[0045] The embodiment of the present application provides a touch module and a smart device including the touch module. The touch module is provided with a switch between touch electrodes, and the electrical connection relationship between the touch electrodes can be changed by changing the working state of the switch, thereby changing the sensing distance of the touch module, so that the touch module can be applied to various sensing scenarios.

[0046] Embodiment 1

[0047] See also Figure 1 The smart device 1 in this embodiment includes a touch module 10 and a display module 20 which are electrically connected to each other. The touch module 10 is used to identify the user's touch operation, and the display module 20 is used to display corresponding image content based on the touch operation.

[0048] The smart device 1 is a device that integrates display function and touch function, such as a smart phone, a tablet, a laptop, a car multimedia device, a smart home appliance, etc. The touch module 10 can be an out-cell touch module or an in-cell touch module. The touch module 10 can be used to sense contact (touch objects, including fingers, stylus, etc., directly contact the touch module) touch operation and non-contact (or suspended, the touch object does not directly contact the touch module) touch operation. The display module 20 can be, for example, a liquid crystal display (LCD), a micro-light emitting diode (Micro-LED) display, an organic light emitting diode (OLED) display, etc.

[0049] In this embodiment, the touch module 10 is taken as an example of a plug-in touch module to illustrate the structure and function of the touch module 10 .

[0050] See also Figure 2 The touch module 10 of this embodiment includes a substrate 11, a plurality of touch electrodes 12, a plurality of first switches 13, a plurality of second switches 14, and a touch chip (IC) 15. The touch IC 15 includes a switch control circuit 151 and a touch control circuit 152. The switch control circuit 151 is electrically connected to each first switch 13 and each second switch 14. The touch control circuit 152 is electrically connected to each touch electrode 12. The plurality of touch electrodes 12, the plurality of first switches 13, the plurality of second switches 14, and the touch IC 15 are located on the same surface 111 of the substrate 11.

[0051] The surface 111 of the substrate 11 has an area located in the display area AA and an area located in the non-display area NA, and the non-display area NA surrounds and connects to the periphery of the display area AA. The display area AA is rectangular, and the surface 111 is also rectangular. A plurality of touch electrodes 12 are located in the display area AA of the surface 111. A plurality of first switches 13, a plurality of second switches 14, and a touch IC 15 are located in the non-display area NA of the surface 111.

[0052] In the present embodiment, the substrate 11 is a light-transmitting insulating material (for example, glass), and each touch electrode 12 is a transparent conductive material (for example, indium tin oxide). The display area AA is an area where the smart device 1 can display images through light, and the non-display area NA is a non-light-transmitting frame area of ​​the smart device 1, which is usually used for conductive circuit arrangement. In other embodiments of the present application, the surface 111 and the display area AA may not be rectangular, for example, they may be circular or other irregular shapes. In other embodiments of the present application, the arrangement of the display area AA and the non-display area NA may be different, for example, the display area AA and the non-display area NA are arranged side by side and spliced ​​to form the surface 111 of the substrate 11.

[0053] In this embodiment, all the touch electrodes 12 on the substrate 11 are divided into two groups, each group includes a plurality of touch electrodes 12. One group of touch electrodes 12 is used as driving electrodes 121, and the other group of touch electrodes 12 is used as sensing electrodes 122. That is, a plurality of driving electrodes 121 and a plurality of sensing electrodes 122 are provided on the substrate 11.

[0054] Each driving electrode 121 is arranged in the same layer, each sensing electrode 122 is arranged in the same layer, each driving electrode 121 and each sensing electrode 122 are stacked and spaced from each other (for example, a light-transmitting insulating layer is formed between the driving electrode 121 and the sensing electrode 122, which is not shown in the figure). Each driving electrode 121 is a strip electrode. Each driving electrode 121 is arranged in parallel and spaced in sequence along the first direction X, and each driving electrode 121 extends along the second direction Y. Each sensing electrode 122 is a strip electrode. Each sensing electrode 122 is arranged in parallel and spaced in sequence along the second direction Y, and each sensing electrode 122 extends along the first direction X. The first direction X is perpendicular to the second direction Y. In this embodiment, the first direction X and the second direction Y are respectively parallel to one of the sides of the surface 111.

[0055] In this embodiment, each first switch 13 is electrically connected to two adjacently arranged driving electrodes 121. Different first switches 13 are connected to different driving electrodes 121. That is, a first switch 13 is connected between each two adjacent driving electrodes 121. For example, along the first direction X, a first switch 13 is connected between the first driving electrode 121 and the second driving electrode 121, a first switch 13 is connected between the second driving electrode 121 and the third driving electrode 121...a first switch 13 is connected between the n-1th driving electrode 121 and the nth driving electrode 121.

[0056] Each second switch 14 is electrically connected to two adjacently arranged sensing electrodes 122. Different second switches 14 are connected to different sensing electrodes 122. That is, a second switch 14 is connected between every two adjacent sensing electrodes 122. For example, along the second direction Y, a second switch 14 is connected between the first sensing electrode 122 and the second sensing electrode 122, a second switch 14 is connected between the second sensing electrode 122 and the third sensing electrode 122, and so on. A second switch 14 is connected between the m-1th sensing electrode 122 and the mth sensing electrode 122.

[0057] The switch control circuit 151 is used to output a first signal to each first switch 13. The first signal is used to control the working state of the first switch 13. When the first switch 13 is in different working states, the electrical connection relationship between the two driving electrodes 121 connected thereto is different. Therefore, the switch control circuit 151 controls the working state of the first switch 13 through the first signal to control the electrical connection relationship between adjacent driving electrodes 121.

[0058] The switch control circuit 151 is used to output a second signal to each second switch 14. The second signal is used to control the working state of the second switch 14. When the second switch 14 is in different working states, the electrical connection relationship between the two sensing electrodes 122 connected thereto is different. Therefore, the switch control circuit 151 controls the working state of the second switch 14 through the second signal to control the electrical connection relationship between adjacent sensing electrodes 122.

[0059] Each first switch 13 and each second switch 14 is a transistor, such as a triode or a metal-oxide-semiconductor field-effect transistor (MOS transistor). The first signal and the second signal are voltage signals. The switch control circuit 151 controls the first switch 13 to be turned on or off by the first signal to control the electrical connection relationship between adjacent driving electrodes 121, and controls the second switch 14 to be turned on or off by the second signal to control the electrical connection relationship between adjacent sensing electrodes 122. In this embodiment, each first switch 13 and each second switch 14 are MOS transistors.

[0060] The gate of each first switch 13 is electrically connected to the switch control circuit 151, and the source and drain are electrically connected to two adjacent driving electrodes 121 respectively. Each first switch 13 has a first turn-on voltage. When the amplitude of the first signal is greater than or equal to the first turn-on voltage, the first switch 13 is in the on state, at which time the source and drain of the first switch 13 are turned on, and the two adjacent driving electrodes 121 connected to the first switch 13 are in the electrically conductive state. When the amplitude of the first signal is less than the first turn-on voltage, the first switch 13 is in the off state, at which time the source and drain of the first switch 13 are not turned on, and the two adjacent driving electrodes 121 connected to the first switch 13 are in an electrically insulated state.

[0061] The gate of each second switch 14 is electrically connected to the switch control circuit 151, and the source and drain are electrically connected to two adjacent sensing electrodes 122, respectively. Each second switch 14 has a second turn-on voltage. When the amplitude of the second signal is greater than or equal to the second turn-on voltage, the second switch 14 is in the on state, at which time the source and drain of the second switch 14 are turned on, and the two adjacent sensing electrodes 122 connected to the second switch 14 are in the electrically turned-on state. When the amplitude of the second signal is less than the second turn-on voltage, the second switch 14 is in the off state, at which time the source and drain of the second switch 14 are not turned on, and the two adjacent sensing electrodes 122 connected to the second switch 14 are in an electrically insulated state.

[0062] In this embodiment, the first turn-on voltages of the first switches 13 are the same, the second turn-on voltages of the second switches 14 are the same, and the first turn-on voltage is the same as the second turn-on voltage.

[0063] The switch control circuit 151 can control the working state of each first switch 13 and each second switch 14 by controlling the amplitude of the first signal output to each first switch 13 and the amplitude of the second signal output to each second switch 14, thereby controlling the electrical connection relationship between each touch electrode 12 on the substrate 11.

[0064] The touch control circuit 152 includes a driving unit 1521 and a sensing unit 1522. The driving unit 1521 is electrically connected to each driving electrode 121, and is used to output a driving signal to each driving electrode 121. The sensing unit 1522 is electrically connected to each sensing electrode 122, and is used to receive a sensing signal from each sensing electrode 122, and recognize a user's touch operation according to the sensing signal.

[0065] In this embodiment, the touch module 10 is a capacitive touch module, and the sensing signal is a capacitance signal. That is, the driving unit 1521 outputs a driving signal to each driving electrode 121, and when there is a touch operation, a capacitance change occurs on the plurality of sensing electrodes 122 located at the touch position, and the capacitance change is received by the sensing unit 1522 as the sensing signal for identifying the touch operation.

[0066] In this embodiment, the touch module 10 is mainly used in non-contact touch operation scenarios to identify what kind of gestures the user makes in the air and what kind of actions (such as drawing a circle or sliding in a straight line) the user performs. The touch module 10 has a sensing distance. The touch module 10 can identify touch operations within the sensing distance, but it is difficult to identify touch operations outside the sensing distance.

[0067] The sensing distance of the touch module 10 is related to the area of ​​the touch electrode 12. Figure 4 , Figure 4 Figure (a) shows the electric field generated by a single touch electrode 2 , which enables the touch module to have a sensing distance D1 . Figure 4 Figure (b) shows the electric field generated when two adjacent touch electrodes 2 are electrically connected. At this time, the two touch electrodes 2 electrically connected to each other are equivalent to a touch electrode 3. This is equivalent to doubling the area of ​​a single touch electrode in the touch module. At this time, the electric field generated by the two electrically connected touch electrodes 2 (i.e., touch electrodes 3) increases the sensing distance of the touch module to D2, where D2>D1. Figure 4 It can be seen that the sensing distance D2 is significantly different from the sensing distance D1 , so changing the electrical connection relationship between the touch electrodes can change the sensing distance of the touch module.

[0068] The touch module 10 of this embodiment is provided with a plurality of first switches 13, a plurality of second switches 14 and a switch control circuit 151, and the switch control circuit 151 controls the working state of each first switch 13 and each second switch 14, so as to adjust the electrical connection relationship between each touch electrode 12. In the touch module 10, the touch electrodes 12 electrically connected to each other are collectively equivalent to one touch electrode. Therefore, adjusting the electrical connection relationship between each touch electrode 12 is equivalent to adjusting the area of ​​a single touch electrode in the touch module 10, so as to adjust the sensing distance of the touch module 10. For example, when it is necessary to reduce the sensing distance, the number of touch electrodes 12 electrically connected to each other is reduced; when it is necessary to increase the sensing distance, the number of touch electrodes 12 electrically connected to each other is increased. For different touch scenarios, the touch module is required to have different sensing distances. The sensing distance of the touch module 10 of the embodiment of the present application is adjustable and can be applied to a variety of different touch scenarios.

[0069] Figure 2 In the touch module 10 shown, the first switches 13 are arranged in sequence along the first direction X, and the second switches 14 are arranged in sequence along the second direction Y. The first switches 13 and the second switches 14 are located on the surface 111 of the substrate 11 independently of the touch IC 15 .

[0070] See also Figure 3 In at least one modified embodiment of the present application, each first switch 13 and each second switch 14 may be integrated into the touch control IC 15. That is, the touch control IC 15 includes a plurality of first switches 13, a plurality of second switches 14, a switch control circuit 151, and a touch control circuit 152. In other modified embodiments of the present application, the touch control IC 15 may integrate one of the plurality of first switches 13 and the plurality of second switches 14.

[0071] The modified embodiment described above can achieve all the beneficial effects of the first embodiment, and on this basis, the circuit layout in the non-display area NA can be further optimized.

[0074] In this embodiment, each touch electrode 12 has the same structure and function, and there is no distinction between drive electrodes and sensing electrodes. All touch electrodes 12 are arranged in an array including multiple rows and multiple columns. Each row in the array includes multiple touch electrodes 12, and each column includes multiple touch electrodes 12. The number of touch electrodes 12 in each row is the same, and the number of touch electrodes 12 in each column is the same.

[0079] Each second switch 14 is respectively connected to two adjacently arranged second wires 172. Each third switch 16 is connected to one of the second wires 172 and the touch control circuit 152. In this embodiment, the touch control circuit 152 includes a plurality of touch control units 1523 connected in parallel. Each touch control unit 1523 is electrically connected to a second wire 172.

[0081] The working state control method of each first switch 13 and each second switch 14 is as described in the first embodiment and will not be described in detail. The switch control circuit 151 can control the working state of each first switch 13 and each second switch 14 by controlling the amplitude of the first signal output to each first switch 13 and the amplitude of the second signal output to each second switch 14, thereby controlling the electrical connection relationship between each touch electrode 12 on the substrate 11.
