All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to be within the scope of the utility model.

In the related art, a touch screen generally includes four frames, which are an upper frame, a lower frame, a left frame and a right frame, respectively, wherein the upper frame, the left frame and the right frame can have smaller widths, but because the lower frame is a position where a binding area is located, the touch screen is affected by factors such as the number of wires and binding terminals of the binding area, and the distance between the wires in the related art is 30 μm, so that the width of the lower frame is generally larger.

In view of the above, an embodiment of the present utility model provides a touch screen, a touch device, and a display device, where the touch screen includes a touch area and a non-touch area, the touch area includes a plurality of first touch electrodes and a plurality of second touch electrodes, the non-touch area includes a plurality of frame areas, the plurality of frame areas are located at different sides of the touch area, the plurality of frame areas includes at least two binding frame areas, the binding frame areas are provided with at least one binding area, and the binding area is connected with the first touch electrodes and/or the second touch electrodes; through setting up a plurality of frame areas and setting up at least one binding area in at least two binding frame areas, can make the wiring evenly distributed of first touch electrode and second touch electrode to a plurality of frame areas to make the interval of walking the line can reduce, and then make the width in frame area reduce thereupon, and then realize the narrow frame of touch-sensitive screen.

Referring to fig. 1, a touch screen according to an embodiment of the present utility model includes a touch area a and a non-touch area B surrounding the touch area a.

Specifically, the touch area a is an area of the touch screen for realizing a touch function, so that the touch area a corresponds to a position of a display area in the display panel, and when the display panel emits light, the light passes through the touch area a to realize display of an image.

Referring to fig. 1, the touch area a includes a first touch electrode 10 extending in a first direction and a second touch electrode 20 extending in a second direction, the first and second directions intersecting each other and being perpendicular to each other. And, the first touch electrode 10 and the second touch electrode 20 are insulated from each other. The first touch electrode 10 includes a plurality of first sub-electrodes 101, and the second touch electrode 20 includes a plurality of second sub-electrodes. The plurality of first sub-electrodes 101 and the plurality of sub-electrodes 102 fully occupy a touch area of the touch screen.

When a finger or a stylus of a user touches the screen, the first touch electrode 10 and the second touch electrode 20 in the touch area a generate touch signals due to capacitance changes, so that the touch coordinates of the touch screen can be calculated through the touch signals.

Further, referring to fig. 1, the non-touch area B has a plurality of frame areas 30, the plurality of frame areas 30 are located at different sides of the touch area a, the plurality of frame areas 30 include at least two binding frame areas, the binding frame areas are provided with at least one binding area 40, and the binding area 40 is connected with the first touch electrode 10 and/or the second touch electrode 20.

Specifically, the non-touch area B is an area of the touch screen where no touch effect is generated, and generally no display effect is generated in the non-touch area B.

The non-touch area B may include a plurality of border areas 30, and the plurality of border areas 30 are located at different sides of the touch area. For example, when the touch screen is rectangular in overall shape and the outer contour shape of the touch area a is also rectangular, the non-touch area B may include four border areas 30, and the four border areas 30 are located at the upper, lower, left, and right sides of the touch area a, respectively.

In the embodiment of the present utility model, the plurality of frame areas includes at least two binding frame areas, and at least one binding area 40 is disposed in each binding frame area, where the binding area 40 is connected to the first touch electrode 10 and/or the second touch electrode 20.

Specifically, the binding frame area is the frame area where the binding area 40 is located, and at the same time, the plurality of frame areas further includes an unbound frame area, that is, a frame area where the binding area 40 is not provided. In the embodiment of the utility model, at least two or more binding frame areas are arranged. As an example, referring to fig. 3 and 4, when the touch screen is rectangular as a whole and the outer contour shape of the touch area a is also rectangular, the non-touch area B may include four border areas 30, and a first binding border area 301 and a second binding border area 302 may be included in the four border areas 30, wherein the first binding border area 301 is located at the left side of the touch area a, the second binding border area 302 is located at the right side of the touch area a, and at least one binding area is disposed in each of the first binding border area 301 and the second binding border area 302.

In addition, the first touch electrode 10 and the bonding area 40, and the second touch electrode 20 and the bonding area 40 are connected by wires, and the wires between the bonding area 40 and the first touch electrode 10 and the second touch electrode 20 are disposed in each frame area 30 of the non-touch area B.

In the embodiment of the present utility model, the binding area 40 is provided with a plurality of binding frame areas and is distributed in different binding frame areas, so that when the binding area 40 is connected with the first touch electrode 10 and the second touch electrode 20 by using wires, the wires for connection can be uniformly distributed in each frame area 30. The wirings are not concentrated in one area, and thus the width of each of the frame regions 30 can be reduced, compared to the related art.

Meanwhile, in the embodiment of the present utility model, the pitch between the wirings is 16 μm or more and 18 μm or less, and illustratively, the pitch between the wirings may be 16 μm, 17 μm, 18 μm, or the like. In the embodiment of the utility model, the spacing between the wires is 16 μm. By adopting the limit wiring line design, the width of the frame area 30 can be reduced more effectively, so that a touch screen with four narrow frames is realized.

Further, the dimension of the binding frame area in the direction of pointing the touch screen edge to the touch area A is greater than or equal to 3mm and less than or equal to 5mm. Illustratively, the dimensions of the bezel area 30 in the direction in which the touch screen edge points to the touch area a may be 3mm, 4mm, 5mm, etc., and those skilled in the art may design the same according to the actual situation. Illustratively, the dimension of the unbound border zone in the direction of the touch screen edge pointing to touch zone a is greater than or equal to 3mm and less than or equal to 5mm, and the dimension of the unbound border zone in the direction of the touch zone a is less than or equal to the dimension of the bound border zone in the direction of the touch zone a. In actual products, the size of the unbound border zone will generally be smaller than the size of the bound border zone. In the embodiment of the utility model, the frame area 30 at the lower side of the touch area a is an unbound frame area, so that compared with the display device in the related art, the problem of wider lower frame of the conventional display can be solved.

Further, referring to fig. 2, the non-touch area B further includes a grounding area B1, a first routing area B2, and a second routing area B3.

Specifically, referring to fig. 3, the ground region B1 is disposed along the circumferential direction of the touch region a, that is, the ground region B1 is disposed at least one turn along the touch region a; meanwhile, the grounding area B1 is provided with a grounding electrode, and the grounding electrode is a grounding wire of the binding area.

The first routing area B2 and the second routing area B3 are also provided with a circle along the touch area a, the first routing area B2 is used for setting a routing for connecting the second touch electrode 20 and the binding area 40, and the second routing area B3 is used for setting a routing for connecting the first touch electrode 10 and the binding area 40. In a partial region within the binding frame region, a first routing region B2 is disposed between the binding region 40 and the touch region a, and a second routing region B3 is disposed between the binding region 40 and the ground region B1. It should be noted that, the grounding area B1, the first routing area B2, and the second routing area B3 are not a complete circle in an actual product, when a plurality of binding areas are provided in the binding frame area, a grounding electrode and a routing are generally not provided between two adjacent binding areas, and therefore, the grounding area B1, the first routing area B2, and the second routing area B3 are disconnected at positions of the two adjacent binding areas.

It can be understood that the grounding area B1 is an area where the grounding electrode is located, and the first routing area B2 and the second routing area B3 are routing areas, where the routing may be distributed in the first routing area B2 and the second routing area B3 at the same time.

Specifically, the design of the grounding region B1 affects the ESD (Electrostatic Discharge ) performance of the touch screen. In the embodiment of the present utility model, three schemes are adopted for the grounding region B1 in total.

In the first scheme, the ground area B1 is provided with only one turn, the size of the ground area B1 in the direction in which the touch screen edge points to the touch area a is 150 μm, the line distance between the ground area B1 and the first or second routing area B2 or B3 is 100 μm, and the distance between the ground area B1 and the touch screen edge is 609 μm.

In a second solution, the grounding area B1 is provided with two turns, a first grounding area and a second grounding area, wherein the second grounding area is arranged at the side of the first grounding area away from the display area. The first grounding area and the second grounding area are 150 μm in the direction of pointing to the touch area A from the edge of the touch screen, the line distance between the first grounding area and the second grounding area and the first wiring area B2 or the second wiring area B3 is 100 μm, and the distance between the second grounding area and the edge of the touch screen is 360 μm.

In the third scheme, the grounding area B1 is provided only one turn, but the size of the grounding area B1 in the direction in which the edge of the touch screen points to the touch area a increases to 200 μm, and the line distance between the grounding area B1 and the first or second routing area B2 or B3 is 75 μm.

The above solutions can optimize the ESD performance of the touch screen without changing the width of the bezel area 30. Further, the size of the ground region B1 in the direction in which the touch screen edge points to the touch region a may be 150 μm or more and 200 μm or less. Illustratively, the size of the ground region B1 in the direction in which the touch screen edge points to the touch region a may be 150 μm, 160 μm, 170 μm, 180 μm, 190 μm, 200 μm, etc., and a person skilled in the art may actually need to make a selection.

Further, the first touch electrode 10 and the second touch electrode 20 are arranged in different layers or in the same layer.

In the case that the first touch electrode 10 and the second touch electrode 20 are arranged in different layers, the first sub-electrode 101 or the second sub-electrode 201 does not need to be connected through a bridge.

In the case that the first touch electrode 10 and the second touch electrode 20 are arranged in the same layer, the first touch electrode 10 includes a first sub-electrode 101 connected through a bridge, and the second touch electrode 20 includes a second sub-electrode 201 connected to each other; alternatively, the first touch electrode 10 includes the first sub-electrodes 101 connected to each other, and the second touch electrode 20 includes the second sub-electrodes 201 connected through a bridge.

Specifically, the first sub-electrodes 101 may be connected or interconnected by a bridge, and the second sub-electrodes 201 may be connected or interconnected by a bridge, but the connection modes of the first sub-electrodes 101 and the second sub-electrodes 201 are different, so that insulation between the first touch electrode 10 and the second touch electrode 20 can be ensured.

In addition, the first sub-electrode 101 may be a touch electrode or a sensing electrode, and the second sub-electrode 201 may be a touch electrode or a sensing electrode, but the types of the first sub-electrode 101 and the second sub-electrode 102 are different. Illustratively, when the first sub-electrode 101 is a touch electrode, the second sub-electrode 201 is a sensing electrode; when the first sub-electrode 101 is an induction electrode, the second sub-electrode 201 is a touch electrode.

According to the touch screen provided by the embodiment of the utility model, the plurality of binding areas 40 positioned in the at least two binding frame areas are arranged, so that the wires for connecting the first touch electrode 10 and the second touch electrode 20 with the binding areas 40 can be uniformly distributed in each frame area 30, the wires for connecting the binding areas 40 with the first touch electrode 10 and the second touch electrode 20 can not be concentrated in one area, each frame area 30 can be made into a narrow frame, and additional cost is not increased. In addition, the extremely narrow frame can also promote the cutting number, improves the glass utilization ratio, and can bring brand-new visual experience to the user.
