Detailed Implementation

[0045] The embodiments of this application will now be clearly and completely described with reference to the accompanying drawings. Those skilled in the art will recognize that, with technological advancements and the emergence of new scenarios, the technical solutions provided in the embodiments of this application are equally applicable to similar technical problems.

[0046] Touch modules in add-on touch display devices are typically single-glass structures. Depending on the conductive materials used for the touch electrodes, touch modules mainly include two structures: OGS (One Glass Solution) and OGM (One Glass Metal Mesh). OGS uses ITO (Indium Tin Oxide, a transparent conductive material) as the touch electrodes, while OGM uses a metal mesh.

[0047] With the widespread application of OLED displays, the use of single-glass OGS (Optical Glass System) touch modules is increasing to address issues such as gray spots and moiré patterns in external touch display devices formed by combining touch modules with OLED displays. OGS touch modules can be fabricated using photolithography, where patterned ITO is processed on a glass substrate to form touch electrodes. OGS touch modules typically require an anti-aliasing layer, which can affect the transmittance at the camera aperture, reducing the amount of light received by the camera and thus impacting image quality.

[0048] The OGS structure touch module is not limited to photolithography; it can also be fabricated using other processes, such as laser etching, screen printing, or magnetron reduction. This application does not limit the specific process.

[0049] To address the aforementioned issues, a common solution is to use a GF2 (One Glass Metal Mesh) touch module, whose core structure achieves touch functionality through a combination of multiple thin films and a glass substrate. This solution requires special treatment at the camera location to ensure transmittance at that location is not affected. The drawback of this solution is that the GF2 structure requires additional thin film layers, significantly impacting the thickness of the touch display module and its overall optical characteristics, making it difficult to pass HDR (High Dynamic Range) tests for OLED displays.

[0050] In view of this, embodiments of this application provide a touch display device, including a display module and a touch module, wherein the touch module is located on the display side of the display module, and the touch module includes:

[0051] Transparent substrate;

[0052] Touch components located on one side surface of a transparent substrate;

[0053] An anti-reflection layer located on the side of the touch component facing away from the transparent substrate;

[0054] The anti-reflection layer is equipped with a light-transmitting port, which is positioned opposite to the light-collecting port of the camera on the light-emitting side of the display module.

[0055] In this embodiment, the touch display device provides a light-transmitting port in the anti-reflection layer of the touch module, which is opposite to the light-collecting port of the camera, in order to avoid the impact of the anti-reflection layer on the light-collecting effect of the camera, thereby improving the imaging quality of the camera.

[0056] Moreover, the touch module in this application embodiment is suitable for OGS structure touch module. By adding light-transmitting holes in the anti-reflection layer, the transmittance of the camera can be improved. The film structure of the touch module is simple and can meet the HDR testing requirements of OLED display.

[0057] It should be noted that the display module of the touch display device in this application is not limited to an OLED display screen, but can also be other types of display screens, such as LCD display screens or micro LED (such as Mini-LED or Micro-LED) display screens. In addition, the touch module is not limited to an OGS structure, but can also be other touch module structures with an anti-shadow layer. The type of touch module in the embodiments of this application is not limited.

[0058] To make the above-mentioned objectives, features and advantages of this application more apparent and understandable, the application will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0059] refer to Figures 1-3 , Figure 1 This is a cross-sectional view of a touch display device provided in an embodiment of this application. Figure 2 for Figure 1 A cross-sectional view of the touch module in the touch display device shown. Figure 3 for Figure 1 Top view of the anti-reflection layer in the touch display device shown.

[0060] like Figure 1 As shown, the touch display device includes a display module 100 and a touch module 101, with the touch module 101 located on the display side of the display module 100. The display side of the display module 100 is also the light-emitting side of the display module 100, and the display module 100 can display images based on the display side.

[0061] Combination Figure 1 and Figure 2 As shown, the touch module 101 includes: a transparent substrate 102; a touch component 103 located on one side surface of the transparent substrate 102; and an anti-reflection layer 104 located on the side of the touch component 103 facing away from the transparent substrate 102. The anti-reflection layer 104 is provided with a light-transmitting port 105, which is disposed opposite to the light-collecting port 107 of the camera 106 on the light-emitting side of the display module 100.

[0062] The display module 100 and the touch module 101 are stacked in a first direction Y, which is parallel to the thickness direction of the display module 100 and the touch module 101. Figure 1 and Figure 2 These are cross-sectional views of the touch display device and the touch module 101 in the thickness direction, respectively, meaning that the cross-section of the cross-section is parallel to the first direction Y. Figure 3 This is a top view of the anti-shading layer 104 with the solid line parallel to the first direction Y, that is, the plane of the top view is perpendicular to the first direction Y.

[0063] Optionally, in the first direction Y, the light-transmitting aperture 105 in the anti-reflection layer 104 and the light-collecting aperture 107 of the camera 106 on the light-emitting side of the display module 100 can be edge-aligned or approximately aligned. In other ways, the apertures of the light-transmitting aperture 105 and the light-collecting aperture 107 can be different, and their centers are directly opposite each other in the first direction Y.

[0064] In the touch display device, a light-transmitting port 105 is provided in the area of ​​the anti-reflection layer 104 of the touch module 101 corresponding to the light-collecting port 107, which can reduce the impact of the anti-reflection layer on the amount of light collected by the camera 106 and improve the image quality.

[0065] refer to Figure 4 , Figure 4 This is a cross-sectional view of a touch module provided in an embodiment of this application. The cross-section of the cross-section is parallel to the first direction Y. Figure 4 The light-transmitting opening in the anti-reflection layer 104 is not shown. For example... Figure 4As shown, the touch component 103 includes: a transparent conductive layer 108 located on the surface of a transparent substrate 102, the transparent conductive layer 108 including: a first transparent touch electrode 109 and a second transparent touch electrode 110; the second transparent touch electrode 110 including a plurality of sub-electrodes; a first transparent insulating layer 111 located on the side of the transparent conductive layer 108 away from the transparent substrate 102; a connecting layer 112 located on the side of the first transparent insulating layer 111 away from the transparent conductive layer 108, the connecting layer 112 including a bridge electrode connecting the sub-electrodes; wherein, an anti-reflection layer 104 is located on the side of the connecting layer 112 away from the transparent conductive layer 108.

[0066] Optionally, the first transparent insulating layer 111 may be an optical adhesive layer.

[0067] The transparent conductive layer 108 can be an ITO layer or other transparent material electrode layer (such as IZO). The first transparent touch electrode 109 and the second transparent touch electrode 110 are formed by patterning the same transparent conductive layer 108.

[0068] The anti-reflection layer 104, projected vertically onto the transparent substrate 102, covers all areas of the transparent substrate 102 except for the light-transmitting opening 105. As an optical matching layer, the anti-reflection layer 104 can fill the pattern gaps in other film layers in the touch component 103, reducing the reflectivity difference between the pattern gap area and the non-pattern gap area, thereby avoiding interference patterns caused by the reflectivity difference.

[0069] Furthermore, the anti-reflection layer 104 can expose at least part of the light-receiving port 107 through the light-transmitting port 105, thereby reducing or even avoiding the impact of the anti-reflection layer 104 in the touch module 101 on the amount of light received by the camera 106, so as to avoid the anti-reflection layer 104 affecting the imaging quality of the camera.

[0070] like Figure 4 As shown, the touch component 103 further includes a second transparent insulating layer 113, which is located between the anti-reflection layer 104 and the bonding layer. Optionally, the second transparent insulating layer 113 may be an optical adhesive layer.

[0071] The connecting layer 112 is a metal layer used for electrical connection to the sub-electrode in the second transparent touch electrode 110. The metal connecting layer 112 has a high reflectivity. Figure 4 In the illustrated configuration, the connecting layer 112 is positioned between the first transparent insulating layer 111 and the second transparent insulating layer 113. The light transmittance of the transparent insulating material can be used to buffer the reflection path and reduce glare.

[0072] Furthermore, since the adhesion of the metal material connecting layer 112 to the anti-reflection layer 104 is relatively weak, the second transparent insulating layer 113 can enhance the adhesion of the anti-reflection layer 104 to the connecting layer 112, thereby strengthening the interfacial bonding strength.

[0073] In addition, the anti-reflection layer 104 is generally an inorganic thin film, such as a silicon nitride thin film, a silicon oxide thin film, or a stacked structure of silicon nitride thin film and silicon oxide thin film. Therefore, compared with optical adhesive, the anti-reflection layer 104 has a larger dielectric constant and rigidity.

[0074] Because the bridge electrodes in the connecting layer 112 need to withstand local pressure and undergo micro-variation during touch operation, if the anti-reflection layer 104 directly covers the surface of the connecting layer 112, the rigidity of the anti-reflection layer 104 will limit the micro-variation of the bridge electrodes and the fatigue deformation of the bridge electrodes. Figure 4 In the illustrated manner, by providing a second transparent insulating layer 113 of optical adhesive material between the anti-reflection layer 104 and the connecting layer 112, the integrity of the metal pattern structure in the connecting layer 112 can be protected based on the elasticity of the optical adhesive to buffer stress during touch operation.

[0075] Because the anti-reflection layer 104 has a large dielectric constant, if it is formed directly on the surface of the connecting layer 112, it will create a large parasitic capacitance, interfering with the signal transmission of the touch electrodes and thus affecting the accuracy of touch detection. Figure 4 In the illustrated method, by providing a second transparent insulating layer 113 of optical adhesive material between the anti-reflection layer 104 and the connecting layer 112, the anti-reflection layer 104 and the connecting layer 112 can be isolated based on the low dielectric constant of the optical adhesive, thereby reducing parasitic capacitance and ensuring the accuracy of touch detection.

[0076] Optionally, the anti-reflection layer 104 is an inorganic thin film, such as a silicon nitride thin film, a silicon oxide thin film, or a stacked structure of silicon nitride and silicon oxide thin films. The first transparent insulating layer 111 and the second transparent insulating layer 113 can be optical adhesive layers, which have a certain elasticity and a smaller dielectric constant compared to the transparent insulating layer.

[0077] In order to better buffer stress and reduce parasitic capacitance through the anti-reflection layer 104, the thickness of the second transparent insulating layer 113 is set to be greater than the thickness of the anti-reflection layer 104.

[0078] Optionally, the refractive index of the anti-reflection layer 104 and the refractive index of the transparent conductive layer 108 meet the same conditions, that is, the refractive index of the anti-reflection layer 104 and the refractive index of the transparent conductive layer 108 are the same or approximately the same, and the difference between their refractive indices does not exceed 20%, further, the difference between their refractive indices does not exceed 10%, and further, the difference between their refractive indices does not exceed 5%. The smaller the difference between their refractive indices, the better the anti-reflection effect of the anti-reflection layer 104. The refractive index difference between the anti-reflection layer 104 and the transparent conductive layer 108 can be set according to requirements.

[0079] The transparent conductive layer 108 has a patterned structure to form the touch electrode with the desired patterned structure. That is, the transparent conductive layer 108 covers the transparent substrate 102 in the area corresponding to the touch electrode, and exposes the transparent substrate 102 in the area outside the touch electrode. Since the transparent conductive layer 108 and the transparent substrate 102 have different refractive indices, the touch module 101 has different refractive indices in the area of ​​the transparent conductive layer 108 corresponding to the touch electrode and the area outside the touch electrode, which makes the patterned structure of the transparent conductive layer 108 visible.

[0080] The refractive index of the anti-reflection layer 104 is the same as or approximately the same as that of the transparent conductive layer 108. By utilizing the principle that the refractive indices of the two are in contact, the visualization problem of the transparent conductive layer 108 caused by the difference in refractive indices between the transparent conductive layer 108 and the transparent substrate 102 can be reduced, thereby reducing or even eliminating the visualization level of the transparent conductive layer 108.

[0081] Optionally, the refractive index of both the anti-reflection layer 104 and the transparent conductive layer 108 is in the range of 1.5 to 2.1, and further, this refractive index range can be 1.8 to 2.1. Within this refractive index range, the refractive index of the anti-reflection layer 104 is similar to that of the transparent conductive layer 108, which can reduce the visualization problem of the transparent conductive layer 108 caused by the difference in refractive index between the transparent conductive layer 108 and the transparent substrate 102.

[0082] Optionally, the thickness of the anti-reflection layer 104 is greater than the thickness of the transparent conductive layer 108. In this way, the anti-reflection layer 104 can better reduce the visualization problem of the transparent conductive layer 108 caused by the difference in refractive index between the transparent conductive layer 108 and the transparent substrate 102.

[0083] The transparent substrate 102 includes a touch area and a non-touch area. The touch area is opposite to the display area of ​​the display module 100, and the non-touch area is opposite to the border area of ​​the display module 100. The touch component 103 is located on the side surface of the transparent substrate 102 facing the display module 100 and within the touch area. The transparent substrate 102 can include the touch component 103 to prevent damage from external forces.

[0084] Optionally, a light-shielding layer 114 is also provided on the non-touch area of ​​the transparent substrate 102 facing the display module 100. The light-shielding layer 114 can be a black ink layer.

[0085] The touch area includes a first region and a second region. In a direction perpendicular to the plane of the transparent substrate 102 (i.e., the first direction Y), the first region overlaps with at least one of the transparent conductive layer 108 and the connecting layer 112, while the second region does not overlap with either the transparent conductive layer 108 or the connecting layer 112.

[0086] Optionally, in the second region, the anti-reflection layer 104 directly contacts the surface of the transparent substrate 102 facing the display module 100. In this method, in the region without the transparent conductive layer 108 and the connecting layer 112, the transparent insulating layer in the second region is removed, and the anti-reflection layer 104 is directly formed on the surface of the transparent substrate 102. This can reduce the interface between different materials in the second region, reduce interface reflection, and better reduce the pattern visibility problem caused by the absence of the transparent conductive layer 108 in the second region.

[0087] In other embodiments, the second region may include a transparent insulating layer, such as a first transparent insulating layer 111 and / or a second transparent insulating layer 113, with the anti-reflection layer 104 located on the surface of the transparent insulating layer in the second region.

[0088] refer to Figures 5-7 , Figures 5-7 Cross-sectional views of a touch module provided in this application embodiment at different process stages. In the touch display device provided in this application embodiment, the touch module 101 can be fabricated based on photolithography. The fabrication method of the touch module 101 includes:

[0089] Step S11: As Figure 5 As shown, a transparent substrate 102 is provided, and an optical adhesive layer 115 is formed on the transparent substrate 102. After the touch component 103 is formed on the transparent substrate 102, an anti-reflection layer 104 is formed over the entire surface.

[0090] in, Figures 5-8 This is a cross-sectional view of the touch module 101 at the light-receiving port 107 corresponding to the camera 106. In the area corresponding to the light-receiving port 107, to avoid the influence of the transparent conductive layer 108 and the connecting layer 112 in the touch component 103 on the amount of light received by the camera 106, the transparent substrate 102 does not have the transparent conductive layer 108 and the connecting layer 112 above the area corresponding to the light-receiving port 107. That is, in the first direction Y, the transparent conductive layer 108 and the connecting layer 112 do not overlap with the light-receiving port 107. Therefore… Figures 5-8 The touch module shown has no transparent conductive layer 108 and connection layer 112 in the area corresponding to the light-collecting port 107.

[0091] The transparent substrate 102 is covered with an optical adhesive layer 115 in the area corresponding to the light-receiving port 107. The optical adhesive layer 115 can be the first transparent insulating layer 111 and / or the second transparent insulating layer 113 mentioned above. Retaining the optical adhesive layer 115 in this area can prevent the transparent substrate 102 from being etched by the subsequent etching of the anti-reflection layer 104.

[0092] Step S12: As Figure 6As shown, a mask layer 116 is formed on the surface of the anti-reflection layer 104. Based on the mask layer 116, hydrofluoric acid is used to etch the anti-reflection layer 104 to remove the anti-reflection layer 104 above the corresponding light-transmitting port 107, so as to form a light-transmitting port 105 on the anti-reflection layer 104.

[0093] Step S13: As Figure 7 As shown, the mask layer 116 is removed to form the touch module 101 with the desired structure.

[0094] exist Figure 5 and Figure 7 In the illustrated method, the touch module 101 is fabricated using a photolithography process. In this fabrication method, the optical adhesive layer 115 is retained on the transparent substrate 102 corresponding to the light-receiving port 107 area. Since the optical adhesive layer includes SiNOx material, it has high light transmittance and has minimal impact on the light transmittance of the light-receiving port 107. Furthermore, it can protect the underlying transparent substrate 102 from hydrofluoric acid corrosion during the formation of the light-receiving port 105.

[0095] The above-mentioned preparation method can be used to prepare the touch module 101 based on the existing photolithography process without adding additional light support, and the preparation process is simple. During the process of etching the anti-shading layer 104 to form the light-transmitting hole 105, the optical adhesive layer 115 already in the touch component 103 can also be used as a protective layer for the transparent substrate 102. Moreover, since the optical adhesive layer has high transmittance, after the light-transmitting hole 105 is formed, the optical adhesive layer 115 in the light-transmitting hole 105 can be retained without additional processing, and it has high mass production capability.

[0096] Based on the touch display device provided in the above embodiments, another embodiment of this application also provides an electronic device, which can perform the following functions: Figure 8 As shown.

[0097] refer to Figure 8 , Figure 8 This is a top view of an electronic device on the display side, provided as an embodiment of this application. (In conjunction with...) Figures 1-3 and Figure 8 As shown, the electronic device includes: a display module 100; and a touch module 101 located on the display side of the display module 100.

[0098] The touch module 101 includes: a transparent substrate 102; a touch component 103 located on one side surface of the transparent substrate 102; and an anti-reflection layer 104 located on the side of the touch component 103 facing away from the transparent substrate 102. The anti-reflection layer 104 is provided with a light-transmitting port 105, which is disposed opposite to the light-collecting port 107 of the camera 106 on the light-emitting side of the display module 100.

[0099] The electronic device adopts the touch display module provided in any of the above embodiments. The anti-reflection layer 104 in the touch display module is provided with a light-transmitting port 105, which can avoid the influence of the anti-reflection layer 104 on the light-collecting port 107, so as to ensure the imaging quality of the camera 106.

[0100] Optionally, the side of the touch module 101 with the anti-reflection layer 104 is bonded and fixed to the display module 100 by an optical adhesive layer; wherein the thickness of the optical adhesive layer is greater than the thickness of the anti-reflection layer 104. The optical adhesive layer has high light transmittance, which not only enables effective bonding and fixing of the touch module 101 and the display module 100, but also ensures good light transmittance to guarantee image display quality and imaging quality.

[0101] Optionally, when the touch module 101 is as follows Figure 4 As shown, the thickness of the optical adhesive layer used to bond and fix the touch module 101 and the display module 100 is greater than the sum of the thicknesses of the anti-reflection layer 104, the second transparent insulating layer 113, the connecting layer 112, and the first transparent insulating layer 111, so that the touch module 101 can be bonded and fixed to the display side of the display module 100 relatively flat.

[0102] like Figure 8 As shown, the electronic device has a display area 117 and a border area 118 surrounding at least a portion of the display area 117; wherein, the camera 106 is located in the border area 118 or at one edge of the display area 117, so as to minimize the occupancy of the camera 106 on the display area 117. Figure 8 The illustrated method uses the camera 106 located in the border area 118 as an example. In other methods, the camera 106 can be located in the display area 117 and near one edge of the display area 117.
