In order to improve touch sensitivity, an embodiment of the present invention provides a touch screen, including a substrate, a plurality of first touch electrodes extending along a row direction and a plurality of second touch electrodes extending along a column direction on the substrate, and a dielectric layer between the first touch electrodes and the second touch electrodes; the thickness of the dielectric layer in the overlapped area of the first touch electrode and the second touch electrode is larger than that of other areas.
In the embodiment of the invention, in the dielectric layer between the two touch electrodes, the thickness of the overlapped area of the two touch electrodes is larger than that of other areas, for example, the thickness of the overlapped area of the two touch electrodes is larger than that of the overlapped area of the two touch electrodes at the edge, and correspondingly, the generated capacitance is smaller than that at the edge, so that the influence on the touch effect is reduced, and the touch sensitivity is improved.
The specific structure of the dielectric layer is various, and the following lists several structures that can realize that the thickness of the dielectric layer in the overlapping area of the first touch electrode and the second touch electrode is greater than that of other areas: preferably, one of the upper surface and the lower surface of the dielectric layer is flat, and the other surface of the dielectric layer is provided with a plurality of outer convex structures; or the upper surface and the lower surface of the dielectric layer are both provided with a plurality of convex structures, and the convex structures on the upper surface and the lower surface are in one-to-one correspondence. Correspondingly, the overlapped area of the first touch electrode and the second touch electrode is located in the area where the outer protruding structure of the dielectric layer is located.
The solution provided by the present invention is explained in more detail below with reference to the drawings and examples.
Referring to FIGS. 1 a-1 c: the touch screen includes a substrate 001, a plurality of first touch electrodes 002 extending in a row direction and a plurality of second touch electrodes 003 extending in a column direction on the substrate 001, and a dielectric layer 004 between the first touch electrodes and the second touch electrodes.
In fig. 1a, the upper surface of the dielectric layer 004 is flat, the lower surface has an outer protrusion structure 041, and the overlapping region 005 of the first touch electrode and the second touch electrode is located in the region where the outer protrusion structure 041 of the dielectric layer is located; the outer protrusion structure on the lower surface is used to make the thickness of the dielectric layer in the overlapping area 005 of the first touch electrode and the second touch electrode larger than that in other areas.
In fig. 1b, the lower surface of the dielectric layer 004 is flat, the upper surface has an outer protrusion structure 041, and the overlapping region 005 of the first touch electrode and the second touch electrode is located in the region where the outer protrusion structure 041 of the dielectric layer is located; the outer protrusion structure on the upper surface is used to make the thickness of the dielectric layer in the overlapping area 005 of the first touch electrode and the second touch electrode larger than that in other areas.
In fig. 1c, the upper and lower surfaces of the dielectric layer 004 have a plurality of outer protrusion structures 041, and the outer protrusion structures 041 of the upper and lower surfaces are in one-to-one correspondence; the overlapping region 005 of the first touch electrode and the second touch electrode is located in the region where the outer protrusion structure 041 of the dielectric layer is located; the outer convex structures on the upper and lower surfaces are used together to make the thickness of the dielectric layer in the overlapping area 005 of the first touch electrode and the second touch electrode larger than that in other areas.
The above illustrates only a few possible configurations of the dielectric layer and other configurations are possible and are not listed here.
In one possible embodiment, the outer protrusion structure of the upper surface and/or the lower surface of the dielectric layer is located at the non-pixel region. Therefore, the first touch electrode and the second touch electrode can be transparent electrodes or non-transparent electrodes, and can be selected according to the actual process. For example, in the top view shown in fig. 2, the first touch electrode 002 is above the second touch electrode 003, the solid line frame shows the pixel region 006, the dotted line frame shows the region where the dielectric layer 004 is located, the upper surface of the dielectric layer 004 has an outer protrusion structure, which is located in the non-pixel region and can be reflected by the bending position of the first touch electrode 002, and in fig. 2, the overlapping region of the first touch electrode 002 and the second touch electrode 003 is in the non-pixel region.
In another possible embodiment, the outer convex structure of the upper surface and/or the lower surface of the dielectric layer is positioned in the pixel area; correspondingly, the first touch electrode and the second touch electrode are transparent electrodes. Thus, the aperture ratio of the pixel region can be secured. For example, as shown in the top view of fig. 3, the first touch electrode 002 is below the second touch electrode 003, and the lower surface of the dielectric layer has an outer protrusion structure located in the pixel region 006, which can be reflected by the bending position of the first touch electrode 002, and in fig. 3, the overlapping area of the first touch electrode 002 and the second touch electrode 003 is in the pixel region. Since the thickness of the overlapping region of the first touch electrode 002 and the second touch electrode 003 is greater than the thickness of the other regions, it can be known from the knowledge about capacitance that the capacitance C1 in the overlapping region is smaller than the capacitance C2 at the edge, thereby facilitating to improve the sensitivity.
It should be noted that the scheme of the embodiment of the present invention is applicable to a mutual-capacitive touch screen. Preferably, the touch screen may be, but not limited to, an Organic Light-emitting Diode (OLED) or a Liquid Crystal Display (LCD) display panel. In a specific implementation, the first touch electrode, the second touch electrode and the dielectric layer are preferably located inside the display panel.
If the touch screen is an OLED display panel, preferably, the touch screen further includes a pixel defining layer for defining a plurality of grooves arranged in a matrix as pixel regions, and an organic electroluminescent layer on the pixel defining layer; when the lower surface of the dielectric layer is provided with the outer convex structure, the outer convex structure of the lower surface of the dielectric layer is positioned in the pixel area, and the outer convex structure of the lower surface of the dielectric layer is in one-to-one correspondence with the grooves of the pixel defining layer. In the embodiment, the groove is formed in the pixel defining layer, so that the outer convex structure of the dielectric layer can be formed by utilizing the groove of the pixel defining layer when the outer convex structure of the lower surface of the dielectric layer is manufactured in the manufacturing process, and thus, the outer convex structure of the dielectric layer is formed by utilizing the appearance of the existing structure, an additional process is not needed, the process is simpler, and the production efficiency is favorably improved.
In specific implementation, the first touch electrode, the second touch electrode and the dielectric layer are arranged at various positions, and preferably, the touch screen further comprises a packaging layer; the first touch electrode, the second touch electrode and the dielectric layer are positioned inside the packaging layer or on the packaging layer. When the packaging layer is inside, the packaging layer not only has a packaging function, but also has a touch function.
In specific implementation, the packaging layer comprises a first water-resistant layer, a flat layer and a second water-resistant layer which are stacked; when the first touch electrode, the second touch electrode and the dielectric layer are positioned in the packaging layer, the dielectric layer is a flat layer. In the embodiment, the existing flat layer in the packaging layer is used as the dielectric layer, so that the structure is simplified, and the thickness of the product can be reduced.
In the embodiment of the present invention, the substrate may be, but is not limited to, a flexible substrate.
It should be noted that the first touch electrode and the second touch electrode in the embodiment of the present invention may be used for not only realizing touch but also realizing fingerprint identification. Because fingerprint identification has a high requirement on precision, in specific implementation, the touch screen may include a touch area and a fingerprint identification area, and the density of the first touch electrode and the second touch electrode arranged in the fingerprint identification area is higher than the density of the first touch electrode and the second touch electrode arranged in the touch area. Or, in specific implementation, the touch area and the fingerprint identification area are not distinguished, but when fingerprint identification is realized, all the first touch electrodes and all the second touch electrodes are used for fingerprint identification; when the touch control is realized, a part of the first touch control electrode and the second touch control electrode are used for touch control. In practice, one of them may be selected as required.

The outer protrusion structure on the upper surface of the dielectric layer 004 may make the thickness of the dielectric layer in the overlapping area of the first touch electrode and the second touch electrode larger than that of other areas.
