All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.
The terms "first," "second," "third," and "fourth," if any, in the description and claims of this application and the above-described figures are used for distinguishing between similar elements and not necessarily for describing a particular sequential or chronological order. It is to be understood that the data so used is interchangeable under appropriate circumstances such that the embodiments of the application described herein are capable of operation in sequences other than those illustrated or described herein. Furthermore, the terms "comprises," "comprising," and "having," and any variations thereof, are intended to cover a non-exclusive inclusion, such that a process, method, system, article, or apparatus that comprises a list of steps or elements is not necessarily limited to those steps or elements expressly listed, but may include other steps or elements not expressly listed or inherent to such process, method, article, or apparatus.
At present, touch sensor more commonly used includes resistance-type and capacitanc, and wherein, capacitanc touch sensor has advantages such as high sensitivity, long-life and high light transmittance, and its theory of operation is: at least one layer of transparent conductive substance is arranged on the surface of the substrate to form a touch structure, when a conductive object (such as a human finger) touches the surface of the capacitive touch sensor, the capacitance at a touch point is changed, and the position of the touch point, namely a coordinate value, can be calculated according to the variation of the capacitance.
The touch sensor pattern mentioned in the embodiments of the present application below may also be referred to as a touch sensor structure.
The touch sensor pattern provided by the present application can be applied to a folding screen, and fig. 1 is a schematic structural diagram of the folding screen according to an embodiment of the present application; as shown in fig. 1, the folding screen includes: a cover plate 101, a transparent optical adhesive 102, a polarizer 103, a protective layer 104, a sensing unit, and an organic light-emitting diode (OLED) display unit. The sensing unit includes a bridge member layer 105, an insulating layer 106, and a touch sensor pattern layer 107. The touch sensor pattern is disposed on the touch sensor pattern layer 107, i.e., under the cover 101. The OLED display unit includes a thin film encapsulation layer 108, an OLED cathode 109, a display pixel 110, a Thin Film Transistor (TFT) driving circuit 111, and a substrate 112. A touch pattern layer 107 for implementing touch detection; the protective layer 104 is used for protecting the sensing unit and preventing the sensing unit from being scratched, oxidized and the like; and the thin film packaging layer 108 is used for preventing moisture or oxygen from damaging the OLED material.
In order to realize touch detection, the driving electrodes and the sensing electrodes on the touch sensor pattern layer 107 need to be formed into a special pattern.

Capacitive coupling quantity exists between the driving electrode 202 and the sensing electrode 201 to form mutual capacitance, and the distance between the driving electrode 202 and the sensing electrode 201 can be adjusted by the suspension block 203, so that the size of the mutual capacitance is adjusted. The suspension block 203 may be a metallic material. As shown in fig. 2C, the grid-patterned part 204 of the touch sensor includes a bridging component 205 and an insulating layer 206, since the driving electrode 202 and the sensing electrode 201 are made on the same plane and need to vertically cross each other, the driving electrode 202 can be connected by the bridging component 205, and the insulating layer 206 can be used to isolate the bridging component 205 from the sensing electrode 201, so as to prevent the two from being short-circuited.

This form of touch sensor pattern meshing is commonly referred to as MetalMesh. But the amount of capacitive coupling of the touch sensor pattern is small and the suspension performance is still poor, the present application provides another embodiment to better address the suspension performance.
The touch sensor pattern provided by the embodiments of the present application is described below with reference to various embodiments. It should be noted that, for convenience of description, the sizes of different structures in the touch sensor pattern structure are enlarged or reduced, so that the sizes and the ratios shown in the drawings of the present application do not necessarily represent actual sizes, nor reflect the proportional relationship of the sizes.

The upper left corner, the upper right corner, the lower left corner and the lower right corner of the sensing unit 40 are distributed on the suspension block 403 to avoid the connection of sensing electrodes of the sensing unit 40 between different rows. The sensing unit 40 includes 8 floating blocks 403, and a ratio of a total area of the 8 floating blocks 403 to a sum of areas of the sensing electrode 401 and the driving electrode 402 is less than 1. Preferably, the ratio of the area of the floating mass 403 to the sum of the areas of the sensing electrode 401 and the driving electrode 402 is greater than 0.5 and less than 1.5. The ratio of the area of the floating mass 403 to the sum of the areas of the sensing electrode 401 and the driving electrode 402 may be any one of 0.5, 0.8, 1, 1.2, and 1.5, and preferably, the ratio of the areas is 1.
The shape and number of the floating blocks 403 may be arbitrary, the floating blocks 403 are made of conductive material, such as metal or alloy, and are generally in a free state, and the floating blocks 403 occupy the areas of the sensing electrodes 401 and the driving electrodes 402 to reduce the electrode areas, thereby reducing the capacitive coupling amount between the sensing electrodes 401 and the driving electrodes 402. Likewise, the amount of capacitive coupling between sense electrode 401 and drive electrode 402 can be increased by increasing the electrode area by decreasing the area of sense electrode 401 and drive electrode 402 occupied by suspended mass 403. The capacitance coupling amount can be determined according to the requirements of actual products.
The sensing unit 40 includes two first driving electrodes 4021 arranged along the same direction, and the two driving electrodes 402 are connected by a bridging component 405. Any two adjacent sensing cells 40 in the X-axis direction are connected to each other through the first sensing electrode 4011, and any two adjacent sensing cells 40 in the Y-axis direction are connected to each other through the first driving electrode 4021.
Further, the suspension block 403 may be divided into small blocks. For example, the floating blocks 403 distributed at the upper left corner, the upper right corner, the lower left corner and the lower right corner of the sensing unit 40 are divided into 3 small blocks, and the floating blocks 403 at the gap between the first driving electrode 4021 and the second driving electrode 4022 are divided into 2 small blocks. The floating mass 403 is divided into small pieces to reduce the influence of the short circuit of the driving electrode 401 or the sensing electrode 402 with the floating mass 403.
Compared with the existing patterns, the touch sensor pattern provided by the application improves the capacitance variation and reduces the capacitance coupling amount between the hand and the driving electrode 401 and/or the sensing electrode 402. Under the same touch sensor pattern area, the capacitive coupling between the driving electrode 401 and the sensing electrode 402 can be increased, and the capacitance variation is increased, so that the floating effect is improved. The advantage of low resistance of metal materials forming the touch pattern is fully utilized, the coupling capacitance is increased, and meanwhile the whole channel resistance-capacitance attenuation is also considered.
The touch sensor pattern can be applied to products such as smart phones, tablets, bracelets and electronic newspapers. On the premise of meeting the process capability, the driving electrode 401 and the sensing electrode 402 can be coupled as much as possible to improve the touch variation and reduce the areas of the driving electrode 401 and the sensing electrode 402 which are ineffective in improving the capacitance variation.

To further enhance the coupling capacitance between the driving electrode 501 and the sensing electrode 502, two metal wires are generally used to form one driving electrode 501 or one sensing electrode 502 according to the process capability.
