Detailed Description
In the concrete implementation, the capacitive touch screen (Capacitive Touch Panel, CTP) is widely used due to stable performance and simple operation. As shown in fig. 1, fig. 1 is a schematic top view of a conventional capacitive touch screen; the capacitive touch screen is generally formed by a plurality of touch driving electrodes Tx and a plurality of touch sensing electrodes Rx which are disposed to cross each other, and each of the touch driving electrodes Tx and the touch sensing electrodes Rx includes a plurality of electrode blocks 11. Since the touch driving electrode Tx and the touch sensing electrode Rx are disposed to cross each other, the electrode block 11 of one of the two is connected through the bridging metal 12. When the capacitive touch screen is manufactured, as shown in fig. 2, fig. 2 is a schematic diagram of a cross-sectional structure along AA' of the capacitive touch screen shown in fig. 1; a bridge metal 12, a silicon nitride layer 13, and an Indium Tin Oxide (ITO) electrode block 11 are sequentially formed on a substrate base 10.
When light irradiates the capacitive touch screen from the touch side, the propagation path of light is different at the gap of the electrode block 11 from that of the electrode block 11 due to the difference in the structure of the film layers. As shown in fig. 3, fig. 3 is a schematic view of a propagation path of light in a region corresponding to an electrode block; in the region corresponding to the electrode block 11, more reflection and refraction will occur in the optical path, and less light energy will finally enter the human eye. As shown in fig. 4, fig. 4 is a schematic view of the propagation path of light in the corresponding region at the gap of the electrode block; in the corresponding region of the gap between the electrode blocks 11, less reflection and refraction of the light path will occur, and more light energy will eventually enter the human eye, resulting in different intensities of the reflected light in the two regions, which when identified results in the electrodes being visible.
Based on this, the embodiment of the invention provides a touch panel and a display device, which can avoid the problem of electrode visibility by reducing the energy difference of reflected light of two areas.

Therefore, the present invention is not limited by the specific embodiments disclosed below. The description hereinafter sets forth the preferred embodiment for carrying out the present application, but is not intended to limit the scope of the present application in general, for the purpose of illustrating the general principles of the present application. The scope of the present application is defined by the appended claims.
The touch panel and the display device provided by the embodiment of the invention are specifically described below with reference to the accompanying drawings.
As shown in fig. 6 and 8, the touch panel provided by the embodiment of the invention comprises a substrate base plate 01, touch electrodes (02 and 03) positioned on one side of the substrate base plate 01 and an optical compensation structure 04; wherein:
fig. 5 is a schematic structural diagram of a touch electrode in a touch panel according to an embodiment of the invention; the touch electrode comprises a plurality of first touch electrodes 02 and second touch electrodes 03 which are staggered and arranged in an insulating manner; the first touch electrode 02 includes a plurality of first electrode blocks 021 and first connection electrodes 022 arranged at intervals along a first direction X, and two adjacent first electrode blocks 021 are electrically connected through the first connection electrodes 022; the second touch electrode 03 comprises a plurality of second electrode blocks 031 and a bridge-crossing structure 032 which are arranged at intervals along the second direction Y, wherein two adjacent second electrode blocks 031 are electrically connected through the bridge-crossing structure 032, and the second electrode blocks 031 and the bridge-crossing structure 032 are arranged in different layers;
fig. 6 is a schematic structural diagram of a touch panel according to an embodiment of the present invention, as shown in fig. 6 and 8; fig. 8 is a schematic structural diagram of another touch panel according to an embodiment of the present invention; the electrode blocks shown in fig. 6 and 8 are schematic cross-sectional structures of the touch electrode shown in fig. 5 along the BB' direction; the orthographic projection of the optical compensation structure 04 on the substrate 01 at least covers a first area A1, wherein the first area A1 is an area corresponding to a gap between adjacent electrode blocks (021 and 021, 031 and 031, and 021 and 031);
as shown in fig. 7 and 9, fig. 7 is a schematic view of a propagation path of light on the touch panel shown in fig. 6; FIG. 9 is a schematic view of a propagation path of light rays in the touch panel shown in FIG. 8; the optical compensation structure 04 is configured to make the difference between the energy of the light reflected by the first area A1 and the energy of the light reflected by the area corresponding to the electrode block (021 or 031) less than 10%.
According to the touch panel provided by the embodiment of the invention, the optical compensation structure is arranged, and the orthographic projection of the optical compensation structure on the substrate base plate at least covers the area corresponding to the gap between the adjacent electrode blocks; the difference between the energy of the light reflected by the area corresponding to the gap between the adjacent electrode blocks and the energy of the light reflected by the area corresponding to the electrode blocks is smaller than 10% by utilizing the optical compensation structure. The difference in the intensity of the reflected light in the two areas is reduced so that the difference cannot be recognized by human eyes, thereby avoiding the problem of electrode visibility.
In the touch panel provided by the embodiment of the invention, the smaller the difference between the energy of the light reflected by the first area and the energy of the light reflected by the area corresponding to the electrode block is, the less easily the human eye can recognize. The problem of electrode visibility can be avoided by the human eye being unable to recognize as long as the difference between the energy of the light reflected by the first region and the energy of the light reflected by the region corresponding to the electrode block is ensured.
Optionally, in the touch panel provided by the embodiment of the present invention, the optical compensation structure is configured to make a difference between energy of light reflected by a region corresponding to a gap between adjacent electrode blocks and energy of light reflected by a region corresponding to the electrode blocks less than 5%, so that a human eye cannot recognize the difference between the first region and the region corresponding to the electrode blocks.
In the embodiment, the first touch electrode is a touch driving electrode, the second touch electrode is a touch sensing electrode, or the first touch electrode is a touch sensing electrode, and the second touch electrode is a touch driving electrode, which is not limited herein.
In the touch panel provided by the embodiment of the invention, the first electrode block, the second electrode block and the first connection electrode are located on the same layer, and are made of transparent conductive materials, such as ITO, graphene and the like, which are not limited herein.
Optionally, in the touch panel provided by the embodiment of the present invention, as shown in fig. 6 and 8, the material of the bridge structure 032 is a metal material, and the bridge structure 032 is located between the electrode block 031 and the substrate 01; a second inorganic insulating layer 05 is further disposed between the electrode blocks 031 and the bridge-crossing structure 032, and two adjacent second electrode blocks 031 are electrically connected through vias penetrating through the second inorganic insulating layer 05. That is, during the preparation, the bridge structure 032 is formed first, then the second inorganic insulating layer 05 is formed, and finally the first electrode block 021, the second electrode block 031 and the first connection electrode 022 are formed.
Of course, in the implementation, the bridge structure may also be located at a side of the electrode block away from the substrate, that is, during the preparation, the first electrode block 021, the second electrode block 031 and the first connection electrode 022 are formed first, then the second inorganic insulating layer 05 is formed, and finally the bridge structure 032 is formed, which is not limited herein. But when the bridge structures are located on the side of the electrode block facing away from the substrate base plate, a risk of the bridge structures being visible occurs.
In the conventional touch screen, because the film layer structures of the first area and the area corresponding to the electrode block are different, more reflection and refraction can occur in the area corresponding to the electrode block, and finally, the light energy entering the human eyes is less, so that the light energy entering the human eyes in the first area can be reduced in order to reduce the difference between the first area and the electrode block.
Therefore, optionally, in the touch panel provided by the embodiment of the invention, as shown in fig. 6, the optical compensation structure 04 includes a shielding layer 041 filled in the gap between the adjacent electrode blocks (021 and 021, 031 and 031, and 021 and 031). As shown in fig. 7, in the first region, light is sequentially irradiated onto the shielding layer 041, the second electrodeless insulating layer 05 and the substrate base 01 through air, and the reflected light includes: light reflected from the interface of the shielding layer 041 and air, light reflected from the interface of the shielding layer 041 and the second electrodeless insulating layer 05, and light reflected from the interface of the second electrodeless insulating layer 05 and the substrate 01; in the region corresponding to the electrode block, light passes through air and sequentially irradiates onto the electrode block 021, the second electrodeless insulating layer 05 and the substrate base plate 01, and the reflected light comprises: light reflected from the interface between the electrode block 021 and air, light reflected from the interface between the electrode block 021 and the second electrodeless insulating layer 05, and light reflected from the interface between the second electrodeless insulating layer 05 and the substrate 01. Thus, the shielding layer 041 absorbs the energy of the light incident on the first region, so that the energy of the light entering the human eye from the first region A1 is reduced, and the difference between the energy of the light reflected by the region corresponding to the gap between the adjacent electrode blocks and the energy of the light reflected by the region corresponding to the electrode blocks is not recognized by the human eye.
Optionally, in the touch panel provided by the embodiment of the present invention, the material of the shielding layer may be a material with poor reflection effect, for example, the material of the shielding layer is a light-absorbing material, and the light-absorbing material may absorb energy of light incident on the first area. Thereby reducing the difference in energy of light reflected by the region corresponding to the gap between the adjacent electrode blocks and the region corresponding to the electrode blocks.
Alternatively, in the touch panel provided by the embodiment of the present invention, the material of the shielding layer may be an amorphous silicon material, which is not limited herein. When the shielding layer is made of amorphous silicon material, the amorphous silicon material is brown-black or gray-black microcrystal, so that light can be absorbed, the surface of the amorphous silicon material is rough, the incident light is diffusely reflected on the surface of the amorphous silicon, and the light reflection effect is poor.
Or, alternatively, in the touch panel provided by the embodiment of the present invention, as shown in fig. 10, fig. 10 is a schematic structural diagram of the shielding layer provided by the embodiment of the present invention; the shielding layer 041 has a plurality of protrusions 0410 on a side facing away from the substrate, so that incident light is diffusely reflected on the side of the shielding layer 041 facing away from the substrate. Because the incident light can be diffusely reflected on the surface of the shielding layer 041, the light reflection effect is poor, so that the energy of the light incident on the first area is absorbed, the energy of the light entering the human eye in the first area is reduced, and the energy of the light reflected by the area corresponding to the gap between the adjacent electrode blocks is close to the energy of the light reflected by the area corresponding to the electrode blocks.
In practical implementation, the more protrusions 0410 are positioned on one side of the shielding layer 041 away from the substrate, the better diffuse reflection effect is, but the embodiment of the invention needs to meet the requirement that the energy of the light reflected by the shielding layer 041 is close to the energy of the light reflected by the electrode block.
Optionally, in the touch panel provided by the embodiment of the present invention, as shown in fig. 8, the optical compensation structure 04 includes a first inorganic insulating layer 042 covering the touch electrodes (02 and 03), and a virtual electrode 043 located on a side of the first inorganic insulating layer 042 facing away from the substrate 01 and covering each first area A1;
the virtual electrode 043 is the same material and thickness as the electrode block (021 or 031); the virtual electrode 043 covers the first area A1 in front projection of the substrate base 01. As shown in fig. 9, in the first region, light is sequentially irradiated onto the dummy electrode 043, the first inorganic insulating layer 042, the second electrodeless insulating layer 05, and the substrate base plate 01 through air, and the reflected light includes: light reflected from the interface between the virtual electrode 043 and air, light reflected from the interface between the virtual electrode 043 and the first inorganic insulating layer 042, light reflected from the interface between the first inorganic insulating layer 042 and the second electrodeless insulating layer 05, and light reflected from the interface between the second electrodeless insulating layer 05 and the substrate base plate 01; in the region corresponding to the electrode block, light passes through air and irradiates onto the first inorganic insulating layer 042, the electrode block 021, the second electrodeless insulating layer 05 and the substrate base plate 01 in sequence, and the reflected light comprises: light reflected from the interface between the first inorganic insulating layer 042 and air, light reflected from the interface between the first inorganic insulating layer 042 and the electrode block 021, light reflected from the interface between the electrode block 021 and the second electrodeless insulating layer 05, and light reflected from the interface between the second electrodeless insulating layer 05 and the substrate base plate 01. Therefore, the virtual electrode 043 and the electrode block (021 or 031) are made of the same material and have the same thickness, so that the optical characteristics of the virtual electrode 043 and the electrode block (021 or 031) are the same, and the energy of the light reflected by the area corresponding to the gap between the adjacent electrode blocks is close to the energy of the light reflected by the area corresponding to the electrode block, so that the whole reflection effect of the touch panel is uniform.
In a specific implementation, in the touch panel provided by the embodiment of the present invention, as shown in fig. 11, fig. 11 is a schematic top view of the relative positions of the virtual electrode and the electrode block in one embodiment of the present invention; the front projection of the boundary of the virtual electrode 043 on the substrate 01 and the front projection of the boundary of the electrode block (021 or 031) on the substrate 01 may just overlap, or, as shown in fig. 12, fig. 12 is a schematic top view of the relative positions of the virtual electrode and the electrode block in another embodiment of the present invention; of course, the boundary of the dummy electrode 043 may be projected onto the substrate 01 so as to surround the boundary of the electrode block (021 or 031) on the front side of the substrate 01, even if the dummy electrode 043 overlaps the electrode block (021 or 031) to some extent.
Optionally, in the touch panel provided by the embodiment of the present invention, the material of the first inorganic insulating layer is silicon nitride or silicon oxide, which is not limited herein.
Specifically, in the touch panel provided by the embodiment of the invention, the thickness of the first inorganic insulating layer cannot be too thick, which affects the overall light transmittance of the touch panel, and the thickness of the first inorganic insulating layer cannot be too thin, which is easy to cause short circuit between the virtual electrode and the electrode block. Therefore, optionally, in the touch panel provided by the embodiment of the invention, the thickness of the first inorganic insulating layer is about 50nm to 200nm. Therefore, the whole light transmittance of the touch panel can be ensured, and the short circuit between the virtual electrode and the electrode block can be avoided.
Based on the same inventive concept, the embodiment of the invention also provides a display device, as shown in fig. 13, and fig. 13 is a schematic structural diagram of the display device provided by the embodiment of the invention; the display device comprises a display panel 100 and a touch panel 200 positioned on the light emitting side of the display panel 100. Since the principle of the display device for solving the problem is similar to that of the aforementioned touch panel, the implementation of the display device can be referred to the implementation of the aforementioned touch panel, and the repetition is omitted.
In specific implementation, in the display device provided in the embodiment of the present invention, the display panel may be any type of panel such as a liquid crystal display panel or an OLED display panel, which is not limited herein.
