Description

Technical Field

[0001] This application relates to the field of touch sensor technology, and in particular to a touch sensor, touch panel and electronic device. Background Technology

[0002] Touchscreens, characterized by low mechanical loss and small size, have been widely used in various electronic products. Touchscreens include resistive and capacitive touchscreens. With technological advancements, self-capacitive touchscreens are increasingly widely used in various devices. During touch detection, a self-capacitive touchscreen sequentially detects the horizontal and vertical touch sensor channel arrays. Based on the change in capacitance before and after a touch, it determines the horizontal and vertical coordinates of the touch position, which are then combined to form planar coordinates. However, when used in electronic devices such as laptops, the larger size of the touch panel drastically increases the number of touch sensor channels required, leading to increased design complexity and cost for the touch sensors.

[0003] Therefore, a solution is needed to improve the above problems. Summary of the Invention

[0004] This application is made in view of at least one of the above-mentioned technical problems existing in the prior art. According to one aspect of this application, a touch sensor is provided, the touch sensor comprising:

[0005] The first touch sensing channel is arranged along a first direction in the touch area. The first touch sensing channel includes a first preset number of adjacent first touch channels and a number of non-adjacent first touch channels that are the same as the adjacent first touch channels. Each of the adjacent first touch channels is connected to one of the non-adjacent first touch channels.

[0006] The second touch sensing channel is arranged along the second direction in the touch area. The second touch sensing channel includes a second preset number of adjacent second touch channels and a number of non-adjacent second touch channels with the same number as the second touch channel. Each of the adjacent second touch channels is connected to one of the non-adjacent second touch channels.

[0007] The second direction intersects with the first direction.

[0008] In some embodiments, the first of all adjacent first touch channels is connected to the penultimate non-adjacent first touch channel among all non-adjacent first touch channels;

[0009] The second of all adjacent first touch channels is connected to the penultimate non-adjacent first touch channel among all non-adjacent first touch channels;

[0010] This process continues until all the first touch channels are connected.

[0011] In some embodiments, the adjacent first touch channel and the non-adjacent first touch channel, as well as the adjacent second touch channel and the non-adjacent second touch channel, adopt any of the following connection methods: one-to-two connection method, one-to-three connection method, one-to-four connection method, or one-to-five connection method.

[0012] In some embodiments, when the adjacent first touch channel and the non-adjacent first touch channel are connected in a one-to-two manner, the touch sensor includes:

[0013] When the sequence number of any first touch channel is k and the total number of first touch channels is n, then when k ≦ n / 3, the arbitrary first touch channel is connected to the second-to-last first touch channel; when k > n / 3, the arbitrary first touch channel is connected to the second-to-last first touch channel, where k, n, and p are all positive integers.

[0014] In some embodiments, the first of all adjacent second touch channels is connected to the penultimate non-adjacent second touch channel among all non-adjacent second touch channels;

[0015] The second of all adjacent second touch channels is connected to the penultimate non-adjacent second touch channel among all non-adjacent second touch channels;

[0016] This process continues until all second touch channels are connected.

[0017] In some embodiments, when the adjacent second touch channel and the non-adjacent second touch channel are connected in a one-to-two manner, the touch sensor includes:

[0018] When the sequence number of any second touch channel is i and the total number of all first touch channels is m, if i ≤ m / 3, then any second touch channel is connected to the second touch channel from the 2p-1th to the end; if i > m / 3, then any second touch channel is connected to the second touch channel from the 2pth to the end, where i, m, and p are all positive integers.

[0019] In some embodiments, the first touch sensing channel is connected to a detection circuit via a signal line; wherein the detection circuit senses the mutual capacitance change between the first touch channel and the second touch channel, and determines the touch position based on the position of the first touch channel and the position of the second touch channel.

[0020] In some embodiments, when the detection circuit senses a change in mutual capacitance between the first touch channel and the second touch channel, it is further configured to:

[0021] Determine the positions of the adjacent first touch channels, the non-adjacent first touch channels, the adjacent second touch channels, and the non-adjacent second touch channels that have changed;

[0022] Delete the positions of the non-adjacent first touch channel and the non-adjacent second touch channel;

[0023] The touch position is determined based on the positions of the adjacent first touch channels and the adjacent second touch channels.

[0024] In some embodiments, each of the first touch channels and each of the second touch channels are electrically isolated from each other.

[0025] In some embodiments, the first touch sensing channel is located in the first sensing layer, the second touch sensing channel is located in the second sensing layer, the first sensing layer is superimposed on the second sensing layer, or the second sensing layer is superimposed on the first sensing layer.

[0026] In some embodiments, the first direction is the X-axis direction and the second direction is the Y-axis direction; or, the first direction is the Y-axis direction and the second direction is the X-axis direction.

[0027] Another embodiment of this application provides a touch panel, which includes the aforementioned touch sensor.

[0028] In another aspect, this application provides an electronic device, which includes the aforementioned touch panel.

[0029] The touch sensor in this application embodiment connects each of the adjacent first touch channels to a non-adjacent first touch channel and each of the adjacent second touch channels to a non-adjacent second touch channel. This allows the touch position to be located based on the adjacent and non-adjacent relationships between channels when a touch event occurs, without increasing the number of first and second touch channels. This reduces the design difficulty and manufacturing cost of the touch sensor. Attached Figure Description

[0039] To enable those skilled in the art to better understand the technical solutions of the embodiments of this application, the application will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0040] like Figure 1 The diagram shown is a structural schematic of a touch sensor 100 in conventional technology. Figure 1 In this diagram, Tx represents the transmit channel, Rx represents the receive channel, and Tx1 to Tx2 represent the transmit channel. n Represents the 1st to the nth transmission channels, Rx1 to Rx n This represents the 1st to the nth receiving channel. The transmitting channel Tx is located below the touch sensor, with different sensor channels separated by a small gap. The receiving channel Rx is located above the sensor, with different sensor channels separated by a larger gap. The transmitting and receiving channels are isolated by an insulating layer. A mutual capacitance C is formed between the transmitting channel Tx and the receiving channel Rx. m Each transmit / receive channel requires a dedicated transmit / receive channel Tx / Rx connected to a detection circuit (Integrated Circuit Chip, IC) (not shown in the diagram) to detect the mutual capacitance C between the touch sensors Tx / Rx. m The dynamic changes. When a finger or other external conductor touches the surface of the touch device, the mutual capacitance C between Tx / Rx changes. mA certain change will occur; the corresponding channel Tx / Rx of the touch sensor will detect the mutual capacitance C at this time. m The changes in the finger's touch position are detected by the sensor.

[0041] Depend on Figure 1 As can be seen, each transmitting / receiving electrode requires a dedicated Tx / Rx detection channel connected to the detection circuit. When this design is used in touchscreens for laptops and larger, the touch panel size is relatively large (e.g., 14 inches and above), requiring an increase in the number of touch sensor channels (Tx / Rx) to meet the performance requirements of medium to large-sized touchscreens. This places higher demands on the number of channels in the detection circuit, increasing the design complexity, size, and cost of the detection circuit.

[0042] Based on at least one of the aforementioned technical problems, this application provides a touch sensor, comprising: a first touch sensing channel arranged along a first direction within a touch area, the first touch sensing channel including a first preset number of adjacent first touch channels and a number of non-adjacent first touch channels having the same number as the adjacent first touch channels, and each of the adjacent first touch channels being connected to one of the non-adjacent first touch channels; and a second touch sensing channel arranged along a second direction within the touch area, the second touch sensing channel including a second preset number of adjacent second touch channels and a number of non-adjacent second touch channels having the same number as the second touch channels, and each of the adjacent second touch channels being connected to one of the non-adjacent second touch channels; wherein the second direction intersects the first direction. The touch sensor in this application embodiment connects each of the adjacent first touch channels to a non-adjacent first touch channel and each of the adjacent second touch channels to a non-adjacent second touch channel. This allows the touch position to be located based on the adjacent and non-adjacent relationships between channels when a touch event occurs, without increasing the number of first and second touch channels. This reduces the design difficulty and manufacturing cost of the touch sensor.

[0043] Figure 2 A schematic diagram of the structure of a touch sensor according to an embodiment of this application is shown; as follows: Figure 2 As shown, the touch sensor according to the embodiments of this application may include a first touch sensing channel 201 and a second touch sensing channel 202.

[0044] In one embodiment of this application, a first touch sensing channel 201 is arranged along a first direction within a touch area. The first touch sensing channel 201 includes a first preset number of adjacent first touch channels and a number of non-adjacent first touch channels that are the same as the adjacent first touch channels. Each of the adjacent first touch channels is connected to one of the non-adjacent first touch channels.

[0045] The first direction can be the X-axis direction or the Y-axis direction.

[0046] In one embodiment of this application, the first of all adjacent first touch channels is connected to the penultimate non-adjacent first touch channel among all non-adjacent first touch channels;

[0047] The second of all adjacent first touch channels is connected to the penultimate non-adjacent first touch channel among all non-adjacent first touch channels;

[0048] This process continues until all the first touch channels are connected.

[0049] In one embodiment of this application, the adjacent first touch channel and the non-adjacent first touch channel, as well as the adjacent second touch channel and the non-adjacent second touch channel, are connected in any of the following ways: a one-to-two connection, a one-to-three connection, a one-to-four connection, or a one-to-five connection. This application does not limit the connection method. Those skilled in the art will understand that in other embodiments, one-to-six, one-to-seven, and other connection methods can still be implemented in this application.

[0050] In this context, the "one-to-two" connection method refers to a situation where non-adjacent first touch channels are separated by one channel, and adjacent first touch channels are sequentially connected to non-adjacent first touch channels. For example, combining... Figure 2 Tx n Tx (n-2) With Tx (n-4) To ensure that the first touch channel is not adjacent, Tx n With Tx (n-2) Between, Tx (n-2) With Tx (n-4) Each of the three touch channels is separated by one channel. Similarly, the one-to-three connection method means that there are two channels between the non-adjacent first touch channels, and the adjacent first touch channels are connected to the non-adjacent first touch channels in sequence; the one-to-four connection method means that there are three channels between the non-adjacent first touch channels, and the adjacent first touch channels are connected to the non-adjacent first touch channels in sequence; the one-to-five connection method means that there are four channels between the non-adjacent first touch channels, and the adjacent first touch channels are connected to the non-adjacent first touch channels in sequence; and so on.

[0051] Specifically, taking the adjacent first touch channel and the non-adjacent first touch channel as an example of a one-to-two connection, when the adjacent first touch channel and the non-adjacent first touch channel are connected in a one-to-two manner, the touch sensor includes:

[0052] When the sequence number of any first touch channel is k and the total number of first touch channels is n, then when k ≦ n / 3, the arbitrary first touch channel is connected to the second-to-last first touch channel; when k > n / 3, the arbitrary first touch channel is connected to the second-to-last first touch channel, where k, n, and p are all positive integers.

[0053] The first touch channel can be a transmitting channel or a receiving channel. This embodiment will use the first touch channel as a transmitting channel as an example.

[0054] In one specific embodiment, continue to combine Figure 2 The launch channels are connected in a one-to-two configuration. Assuming the total number of launch channels is n, Tx k Let be any one of the transmission channels. The connection relationships between the transmission channels are as follows:

[0055] When k≤[n / 3]

[0056] Connect the first launch channel Tx1 with the last launch channel Tx n connect,

[0057] The second launch channel Tx2 and the third-to-last launch channel Tx (n-2) connect,

[0058] The third launch channel Tx3 and the fifth-to-last launch channel Tx (n-4) connect,

[0059] The fourth launch channel Tx4 and the seventh launch channel from the bottom Tx (n-6) connect,

[0060] And so on, for the [n / 3]th transmission channel Tx 4[n / 3] With the (n-2(k-1))th transmission channel Tx (n-2(k-1)) connect;

[0061] When k > [n / 3]

[0062] The [n / 3]+1th transmission channel Tx [n / 3]+1 With the penultimate launch channel Tx (n-1) Connected,

[0063] The [n / 3]+2th transmission channel Tx [n / 3]+2With the fourth-to-last transmission channel Tx (n-3) Connected,

[0064] This process continues until all transmission channels are connected.

[0065] The above states that k≤[n / 3] means that k is a positive integer not greater than n / 3, and k>[n / 3] means that k is a positive integer greater than n / 3.

[0066] In order to clearly state this application, Figure 2 The connection shown in the image is merely illustrative; Tx k This indicates any channel, but it's placed at the position of the largest ordinal transmission channel in k ≤ [n / 3], rather than indicating a specific transmission channel. Also, Tx6 and Tx in the diagram... k7 ...Tx p These figures are merely for illustrating the embodiments of this application.

[0067] In this application, by connecting and combining the touch sensor transmission channels in the above-mentioned pattern, the number of transmission channels can be reduced by about half.

[0068] Similarly, the same technical effect can be achieved by using a one-to-three connection method, a one-to-four connection method, a one-to-five connection method, and so on, up to a one-to-N connection method for the transmission channel.

[0069] In one embodiment of this application, a second touch sensing channel 202 is arranged along a second direction within the touch area. The second touch sensing channel 202 includes a second preset number of adjacent second touch channels and a number of non-adjacent second touch channels having the same number as the second touch channels. Each of the adjacent second touch channels is connected to one of the non-adjacent second touch channels.

[0070] The second direction is either the Y-axis direction or the X-axis direction.

[0071] The second direction intersects with the first direction.

[0072] In one example, the first of all adjacent second touch channels is connected to the penultimate of all non-adjacent second touch channels;

[0073] The second of all adjacent second touch channels is connected to the penultimate non-adjacent second touch channel among all non-adjacent second touch channels;

[0074] This process continues until all second touch channels are connected.

[0075] In one example, when the adjacent second touch channel and the non-adjacent second touch channel are connected in a one-to-two configuration, the touch sensor includes:

[0076] When the sequence number of any second touch channel is i and the total number of all first touch channels is m, if i ≤ m / 3, then any second touch channel is connected to the second touch channel from the 2p-1th to the end; if i > m / 3, then any second touch channel is connected to the second touch channel from the 2pth to the end, where i, m, and p are all positive integers.

[0077] Combination Figure 3 ,and Figure 2 The same principle applies to the illustrated embodiment; we will continue with the example of a one-to-two connection method for the receiving channels. Assume the total number of receiving channels is m, and i is any one receiving channel:

[0078] When i ≤ [m / 3]

[0079] Connect the first receiving channel Rx1 with the last receiving channel Rx m connect,

[0080] The second receiving channel Rx2 and the third-to-last receiving channel Rx (m-2) connect,

[0081] The third receiving channel Rx3 and the fifth-to-last receiving channel Rx (m-4) connect,

[0082] And so on, for the [m / 3]th receiving channel Rx [m / 3] With the Rx (n-2(i-1)) connect;

[0083] When i > [m / 3]

[0084] The [m / 3]+1th receiving channel Rx [m / 3]+1 With the penultimate receiving channel Rx (m-1) Connected,

[0085] The [m / 3]+2nd receiving channel Rx [m / 3]+2 With the fourth-to-last receiving channel Rx (m-3) Connected,

[0086] This process continues until all receiving channels are connected.

[0087] Wherein, m and n may be equal or unequal, depending on the touch panel in which the touch sensor is applied in this application.

[0088] This application combines the touch sensor channels according to the above-mentioned pattern, which can reduce the number of receiving channels by about half.

[0089] Those skilled in the art will understand that the above scheme is merely a one-to-two arrangement of the touch sensor's transmit / receive channels. Based on the same principle, one-to-three, one-to-four, ... one-to-N schemes are also within the scope of protection of this patent, and will not be elaborated here. The connection method is as described above and will not be repeated here.

[0090] In one embodiment of this application, the first touch sensing channel is connected to a detection circuit via a signal line; wherein, the detection circuit senses the mutual capacitance change between the first touch channel and the second touch channel, and determines the touch position based on the position of the first touch channel and the position of the second touch channel.

[0091] In one example, when the detection circuit senses a change in mutual capacitance between the first touch channel and the second touch channel, it is further configured to:

[0092] Determine the positions of the adjacent first touch channels, the non-adjacent first touch channels, the adjacent second touch channels, and the non-adjacent second touch channels that have changed;

[0093] Delete the positions of the non-adjacent first touch channel and the non-adjacent second touch channel;

[0094] The touch position is determined based on the positions of the adjacent first touch channels and the adjacent second touch channels.

[0095] The following describes how the detection circuit of this application can be used to achieve touch position detection without increasing the number of transmit / receive channels.

[0096] To ensure necessary touch accuracy, devices such as laptops often design a single transmit / receive channel width of approximately 4.5mm. Since the width of a human finger is approximately 10mm, in normal touch events, it's unlikely that only one sensor transmit or receive channel will be touched; instead, 2-4 transmit or receive channels will be touched simultaneously.

[0097] To simplify the analysis, the following is... Figure 4 As shown, assuming a finger simultaneously touches three transmission channels Tx1, Tx2, and Tx3, the detection circuit can easily detect changes in the mutual capacitance of these three channels. However, at this time, due to the mutual capacitance changes between Tx1 and Tx3... n Tx2 and Tx (n-2 Tx3 and Tx (n-4) If they are interconnected, the detection circuit will also detect Tx. n Tx (n-2) With Tx(n-4) Capacitance changes also occur, at which point the following will appear: Figure 5 The following are examples: Tx1, Tx2, Tx3, Tx, Tx (n-2) With Tx (n-4) Touch actions may occur on all transmission channels. Logically, touch events must occur on consecutively arranged transmission channels. Combining this with the adjacent positions of the transmission channels, we can determine that the actual touch occurred at adjacent positions Tx1, Tx2, and Tx3. Figure 6 As shown, non-adjacent transmission channels Tx can therefore be excluded. n ,Tx (n-2) and Tx (n-4) The possibility of being touched allows for accurate positioning of the touch location.

[0098] Similarly, assuming that the fingers touch simultaneously as follows: Figure 7 Tx shown n Tx (n-1) and Tx (n-2) With three transmission channels, the detection circuit can obviously detect Tx very easily. n Tx (n-1) and Tx (n-2) The capacitance changes in all three channels. However, at this time, due to the capacitance changes between Tx1 and Tx... n Tx6 and Tx (n-1) Tx2 and Tx (n-2) If they are interconnected, the detection circuit will simultaneously detect capacitance changes in Tx1, Tx2, and Tx6, resulting in the following: Figure 8 Tx shown n Tx (n-1) and Tx (n-2) Touch actions can occur on all three transmission channels: Tx1, Tx2, and Tx6. Logically, the touch action must occur on a consecutively arranged transmission channel. Considering the adjacent positions of these channels, it can be determined that the actual touch occurred on an adjacent Tx1 channel. n Tx (n-1) and Tx (n-2) On these three passages, Figure 9 As shown, the possibility of non-adjacent transmission channels Tx1, Tx2 and Tx6 being touched can be ruled out, thereby achieving accurate positioning of the touch location.

[0099] The above example illustrates how to determine the touch position using the horizontal direction (X-axis direction), i.e. the arrangement direction of the transmitting channel Tx. This method is equally applicable to other directions (such as the arrangement direction of the receiving channel), such as the vertical direction (Y-axis direction), and even the tilted direction, and is within the protection scope of this patent, so it will not be elaborated here.

[0100] The detection circuit here performs self-capacitance or mutual capacitance detection by detecting the output signal of each receiving channel RX to determine whether the receiving channel has been touched. For example, the detection circuit may include a charge amplifier (CA) and a programmable gain amplifier (PGA). It may also include an analog antialiasing filter (AAF) with low-pass characteristics and an analog-to-digital conversion circuit (ADC), etc.

[0101] In one embodiment of this application, the first touch channels and the second touch channels are electrically isolated from each other. For example, different transmitting channels are separated from each other by a small gap, and different receiving channels are separated from each other by a larger gap.

[0102] In one embodiment of this application, the first touch sensing channel is located in the first sensing layer, the second touch sensing channel is located in the second sensing layer, the first sensing layer is superimposed on the second sensing layer, or the second sensing layer is superimposed on the first sensing layer.

[0103] The touch sensor in this application embodiment connects each of the adjacent first touch channels to a non-adjacent first touch channel and each of the adjacent second touch channels to a non-adjacent second touch channel. This allows the touch position to be located based on the adjacent and non-adjacent relationships between channels when a touch event occurs, without increasing the number of first and second touch channels. This reduces the design difficulty and manufacturing cost of the touch sensor.

[0104] According to an embodiment of this application, a touch panel is also provided, the touch panel including as follows: Figures 2 to 9 Touch sensor in the illustrated embodiment

[0105] According to an embodiment of this application, an electronic device is also provided, including the above-described touch panel.
