[0058] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0059] The terms "first", "second", etc. in the specification and claims of the present application are used to distinguish similar objects, and are not used to describe a specific order or sequence. It should be understood that the data used in this way can be interchangeable under appropriate circumstances, so that the embodiments of the present application can be implemented in an order other than those illustrated or described here. In addition, the "and / or" in the specification and claims represents at least one of the connected objects, and the character " / " generally represents that the objects associated with each other are in an "or" relationship.

[0060] The following is combined with Figures 1 to 10 , the touch module provided in the embodiment of the present application is described in detail through specific embodiments and application scenarios.

[0061] like Figures 1 to 3 As shown, the touch module in the embodiment of the present application includes a substrate 10, a touch layer 20, an antenna electrode 30 and a pressure electrode 40, wherein the substrate 10 may include a touch area and a pressure detection area, the substrate 10 may be a light-transmitting material piece, the touch layer 20 is arranged on one side of the substrate 10, and the touch layer 20 is located in the touch area, and the touch layer 20 may have a touch electrode. The antenna electrode 30 and the pressure electrode 40 can be arranged in the pressure detection area. The pressure electrode 40 can detect the magnitude of the pressure input into the pressure detection area. The antenna electrode 30 and the pressure electrode 40 are arranged on both sides of the substrate 10 opposite to each other. The orthographic projection of the antenna electrode 30 on the substrate 10 and the orthographic projection of the pressure electrode 40 on the substrate 10 at least partially overlap. For example, the orthographic projection of the antenna electrode 30 on the substrate 10 and the orthographic projection of the pressure electrode 40 on the substrate 10 can completely overlap, so that the antenna electrode 30 and the pressure electrode 40 can form an antenna; the pressure electrode 40 is energized when there is pressure input into the pressure detection area, and the change in resistance generated by the pressure electrode 40 can detect the magnitude of the pressure input into the pressure detection area; the pressure electrode 40 is not energized when there is no pressure input into the pressure detection area, and the pressure electrode 40 can be reused as an antenna radiation layer. The pressure electrode 40 and the antenna electrode 30 form an antenna. At this time, the pressure electrode 40 radiates signals as the radiator of the antenna. When the touch module is applied to the display area of ​​the display module, the substrate 10, the touch layer 20, the antenna electrode 30 and the pressure electrode 40 may be made of light-transmitting materials to facilitate light transmission and avoid affecting the display.

[0062] In the touch module of the present application, the touch layer 20, the antenna electrode 30 and the pressure electrode 40 are integrated together, and the pressure electrode 40 is set as a multiplexed electrode. The pressure electrode 40 is energized when there is pressure input in the pressure detection area, and the pressure can be detected by the pressure electrode 40; the pressure electrode 40 is not energized when there is no pressure input in the pressure detection area, and the pressure electrode 40 can be reused as an antenna radiation layer. The pressure electrode 40 and the antenna electrode 30 form an antenna to improve the radiation performance of the antenna, so that the pressure electrode 40 has different functions in different situations, enhances the use function, reduces the setting of the device, reduces the overall thickness and volume of the device, and is conducive to the thinness and flexibility of the device. During the application process, the touch module can be applied to the display module, and the antenna function and the pressure sensing function are integrated on the touch layer on the display module, and the pressure electrode can time-share multiplex the antenna function, so that the display module can maximize the functional integration, enhance the value of the display module, and reduce the thickness of the display module.

[0063] In some embodiments, when there is pressure input in the pressure detection area, the resistance of the pressure electrode 40 changes, and the magnitude of the pressure applied to the pressure electrode 40 can be detected by the change in the resistance on the pressure electrode 40. For example, the pressure electrode 40 can be connected to a detection unit, and the change in the resistance of the pressure electrode 40 is detected by the detection unit. When the resistance of the pressure electrode 40 changes, a current will pass through the pressure electrode 40, and when the resistance of the pressure electrode 40 does not change, no current will pass through the pressure electrode 40, and then the magnitude of the pressure applied to the pressure electrode 40 is detected by the detection unit.

[0064] In other embodiments, there are multiple antenna electrodes 30 and multiple pressure electrodes 40, and each antenna electrode 30 corresponds to one pressure electrode 40. The specific number can be selected as needed to meet the need of pressure detection and antenna performance requirements.

[0065] Alternatively, if Figure 5 As shown, the pressure electrode 40 is in the shape of a coil. For example, the pressure electrode 40 can be wound to form a coil, and the shape of the coil can be rectangular, polygonal, circular, etc. Each coil is a resistor. When a person's finger applies a certain pressure on the display screen, the substrate will be deformed at the location corresponding to the finger. The cross section of the wire in the coil will change due to the deformation, thereby changing the resistance change of the coil at that location. Using the Wheatstone bridge principle, a weak resistance change can be converted into an electrical signal, such as Figure 6As shown, the second resistor 62 (resistance is R2) is a variable resistor, the third resistor 63 (resistance is R3) and the fourth resistor 64 (resistance is R4) are resistors with known fixed resistances, and the pressure electrode 40 is a coil resistor for pressure sensing. During manufacturing, the variable resistor second resistor 62 is corrected according to the resistance of the pressure electrode 40 (resistance is R1) to make the bridge balanced, that is, R1 / R2=R3 / R4 as shown in the Wheatstone principle. When there is no pressure, the bridge is balanced and there is no current, and no power is consumed; when the coil resistance changes due to pressure, it will cause the bridge detection current to change, thereby obtaining the relationship between pressure and current, and then the pressure applied by the pressure electrode 40 can be detected. Figure 7 As shown in FIG. 1 , when there is pressure input, the pressure electrode 40 acts as a resistor to detect pressure, and the voltage changes as shown in curve a; when there is no pressure input, the pressure electrode 40 is not energized, and no current passes through the pressure electrode 40, and the voltage changes as shown in curve b, serving as the radiation layer of the antenna electrode 30. Figure 4 As shown, the shape of the antenna electrode 30 can be polygonal (such as rectangular), circular, etc., and the antenna electrode 30 can be connected to other structures through the bonding pad 31; Figure 5 As shown, the pressure electrode 40 may be coil-shaped and may be formed by winding a wire. The shape of the coil may be polygonal (such as rectangular), circular, etc. The pressure electrode 40 may be connected to other structures via a bonding pad 41 .

The antenna electrode 30 and the pressure electrode 40 may be located at the key position of the mobile terminal, or at any position around the display screen.

[0076] The embodiment of the present application provides an electronic device, comprising: the display component and the detection unit in the above embodiment, wherein the detection unit is electrically connected to the pressure electrode 40; when there is pressure input in the pressure detection area of ​​the pressure electrode 40, the detection unit can detect the pressure applied to the pressure electrode 40; when there is no pressure input in the pressure detection area of ​​the pressure electrode 40, the pressure electrode 40 is not powered and is multiplexed as an antenna radiation layer, and the pressure electrode 40 and the antenna electrode 30 form an antenna.

[0077] In the embodiments of the present application, Figure 6 As shown, the detection unit may include: a second resistor 62, a third resistor 63, a fourth resistor 64, a detection circuit 65 and a power supply module 66, wherein the second resistor 62 is a variable resistor, the third resistor 63 and the fourth resistor 64 are resistors with known fixed resistances, the first end of the pressure electrode 40 is connected to the first end of the second resistor 62, the second end of the pressure electrode 40 is connected to the first end of the third resistor 63, the second end of the second resistor 62 is connected to the first end of the fourth resistor 64, and the second end of the third resistor 63 is connected to the second end of the fourth resistor 64; the first end of the detection circuit 65 is electrically connected to the first end of the pressure electrode 40, the second end of the detection circuit 65 is electrically connected to the second end of the third resistor 63, the first end of the power supply module 66 is electrically connected to the second end of the pressure electrode 40, and the second end of the power supply module 66 is electrically connected to the second end of the second resistor 62.
