Currently, electronic devices support more and more communication bands and WiFi bands. In order to prevent the performance of the WiFi antenna from being affected by the switching of the frequency bands of the communication system, the WiFi antenna and the communication antenna which are independent of each other need to be arranged in the electronic device.

Such different types of communication antennas also often need to be separately disposed within the electronic device.

However, the WIFI antenna and the multiple communication antennas are respectively and independently arranged, and an independent space large enough to accommodate the WIFI antenna and the multiple communication antennas is required to be reserved in the electronic device, which is not favorable for realizing the lightness and thinness of the electronic device.

With the development of mobile communication technology, electronic devices support more and more communication frequency bands and WiFi frequency bands. In order to prevent the performance of the WiFi antenna from being affected by the switching of the frequency bands of the communication system, the WiFi antenna and the communication antenna which are independent of each other need to be arranged in the electronic device. Further, the communication antenna includes, for example, in accordance with a communication frequency band: a 5G millimeter wave radio-frequency antenna for 5G Communication, a UWB radio-frequency antenna for Ultra Wide Band (UWB) Communication, and an NFC antenna for Near Field Communication (NFC), and the like. Such different types of communication antennas also often need to be separately disposed within the electronic device. However, the WIFI antenna and the multiple communication antennas are respectively and independently arranged, and an independent space large enough to accommodate the WIFI antenna and the multiple communication antennas is required to be reserved in the electronic device, which is not favorable for realizing the lightness and thinness of the electronic device.

In order to solve the above problems, in the related art, the electronic device may be adapted to antennas in different communication frequency bands and WiFi frequency bands, such as the main mobile communication antenna 01, the WiFi and bluetooth antenna 02, and the GPS and NFC antenna 03 shown in fig. 1, and may use LDS antennas, and be fabricated on a housing or a frame of the electronic device 1000, so as to achieve the lightness and thinness of the electronic device.

Here, the LDS (Laser-Direct-structuring) antenna is an antenna prepared by directly forming an antenna pattern using Laser. Specifically, in the antenna forming process, firstly, a computer is utilized to control laser movement according to the track of a conductive pattern so as to project laser onto a three-dimensional plastic support formed by molding; and then activating the circuit pattern within a few seconds, namely directly plating the bracket to form metal by using a laser technology.

The embodiment of the application provides a touch cover plate, a touch screen and electronic equipment, which are used for reducing the space occupation of an antenna in the electronic equipment so as to realize the lightness and thinness of the electronic equipment; meanwhile, the service life and the reliability of the antenna are improved.

The electronic device provided by the embodiment of the application includes a product having a touch function and a display function, such as a mobile phone, a tablet computer, a Personal Digital Assistant (PDA for short), or a vehicle-mounted computer. The embodiment of the present application does not specifically limit the specific form of the electronic device. For convenience of description, the following description will be given taking an electronic device as a mobile phone as an example.

As shown in fig. 2 and 3, the electronic device 1000 includes a touch screen 1, a middle frame 2, and a rear case 3. The middle frame 2 is located between the touch screen 1 and the rear shell 3. The touch screen 1 and the rear shell 3 are respectively connected with the middle frame 2. Wherein, the accommodating cavity formed between the rear shell 3 and the middle frame 2 can accommodate a battery, a camera (not shown in fig. 3), and electronic components such as a PCB as shown in fig. 3. It is to be understood that the present application is exemplified by this embodiment, but is not limited thereto.

Illustratively, the PCB is mounted on the middle frame 2 or the rear case 3. An Application Processor (AP) is usually disposed on the PCB. The touch panel 1 may be coupled to a PCB through a Flexible Printed Circuit (FPC).

It can be understood that, referring to fig. 4, the touch screen 1 has a touch display function, and the touch screen 1 includes: a display panel 11 and a touch cover 10. The display panel 11 includes: a passive light emitting display panel or an active light emitting display panel. The passive light emitting Display panel is, for example, a Liquid Crystal Display (LCD) panel. The active light emitting display panel is, for example: an Organic Light-emitting Diode (OLED) display panel, a micro LED (micro LED) display panel, or a Mini LED (Mini LED) display panel.

In some examples, as shown in fig. 4, the touch cover 10 may be attached to the display side of the display panel 11, for example, by being adhered by an optical adhesive (OCA) 12.

In addition, the touch screen 1 further includes a touch IC. The touch IC is connected to the touch signal lines in the touch cover 10, and is capable of sending a driving signal to the corresponding touch signal lines (e.g., driving lines Tx) and performing touch recognition according to the touch signal transmitted by the corresponding touch signal lines (e.g., sensing lines Rx). The touch IC may be disposed on the PCB or integrated into the touch screen 1. And the touch IC is coupled with the AP and can perform information interaction with the AP.

Referring to fig. 5, an embodiment of the present invention provides a touch cover 10, which includes a substrate 101, a plurality of touch electrodes 110, and a plurality of antennas 201. The touch cover 10 has a touch area a1 and a peripheral area a2 at least partially surrounding the touch area a 1. Touch electrodes 110 are disposed in the touch area a 1. The base material 101 is used for carrying the touch electrode 110, and may be a rigid substrate or a flexible substrate.

In some examples, the rigid substrate may be a glass substrate.

In some examples, the flexible substrate may be a polyethylene terephthalate (PET) resin sheet or a Polyimide (PI) resin sheet.

Note that the touch area a1 corresponds to the display area of the display panel 11, and both generally have the same shape and area. That is, in the touch panel 1, the display area coincides with the orthographic projection of the touch area a1 on the substrate 101. The peripheral area a2 is located at the periphery of the touch area a1 and is used for accommodating touch signal lines (Rx and Tx) and other peripheral wirings.

It is understood that the structure of the touch electrode 110 may be different according to the touch principle of the touch screen 1. The embodiment of the present application takes the example that the touch screen 1 adopts the capacitive touch principle as an example for explanation.

The capacitive touch includes: self-capacitance touch and mutual capacitance touch.

In the touch cover 10 using self-contained touch, the touch electrodes 110 are formed by patterning a single conductive layer. Each touch electrode 110 is led out through one sensing line and connected to a touch IC.

In the touch cover 10 using mutual capacitive touch, the touch electrodes 110 include: a plurality of drive electrodes and a plurality of sense electrodes; so as to form a capacitor by using the matched driving electrode and the induction electrode. Each driving electrode is led out through one driving line and connected to the touch IC. Each induction electrode is led out through one induction line and connected to the touch IC.

In addition, according to different forming modes of the driving electrode and the sensing electrode, the mutual capacitance type touch control comprises single-layer mutual capacitance type touch control and double-layer mutual capacitance type touch control.

In the touch cover 10 using single-layer mutual capacitance touch, for example, as shown in fig. 5, the driving electrode 111 and the sensing electrode 112 are patterned from the same transparent conductive layer. For example: a first transparent conductive part arranged in a column direction and a second transparent conductive part arranged in a row direction are formed from the same transparent conductive layer. The first transparent conductive part of each row extends along the row direction and is integrated to form a driving electrode 111. The second transparent conductive parts of each row are separated by the first transparent conductive parts, and the separated adjacent second transparent conductive parts are connected by metal bridge lines to form the sensing electrodes 112. An insulating layer is arranged between the metal bridging line and the transparent conductive layer.

In the touch cover 10 using the double-layer mutual capacitance touch, the driving electrode 111 and the sensing electrode 112 are respectively formed by two transparent conductive layers of different layers. For example: the driving electrodes arranged in the column direction are formed from the first transparent conductive layer. And forming sensing electrodes arranged along the row direction from the second transparent conductive layer. An insulating layer is arranged between the first transparent conducting layer and the second transparent conducting layer.

Accordingly, the touch cover 10 generally includes at least one conductive layer, such as one transparent conductive layer, two transparent conductive layers, or one transparent conductive layer and one metal conductive layer.

In an example, referring to fig. 6, the touch screen 1 adopts a single-layer mutual capacitive touch, and the touch cover 10 includes: a metal conductive layer 102, an insulating layer 103, a transparent conductive layer 104, and a protective layer 105 are sequentially stacked in a direction away from the base material 101.

The metal conductive layer 102 is used to form a metal bridge line. The metal conductive layer 102 may be formed of a metal having good electrical properties, such as copper, silver, gold, nickel, or titanium, or an alloy thereof.

The transparent conductive layer 104 is used to form a driving electrode 111 and a sensing electrode 112. The transparent conductive layer 104 may be formed using a transparent conductive material having high visible light transmittance and high conductivity, such as Indium Tin Oxide (ITO), zinc oxide (ZnO), Cadmium Tin Oxide (CTO), indium oxide (InO), indium (In) -doped zinc oxide (ZnO), aluminum (Al) -doped zinc oxide (ZnO), or gallium (Ga) -doped zinc oxide (ZnO).

The insulating layer 103 is formed using a light-transmitting insulating material having a high dielectric constant, and can effectively insulate the metal conductive layer 102 from the transparent conductive layer 104.

The protective layer 105 is used to improve the compressive strength of the touch cover 10 to protect the touch cover 10. The protective layer 105 is, for example, a glass layer subjected to chemical strengthening treatment.

Optionally, the touch cover 10 further includes a vanishing layer 106 located between the substrate 101 and the metal conductive layer 102. The shadow eliminating layer 6 is formed by at least one of silicon oxynitride material, silicon oxide material, silicon nitride material or niobium oxide material. The shadow eliminating layer 6 can reduce or eliminate the residual shadow seen by the eyes of the user so as to improve the display effect of the touch screen.

Referring to fig. 5, the antennas 201 are respectively disposed in the peripheral areas a 2. The plurality of antennas 201 may be disposed on one side of the substrate 101 where the touch electrode 110 is disposed, on one side of the substrate 101 away from the touch electrode 110, or on both sides of the substrate 101. The embodiment of the present application does not limit the specific arrangement position of the antenna 201.

The plurality of antennas 201 may include: at least two antennas with different communication types. For example, the plurality of antennas 201 includes at least: mobile communication main antennas, WiFi and bluetooth antennas, and GPS and NFC antennas, etc. In addition, the structure, shape, size and number of the antennas 201 can be selected according to actual requirements.

It is to be added that the structures of the various different communication type antennas 201 may be identical or similar, e.g. each comprising an element and a feed line. The oscillator and the feeder can be made of conductors, especially metal with excellent conductivity. Based on this, the antenna 201 is optionally a line antenna or a surface antenna, and is obtained by patterning a conductive layer, especially a metal conductive layer, by using a patterning process.

It is understood that the plurality of antennas 201 may be specially prepared in the peripheral region a2, or may be reused with some process identifiers already on the substrate 101. Of course, the process identification that can be multiplexed into the antenna 201 includes at least one conductive layer.

In some embodiments, the process identifier is disposed on the same layer as the touch electrode 110. That is, the process mark and the touch electrode 110 may be formed simultaneously using the same conductive material and the same patterning process. Based on this, the antenna 201 may be formed by multiplexing process identifiers, so that an additional antenna manufacturing process is not required, which is beneficial to improving the production efficiency of the electronic device.

In addition, the plurality of touch electrodes 110 are formed by patterning a single-layer or double-layer transparent conductive layer, for example, and the process identifier may be formed by patterning the single-layer or double-layer transparent conductive layer. But not limited thereto, the process indicator may be formed by patterning the metal conductive layer.

In some embodiments, as shown in fig. 6, the touch cover 10 includes: a metal conductive layer 102, an insulating layer 103, a transparent conductive layer 104, and a protective layer 105 are sequentially stacked in a direction away from the base material 101. The metal conductive layer 102 and/or the transparent conductive layer 104 are/is formed with a process identifier which is reused as the antenna 201.

Optionally, the metal conductive layer 102 is formed with a process identifier multiplexed as the antenna 201. Thus, the antenna 201 is formed by multiplexing the process identifier formed by the metal material, which can ensure the impedance requirement of the antenna 201 to ensure that the antenna 201 has stable communication capability. The material of the metal conductive layer 102 is not limited to a simple metal such as copper, silver, gold, nickel, or titanium, or an alloy thereof.

Optionally, the metal conductive layer 102 and the transparent conductive layer 104 are both formed with process identifiers which are reused as the antenna 201; wherein, the process identifiers located in the same area and different layers are interconnected and multiplexed into the same antenna 201. Therefore, the impedance requirement of the antenna 201 can be further guaranteed in a space with a small plane area.

With continued reference to fig. 5, the peripheral region a2 includes: an antenna setting area A21 and a touch wiring area A22. The antenna setting area a21 is located at the periphery of the touch wiring area a 22. The antenna 201 is located within the antenna disposition area a 21. The antenna mounting area a21 is an edge area of at least one side of the peripheral area a2, for example, the antenna mounting area a21 is an area of the touch cover 10 for connecting to the middle frame 2. Thus, the presence of the antenna 201 in the antenna installation area a21 does not cause a defect in the screen occupation ratio of the touch screen 1.

The touch cover 10 further includes: touch signal line and antenna lead La. The touch signal lines are correspondingly connected to the touch electrodes 110 and disposed in the touch routing area a 22. The antenna lead La is connected to the antenna 201 and disposed in the antenna installation area a 21. Optionally, the touch signal line includes a driving line Tx and a sensing line Rx.

Furthermore, in some examples, the process identification multiplexed as the antenna 201 has a space from the touch routing area a 22. In this way, the process identifier and the antenna lead La multiplexed as the antenna 201 in the antenna setting area a21 can both keep a certain distance from the touch signal line, so as to reduce the signal interference of the touch signal line to the antenna 201. Here, the size of the gap may be set according to practical requirements, for example, the gap is greater than or equal to 0.5 mm and less than 1 mm.

Optionally, the package boundary of the touch signal line is located in the foregoing space. Therefore, the preparation and packaging of each film layer structure and the touch signal line thereof in the touch area can be ensured, and the antenna 201 and the antenna lead La cannot be influenced.

Optionally, in a case where the antenna 201 and the touch electrode 110 are located on the same side of the substrate 101, the antenna lead La and the touch signal line may be formed by using the same patterning process, so as to simplify a manufacturing process of the touch cover 10.

With continued reference to fig. 5, in some embodiments, the peripheral area a2 further includes: a bonding area a23 located at one side of the touch area a 1. The leading-out end of the antenna lead La and the bonding end of the touch signal line are located in the bonding area a 23. Thus, the antenna lead La and the touch signal line can be led out to the binding region a23 to be bound by the same FPC, so that the binding of the antenna 201 and the touch signal line with the corresponding IC or PCB is achieved by using the FPC. In addition, in the example where the antenna 201 and the touch electrode 110 are respectively located on two sides of the substrate 101, the antenna lead La and the touch signal line may be bonded on the front and back sides of the same FPC.

In the embodiment of the present application, the antenna 201 is led out through the antenna lead La, and is bound in the binding region a23 through the FPC, which can have a better binding effect, so as to reduce the risk of failure of the antenna 03 due to disconnection. Thereby contributing to the improvement of the service life and reliability of the antenna 201. Moreover, the antenna lead La and the touch signal line share the same FPC for binding, which not only simplifies the production process of the electronic device 1000 to improve the production efficiency of the electronic device 1000, but also further reduces the space occupation of the antenna 201 related connection structure in the electronic device 1000.

It should be added that the antenna 201 is formed by multiplexing some process marks already on the substrate 101. The process mark is generally formed within the peripheral area a 2. The process identifier may have various structures and applications according to the process requirements of the touch cover 10. For example, process identification that can be multiplexed as antenna 201 includes: at least one of a film formation positioning mark, a binding positioning mark or a patch alignment mark.

Here, the film formation positioning mark is a positioning mark for aligning a mask or a manufacturing tool when a certain thin film is formed. The binding positioning identifier is a positioning identifier used for aligning the FPC or binding a tool when a touch signal line or other signal lines are bound. The paster alignment mark is an alignment mark used for aligning the position of a film or an attaching tool when attaching optical films such as an optical adhesive layer or a polaroid.

It is understood that the process identifier multiplexed as the antenna 201 is not limited to the above process identifier, and other identifiers prepared or reserved according to the process requirement and including the conductive layer may also be considered to be multiplexed as the antenna 201. The formation of the process marks depends on the process requirements of the touch cover 10, and the number, shape and size of the process marks are generally determined according to the process requirements. The antenna 201 may be designed to match the structure of the process logo.

In one example, referring to fig. 7, the process identifier multiplexed as the antenna 201 has a cross shape, and the orthographic projection shape of the antenna 201 on the substrate 101 is a cross shape.

In another example, referring to fig. 8, the process identifier multiplexed as the antenna 201 is formed by splicing a plurality of sub identifiers, so that the orthographic projection shape of the antenna 201 on the substrate 101 is also spliced, and the materials of different spliced portions in the antenna 201 may be the same or different.

In the embodiment of the present application, the multiplexing process is identified as the antenna 201 by priority. That is, in the case that the existing process identifier that can be reused as the antenna 201 can meet the use requirement of the electronic device 1000 for the antenna, it is not considered to add a new antenna to the design of the touch cover 10.

In the embodiment of the present application, the antenna 201 may be integrated on the touch substrate 101 of the touch cover 10, and formed by reusing the existing process identifier on the touch cover 10, so that the touch screen 1 has a higher integration level. Therefore, a large enough independent space does not need to be reserved in the electronic equipment to accommodate various types of antennas, and the electronic equipment is light and thin. Moreover, the antenna 201 is integrated on the touch cover 10, and the antenna 201 can have a larger clearance space, thereby improving the communication performance of the antenna 201.

In addition, in an example of independently manufacturing the antenna 201, the antenna 201 may be formed by using the metal conductive layer 102 and/or the transparent conductive layer 104, so that an additional antenna manufacturing process is not required, which is beneficial to improving the production efficiency of the electronic device 1000.

In addition, in the example where the leading-out end of the antenna lead La and the bonding end of the touch signal line are both located in the bonding area a23, the antenna 201 is led out through the antenna lead La and is bonded in the bonding area a23 through the FPC, so that a good bonding effect can be achieved, and the risk of failure of the antenna 03 due to disconnection can be reduced. Thereby contributing to the improvement of the service life and reliability of the antenna 201. Moreover, the antenna lead La and the touch signal line share the same FPC for binding, which not only simplifies the production process of the electronic device 1000 to improve the production efficiency of the electronic device 1000, but also further reduces the space occupation of the antenna 201 related connection structure in the electronic device 1000.

Based on the same inventive concept, the application further provides a touch screen, and the touch screen comprises the touch cover plate in the embodiment. The beneficial effects that can be achieved by the touch screen provided in some embodiments of the present disclosure are the same as those that can be achieved by the touch cover provided in some embodiments, and are not described herein again.

The touch screen provided by some embodiments of the present disclosure may be any device that is applied to the display field, whether in motion (e.g., video) or stationary (e.g., still image), and whether textual or pictorial. More particularly, it is contemplated that the embodiments may be implemented in a variety of electronic devices.

Based on the same inventive concept, the application further provides an electronic device, and the electronic device includes the touch screen in the above embodiment.
