less than the viscosity of the adhesive layer 2.
[0015] Furthermore, a white oil alignment line is provided between the light sensing hole and the emission hole, and the end of the upper extension portion of the protective film is arranged corresponding to the white oil alignment line. The protective film is attached to the light averaging film with the assistance of the white oil alignment line.
[0016] Furthermore, a force reducing groove is provided on the surface of the extension portion, and the edge of the light homogenizing film is partially exposed through the force reducing groove.
[0017] Furthermore, the inner sides of the stress reducing grooves are punched with stress dispersing chamfers.
[0018] Furthermore, an auxiliary groove is formed on the surface of the extension portion, and two auxiliary grooves are respectively located on both sides of the extension portion and are connected to the corresponding force reducing grooves.
[0019] Furthermore, a crease line is provided at the connection between the main film body and the tear handle portion, and the tear handle portion can be folded along the crease line.
[0020] Compared with the prior art, the utility model has the following beneficial effects:

In the process of attaching the main film body to the camera, the light-distributing film thereon is also attached synchronously, which improves the efficiency of attachment.
[0022] At the same time, due to the different viscosities of the adhesive layer 1 and the adhesive layer 2, after the camera film is subsequently torn off, the light-homogenizing film can still cover the light-sensing hole to form a light-homogenizing effect, thereby achieving its practical application;
[0023] In addition, due to the opening of the force reduction groove and the auxiliary groove, in some special environments, when the light-dispersing film and the protective film stick together and are difficult to remove, auxiliary pressing can be performed in the auxiliary groove to prevent the light-dispersing film from warping and falling off.

[0037] In order to enable those skilled in the art to better understand the solution of the utility model, the technical solution in the embodiment of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiment of the utility model. Obviously, the described embodiment is only a part of the embodiment of the utility model, not all of the embodiments. Based on the embodiment of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the utility model.
[0038] As mentioned in the background technology, currently mobile phones adjust the brightness of the display screen by sensing the brightness of the ambient light through the photosensitive holes. During the actual processing and production process, some factories will stick a light-diffusion film on the photosensitive holes of the cover plate. The light-diffusion film has the function of diffusing light, so that the light is scattered through the surface, thereby achieving a light-diffusion effect. However, this light-diffusion film requires additional labor, and the light-diffusion film is small in size and is not easy to attach.
[0039] In order to solve this technical problem, the utility model provides an integrated touch module structure, which is applied to the integrated touch module.
[0040] Specifically, please refer to Figure 1-Figure 7 , the integrated touch module structure specifically includes:
[0041] A cover plate 1 is provided with a camera 11 at the center of the top of the cover plate 1, and a light sensing hole 12 and a transmitting hole 13 are also provided on one side of the camera 11;
[0042] A backlight 2, which is attached to the back of the cover plate 1 and together forms a touch module;
[0043] A protective film 3, which is attached to the cover plate 1 and is used to protect the camera 11;
[0044] A light-distributing film 4 is also provided on the protective film 3 . When the protective film 3 is attached to the cover plate 1 , the light-distributing film 4 covers the light-sensing holes 12 and is attached thereto.
[0045] The integrated touch module structure provided by the utility model is extended on the basis of the traditional camera protective film so that it can cover the position of the light sensing hole 12, and the light-distributing film 4 is arranged on the protective film 3 to increase the area of the overall film body, which is convenient for taking and attaching. In the process of attaching the main film body 31 to the camera 11, the light-distributing film 4 thereon is also synchronously pasted, thereby improving the efficiency of attachment.
[0046] 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.
[0047] 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.
[0048] 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.
[0049] Example 1
[0050] Please refer to Figure 1-Figure 7 An integrated touch module structure includes a cover plate 1, a camera 11 is provided at the center of the top of the cover plate 1, and a light sensing hole 12 and an emission hole 13 are also provided on one side of the camera 11; a backlight 2, which is attached to the back of the cover plate 1 to form a touch module together; a protective film 3, which is attached to the cover plate 1 to protect the camera 11, wherein a light-dispersing film 4 is also provided on the protective film 3, and when the protective film 3 is attached to the cover plate 1, the light-dispersing film 4 covers the light sensing hole 12 and is attached.
[0051] The purpose of attaching the protective film 3 on the camera 11 is to ensure the cleanliness of the surface of the camera hole and prevent scratches when the product is shipped. When the integrated touch module structure needs to be assembled with other components later, the protective film 3 can be torn off to expose the camera for functional use. The purpose of attaching the light-dispersing film 4 is to diffuse the light and scatter it through the surface, thereby achieving a light-dispersing effect. Therefore, it is continuously attached to the light-sensing hole 12 for use during subsequent assembly.
[0052] Please refer to Figure 3 , 4 The protective film 3 includes a main film body 31, the main film body 31 has an extension portion 32 extending toward the light sensing hole 12, and the light homogenizing film 4 is disposed on the extension portion 32;
[0053] The adhesive surfaces of the main film body 31 and the extension part 32 are coated with an adhesive layer 1 34, and the light homogenizing film 4 is adhered to the extension part 32 through the adhesive layer 1 34;
[0054] The light-homogenizing film 4 is coated with a second adhesive layer 41 on one side away from the first adhesive layer 34. The light-homogenizing film 4 is attached to the photosensitive hole 12 through the second adhesive layer 41 to diffuse the light.
[0055] Before the protective film 3 and the light-homogenizing film 4 are actually attached, the light-homogenizing film 4 is attached to the protective film 3 through the adhesive layer 1 34 on the protective film 3, and the attachment position is aligned with the position of the photosensitive hole 12. When the protective film 3 is attached to the cover plate 1 through the adhesive layer 1 34 to protect the camera 11, the light-homogenizing film 4 attached to the protective film 3 is also synchronously attached to the position of the photosensitive hole 12 on the cover plate 1 through the adhesive layer 2 41 thereon. Since the overall design size of the protective film 3 is larger than that of the light-homogenizing film 4, the method of attaching the light-homogenizing film 4 through the protective film 3 is easier than directly taking the light-homogenizing film 4 to attach it, and it is easier to attach the position accurately;
[0056] At the same time, since the protective film 3 and the light-distributing film 4 are connected as one, a single film-attaching operation can not only realize the attachment protection of the camera 11, but also complete the attachment of the light-distributing film 4 required for light-distributing the light-sensing hole 12, thereby effectively improving the efficiency of the attachment operation;
[0057] In order to protect the camera 11 from dust during the assembly and transportation of the module, the protective film 3 is pasted, and the protective film 3 needs to be torn off during the subsequent pasting. Therefore, the viscosity of the adhesive layer 1 34 is designed to be smaller than the viscosity of the adhesive layer 2 41;
[0058] In this way, after the protective film 3 is subsequently torn off, since the viscosity of the adhesive layer 1 34 on the protective film 3 is less than that of the adhesive layer 2 41, the light-homogenizing film 4 can be stably adhered to the photosensitive hole 12 through the adhesive layer 2 41, and the protective film 3 can be easily torn off independently;
[0059] As a further optimization of this embodiment, the main film body 31 has a tear handle 33 extending toward the outside of the cover plate 1. Figure 3 The tear handle 33 shown extends outside the cover plate 1, so when the protective film 3 needs to be removed, the entire protective film 3 can be separated by pulling the tear handle 33 from the outside, which facilitates the tearing operation;
[0060] A crease line 35 is provided at the connection between the main film body 31 and the tear handle portion 33, and the tear handle portion 33 can be folded along the crease line 35. Through the setting of the crease line 35, after the integrated touch module structure is attached with the protective film 3, the tear handle portion 33 can be folded along the crease line 35 and flipped on the protective film 3, thereby reducing its contact with the outside world and causing the protective film 3 to fall off, which is beneficial to the stability of the protective film 3 after adhesion.
[0061] Example 2
[0062] The integrated touch module structure provided in Example 1 is further optimized. Specifically, Figure 4 As shown, a white oil alignment line 14 is provided between the light sensing hole 12 and the emission hole 13, and the end of the extension portion 32 on the protective film 3 is arranged corresponding to the white oil alignment line 14, and the protective film 3 assists the light homogenizing film 4 to be attached through the white oil alignment line 14;
[0063] like Figure 3 , Figure 4 and Figure 5 As shown, the end of the homogenizing film 4 is flush with the end of the extension portion 32, so the white oil alignment line 14 preset on the cover plate 1 can be used as a reference for position alignment when the protective film 3 is attached, thereby ensuring the accuracy of the attachment of the protective film 3 and the homogenizing film 4;
[0064] Since the white oil alignment line 14 is screen-printed on the back of the cover plate 1 , it will be hidden inside during subsequent assembly and cannot be observed on the front of the cover plate 1 , thus not affecting the overall aesthetics.
[0065] Example 3
[0066] The integrated touch module structure provided in Example 1 or 2 is further optimized, such as Figure 6 and Figure 7As shown, in Example 1, the viscosity of the second adhesive layer 41 is designed to be greater than the strength of the first adhesive layer 34 to ensure that when the protective film 3 is torn off, the main film body 31 can be separated independently. However, in some special working conditions or in the case of partial tearing, when the main film body 31 is torn off, it is still possible to cause the homogenizing film 4 to be associated, so the force reduction groove 320 is set;
[0067] A stress reducing groove 320 is formed on the surface of the extension portion 32, and the edge of the light homogenizing film 4 is partially exposed through the stress reducing groove 320. A stress dispersing chamfer 321 is punched on the inner side of the stress reducing groove 320.
[0068] like Figure 7 As shown, since the force reduction groove 320 is provided, the edge of the end of the light homogenizing film 4 pasted below the protective film 3 is exposed. Therefore, when the protective film 3 is actually torn off from the left side to the right side, when the edge of the light homogenizing film 4 is torn off, the protective film 3 can reduce the possibility of the light homogenizing film 4 being lifted up at the edge, and finally the light homogenizing film 4 is torn off as a whole, thereby improving the stability of the light homogenizing film 4 in the torn state;
[0069] At the same time, through the design of the stress dispersing chamfer 321, the connection strength around the stress reducing groove 320 on the extension part 32 can be ensured during tearing, reducing the possibility of tearing fracture, so that the stress can be better concentrated on the extension part 32 area covered on the homogenizing film 4 to achieve tearing;
[0070] As a further optimization of this embodiment, the surface of the extension portion 32 is further provided with auxiliary grooves 322 , and the two auxiliary grooves 322 are respectively located on both sides of the extension portion 32 and communicate with the corresponding force reducing grooves 320 ;
[0071] If after the above-mentioned force reducing groove 320 is set, when the protective film 3 is torn off, the edge of a certain light-distributing film 4 still causes warping and is easy to cause the entire film to fall off, at this time, auxiliary pressing can be performed in the auxiliary groove 322 to manually press the edge of the light-distributing film 4 to ensure the stability of the tearing direction, thereby preventing the light-distributing film 4 from falling off.
[0072] The use process of the integrated touch module structure provided by the utility model is as follows: the protective film 3 with the light-homogenizing film 4 is attached to the cover plate 1 by aligning it with the white oil alignment line 14. After attachment, the main film body 31 protects the camera 11, and the light-homogenizing film 4 disperses the light of the photosensitive hole 12. During the subsequent further assembly, the protective film 3 can be torn off independently through the tear handle 33. Since the adhesive strength of the adhesive layer 2 41 is greater than the adhesive strength of the adhesive layer 1 34, the light-homogenizing film 4 is still retained on the photosensitive hole 12 for use.
[0073] In the present invention, unless otherwise clearly specified and limited, the terms "installed", "connected", "connected", "fixed" and the like should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral one; it can be a mechanical connection, an electrical connection, or communication with each other; it can be a direct connection, or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements, unless otherwise clearly defined.
