[0080] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numerals in different drawings denote the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present invention. Rather, they are merely examples of apparatuses and methods consistent with some aspects of the invention as detailed in the appended claims.

[0081] As technology advances, users have increasingly higher demands for the touch experience of electronic devices. For example, in application scenarios where touch operations are frequent, such as games, users may frequently engage in actions like rapid clicking or swiping, requiring extremely high sensitivity and accuracy in touch control.

[0082] In related technologies, in such application scenarios, electronic devices cannot accurately receive the coordinates corresponding to touch operations, resulting in inaccurate recognition or disconnection. Consequently, the electronic devices cannot accurately output the user's required instructions, which greatly affects the user experience.

[0083] Research has found that the main reasons for inaccurate recognition or contact loss issues in related technologies include:

[0084] First, after receiving a touch, the coordinates are often reported based on the capacitance change of a single mutual capacitance node. However, touch operations, especially swipe operations, may affect multiple mutual capacitance nodes. Therefore, the method of determining the original coordinates in related technologies is inaccurate.

[0085] Second, in game scenarios involving frequent operations, if the swipe operation is too fast, the electronic device may miss a frame of data and fail to report a certain frame of touch data, thus causing a touch interruption.

[0086] To address the technical problems in related technologies, this disclosure proposes a touch control method, comprising: determining a first region corresponding to a touch operation, the first region including multiple mutual capacitance nodes; determining the original coordinates of preset nodes in the first region, wherein the preset nodes are mutual capacitance nodes corresponding to the center position in the first region; and determining the control command corresponding to the touch operation based on the original coordinates of the preset nodes. Using the method of this disclosure, upon receiving a touch operation, the original coordinates corresponding to the center position are determined in the relevant region involved in the touch operation. The method of determining the original coordinates is more precise, thereby facilitating the accurate determination of the control command corresponding to the touch operation and improving the user experience.

[0087] In one exemplary embodiment, the touch control method of this embodiment is applied to an electronic device. The electronic device includes a display screen and a touch screen. The display screen may be, for example, an LCD display screen or an OLED display screen. The touch screen may be integrated onto a cover glass, which is disposed above the display screen. Alternatively, the touch screen may be integrated onto or within the display screen.

[0088] like Figure 1 As shown, the method in this embodiment may specifically include the following steps:

[0089] S110. Determine the first area corresponding to the touch operation. The first area includes multiple mutual capacitance nodes.

[0090] S120. Determine the original coordinates of the preset nodes in the first region.

[0091] S130. Determine the control command corresponding to the touch operation based on the original coordinates of the preset node.

[0092] Touch operations can be, for example, user commands during the use of an electronic device. The touchscreen receives the user's touch input and determines the touch location based on the input. The electronic device's processor receives the touch location information and issues corresponding control commands to control the display screen to show the corresponding content in conjunction with the touch operation.

[0093] A touchscreen, for example, is a mutual capacitance screen. It includes horizontal and vertical electrodes made of ITO (indium tin oxide), with mutual capacitance nodes formed at their intersections. At these nodes, the horizontal and vertical electrodes form the two poles of a capacitor. When a touch operation occurs, it affects the coupling between the two electrodes of the mutual capacitance node, thereby changing the capacitance value between them.

[0094] The lateral electrode can be a transmitting (TX) electrode, and the longitudinal electrode can be a receiving (RX) electrode. Each mutual capacitance node is connected to the sensing channel (the channel of the internal detection chip of the touch screen) via an ITO. The transmitting electrode can periodically send an excitation signal, the receiving electrode receives the signal, and the sensing channel determines the capacitance change at the corresponding mutual capacitance node by sensing the signal changes.

[0095] Therefore, the touchscreen can detect the change in capacitance at the node and determine the original coordinates to be reported to the processor based on the change in capacitance.

[0096] In step S110, the first area on the display screen of the electronic device in this step is the area affected by the touch operation, that is, the touch operation may affect multiple mutual capacitance nodes, causing the capacitance of multiple mutual capacitance nodes to change. The first area includes these multiple mutual capacitance nodes. For example, such as... Figure 8As shown, the first region includes 9 mutual capacitance nodes.

[0097] The processor can determine the first area based on the detection data from the touchscreen. Alternatively, the touchscreen can determine the first area and then report it to the processor.

[0098] In step S120, the preset node is the mutual capacitance node corresponding to the centroid position in the first region. For example, a two-dimensional centroid algorithm can be used to determine the centroid position of the first region in this step.

[0099] For example, such as Figure 8 As shown, the preset node is the node located at the center of the first region. The original coordinates of this preset node are determined as the coordinates corresponding to the touch operation. Understandably, in this example, the first region has a regular shape, and the capacitance change is greatest at the center of gravity, denoted as Diff. Here, capacitance change refers to the capacitance change between the two electrodes in the mutual capacitance node under the influence of a touch operation.

[0100] In step S130, the original coordinates of a preset node are used as the coordinates corresponding to the touch operation, and the touch screen reports these original coordinates. The processor can issue corresponding control commands based on these original coordinates to control the display screen to display in conjunction with the touch operation.

[0101] In one exemplary embodiment, such as Figure 2 As shown, step S120 in this embodiment may specifically include the following steps:

[0102] S121. Obtain the capacitance change of each mutual capacitance node in the first region.

[0103] S122. Obtain the node coordinates of the reference node.

[0104] S123. Determine the original coordinates of the preset node based on the capacitance change of each mutual capacitance node and the node coordinates of the reference node.

[0105] In step S121, when a touch operation occurs, the touchscreen can detect the capacitance change of each mutual capacitance node affected by the touch operation. The processor obtains the capacitance change of each mutual capacitance node in the first region.

[0106] like Figure 8 As shown, for example, the capacitance changes of the following mutual capacitance nodes involved in the first region are as follows: Diff 1, Diff 2, Diff 3, Diff 4, Diff, Diff 5, Diff 6, Diff 7 and Diff 8.

[0107] In step S122, each mutual capacitance node in the touchscreen has its corresponding node coordinates (horizontal and vertical coordinates). The processor can obtain the node coordinates of any mutual capacitance node as needed. In this step, the processor obtains the node coordinates of a reference node. For example, if the node coordinates of the reference node are (Tx8, Rx4), it indicates that the node is located at the intersection of the 8th horizontal electrode and the 4th vertical electrode. Figure 8 In the corresponding embodiment, the reference node coincides with the preset node.

[0108] In step S123, the original coordinates of the preset node are determined based on the values ​​of the capacitance changes in the first region involved in step S121 and the node coordinates involved in step S122.

[0109] like Figure 3 As shown, in this embodiment, step S123 may specifically include the following steps:

[0110] S1231. Determine the total capacitance change in the first region.

[0111] In this step, based on the capacitance change of each mutual capacitance node in the first region, the total capacitance change in the first region can be calculated. For example, as... Figure 8 In the example shown, the total capacitance change (ulSum_c) is:

[0112] ulSum_c=Diff 1+Diff 2+Diff 3+Diff 4+Diff+Diff 5+Diff 6+Diff 7+Diff8.

[0113] S1232. Determine the original coordinates of the preset nodes based on the capacitance change of each mutual capacitance node, the x-coordinate of the reference node, the node parameters of the two nodes adjacent to the reference node on the x-axis, and the total capacitance change.

[0114] In this step, node parameters may include, for example, the x-coordinates of adjacent nodes. For instance, the node parameters of the two nodes adjacent to the reference node on the x-axis include the x-coordinate of the left node and the x-coordinate of the right node of the reference node.

[0115] Combination Figure 8 As shown, the capacitance change corresponding to the reference node is the maximum value, Diff, and the node coordinates are (Tx8, Rx4). The x-coordinate of the node to the left of the reference node is Tx7, and the x-coordinate of the node to the right of the reference node is Tx9. The capacitance changes of the nodes in the first region are, in order, Diff 1, Diff 2, Diff 3, Diff 4, Diff, Diff 5, Diff 6, Diff 7, and Diff 8.

[0116] By combining the coordinates of the reference node and adjacent nodes, the initial x-coordinate of the preset node is obtained:

[0117] ulSum_tx=(Diff1+Diff4+Diff6)*Tx7+(Diff2+Diff+Diff7)*Tx8+(Diff3+Diff5+Diff8)*Tx9.

[0118] Therefore, the x-coordinate PosTX of the original coordinates of the preset node is: PosTX = ulSum_tx / ulSum_c.

[0119] S1233. Determine the original coordinates of the preset node based on the capacitance change of each mutual capacitance node, the ordinate of the reference node in the node coordinates, the node parameters of the two nodes adjacent to the reference node on the ordinate axis, and the total capacitance change.

[0120] In this step, node parameters may include, for example, the ordinates of adjacent nodes. For instance, the node parameters of the two nodes adjacent to the reference node on the ordinate axis include the ordinate of the node above the reference node and the ordinate of the node below the reference node.

[0121] Combination Figure 8 As shown, the capacitance change corresponding to the reference node is the maximum value, Diff, and the node coordinates are (Tx8, Rx4). The ordinate of the node above the reference node is Rx3, and the ordinate of the node below the reference node is Rx5. The capacitance changes of the nodes in the first region are, in order, Diff 1, Diff 2, Diff 3, Diff 4, Diff, Diff 5, Diff 6, Diff 7, and Diff 8.

[0122] By combining the coordinates of the reference node and adjacent nodes, the initial ordinate of the preset node is obtained:

[0123] ulSum_rx=(Diff1+Diff4+Diff6)*Rx3+(Diff2+Diff+Diff7)*Rx4+(Diff3+Diff5+Diff8)*Rx5.

[0124] Therefore, the original ordinate PosRX of the preset node is: PosRX = ulSum_rx / ulSum_c.

[0125] Understandably, the influence coefficients corresponding to (Diff1+Diff2+Diff3) or (Diff4+Diff+Diff5) or (Diff6+Diff7+Diff8) are considered to be 1, and therefore omitted in the above calculation formula.

[0126] Therefore, combining steps S1232 and S1233, in step S123, the original coordinates of the preset node are finally determined as (PosTX, PosRX) using the two-dimensional centroid algorithm.

[0127] Understandably, the above description uses... Figure 8 The corresponding example is illustrated, in which the preset node and the reference node coincide (both are located at the centroid of the first region), and the process of solving the original coordinates of the preset node is also the process of solving the original coordinates of the reference node. In other embodiments, when the first region is an irregularly shaped region, the preset node may not coincide with the reference node. In this case, the above calculation method is still used, and the original coordinates of the preset node are solved by using the relevant parameters of the reference node.

[0128] In this embodiment, the processor receives the original coordinates of a preset node reported by the touchscreen, or the processor determines the original coordinates of the preset node based on the relevant data reported by the touchscreen. During the determination of the original coordinates of the preset node, the influence of all mutual capacitance nodes within the first region is comprehensively considered, thereby more accurately determining the original coordinates to be reported. This allows the processor to issue more accurate control commands based on the highly accurate original coordinates, improving the touch experience in the application scenario.

[0129] In one exemplary embodiment, such as Figure 4 As shown, step S130 in this embodiment may specifically include the following steps:

[0130] S131. Determine the pixel coordinates corresponding to the original coordinates of the preset node.

[0131] S132. Determine the control command based on the pixel coordinates.

[0132] In step S131, the pixel coordinates correspond to the coordinates displayed on the screen. After obtaining the original coordinates of the preset node, the processor can determine the position corresponding to the touch operation and convert the original coordinates of the preset node into pixel coordinates for the display screen to recognize.

[0133] In step S132, after determining the pixel coordinates of the preset node, the processor can issue a control command containing the pixel coordinates to control the display screen to display content corresponding to the touch operation at the corresponding position (such as the position represented by the pixel coordinates).

[0134] In one exemplary embodiment, such as Figure 5 As shown, step S131 in this embodiment may specifically include the following steps:

[0135] S1311. Determine the conversion coefficient based on the area of ​​the preset node's original coordinates on the display screen.

[0136] S1312. Convert the original coordinates to pixel coordinates according to the conversion coefficient.

[0137] In step S1311, as follows Figure 9 As shown, the display screen area includes a central area, a secondary edge area, and an edge area. In the process of calculating the original coordinates of the preset node, as in step S120 above, the surrounding nodes of the preset node are referenced. However, for the secondary edge area of ​​the display screen, i.e. the edge area, there are no surrounding nodes for reference. Therefore, the coefficients for converting the original coordinates to pixel coordinates are different in the three areas.

[0138] The memory of an electronic device can store the correspondence between the display area and the conversion coefficient. The processor determines the corresponding conversion coefficient based on the area it is in.

[0139] In step S1312, the original coordinates of the preset node are converted into pixel coordinates according to the determined conversion coefficients.

[0140] In a specific example, such as Figure 9 As shown, for this display screen, the center point of the central area is A, the intersection of the central area and the secondary edge area is B, the intersection of the secondary edge area and the edge area is F, and the point D is located in the edge area.

[0141] Given that the original coordinates of point B are E0 and the pixel coordinates are P0; the original coordinates of point F are E1 and the pixel coordinates are P1; the original coordinates of point D are E2 and the pixel coordinates are P2; and the original coordinates of point A are C = ChNum * 256 / 2 and the pixel coordinates are Pc = P2 / 2, where ChNum represents the total number of sensing channels, and 256 represents the calculation precision of the sensing channels (2^35 * 2^6 * ... 8 (i.e., level 256).

[0142] It is understood that the coordinates mentioned above all include X-axis values ​​and Y-axis values. This embodiment is intended to illustrate the calculation method, and no specific distinction is made for ease of description.

[0143] In the first scenario:

[0144] When the original coordinates (PosTX, PosRX) of the preset node determined in step S120 are in the central region, that is, within the range of E0, the pixel coordinates corresponding to the preset node should also be within the range of P0. At this time, the pixel coordinates of the preset node are:

[0145] Px = |Pos–C|*K0+Cp;

[0146] Where K0 is the conversion coefficient corresponding to the central region, K0=|P0–Pc| / |E0–C|.

[0147] Cp represents the capacitance change at a preset node, such as in... Figure 8 In the example shown, Cp is the maximum capacitance change, Diff.

[0148] According to this formula, the x-coordinate of the preset node pixel coordinate is calculated using the x-coordinate PosTX of the original coordinates of the preset node, and the y-coordinate of the pixel coordinate is calculated using the y-coordinate PosRX of the original coordinates.

[0149] In the second scenario:

[0150] When the original coordinates (PosTX, PosRX) of the preset node determined in step S120 are in the secondary edge region, i.e., within the range of E0 to E1, the pixel coordinate range corresponding to the preset node should be within the range of P0 to P1. At this time, the pixel coordinates of the preset node are:

[0151] Px = |Pos–P0|*K1+P0;

[0152] Where K1 is the transformation coefficient corresponding to the sub-edge region, K1=|P1–P0| / |E1–E0|. The application of the formula is the same as in the previous scenario, and will not be repeated here.

[0153] In the third scenario:

[0154] When the original coordinates (PosTX, PosRX) of the preset node determined in step S120 are in the edge region, i.e., within the range of E1 to E2, the pixel coordinate range corresponding to the preset node should be within the range of P1 to P2. At this time, the pixel coordinates of the preset node are:

[0155] Px = |Po – P1| * K2 + P1;

[0156] Where K2 is the transformation coefficient corresponding to the edge region, K2=|P2–P1| / |E2–E1|. The application of the formula is the same as in the previous scenario, and will not be repeated here.

[0157] Based on the specific circumstances of the three scenarios described above, the processor can determine the pixel coordinates of preset nodes and then issue control commands. In this embodiment, the transformation coefficients of the coordinate transformation are adjusted regionally to improve the point reporting calculation speed and address the problem of inaccurate calculations caused by design defects in the display screen structure and electrode structure.

[0158] In one exemplary embodiment, such as Figure 6 As shown, the method in this embodiment further includes the following steps:

[0159] S210. In response to a touch operation being a swipe operation, determine the original coordinates of two adjacent preset nodes corresponding to two adjacent click operations in the swipe operation.

[0160] S220. Determine the control command corresponding to the sliding operation based on the original coordinates of two adjacent preset nodes.

[0161] In step S210, as described in the aforementioned embodiment, each determination of the original coordinates of a preset node is equivalent to receiving a click or quick click operation, allowing the electronic device to accurately determine the original coordinates and pixel coordinates of the preset node. When the touch operation is a swipe or draw, each touch action can be considered a click, and the overall swipe operation is considered to include multiple consecutive click actions.

[0162] For a swipe operation, determine the original coordinates corresponding to the click actions it contains. The original coordinates corresponding to each click action can be considered as one frame of data. Determine the data for multiple adjacent frames.

[0163] In step S220, control commands are determined based on the status of adjacent data frames.

[0164] In one example, in response to the fact that the original coordinates of the latter preset node among two adjacent predetermined preset nodes are 0, the original coordinates of the former preset node are used as the original coordinates of the latter preset node to determine the control command. An original coordinate of 0 for a preset node indicates that the touchscreen did not detect a click operation, therefore the capacitance change of the preset node corresponding to the click operation is 0, and the original coordinates of the corresponding preset node are 0.

[0165] In this example, during the swipe operation, if the user swipes too quickly, touch data might not be detected in a certain frame, resulting in an initial coordinate of 0. If the data in the previous frame is not 0, it can be used for patching, i.e., the previous frame's data is copied as the current frame's data. The processor determines the control instructions based on the initial coordinates of the two frames.

[0166] Therefore, in this example, it can be ensured that there will be no touch dropout during rapid swiping, improving the smoothness of touch operation and enhancing the user experience.

[0167] In another example, the sliding operation is terminated when the original coordinates of both preset nodes in two adjacent predetermined preset nodes are both 0.

[0168] In this example, if two consecutive frames of data are 0, it indicates that this is a normal end signal for the swipe operation (hand lifted), rather than a missed touch data detection. The swipe operation is then confirmed to be complete, and the processor issues corresponding instructions based on the collected swipe operation data.

[0169] In one exemplary embodiment, such as Figure 7 As shown, step S110 in this embodiment may specifically include the following steps:

[0170] S1101. Determine the second region and normalization coefficient corresponding to the touch operation.

[0171] S1102. Based on the normalization coefficient, the gain and the capacitance parameters of the mutual capacitance nodes in the second region.

[0172] S1103. Determine the first region in the second region based on the capacitor parameters after gain.

[0173] In step S1101, the second region may be, for example, a region corresponding to the touch operation that is not smaller than the first region. The normalization coefficient may be, for example, determined by the processor based on hardware characteristics and pre-stored in the processor. Hardware characteristics may include parameters such as the number, period, peak voltage, and sampling frequency of the excitation signal (waveform) sent by the transmit (TX) electrode, as well as the ADC sampling frequency in the detection chip. The processor can acquire this normalization coefficient at any time.

[0174] In step S1102, the normalization coefficient is used as a scaling factor to adjust the capacitance change of the node corresponding to the touch operation.

[0175] Before adjustment, the capacitance changes of each mutual capacitance node might differ only slightly (e.g., all on the order of tens), resulting in a potentially large and highly disruptive second region. However, after adjusting the scaling using normalization coefficients, the capacitance changes of each node in the second region after scaling (e.g., gain adjusted to the order of hundreds) become more distinct, making it easier to identify the main areas affected by touch operations.

[0176] It is understandable that the normalization coefficients corresponding to different mutual capacitance nodes may be the same or different.

[0177] In step S1103, based on the adjustment in step S1102, after adjustment using normalization coefficients, the main area affected by the touch operation in the second region can be determined, namely the first region. When determining the first region in the second region, it can be the node surrounding the node with the maximum capacitance change, where the capacitance change of the surrounding mutual capacitance nodes is also greater than the threshold, indicating that the first region is indeed the main area affected by the touch operation.

[0178] In this embodiment, by combining scaling adjustment, a more accurate first region can be determined, so that the capacitance change of each mutual capacitance node in the first region is within the optimal processing range, further improving the accuracy of the determination of the original coordinates and pixel coordinates.
