Description

Technical Field

[0001] This application relates to the field of touch technology. More specifically, this application relates to a touch sensor, a touch panel, and an electronic device. Background Technology

[0002] Existing capacitive touch sensor designs typically use M+N capacitive electrode units (where M is the number of driving electrodes and N is the number of sensing electrodes), and each driving electrode and each sensing electrode is designed as a strip electrode unit. This means that after one round of square wave scanning, the existing capacitive touch sensor can only obtain data from one intersection point. Due to electromagnetic interference generated by external devices (such as LEDs), users cannot determine the accuracy of this focal point data. Summary of the Invention

[0039] The specific embodiments of this application will be further described below with reference to the accompanying drawings.

[0040] <Touch Sensor>

[0041] like Figure 4 As shown, the first aspect of this application provides a touch sensor, in Figure 4 In this context, the touch sensor includes:

[0042] At least one driving electrode TX and at least one sensing electrode RX, each driving electrode TX comprising a first electrode unit 10 and a second electrode unit 20, as detailed below. Figure 1 The first electrode unit 10 includes at least one first conductive portion 11, the first conductive portion 11 having a first connecting hole 111 and a first connecting portion 112, such as... Figure 2 As shown; the second electrode unit 20 includes at least one second conductive portion 21, the second conductive portion 21 having a second connecting hole 211 and a second connecting portion 212, as shown. Figure 3 As shown. In this configuration, at least one first conductive part 11 corresponds to at least one second conductive part 21. The first connecting part 112 of the first conductive part 11 is connected to the second connecting hole 211 of the corresponding second conductive part 21, and the second connecting part 212 of the second conductive part 21 is connected to the first connecting hole 111 of the corresponding first conductive part 11.

[0043] In some implementations, such as Figure 2 As shown, the first connecting hole 111 has a first opening 1111, and the second connecting hole 211 has a second opening 2111.

[0044] In some embodiments, in each of the first conductive portions 11, the first connecting portion 112 has a first sidewall 1121 disposed toward the first connecting hole 111, and the first sidewall 1121 is located inside the first connecting hole 111; in each of the second conductive portions 21, the second connecting portion 212 has a second sidewall 2121 disposed toward the second connecting hole 211, and the second sidewall 2121 is located inside the second connecting hole 211.

[0045] In some embodiments, the first conductive portion 11 is recessed inward from the first sidewall 1121 to form a third connecting hole 113, and a third connecting portion 1122 is formed on the first connecting portion 112; the second conductive portion 21 is recessed inward from the second sidewall 2121 to form a fourth connecting hole 213, and a fourth connecting portion 2122 is formed on the second connecting portion 212; wherein,

[0046] The third connecting portion 1122 of the first conductive portion 11 is connected to the fourth connecting hole 213 of the corresponding second conductive portion 21, and the fourth connecting portion 2122 of the second conductive portion 21 is connected to the third connecting hole 113 of the corresponding first conductive portion 11.

[0047] In some embodiments, there are multiple first conductive parts 11 and multiple second conductive parts 21, with multiple first conductive parts 11 connected in sequence and multiple second conductive parts 21 connected in sequence.

[0048] In some embodiments, a third conductive part 30 is provided at one end of the first conductive part 11, and a fourth conductive part 40 is provided at the other end.

[0049] In two adjacent first conductive portions 11, the third conductive portion 30 of one first conductive portion 11 is connected to the fourth conductive portion 40 of the other first conductive portion 11.

[0050] In some embodiments, a fifth conductive part 50 is provided at one end of the second conductive part 21, and a sixth conductive part 60 is provided at the other end.

[0051] In two adjacent first conductive portions 11, the fifth conductive portion 50 of one second conductive portion 21 is connected to the sixth conductive portion 60 of the other second conductive portion 21.

[0052] In some embodiments, the third conductive part 30, the fourth conductive part 40, the fifth conductive part 50, and the sixth conductive part 60 are all rod-shaped.

[0053] In some implementations, such as Figure 4 As shown, there are multiple driving electrodes TX and multiple sensing electrodes RX. For example, there are 6 driving electrodes TX and 6 first electrode units 10, as shown... Figure 4 In the T0-A, T1-A, T2-A, T3-A, T4-A, and T5-A, the number of the second electrode units 20 is 6, such as... Figure 4 The components are T0-B, ​​T1-B, T2-B, T3-B, T4-B, and T5-B; the number of the sensing electrodes RX is 5, as shown below. Figure 4 R0, R1, R2, R3, and R4 in the equation.

[0054] In practical applications, the touch sensor can operate as follows (see details). Figure 4 ):

[0055] The first electrode unit T0-A of the first driving electrode TX receives a 300kHz scan signal and begins scanning. After scanning is completed, the second electrode unit T0-B of the first driving electrode receives a 500kHz scan signal and begins scanning. The scanning of all remaining driving electrodes is performed in the same way as the first driving electrode, and so on asynchronously, so that the scanning operations of the first electrode unit and the second electrode unit of the same driving electrode do not occur simultaneously on the same basic unit.

[0056] The touch panel of this application can also operate in the following manner (see...) Figure 3-5 ):

[0057] The first electrode unit T0-A of the first driving electrode receives a 300kHz scan signal and begins scanning. After scanning is completed, the second electrode unit T5-B of the sixth driving electrode receives a 500kHz scan signal and begins scanning. After scanning is completed, the first electrode unit T1-A of the second driving electrode receives a 300kHz scan signal and begins scanning. After scanning is completed, the second electrode unit T4-B of the fifth driving electrode receives a 500kHz scan signal and begins scanning. The scanning of all remaining driving electrodes is performed asynchronously in sequence according to the above scanning method.

[0058] In some implementations, such as Figure 5 As shown, each unit of the sensing electrode RX is rhomboid. In other embodiments, it may also be other shapes.

[0059] In some embodiments, the first electrode unit 10 and the second electrode unit 20 are integrated like the Bagua (Eight Trigrams) to form a rhombus pattern. This can reduce the inherent parasitic capacitance of the driving electrode TX and the sensing electrode RX due to overlap, which is beneficial for the data received by the touch sensor to be in the optimal position, rather than at the edge or extreme.

[0060] <Touch Panel>

[0061] A second aspect of this application provides a touch panel including a touch chip and a touch sensor provided in the first aspect of this application, wherein the touch chip and the touch sensor are electrically connected.

[0064] The present application and its embodiments have been described above. This description is not restrictive, and the accompanying drawings are only one embodiment of the present application. The actual structure is not limited to this. In conclusion, if a person skilled in the art is inspired by this description and designs a similar structure and embodiment without departing from the spirit of the present application, such design should fall within the protection scope of the present application.
