Detailed Description
The following detailed description of embodiments of the invention refers to the accompanying drawings. It should be understood that the detailed description and specific examples, while indicating the present invention, are given by way of illustration and explanation only, not limitation.
Fig. 1 is a schematic diagram of a stacked structure of a touch module according to an embodiment of the present invention, as shown in fig. 1, the touch module includes a touch substrate 1, the touch substrate 1 includes a substrate 11 and a plurality of touch electrodes 12 disposed on the substrate 11, the touch electrodes 12 are disposed on the same layer and spaced apart from each other, and the touch electrodes 12 are made of a transparent conductive material. The touch module further comprises a shadow eliminating layer 2, the shadow eliminating layer 2 is made of transparent materials, and the orthographic projection of the shadow eliminating layer 2 on the substrate 11 is located in an interval area between the adjacent touch electrodes 12.
Fig. 2 is a top view of a touch substrate according to a first embodiment of the invention, and fig. 3 is a top view of a shadow layer according to the first embodiment of the invention, and with reference to fig. 1 and fig. 2, the touch electrodes 12 may include a plurality of first electrodes 121 and a plurality of second electrodes 122, and the first electrodes 121 and the second electrodes 122 are disposed in an intersecting manner. The first electrode 121 is a continuous strip electrode made of a transparent conductive material, and includes a plurality of first electrode units 121a and a connection portion 121b connected between each adjacent two of the first electrode units 121 a. The second electrode 122 is composed of a plurality of second electrode units 122a, and every adjacent two second electrode units 122a are spaced apart by the first electrode 121. A plurality of bridges 13 are provided on the substrate 11, and adjacent two second electrode units 122a are connected by the bridges 13. The first electrode 121 and the second electrode unit 122a are located at the same layer, and the bridge 13 and the connection portion 121b are located at different layers and are insulated from each other. One of the first electrode 121 and the second electrode 122 is a touch sensing electrode, and the other is a touch driving electrode. As shown in fig. 2 and fig. 3, an orthographic projection of the vanishing layer 2 on the substrate 11 is located in an interval between the second electrode unit 122a and the adjacent first electrode unit 121a, and the orthographic projection of the vanishing layer 2 on the substrate 11 and an orthographic projection of the touch electrode 12 on the substrate 11 do not overlap.
The term "disposed on the same layer" means that each touch electrode 12 is formed by the same material layer through a patterning process, and therefore each touch electrode 12 is in the same layer in a lamination relationship; this does not mean that the distances between the respective touch electrodes 12 and the substrate 11 are necessarily the same. In the present invention, "transparent material" and "transparent conductive material" mean a material having a transmittance of 90% to 100%.
Since the transmittance of the touch electrode 12 cannot reach 100% transparency, and the larger the thickness of the touch electrode 12 is, the larger the difference between the transmittance and the reflectance of the spacing region between the region where the touch electrode 12 is located and the region where the touch electrode 12 is located is, and the larger the area of the region where the touch electrode 12 is located relative to the spacing region is, the image of the spacing region is easily seen outside the touch module without the shadow eliminating layer 2. In the invention, the position corresponding to the spacing region between the touch electrodes 12 is provided with the shadow eliminating layer 2, the shadow eliminating layer 2 is also made of transparent material, and the transmittance of the shadow eliminating layer 2 does not reach 100%, so that the difference between the transmittance and the reflectance of the region where the touch electrodes 12 are located and the spacing region between the regions where the touch electrodes 12 are located is reduced, and further, under the condition that the thickness 12 of the touch electrodes is not reduced, the afterimages seen by naked eyes are reduced or eliminated, namely, the shadow eliminating effect is improved under the condition that the process difficulty is not increased.
Preferably, the materials and thicknesses of the vanishing layer 2 and the touch electrode 12 are the same, so as to ensure that the transmittance and the reflectivity of the vanishing layer 2 and the touch electrode 12 are the same, and reduce the difference between the vanishing layer 2 and the touch electrode 12 seen by naked eyes at the outer side of the touch module. Optionally, the vanishing layer 2 and the touch electrode 12 may be made of Indium Tin Oxide (ITO), and the thickness of the vanishing layer 2 and the touch electrode 12 is 0.3-0.5 μm.
Further preferably, the orthographic projection of the vanishing layer 2 on the substrate 11 completely covers the interval area between the adjacent touch electrodes 12, that is, the orthographic projection of the vanishing layer 2 on the substrate 11 completely coincides with the interval area between the adjacent touch electrodes 12, so that the orthographic projection of the vanishing layer 2 on the substrate 11 and the orthographic projection of each touch electrode 12 on the substrate 11 form a continuous area, and the transmittance and the reflectance of each position in the whole touch area of the whole touch module are equal or close, thereby preventing the occurrence of afterimage.
The touch module is particularly suitable for a touch display module to have touch and display functions. Specifically, as shown in fig. 1, the touch module further includes a display panel 3 and a back film 4, the touch substrate 1 is disposed on the light emitting side of the display panel 3, and the back film 4 is disposed on the side of the display panel 3 departing from the touch substrate 1. Optionally, the display panel 3 is a flexible organic electroluminescent (OLED) display panel, and may specifically include a flexible display substrate and display devices such as a light emitting unit and a thin film transistor disposed on the display substrate, and the back film 4 is disposed on a side of the flexible display substrate away from the display devices to protect the flexible display substrate. Of course, the display panel 3 may be a liquid crystal display panel.
The touch module further comprises a main driving circuit board and a touch driving circuit board (not shown), wherein the main driving circuit board is electrically connected with the binding area of the display panel 3 through a first flexible circuit board, and the touch driving circuit is electrically connected with the binding area of the touch substrate 1 through a second flexible circuit board. The touch drive circuit board and the main drive circuit board are both positioned on one side of the back film 4 departing from the display panel 3. The touch driving electrode is electrically connected with the binding region of the touch substrate 1, and the touch driving circuit board is used for providing a touch driving signal to the touch driving electrode 12 through the binding region of the touch substrate 1 and judging a touch position by detecting a sensing signal on the touch sensing electrode. The main driving circuit board is used for providing display driving signals for the display devices of the display panel 3 through the binding region of the display panel 3 so as to control the display of the display panel 3; and controlling the touch driving circuit board to detect the touch position.
As shown in fig. 1, the touch module further includes a polarizer 5 and a cover plate 6, where the polarizer 5 is disposed opposite to the touch substrate 1 and located on a side of the touch substrate 1 away from the display panel 3. The polarizer 5 is a circular polarizer for reducing reflection of external light. The cover plate 6 is arranged opposite to the touch substrate 1 and is positioned on one side of the polarizer 5 departing from the touch substrate 1; the polarizer 5 and the cover plate 6 are fixedly connected through a bonding layer.
In the first embodiment, as shown in fig. 1, the shadow eliminating layer 2 is disposed on the back film 4 and located on a side of the back film 4 away from the display panel 3. At this moment, the layer of vanishing 2 can play the guard action to notacoria 4, prevents that notacoria 4 from being by the fish tail, consequently, works as when the touch-control module is used for fingerprint identification device and sets up the clearing hole on notacoria 4, can not influence fingerprint identification effect because of notacoria 4 fish tail. In addition, the touch driving circuit board and the main driving circuit board can be electrically connected through the shadow eliminating layer 2, so that other independent connecting structures are not needed, the structure is simplified, and the production cost is saved.
Fig. 4 is a schematic diagram of a stacked structure of a touch module according to a second embodiment of the present invention, which similarly to the first embodiment, includes a vanishing layer 2, and an orthographic projection of the vanishing layer 2 on the substrate 11 is located in a spacing region between adjacent touch electrodes 12.

Because the polarizer 5 is thin, the shadow eliminating layer 2 is arranged on one side of the polarizer 5, which is far away from the touch substrate 1, so that the polarizer 5 can be smoothly attached to the touch substrate 1.
Fig. 5 is a schematic diagram of a stacked structure of a touch module according to a third embodiment of the present invention, which similarly to the first embodiment, includes a vanishing layer 2, and an orthographic projection of the vanishing layer 2 on the substrate 11 is located in a spacing region between adjacent touch electrodes 12. The difference between the third embodiment and the first embodiment is only that the position of the vanishing layer 2 is different, as shown in fig. 5, the vanishing layer 2 of the third embodiment is disposed on the cover plate 6 and located on a side of the cover plate 6 facing the touch substrate 1.
In the second and third embodiments, the difference between the transmittance and the reflectance of the area where the touch electrode 12 is located and the gap area between the areas where the touch electrode 12 is located can be reduced by the arrangement of the vanishing layer 2, so as to improve the vanishing effect.
Of course, the arrangement of the vanishing layer in the present invention is not limited to the manner of the first to third embodiments, as long as the orthographic projection of the vanishing layer 2 on the substrate 11 is located in the spacing region between the adjacent touch electrodes 12.
