Description
Technical Field
The invention belongs to the technical field of display equipment, and particularly relates to a touch screen and display equipment.
Background
Currently, with the rapid development of display technologies, touch screens have been widely used in various fields. Generally, as shown in fig. 1, a basic structure of a touch screen includes a substrate and a conductive layer disposed on the substrate, where the conductive layer includes a first conductive layer and a second conductive layer which are layered and electrically insulated by an insulating layer, such as an OC (over coat) glue layer.
The touch screen is divided into a visible area and a non-visible area, the conductive layer is composed of touch electrodes and electrode leads, namely the first conductive layer is composed of first touch electrodes and first electrode leads, and the second conductive layer is composed of second touch electrodes and second electrode leads. The touch electrode is arranged in the visible area, the electrode lead is arranged in the invisible area, and the binding part is arranged on the invisible area. The electrode leads may be electrically connected with the driving device at the binding portion through leads of an FPC (flexible circuit board) or other electrical connection structure to form a binding.
A touch electrode of a traditional ITO touch screen is made of an ITO material, and an electrode lead is made of a metal material. Generally, the first touch electrode and the second touch electrode are manufactured by one process, and after an insulating layer is disposed, the first electrode lead and the second electrode lead are manufactured by another process. Because the touch electrode and the electrode lead are arranged in different areas, the well-made touch electrode patterns can not be influenced when the electrode lead is manufactured.
With the development of touch screen technology, touch screens in which both touch electrodes and electrode leads are made of the same metal material have been developed, for example, OGM (one Glass metal) touch screens, that is, metal grid integrated touch screens, generally, a first touch electrode and a first electrode lead of an OGM touch screen are manufactured in the same process, a second touch electrode and a second electrode lead are manufactured in the same process, the first touch electrode and the second touch electrode are different two-layer structures, and an insulating layer is sandwiched between the two-layer structures for electrical insulation, the touch electrodes and the electrode leads on the same layer are designed in the same process, and the electrical connection reliability and stability are high.
However, the current conventional OGM touch screen plating process is: when the first touch electrode and the first electrode lead are manufactured, a whole metal film layer is plated, and then the first touch electrode and the first electrode lead are manufactured on the whole metal film layer in an exposure and development mode. Because the first touch electrode and the second touch electrode are on different layer structures, an insulating layer needs to be arranged after the first touch electrode and the first electrode lead are manufactured, so that the first touch electrode and the first electrode lead which are manufactured completely are prevented from being damaged by the exposure and development processes when the second touch electrode and the second electrode lead are manufactured, and particularly, the pattern of the first touch electrode is prevented from being damaged.
However, if the insulating layer covers the entire surface of all the first electrode leads, the first electrode leads are completely insulated, and the first touch electrode and the driving device cannot be electrically connected and bound through the first electrode leads and the leads of the FPC. In order to solve the above problems, some manufacturers have to connect the first electrode lead to the driving device by one or more processes.
Disclosure of Invention
The present invention is directed to overcome the above-mentioned deficiencies of the prior art, and provides a touch panel and a display device, which at least protect a first touch electrode pattern from being damaged when a second touch electrode and a second electrode lead are manufactured, and simultaneously, through the existing process, the first touch electrode and a driving device can be electrically connected to each other well through the first electrode lead and the FPC lead without adding additional processes.
The embodiment of the invention provides a touch screen.
The touch screen comprises a substrate and a conducting layer, wherein the conducting layer is arranged on the substrate and comprises a first conducting layer and a second conducting layer which are vertically stacked, and an insulating layer is clamped between the first conducting layer and the second conducting layer; the touch screen is divided into a non-visual area and a visual area.
The first conducting layer comprises a first touch electrode arranged in the visible area and a first electrode lead arranged in the invisible area, the first electrode lead comprises a first electrode lead and a first lap joint part which are electrically connected, and the first lap joint part extends towards the binding position direction of the connecting driving device. The first touch electrode and the first electrode lead can be manufactured in one process.
The second conducting layer comprises a second touch electrode arranged in the visible area, a second electrode lead and a first redundant electrode lead, wherein the second electrode lead and the first redundant electrode lead are arranged in the invisible area, the second touch electrode, the second electrode lead and the first redundant electrode lead can be manufactured in one process, the second electrode lead comprises a second electrode lead and a second binding portion which are electrically connected with each other, and the second binding portion and the second electrode lead electrically conduct the second touch electrode with the driving equipment.
The second binding portion and the first redundant electrode lead both extend in a direction of a binding position to which the driving device is connected.
The first redundant electrode lead is electrically isolated from the second touch electrode and the second electrode lead.
The insulating layer sandwiched between the first conductive layer and the second conductive layer at least covers all the first touch electrodes, so that insulation is formed between the first touch electrodes and the second touch electrodes. The first lap joint part is at least partially not covered by the insulating layer, the first redundant electrode lead and the first lap joint part are at least partially projected and overlapped on the substrate, and the electrical connection with the first redundant electrode lead is realized through the partial structure of the first lap joint part which is not covered by the insulating layer.
A first grid-shaped touch electrode is arranged on the first conducting layer, and the outer edge line of the grid is a first electrode lead; a second grid-shaped touch electrode is arranged on the second conducting layer, and the outer edge line of the grid is a second electrode lead; therefore, the first conducting layer and the second conducting layer are insulated and separated through the insulating layer, and mutual capacitance is generated between the second touch electrode and the first touch electrode, so that a capacitive touch screen is formed.
In an actual manufacturing process, the first conductive layer is manufactured first, and in order to keep consistency of the first touch electrode and the second touch electrode connected to the driving device through the electrode lead without deviation, the first electrode lead is not directly connected to the driving device at this time, and a distance is reserved, that is, the first lapping part is not directly bonded to the driving device.
Then, an insulating layer is manufactured, the insulating layer at least covers the whole visible area to insulate the first touch electrode and the second touch electrode, and meanwhile, the insulating layer at least does not cover the part of the first lap joint part to reserve lap joint with the first redundant electrode lead.
And then, manufacturing a second conductive layer, wherein the second touch electrode is connected to the driving equipment through a second electrode lead. The first lap joint part is lapped on the first redundant electrode lead through a partial structure which is not covered by the insulating layer, and the first electrode lead is electrically connected to the driving device.
Because the temperature is higher during film plating, after the first electrode lead on the first conducting layer is plated, the first redundant electrode lead on the second conducting layer is plated, the first electrode lead is cooled, the temperature difference is larger when the two layers of electrode leads are laminated, and if the laminating area is large, the serious problem of poor adhesion and combination can exist based on the principle of expansion with heat and contraction with cold, and even metal falling can occur. In order to improve the adhesion reliability, some manufacturers adopt a mode of additionally arranging an adhesive layer on the two-layer laminated electrode lead wire of the manufactured non-visible area, so as to improve the adhesion stability. However, this method increases the production process and the labor cost, and also has a poor effect and a large amount of poor adhesion.
In order to solve the problem of poor adhesion, the first overlapping part comprises a plurality of overlapping support legs arranged at intervals, and the overlapping support legs extend towards the binding position. Through the design of the lap joint support legs arranged at intervals, the lamination area of the first redundant electrode lead and the first lap joint part can be reduced, the lamination adhesion between two layers of metal is improved, and meanwhile, enough lap joint sites with the first redundant electrode lead can be guaranteed.
However, when the landing leg of the first landing part is landed with the first redundant electrode lead, cracks are easily generated at three-sided edges of the landing leg.
In order to reduce the resistance between the first electrode lead and the driving device, through a plurality of experimental researches, it is found that one or a plurality of conducting parts are arranged on the first overlapping part, and the first redundant electrode lead can be indirectly conducted with the overlapping support leg of the first overlapping part through the climbing of the conducting parts. At this time, the number of cracks between the landing leg and the first redundant electrode lead may be greatly reduced, and even no cracks will occur. Therefore, a plurality of conduction channels are increased between the first lapping part and the first redundant electrode lead wire through the conduction part, so that the resistance can be effectively reduced.
The invention further provides display equipment which comprises the touch screen, a display module and a bonding layer for bonding the touch screen and the display module into a whole.
Based on the structural design, in the technical scheme of the invention, the first redundant electrode lead is manufactured on the second conductive layer and can be indirectly conducted with the first lap joint part through the climbing of the conducting part, so that a plurality of conducting channels can be increased between the first lap joint part and the first redundant electrode lead through the conducting part, thereby effectively reducing the resistance and further reducing the reliability risk of the touch screen.

The specific meanings of the above terms in the present invention can be understood by those skilled in the art according to specific situations.
The embodiment of the invention provides a touch screen.
Referring to fig. 2 to 4, the touch screen includes a substrate (not shown) and a conductive layer (not labeled), wherein the conductive layer is disposed on the substrate and includes a first conductive layer 1 and a second conductive layer 2 stacked up and down, and an insulating layer 3 is interposed between the first conductive layer 1 and the second conductive layer 2; the touch screen is divided into a non-visible area 10 and a visible area 201.
Referring to fig. 2, the first conductive layer 1 includes a first touch electrode 21 disposed in the visible region 20 and a first electrode lead 100 disposed in the non-visible region 10, the first electrode lead 100 includes a first trace portion 110 and a first strap portion 120 electrically connected to each other, and the first strap portion 120 extends toward a bonding position connected to a driving device (not shown).
In an alternative, the width of the first strap portion 120 is greater than the line width of the first wire trace portion 110.
Referring to fig. 3, the second conductive layer 2 includes a second touch electrode 22, a second electrode lead 200 and a first redundant electrode lead 220, the second electrode lead 200 includes a second routing portion 210 and a second binding portion 230 electrically connected to each other, and the second binding portion 230 and the first redundant electrode lead 220 both extend toward a binding position direction connected to the driving device so as to be electrically connected to the driving device.
The second binding portion 210 and the second wire portion 210 electrically conduct the second touch electrode 22 with the driving device. The first redundant electrode lead 220 is electrically isolated from the second touch electrode 22 and the second electrode lead 200.
Optionally, the line widths of the first redundant electrode lead 220 and the second binding portion 230 are greater than the line width of the second routing portion 210.
Alternatively, the end point of the first redundant electrode lead 220 in the extending direction to the bonding location is closer to the bonding location than the first lap joint part 120.
Referring to fig. 4, the insulating layer 3 is sandwiched between the first conductive layer 1 and the second conductive layer 2, and the insulating layer 3 at least covers all of the first touch electrodes 21, so that the first touch electrodes 21 and the second touch electrodes 22 are insulated from each other. The first bonding part 120 is at least partially not covered by the insulating layer 3, the first redundant electrode lead 220 and the area of the first bonding part 120 not covered by the insulating layer 3 at least partially overlap in projection on the substrate, and the electrical connection with the first redundant electrode lead 220 is realized by the partial structure of the first bonding part 120 not covered by the insulating layer 3.
Referring to fig. 5, the first overlapping portion 120 includes a plurality of overlapping legs 221 spaced apart from each other, and the overlapping legs 221 extend toward the binding position. Through the design of the overlapping legs 221 arranged at intervals, the lamination area of the first redundant electrode lead 220 and the first overlapping part 120 can be reduced, the lamination adhesion between two layers of metal is improved, and meanwhile, enough overlapping sites with the first redundant electrode lead 220 can be guaranteed.
Referring to fig. 6, when the landing leg 221 of the first landing part 120 is landed with the first redundant electrode lead 220, cracks 222 are easily generated at three-sided edges where the landing leg 221 is not covered by the insulating layer 3. The crack 222 may cause resistance between the first electrode lead 100 and the driving device to become large.
Referring to fig. 7 to 8, due to the appearance requirement and the production practical result in some cases, the overlapping leg 221 of the first overlapping part 120 is often made into an inverted trapezoid structure, so that when the first redundant electrode lead 220 is overlapped with the overlapping leg 221 of the first overlapping part 120 to form an inverted step structure, a crack is more easily formed between the first overlapping part 120 and the first redundant electrode lead 220, and thus the resistance between the first electrode lead 100 and the driving device is particularly high, and the electrical performance of the touch screen is greatly reduced.
Referring to fig. 5, in order to reduce the resistance, in the present embodiment, one or more conductive portions 300 are disposed on the first bonding portion 120, and the first redundant electrode lead 220 can be indirectly conducted with the bonding leg 221 of the first bonding portion 120 through the climbing of the conductive portion 300.

In selected embodiments, the conduction part 300 has a structure that allows the first redundant electrode lead 220 to smoothly climb.
In a preferred embodiment, the conductive portion 300 and the insulating layer 3 are made of the same insulating material and completed in one process.
It should be noted that, in this embodiment, the touch screen is specifically an ogm (on Glass metal) touch screen, and in the type of touch screen, the structural design may also be applied to other situations where the resistance at the climbing position is abnormal due to the metal reverse step of the bonding portion. Generally, a touch screen includes sensors and driving devices, such as a chip of the touch screen, in addition to a substrate.
Of course, in other embodiments, the conduction portions 300 of the OC adhesive tape insulating material may be disposed only on the partial overlapping legs 221, and the number and the positions of the conduction portions are not limited herein. For example, in another embodiment as shown in fig. 9, a plurality of vias 300 are disposed on each of the overlapping legs 221, and the plurality of vias 300 are arranged at intervals along the length direction of the overlapping legs 221, and the electrical overlapping of the overlapping legs 221 and the first redundant electrode lead 220 is formed at the interval regions formed by the plurality of vias 300 arranged at intervals, so that the current conducting path between the electrode leads can be further increased.
In this embodiment, the conductive part 300 may be a rectangular design, and the length thereof is preferably in the range of 30-100um, so that a better current conduction effect can be obtained when the first overlapping part 120 and the first redundant electrode lead 220 are overlapped. Of course, in other embodiments, the specific shape and size of the conducting portion 300 can be designed according to practical situations, and are not limited herein.
However, the design is not limited thereto, and in other embodiments, the first redundant electrode lead 220 and the second binding portion 230 both extend outward to the binding position.
