[0042] To make the objectives, technical solutions, and advantages of this disclosure clearer, the disclosure will be further described in detail below with reference to the accompanying drawings. The described embodiments should not be regarded as limitations on this disclosure. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this disclosure.

[0043] In the following description, reference is made to “some embodiments”, which describes a subset of all possible embodiments, but it will be understood that “some embodiments” may be the same subset or different subsets of all possible embodiments and may be combined with each other without conflict.

[0044] In the following description, the terms “first, second, third” are used merely to distinguish similar objects and do not represent a specific ordering of objects. It is understood that “first, second, third” may be interchanged in a specific order or sequence where permitted, so that the embodiments of this disclosure described herein can be implemented in an order other than that illustrated or described herein.

[0045] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this disclosure belongs. The terminology used herein is for the purpose of describing embodiments of this disclosure only and is not intended to be limiting of this disclosure.

[0046] The integrated circuit (IC) driver industry continues to drive the development of the smartphone industry. TDDI (Time-Division Divided) brings a unified system architecture. The original system architecture, because the display and touch chips were separate, could lead to display noise. TDDI, however, achieves unified control, resulting in better noise management. TDDI uses a "time-division scanning" method, dividing one frame of display time into two parts: one part for touch scanning and the other for display scanning, without interference, fundamentally reducing the risk of signal interference.

[0047] Touch reporting rate is essentially touch sensitivity; the higher the value, the more responsive the swipe. To improve responsiveness, a higher reporting rate is needed. Related technologies divide a frame of display time into multiple display phases and multiple non-display phases to achieve a higher reporting rate (non-display phases). However, multiple non-display phases consume some display time, shortening the duration of each display phase and thus reducing the display effect.

[0048] This disclosure provides a touch circuit. On one hand, by electrically connecting a first subunit to an odd number of touch sensing blocks in a first column and an even number of touch sensing blocks in a second column, the first subunit can simultaneously detect two columns of touch sensing blocks, increasing the touch sensing area and thus improving the accuracy of the touch position. On the other hand, based on the capacitance value of each touch sensing block, at least two touch reporting operations are completed, improving the touch reporting rate without reducing the display duration, thereby enhancing the display and touch effects. The touch circuit provided in this disclosure can be a component of an electronic device, which can be a laptop, tablet, desktop computer, set-top box, mobile device (e.g., mobile phone, portable music player, personal digital assistant, dedicated messaging device, portable gaming device), or a server. A server can be a standalone physical server, a server cluster or distributed system consisting of multiple physical servers, or a cloud server that provides basic cloud computing services such as cloud services, cloud databases, cloud computing, cloud functions, cloud storage, network services, cloud communication, middleware services, domain name services, security services, content delivery networks (CDN), and big data and artificial intelligence platforms.

[0049] The technical solutions in the embodiments of this disclosure will now be clearly and completely described with reference to the accompanying drawings.

[0050] Figure 1A This is a schematic diagram of the connection structure of a touch circuit provided in an embodiment of the present disclosure, as shown below. Figure 1A As shown, the touch circuit includes an array of touch units 10, a first detection unit 11, a second detection unit 12, and a control unit 13, wherein:

[0051] The touch unit 10 includes a first column of touch sensing blocks 101, a second column of touch sensing blocks 102 and a third column of touch sensing blocks 103 arranged at intervals, with the first column of touch sensing blocks 101 and the second column of touch sensing blocks 102 being adjacent to each other.

[0052] Here, the number of the first column of touch sensing blocks 101, the second column of touch sensing blocks 102, and the third column of touch sensing blocks 103 is at least one. Specifically, the number of the first column of touch sensing blocks 101 is the same as the number of the second column of touch sensing blocks, and the third column of touch sensing blocks 103 includes at least one column of touch sensing blocks. In implementation, those skilled in the art can determine the number and arrangement order of the first, second, and third columns of touch sensing blocks according to actual needs; this embodiment does not impose such limitations.

[0053] For example, the touch unit 10 includes 12 columns, divided into left and right halves of the screen, with each half occupying 6 columns. Taking the left half of the screen as an example, if the number of touch sensing blocks 101 in the first column, the number of touch sensing blocks 102 in the second column, and the number of touch sensing blocks 103 in the third column can all be 2, then the arrangement order can be as follows: "first column, second column, third column, first column, second column, third column", "third column, first column, second column, third column, first column, second column", or "third column, second column, first column, third column, second column, first column", etc. When the number of the first column of touch sensing blocks 101, the number of the second column of touch sensing blocks 102, and the number of the third column of touch sensing blocks 103 can be 1, 1, and 4 respectively, the arrangement order can be as follows: "first column, second column, third column, third column, third column, third column", "second column, first column, third column, third column, third column, third column", or "third column, first column, second column, third column, third column, third column, third column", etc.

[0054] For example, the touch unit 10 includes 18 columns, wherein the number of the first column of touch sensing blocks 101, the number of the second column of touch sensing blocks 102, and the number of the third column of touch sensing blocks 103 can be 4, 4, and 10, respectively.

[0055] In some implementations, each column of touch-sensitive blocks includes at least two touch-sensitive blocks.

[0056] The first detection unit 11 includes a first subunit 111 and a second subunit 112. The first subunit 111 is electrically connected to an odd number of touch sensors in the first column of touch sensors 101 and an even number of touch sensors in the second column of touch sensors 102. The second subunit 112 is electrically connected to an even number of touch sensors in the first column of touch sensors 101 and an odd number of touch sensors in the second column of touch sensors 102.

[0057] Here, the number of first detection units 11 is at least one. Both the first subunit 111 and the second subunit 112 include a multiplexer (MUX), which can output at least two signals in a time-division multiplexing manner. The signals output by the MUX may include, but are not limited to, detection signals and common voltage signals. The detection signal can be any suitable waveform, such as a square wave, sawtooth wave, or triangular wave. In implementation, those skilled in the art can determine the detection signal according to actual needs; this disclosure does not impose any limitations. The common voltage signal can be a preset DC voltage.

[0058] The second detection unit 12 is electrically connected to each of the touch sensing blocks in the third column of touch sensing blocks 103.

[0059] Here, the number of second detection units 12 is at least one. The second detection unit 12 includes a MUX.

[0060] In some implementations, the sum of the number of the first detection unit 11 and the number of the second detection unit 12 does not exceed the total number of columns of the touch unit 10.

[0061] For example, the touch unit 10 includes 18 columns, wherein the number of first detection units 11 can be at least one, and the number of second detection units 12 can be at least one. For example, the number of first detection units 11 is 2, and the number of second detection units 12 is 5. Or, for example, the number of first detection units 11 is 3, and the number of second detection units 12 is 3. In implementation, those skilled in the art can determine the number of first and second detection units according to actual needs, and the embodiments disclosed herein are not limited thereto.

[0062] Figure 1B This is a schematic diagram of the composition structure of a touch circuit provided in an embodiment of the present disclosure, as shown below. Figure 1B As shown, the touch circuit includes a 32-row x 18-column touch unit 10, three first detection units 11, three second detection units 12, and a control unit 13. Wherein:

[0063] The odd number of touch sensing blocks in the first column of the first quarter touch sensing blocks 101 are electrically connected to the first sub-unit 111 in the first detection unit 11, and the even number of touch sensing blocks in the first column of the first quarter touch sensing blocks 101 are electrically connected to the second sub-unit 112 in the first detection unit 11.

[0064] The odd number of touch sensing blocks in the first / fourth second column of touch sensing blocks 102 are electrically connected to the second sub-unit 112 in the first first detection unit 11, and the even number of touch sensing blocks in the first / fourth second column of touch sensing blocks 102 are electrically connected to the first sub-unit 111 in the first first detection unit 11.

[0065] The third column of the first / fourth touch sensor block 103 is electrically connected to the first second detection unit 12.

[0066] In some embodiments, the third column of touch sensing blocks 103 includes adjacent first sub-column touch sensing blocks 1031 and second sub-column touch sensing blocks 1032. The second detection unit 12 includes a third sub-unit 121 and a fourth sub-unit 122. The third sub-unit 121 is electrically connected to an odd number of touch sensing blocks in the first sub-column touch sensing blocks 1031 and an even number of touch sensing blocks in the second sub-column touch sensing blocks 1032. The fourth sub-unit 122 is electrically connected to an even number of touch sensing blocks in the first sub-column touch sensing blocks 1031 and an odd number of touch sensing blocks in the second sub-column touch sensing blocks 1032.

[0067] Specifically, the first sub-column touch sensor block 1031 is the same as the first column touch sensor block 101, and the second sub-column touch sensor block 1032 is the same as the second column touch sensor block 102. The third sub-unit 121 is the same as the first sub-unit 111, and the fourth sub-unit 122 is the same as the second sub-unit 112.

[0068] Figure 1C This is a schematic diagram of the composition structure of a touch circuit provided in an embodiment of the present disclosure, as shown below. Figure 1C As shown, the touch circuit includes a 32-row x 16-column touch unit 10, two first detection units 11, two second detection units 12, and a control unit 13. Wherein:

[0069] The odd number of touch sensing blocks in the first column of the first third of the first touch sensing blocks 101 are electrically connected to the first sub-unit 111 in the first detection unit 11, and the even number of touch sensing blocks in the first column of the first third of the first touch sensing blocks 101 are electrically connected to the second sub-unit 112 in the first detection unit 11.

[0070] The odd number of touch sensing blocks in the first / third second column of touch sensing blocks 102 are electrically connected to the second sub-unit 112 in the first first detection unit 11, and the even number of touch sensing blocks in the first / third second column of touch sensing blocks 102 are electrically connected to the first sub-unit 111 in the first first detection unit 11.

[0071] The odd number of touch sensing blocks in the first 1 / 3 first sub-column touch sensing block 101 are electrically connected to the third sub-unit 121 in the first second detection unit 12, and the even number of touch sensing blocks in the first 1 / 3 first sub-column touch sensing block 101 are electrically connected to the fourth sub-unit 122 in the first second detection unit 12.

[0072] The odd number of touch sensing blocks in the first / third second sub-column touch sensing block 102 are electrically connected to the fourth sub-unit 122 in the first second detection unit 12, and the even number of touch sensing blocks in the first / third second sub-column touch sensing block 102 are electrically connected to the third sub-unit 121 in the first second detection unit 12.

[0073] The control unit 13 is used to control the target detection unit to output a detection signal, determine the capacitance value of the corresponding electrically connected touch sensing block, and complete at least two touch reporting based on each capacitance value. The target detection unit includes one of the following: a first subunit, a second subunit, and a second detection unit.

[0074] Here, the control unit 13 can be any suitable module capable of implementing control functions. For example, a CPU (Central Processing Unit). In implementation, those skilled in the art can determine the control unit independently according to actual needs, and the embodiments disclosed herein are not limited thereto.

[0075] At least two touch notifications can include at least one first touch notification and at least one second touch notification. In practice, the first touch notification is performed in the same way as the second touch notification.

[0076] The first touch detection report is obtained based on each detected value and each predicted value. Each detected value represents the actual detected capacitance value. In some embodiments, the detected value can be the capacitance value of the touch sensing block electrically connected to the first target detection unit, detected when the first target detection unit outputs a detection signal, with each capacitance value used as a separate detected value. The first target detection unit may include, but is not limited to, a first sub-unit, a third sub-unit, a fourth sub-unit, etc.

[0077] Each predicted value represents a predicted capacitance value. In some embodiments, the capacitance value of each touch sensing block electrically connected to the second target detection unit is predicted based on the detection value of each touch sensing block electrically connected to the first target detection unit, and each capacitance value is used as a predicted value. The second target detection unit may include, but is not limited to, a second sub-unit, a fourth sub-unit, etc.

[0078] The second touch detection is based on each first detection value and each second detection value. Each first detection value is the capacitance value actually detected by the first target detection unit, and each second detection value is the capacitance value actually detected by the second target detection unit. That is, when the second target detection unit outputs a detection signal, the capacitance value of the touch sensing block electrically connected to the second target detection unit is detected, and each capacitance value is used as each second detection value.

[0079] In some implementations, for each touch sensor block electrically connected to the second target detection unit, a preset first algorithm is used to determine the predicted value of the touch sensor block based on the first detection values ​​of at least one adjacent touch sensor block. The first algorithm can be any suitable estimation method, such as centroid, root mean square error, or cross mean. In implementation, those skilled in the art can choose the first algorithm according to actual needs; this disclosure does not limit the choice. The centroid refers to the mean of the coordinates of points adjacent to the object. The cross mean refers to the mean of the coordinates of points adjacent to the object in the cross direction.

[0080] Figure 1D This is a schematic diagram illustrating the composition of a touch unit provided in an embodiment of this disclosure. Figure 1D As shown, the touch unit 10 includes 4 rows and 3 columns, with a total of twelve touch sensing blocks, namely: 1 to 12. Assuming that the capacitance values ​​(Rawi) of the 1st, 3rd, 5th, 6th, 7th, 9th, 11th, and 12th touch sensing blocks are known, the capacitance value Raw2 of the 2nd touch sensing block can be obtained based on the capacitance values ​​Raw1 of the 1st touch sensing block, Raw3 of the 3rd touch sensing block, and Raw5 of the 5th touch sensing block. For example, the average of Raw1, Raw3, and Raw5 can be used as Raw2, or the mean square error of Raw1, Raw3, and Raw5 can be used as Raw2.

[0081] Figure 1E This is a schematic diagram illustrating the composition of a touch unit provided in an embodiment of this disclosure. Figure 1EAs shown, the touch unit 10 includes 4 rows and 4 columns, totaling sixteen touch sensing blocks, namely: 1 to 16. Assuming the capacitance values ​​(Rawi) of the 1st, 3rd, 6th, 8th, 9th, 11th, 14th, and 16th touch sensing blocks are known, the capacitance value (Raw2) of the 2nd touch sensing block can be obtained based on the capacitance values ​​(Raw1, Raw3, and Raw6) of the 1st, 3rd, and 6th touch sensing blocks. For example, the average of Raw1, Raw3, and Raw6 can be used as Raw2, or the root mean square error of Raw1, Raw3, and Raw6 can be used as Raw2. The capacitance value Raw12 of the 12th touch sensor block can be obtained based on the capacitance values ​​Raw8 of the 8th touch sensor block, Raw11 of the 11th touch sensor block, and Raw16 of the 16th touch sensor block. For example, the average of Raw8, Raw11, and Raw16 can be used as Raw12, or the root mean square error of Raw8, Raw11, and Raw16 can be used as Raw12.

[0082] In some implementations, touch position information can be obtained based on the capacitance value of each touch sensing block, and the touch position information can be reported to complete the first touch reporting.

[0083] Here, the capacitance value may include, but is not limited to, the first detection value, the second detection value, the predicted value, etc.

[0084] The methods for obtaining touch position information may include, but are not limited to, the sum / difference / product / mean / variance / mean square error of the capacitance values ​​of the target touch sensing blocks, or the weighted sum / difference / product / mean / variance / mean square error of the capacitance values ​​of the target touch sensing blocks. The target touch sensing blocks may include, but are not limited to, each touch sensing block or a subset of touch sensing blocks. A subset of touch sensing blocks may refer to a set of touch sensing blocks and surrounding touch sensing blocks whose capacitance values ​​meet preset conditions. These preset conditions may include, but are not limited to, capacitance value changes or capacitance values ​​exceeding a threshold. In implementation, those skilled in the art can independently set the preset conditions and determine the method for obtaining touch position information according to actual needs; this disclosure does not limit such methods.

[0085] In some implementations, the touch position information (x) can be calculated using the following formula (1-1). c ,y c ):

[0086]

[0087] Where, m ix represents the capacitance value of the i-th target touch sensor block. i y represents the row value of the i-th target touch sensor block. i Let M represent the column of the i-th target touch sensor block, M represent the capacitance value of all target touch sensor blocks, i∈{1,2,……,k}, and k represent the total number of target touch sensor blocks.

[0088] For example, for a 32*18 touch unit with a total of 576 touch sensing blocks, if a change in the capacitance value of the third touch sensing block is detected, the target touch sensing blocks can include the second, third, fourth, and 35th touch sensing blocks. The touch position information (x) can be obtained using the formula (1-1) above. c ,y c ).

[0089] In this embodiment, on the one hand, by electrically connecting the first subunit to an odd number of touch sensing blocks in the first column and an even number of touch sensing blocks in the second column, the first subunit can simultaneously detect two columns of touch sensing blocks, increasing the touch sensing area and thus improving the accuracy of the touch position. On the other hand, based on the capacitance value of each touch sensing block, at least two touch reporting operations are completed, thereby increasing the touch reporting rate without reducing the duration of the display phase, thus improving the display and touch effects.

[0090] In some embodiments, the touch circuit further includes at least one signal acquisition unit, each of which is electrically connected to a row of touch sensing blocks; the control unit 13 is further configured to: control the target detection unit to output the detection signal, acquire the feedback signal of each of the signal acquisition units, and determine the capacitance value of the touch sensing block electrically connected to the target detection unit based on each feedback signal.

[0091] Here, the signal acquisition unit can be any suitable unit capable of outputting a feedback signal. For example, an AFE (Analog Front-end).

[0092] In some implementations, the number of signal acquisition units is an integer multiple of the total number of rows of the touch unit 10. For example, if the touch unit 10 includes 32 rows, then the number of signal acquisition units can be 64.

[0093] Figure 1F This is a schematic diagram of the composition structure of a touch circuit provided in an embodiment of the present disclosure, as shown below. Figure 1FAs shown, the touch circuit includes a touch unit 10, a first detection unit 11, a second detection unit 12, and a signal acquisition unit (AFE) 14. The touch unit 10 includes a first column of touch sensing blocks 101, a second column of touch sensing blocks 102, and a third column of touch sensing blocks 103. The first detection unit 11 includes a first subunit 111 and a second subunit 112. The first subunit 111 is electrically connected to an odd number of touch sensing blocks in the first column of touch sensing blocks 101 and an even number of touch sensing blocks in the second column of touch sensing blocks 102. The second subunit 112 is electrically connected to an even number of touch sensing blocks in the first column of touch sensing blocks 101 and an odd number of touch sensing blocks in the second column of touch sensing blocks 102. The second detection unit 12 is electrically connected to each touch sensing block in the third column of touch sensing blocks 103. Each signal acquisition unit (AFE) 14 is electrically connected to a row of touch sensing blocks.

[0094] In this embodiment, on the one hand, the number of signal acquisition units is reduced by using the multiplexer of the target detection unit, thereby reducing the size of the integrated circuit; on the other hand, by using the detection signal output by the target detection unit to control each signal acquisition unit to acquire data from the electrically connected touch sensing block, the touch detection efficiency can be improved.

[0095] In some embodiments, the touch circuit further includes at least one control switch; for each control switch, a first terminal of the control switch is electrically connected to a signal acquisition unit, and a second terminal of the control switch is electrically connected to a row of touch sensing blocks; the control unit is further configured to control each of the control switches to close, so that the corresponding signal acquisition unit is connected to the row of touch sensing blocks; and / or to control each of the control switches to open, so that the corresponding signal acquisition unit is disconnected from the row of touch sensing blocks.

[0096] In this embodiment of the disclosure, a control switch is used to control the connection and disconnection between the signal acquisition unit and the touch sensing block, which enables the signal acquisition unit to acquire the capacitance value of the touch sensing block, thereby improving the acquisition efficiency.

[0097] In some implementations, the touch circuit further includes an analog-to-digital converter (ADC). This ADC may include multiple input ports, each electrically connected to a signal acquisition unit. The ADC converts the feedback signal output by each signal acquisition unit into a digital signal, facilitating detection and identification by the control unit.

[0098] Here, the analog-to-digital conversion unit can be any suitable circuit capable of converting analog signals into digital signals. For example, an analog-to-digital converter (ADC). In implementation, those skilled in the art can determine the analog-to-digital conversion unit according to actual needs; this disclosure does not impose any limitations.

[0100] Step S21: Determine the capacitance value of each of the touch sensing blocks.

[0101] Here, the capacitance value may include, but is not limited to, the detected value and the predicted value. The detected value represents the actual measured capacitance value, and the predicted value represents the predicted capacitance value. For example, for each touch sensor block electrically connected to the first sub-unit, the capacitance value of that touch sensor block can be measured when the first sub-unit outputs a detection signal. As another example, for each touch sensor block electrically connected to the second sub-unit, the capacitance value of that touch sensor block can be predicted based on the capacitance values ​​of at least one adjacent touch sensor block.

[0102] Step S22: Based on each of the capacitance values, complete at least two touch reporting operations.

[0103] Here, at least two touch notifications can include at least one first touch notification and at least one second touch notification. In practice, the first touch notification is performed in the same way as the second touch notification.

[0104] The first touch detection report is obtained based on each detected value and each predicted value. Each detected value represents the actual detected capacitance value. In some embodiments, the detected value can be the capacitance value of the touch sensing block electrically connected to the first target detection unit when the first target detection unit outputs a detection signal, and each capacitance value is used as a detected value. The first target detection unit may include, but is not limited to, a first sub-unit, a third sub-unit, a fourth sub-unit, etc. Each predicted value represents the predicted capacitance value. In some embodiments, based on the detected values ​​of each touch sensing block electrically connected to the first target detection unit, the capacitance value of each touch sensing block electrically connected to the second target detection unit is predicted, and each capacitance value is used as a predicted value. The second target detection unit may include, but is not limited to, a second sub-unit, a fourth sub-unit, etc.

[0105] The second touch detection is based on each first detection value and each second detection value. Each first detection value is the capacitance value actually detected by the first target detection unit, and each second detection value is the capacitance value actually detected by the second target detection unit. That is, when the second target detection unit outputs a detection signal, the capacitance value of the touch sensing block electrically connected to the second target detection unit is detected, and each capacitance value is used as each second detection value.

[0106] In some implementations, when the number of first touch reports is at least two, the first first touch report can be obtained based on each first detection value and each predicted value. The Nth first touch report can be obtained based on each first detection value, a partial second detection value, and each predicted value, where N is an integer greater than 1. The partial second detection value can refer to: when the target second subunit outputs a detection signal, detecting the capacitance value of the touch sensing block electrically connected to the target second subunit, and using each capacitance value as a partial second detection value. The target second subunit is the first A second subunits, where A is a positive integer less than B, and B is the total number of second subunits.

[0109] MUX3 and MUX8 jointly control the touch sensor blocks in columns 4-5 or 13-14. Specifically, MUX3 controls the odd number of touch sensor blocks in columns 4 / 13 and the even number of touch sensor blocks in columns 5 / 14, while MUX8 controls the even number of touch sensor blocks in columns 4 / 13 and the odd number of touch sensor blocks in columns 5 / 14.

[0110] MUX5 and MUX9 jointly control the touch sensor blocks in columns 7-8 or 16-17. Specifically, MUX5 controls the odd number of touch sensor blocks in columns 7 / 16 and the even number of touch sensor blocks in columns 8 / 17, while MUX9 controls the even number of touch sensor blocks in columns 7 / 16 and the odd number of touch sensor blocks in columns 8 / 17.

[0111] MUX2 controls the touch sensor blocks in columns 3 and 12, MUX4 controls the touch sensor blocks in columns 6 and 15, and MUX6 controls the touch sensor blocks in columns 9 and 18.

[0112] In this embodiment, the capacitance value of each touch sensing block is determined; based on each capacitance value, at least two touch reporting operations are performed. Thus, by performing at least two touch reporting operations based on the capacitance value of each touch sensing block, the touch reporting rate is increased without reducing the duration of the display phase, thereby improving the display and touch performance.

[0113] In some embodiments, the capacitance value of each touch sensing block electrically connected to the first subunit and the second detection unit includes a first detected value, and the capacitance value of each touch sensing block electrically connected to the second subunit includes a predicted value and a second detected value; step S22 includes steps S221 to S223, wherein:

For example, the average of Raw5, Raw7, Raw9, and Raw11 can be used as Raw8, or the mean square error of Raw5, Raw7, Raw9, and Raw11 can be used as Raw8.

[0117] In some embodiments, step S221 includes step S231, wherein:

[0121] Here, touch position information can be obtained based on the capacitance value of each touch sensor block, and this touch position information is reported to complete the first touch reporting. The capacitance value can include, but is not limited to, a first detection value, a predicted value, and a fifth detection value. The fifth detection value is the capacitance value of each electrically connected touch sensor block detected when the first A second sub-units output detection signals. A is a positive integer less than B, and B is the total number of second sub-units.

[0122] Step S223: Based on each of the first detection value and each of the second detection values, complete the second touch reporting.

[0123] Here, the second touch reporting method is the same as the first touch reporting method. For implementation, please refer to the specific implementation method of step S222 described above.

[0124] In this embodiment, each predicted value is determined based on each first detection value; a first touch reporting is completed based on each first detection value and each predicted value; and a second touch reporting is completed based on each first detection value and each second detection value. In this way, by obtaining each predicted value from each first detection value, virtual detection of a portion of the touch sensing blocks is achieved, and touch reporting is performed, enabling at least two touch reportings to be completed within the same touch time, thereby improving the touch reporting rate.

[0125] In some embodiments, step S222 includes steps S241 to S242, wherein:

[0126] Step S241: Using a preset second algorithm, determine the touch position information based on the position information of each touch sensing block and the corresponding first capacitance value.

The method for determining the touch position information may include, but is not limited to, the sum / difference / product / mean / variance / mean square error of the capacitance values ​​of the target touch sensing blocks, or the weighted sum / difference / product / mean / variance / mean square error of the capacitance values ​​of the target touch sensing blocks. The target touch sensing blocks may include, but are not limited to, each touch sensing block or a subset of touch sensing blocks. A subset of touch sensing blocks may refer to a touch sensing block and its surrounding touch sensing blocks being considered as a subset of touch sensing blocks when the capacitance value of a certain touch sensing block meets a preset condition. The preset condition may include, but is not limited to, capacitance value changes or capacitance values ​​exceeding a threshold. In implementation, those skilled in the art can independently set the preset conditions and determine the method for obtaining the touch position information according to actual needs; this disclosure does not limit such implementation.

[0129] In some embodiments, step S241 includes step S251, wherein:

[0130] Step S251: For each touch sensor block, if the first capacitance value of the touch sensor block meets the preset conditions, determine the touch position information based on the position information of the target touch sensor block.

In implementation, those skilled in the art can independently set the method for determining touch position information according to actual needs; this disclosure does not impose any limitations.

[0134] In some implementations, the touch position information can be obtained using the above formula (1-1).

[0135] In some implementations, determining the touch position information based on the position information of the target touch sensing block in step S251 includes steps S261 to S263, wherein:

[0136] Step S261: Determine the second capacitance value based on the position information of the target touch sensing block and the corresponding first capacitance value.

[0137] Here, the method for determining the second capacitance value may include, but is not limited to, the sum / sum of squares of the product of each location information and its corresponding first capacitance value, or the sum / sum of squares of the product of each location information and its corresponding first capacitance value after weighting them separately.

[0142] Step S242: Report the touch location information to complete the first touch reporting.

[0143] In this embodiment, for each touch sensing block, if the first capacitance value of the touch sensing block meets a preset condition, the touch position information is determined based on the position information of the target touch sensing block; the touch position information is then reported to complete the first touch reporting. In this way, determining the touch position information based on the position information of the target touch sensing block not only reduces the computational load of the touch position information, but also increases the effective touch area by using the position information of multiple target touch sensing blocks, thereby improving the accuracy of the touch position information.

[0144] In some embodiments, the second detection unit includes a third subunit and a fourth subunit, the capacitance value of each touch sensing block electrically connected to the first subunit and the third subunit includes a third detected value, and the capacitance value of each touch sensing block electrically connected to the second subunit and the fourth subunit includes a first predicted value and a fourth detected value; step S22 includes steps S271 to S273, wherein:

[0145] Step S271: Determine each of the first predicted values ​​based on each of the third detection values.

[0146] Here, the third detection value is the same as the first detection value. The method for determining the first predicted value in the above steps is similar to the method for determining the predicted value in step S221. In implementation, the specific implementation method of step S221 can be referred to.

[0147] Step S272: Based on each of the third detection values ​​and each of the first prediction values, complete the first touch reporting.

[0148] Here, the method of completing the first touch reporting in the above steps is similar to the method of completing the first touch reporting in step S222. When implementing it, you can refer to the specific implementation method of the aforementioned step S222.

[0149] Step S273: Based on each of the third detection values ​​and each of the fourth detection values, complete the second touch reporting.

[0150] Here, the fourth detection value is the same as the second detection value. The method for completing the second touch reporting in the above steps is similar to the method for completing the second touch reporting in step S223.

[0151] In this embodiment, each first predicted value is determined based on each of the third detection values; a first touch reporting is completed based on each of the third detection values ​​and each of the first predicted values; and a second touch reporting is completed based on each of the third detection values ​​and each of the fourth detection values. Thus, by obtaining each first predicted value from each third detection value, virtual detection of a portion of the touch sensing blocks is achieved, and touch reporting is performed, enabling at least two touch reportings to be completed within the same touch time, thereby improving the touch reporting rate.

[0152] The following describes the application of the touch circuit provided in this embodiment in a real-world scenario, using an HD (High Definition) TDDI IC touch circuit as an example. This touch circuit includes 32*18 touch units, i.e., 576 touch sensing blocks, and 9 target detection units, i.e., MUX1 to MUX9. The touch units are divided into left and right halves of the screen; the left half is used as an example.

[0153] In related technologies, each target detection unit controls a column of touch sensing blocks. Within one display frame, all nine MUXs are detected to complete one touch reporting. This requires nine non-display stages, meaning the display needs to pause nine times. If two touch reportings are required, 18 non-display stages are needed, meaning the display needs to pause 18 times. And so on. To achieve a high reporting rate, the more non-display stages required, the shorter the duration of each display stage becomes. This can easily lead to insufficient charging of the panel pixel capacitors, resulting in poor panel display quality.

[0154] Figure 3A This is a schematic diagram illustrating the connection relationship between a touch unit and a target detection unit in a related art, as provided in an embodiment of this disclosure. Figure 3A As shown, MUX1 to MUX9 control columns 1 to 9 respectively. By sequentially opening MUX1 to MUX9, the capacitance values ​​of all touch sensing blocks are detected, and a touch reporting is completed based on each capacitance value.

[0155] This disclosure provides a scheme for cross-controlling touch sensing blocks within the same MUX. On one hand, a first subunit is electrically connected to an odd number of touch sensing blocks in a first column and an even number of touch sensing blocks in a second column. A second subunit is also electrically connected to an even number of touch sensing blocks in the first column and an odd number of touch sensing blocks in the second column. This allows the first subunit to simultaneously detect two columns of touch sensing blocks, increasing the touch sensing area and improving the accuracy of the touch position. On the other hand, based on each first detection value and each predicted value, at least one first touch reporting is performed; and based on each first detection value and each second detection value, a second touch reporting is performed. This increases the touch reporting rate without reducing the display phase duration, thereby improving the display and touch performance.

By sequentially opening MUX1-MUX6, the capacitance value 311 of each touch sensor block electrically connected to MUX1-MUX6 is detected; based on each capacitance value, the capacitance value 312 of the touch sensor blocks electrically connected to MUX7-MUX9 is predicted; based on each capacitance value 311 and each capacitance value 312, the first touch reporting is completed; by sequentially opening MUX7-MUX9, the capacitance value 313 of the touch sensor blocks electrically connected to MUX7-MUX9 is detected; based on each capacitance value 311 and each capacitance value 313, the second touch reporting is completed.

The first algorithm is used to predict the capacitance value 312 of the touch sensing blocks electrically connected to MUX7 to MUX9. Based on each capacitance value 311 and each capacitance value 312, the first touch position information is obtained.

[0158] Figure 3D This is a schematic diagram illustrating the control results of a touch unit and a target detection unit provided in an embodiment of this disclosure, as shown below. Figure 3D As shown, for the capacitance values ​​of the touch sensing blocks electrically connected to MUX1 to MUX6, the capacitance value 311 obtained in the previous detection is used to sequentially open MUX7 to MUX9, and the capacitance value 313 of the touch sensing blocks electrically connected to MUX7 to MUX9 is detected. Based on each capacitance value 311 and each capacitance value 313, the second touch position information is obtained.

[0159] Figure 3E This is a schematic diagram of a touch reporting point provided in an embodiment of the present disclosure, such as... Figure 3E As shown, before reporting the touch position to the terminal, the IC first sends an interrupt (INT) signal to the terminal. Using scheme 1 in the related technology, after completing 9 MUX scans, an interrupt signal INT is sent to the terminal, and the touch position information is reported to the terminal. Using scheme 2 provided in this embodiment, after completing 6 MUX scans, an interrupt signal INT is sent to the terminal, and the first touch position information is reported to the terminal; after completing 9 MUX scans, an interrupt signal INT is sent to the terminal, and the second touch position information is reported to the terminal.

[0160] Figure 3F This is a schematic diagram illustrating the implementation process of a touch reporting method provided in an embodiment of this disclosure, as shown below. Figure 3F The method includes steps S31 to S35, wherein:

[0161] Step S31: Open MUX1 to MUX6 in sequence, detect the capacitance value of the touch sensing blocks that are electrically connected to MUX1 to MUX6, and use each capacitance value as the first detection value.

[0162] Step S32: Using the cross mean calculation method (corresponding to the first algorithm above), predict the capacitance value of the touch sensing blocks electrically connected to MUX7 to MUX9, and use each capacitance value as a predicted value.

[0163] Step S33: Based on each first detection value and each first prediction value, determine the first touch position information, report the first touch position information, and complete the first touch reporting.

[0164] Step S34: Open MUX7 to MUX9 in sequence, detect the capacitance value of the touch sensing block electrically connected to MUX7 to MUX9, and use each capacitance value as each second detection value.

[0165] Step S35: Based on each first detection value and each second detection value, determine the second touch position information, report the second touch position information, and complete the second touch reporting.

[0166] In this embodiment, on the one hand, by electrically connecting the first subunit to an odd number of touch sensing blocks in the first column and an even number of touch sensing blocks in the second column, the first subunit can simultaneously detect two columns of touch sensing blocks, increasing the touch sensing area and thus improving the accuracy of the touch position. On the other hand, based on the capacitance value of each touch sensing block, at least two touch reporting operations are completed, thereby increasing the touch reporting rate without reducing the duration of the display phase, thus improving the display and touch effects.
