[0063] To address the technical problems described in the background section, in one embodiment, such as Figure 1 As shown, this application provides a display touch integrated chip 110, configured with multiple input terminals 113. The input terminals 113 are used to connect to a touch screen to receive sensing detection signals from the touch screen. The combined sensing electrode includes multiple independent sensing electrodes 101. The display touch integrated chip 110 includes: multiple touch detection circuits 111, which are connected to the input terminals 113. The touch detection circuits 111 are used to receive the sensing signals input from the input terminals 113 to obtain sensing detection data. Each touch detection circuit obtains the sensing detection data of one combined sensing electrode at a time. A point calculation logic module 114 is connected to the multiple touch detection circuits 111 and is used to calculate sensing analysis data based on the sensing detection data to determine the touch position of the touch screen. The sensing analysis data is the sensing data of one of the independent sensing electrodes 101 in the combined sensing electrode.

[0064] In this embodiment, a touch detection circuit acquires the sensing detection data of a combined sensing electrode at a time. A combined sensing electrode includes multiple independent sensing electrodes. The point calculation logic module calculates the sensing detection data and can obtain the sensing analysis data of multiple independent sensing electrodes at a time to determine the touch position. This can greatly reduce the touch detection circuit required to complete the touch position determination, thereby reducing the chip area.

[0065] In one embodiment, when the point calculation logic module determines the touch position of the touch display screen based on the sensing analysis data, the point calculation logic module is specifically used for:

[0066] The touch coordinates of the touch display screen are calculated based on the sensor analysis data;

[0067] The touch position of the touch display screen is determined based on the touch coordinates of the touch display screen.

[0068] In this embodiment, the point calculation logic module can calculate based on the sensing analysis data of each independent module to obtain accurate touch points, determine the touch coordinates of the touch points, and then determine the touch position of the touch display screen. It can calculate based on the sensing detection data of the combined sensing electrode containing multiple independent sensing electrodes obtained by the touch detection circuit to obtain the sensing analysis data of each independent sensing electrode, and then obtain the touch coordinates, which improves the detection efficiency and reduces the number of touch detection lines while ensuring the accuracy of the detected touch position.

[0069] In one embodiment, the display touch integrated chip 110 further includes, for example, Figure 2 The switch module 112 shown includes a plurality of first terminals 201 and a second terminal 202. The plurality of first terminals 201 of the switch module 112 are respectively connected to a plurality of input terminals 113 in a one-to-one correspondence. The second terminal 202 of the switch module 112 is connected to a corresponding touch detection circuit 111. The switch module 112 is used to select and conduct at least one signal transmission path between the first terminal 201 and the second terminal 202.

[0070] Refer again Figure 2 The switch module 112 includes a plurality of switches 203, each switch 203 having two ends. One end of each of the plurality of switches is connected to a plurality of first ends 201 in a one-to-one correspondence, and the other end of each of the plurality of switches is connected to a second end 202.

[0071] In this embodiment, the switch module 112 includes multiple switches to control whether the connection between the touch detection circuit 111 and the combined sensing electrodes is open, which can flexibly control the reception of sensing detection data of a certain combined sensing electrode and ensure that complete and accurate sensing detection data is received.

[0072] In one embodiment, this application also provides a touch module, including the display touch integrated chip and touch display screen as described in any of the above embodiments, such as... Figure 3 As shown, the touch display screen includes multiple combined sensing electrodes 100. The display touch integrated chip 110 includes multiple input terminals 113, and the touch detection circuit 111 is used to determine the touch position of the touch display screen based on the sensing detection data input from the input terminals 113.

[0073] The multiple combined sensing electrodes 100 are arranged in an array, and two adjacent combined sensing electrodes 100 in the first direction are staggered in the second direction. The first direction is perpendicular to the second direction. Each combined sensing electrode 100 includes multiple independent sensing electrodes 101 arranged sequentially in the first direction, and multiple independent sensing electrodes 101 in the same combined sensing electrode 100 are connected to the same touch detection circuit 111.

[0074] In this embodiment, by setting multiple combined sensing electrodes arranged in an array, and connecting multiple independent sensing electrodes 101 in the same combined sensing electrode to the same touch detection circuit 111 of the display touch integrated chip, the number of touch detection circuits 111 required by the display touch integrated chip can be significantly reduced, thereby reducing the chip area.

[0075] In one embodiment, such as Figure 4 As shown, each of the combined sensing electrodes 100 includes two independent sensing electrodes 101. In this embodiment, one combined sensing electrode 100 includes two independent sensing electrodes 101, which facilitates the detection of the signal output by the combined sensing electrode 100 by the display touch integrated chip 110.

[0076] In one embodiment, a plurality of the individual sensing electrodes 101 in the same combined sensing electrode 100 are connected together, and one of the individual sensing electrodes 101 in the same combined sensing electrode 100 is connected to the same touch detection circuit 111.

[0077] In this embodiment, as Figure 5 As shown, taking a combined sensing electrode 100 comprising two independent sensing electrodes 101 as an example, where a dashed box represents a combined sensing electrode 100, the two independent sensing electrodes 101 in the same combined sensing electrode 100 are connected, and the combined sensing electrode 100 after connection is then connected to a touch detection circuit 111 of the display touch integrated chip 110. This reduces the number of detection circuits connected to the display touch integrated chip 110. It should be noted that... Figure 5 The connection of one end of the combined sensing electrode 100 to the touch detection circuit 111 is merely for illustrative purposes and does not limit other connection methods. Only two first ends are identified in the switch module 112; in actual applications, multiple first ends can be provided according to actual needs. The technical solution in this embodiment improves the performance of the touch detection circuit 111 and further enhances detection efficiency.

[0078] In one embodiment, the plurality of independent sensing electrodes 101 in the same combined sensing electrode 100 are disconnected from each other, and each of the independent sensing electrodes 101 in the same combined sensing electrode 100 is connected to a plurality of input terminals 113 connected to the same touch detection circuit 111.

[0079] In this embodiment, as Figure 6As shown, taking a combined sensing electrode 100 comprising two independent sensing electrodes 101 as an example, the two independent sensing electrodes 101 are not connected, but are connected to the two input terminals 113 of the touch detection circuit 111. That is, the touch detection circuit 111 detects the combined data of the two independent sensing electrodes 101. This reduces the number of detection circuits in the touch detection circuit 111 without connecting individual independent sensing electrodes 101 to the touch detection circuit, simplifying the structure of the touch detection circuit 111 and reducing its area.

[0080] In one embodiment, such as Figure 7 and Figure 8 As shown, a touch detection method is provided. This embodiment illustrates the application of this method to a terminal. In this embodiment, the method includes the following steps:

[0081] Step S102: Determine the target combined electrode 602 based on the sensing detection data of each combined sensing electrode 100 in the touch display screen. The target combined electrode 602 is one of the combined sensing electrodes 100 that is being touched.

[0082] Specifically, when the sensing detection data of one of the combined sensing electrodes 100 in the touch display screen is significantly different from the others, the target combined electrode 602 is determined to be one of the combined sensing electrodes 100 that has been touched.

[0083] Step S202: Obtain the sensing analysis data of each independent sensing electrode 101 in the target region 601 based on the sensing detection data of each of the combined sensing electrodes 100 in the target region 601. The target region 601 includes the target combined electrode 602 and a plurality of combined sensing electrodes 100 surrounding the target combined electrode 602.

[0084] Specifically, the touch integrated chip 110 only detects the sensing data of the combined sensing electrodes 100. To accurately determine which specific independent sensing electrode 101 in the touch screen is being touched, the acquired sensing data needs to be decomposed and calculated to obtain the sensing analysis data of the single independent sensing electrode 101 at the touched position.

[0085] Step S302: Obtain touch coordinates based on the multiple sensor analysis data.

[0086] In the above-described touch detection method, in order to accurately determine the position of the touched independent sensing electrode 101, it is necessary to combine the sensing analysis data and the sensing data of the multiple combined sensing electrodes 100 surrounding the target combined electrode 602 for calculation, thereby improving the accuracy of detection.

[0087] In one embodiment, the first direction is the column direction and the second direction is the row direction. When the combined sensing electrode 100 includes two independent sensing electrodes 101, the acquisition of sensing analysis data of each independent sensing electrode 101 in the target area 601 includes:

[0088] When the independent sensing electrode 101 for which the sensing analysis data is to be acquired is located at the outermost edge of the target region 601, the sensing analysis data of the independent sensing electrode 101 is obtained using the following formula based on the sensing detection data of the first related combined electrode set 604 in the target region 601:

[0089]

[0090] Wherein, the first related combined electrode set 604 is adjacent to the sensing electrode for which the sensing analysis data is to be acquired in the row direction, and partially overlaps with the sensing electrode for which the sensing analysis data is to be acquired in the column direction; This refers to the column number where the combined sensing electrode 100 is located. Let n be the row number of the combined sensing electrode 100, and n be the row number of the independent sensing electrode 101 in the combined sensing electrode 100. When n=1, ... = When n=2, = +1; The induction analysis data is for the independent sensing electrode 101; This refers to the sensing detection data of the combined sensing electrode 100. Figure 8 The first related combined electrode set 604 in the middle includes the first related combined electrodes within the two dotted boxes.

[0091] In this embodiment, as Figure 8 As shown, to clearly illustrate the logic expressed in the above formula, Figure 8 The touch detection circuit and the connection lines between each combined sensing electrode 100 and the touch detection circuit are omitted, and are instead... Figure 5 The connection relationship of the combined sensing electrodes 100 shown is illustrated using an example. When the independent sensing electrode 101 for which the sensing analysis data is to be acquired is located in the leftmost column of the target region 601, that is... Figure 8 When one of the independent sensing electrodes 101 in the combined sensing electrode 603 is used, the numerator in the formula is When the independent sensing electrode 101 for acquiring the sensing analysis data is located in the leftmost column of the target region 601, the numerator in the formula is... For example, obtaining the sensing analysis data of the independent sensing electrode 101 requires calculation using the sensing detection data of two first related combined electrodes, where the target combined electrode is also a first related combined electrode. This method improves the accuracy of the sensing analysis data.

[0092] In one embodiment, such as Figure 9 As shown, when the independent sensing electrode 101 for acquiring the sensing analysis data is located outside the outermost part of the target region 601, the sensing analysis data of the independent sensing electrode 101 is obtained using the following formula based on the sensing detection data of the second related combined electrode set 702 in the target region 601:

[0093]

[0094] in, Figure 9 The second relevant combined electrode set 702 includes four second relevant combined electrodes marked with dashed boxes. The second relevant combined electrode set 702 is adjacent to the sensing electrode for which the sensing analysis data is to be acquired in the row direction, and partially overlaps with the sensing electrode for which the sensing analysis data is to be acquired in the column direction; when n=1, = When n=2, = .

[0095] In this embodiment, refer again Figure 9 Taking the target combined electrode and the sensing electrode for the sensing analysis data to be acquired as the same combined sensing electrode, and a combined sensing electrode 100 including two independent sensing electrodes 101 as an example, the two can also be different combined independent sensing electrodes 101 in actual use. In this case, the sensing analysis data of the sensing electrode in the combined sensing electrode 701 needs to be calculated by the sensing detection data of the second related combined electrode set 702. Through the above method, the sensing analysis data of the non-outermost sensing electrode located in the target area 601 can be accurately calculated.

[0096] In one embodiment, such as Figure 10As shown, each independent sensing electrode 101 in the touch display screen is configured with a global coordinate 801 under a global coordinate 801 system, and each independent sensing electrode 101 covers multiple touch points 803. The step of obtaining touch coordinates based on multiple sensing analysis data includes: determining a target sensing electrode 804 based on multiple sensing analysis data, wherein the target sensing electrode 804 is one of the independent sensing electrodes 101 that is being touched; establishing a target coordinate system 802 with the target sensing electrode 804 as the center, and obtaining the relative positional relationship between the target coordinate system 802 and the global coordinate 801 system; obtaining the target coordinates of the actual touch point 803 under the target coordinate system 802 based on multiple sensing analysis data, and obtaining the global coordinates 801 of the actual touch point 803 as the touch coordinates based on the relative positional relationship and the target coordinates.

[0097] In this embodiment, by establishing a target coordinate system 802, the calculation process for obtaining touch coordinates is simplified. The sensing analysis data of the target sensing electrode 804 differs significantly from the sensing analysis data of the other independent sensing electrodes 101. Thus, the target sensing electrode 804 can be accurately determined using multiple sensing analysis data.

[0098] In one embodiment, when the target area 601 includes 2m rows and 2n+1 columns of independent sensing electrodes 101, the step of obtaining the target coordinates of the actual touch point 803 in the target coordinate system 802 based on multiple sensing analysis data, and obtaining the global coordinates 801 of the actual touch point 803 as the touch coordinates based on the relative positional relationship and the target coordinates, includes:

[0099]

[0100]

[0101] in,( (a, b) represents the coordinates of each independent sensing electrode 101 in the target coordinate system 802; (a, b) represents the coordinates of each independent sensing electrode 101 in the global coordinate system 801. This is the induction analysis data for the independent sensing electrode 101.

[0102] In this embodiment, the above-mentioned formula for calculating touch coordinates averages the data of all independent sensing electrodes 101 within the target area 601. Since the data of each independent sensing electrode 101 is multiplied by its coordinates in the target coordinate system 802, the most accurate touch coordinates can be obtained, which improves the accuracy of detecting the actual touch point 803 position.

[0103] It should be understood that although the steps in the flowcharts of the embodiments described above are shown sequentially according to the arrows, these steps are not necessarily executed in the order indicated by the arrows. Unless explicitly stated herein, there is no strict order restriction on the execution of these steps, and they can be executed in other orders. Moreover, at least some steps in the flowcharts of the embodiments described above may include multiple steps or multiple stages. These steps or stages are not necessarily completed at the same time, but can be executed at different times. The execution order of these steps or stages is not necessarily sequential, but can be performed alternately or in turn with other steps or at least some of the steps or stages of other steps.

[0104] Based on the same inventive concept, this application also provides a touch detection device for implementing the touch detection method described above. The solution provided by this device is similar to the implementation described in the above method; therefore, the specific limitations in one or more touch detection device embodiments provided below can be found in the limitations of the touch detection method described above, and will not be repeated here.

[0105] In one embodiment, such as Figure 11 As shown, a touch detection device 900 is provided, including: a determination module 910, a first execution module 920, and a second execution module 930.

[0106] The determining module 910 is used to determine the target combined electrode 602 based on the sensing detection data of each combined sensing electrode 100 in the touch display screen, wherein the target combined electrode 602 is one of the combined sensing electrodes 100 that is being touched.

[0107] The first execution module 920 is used to obtain the sensing analysis data of each independent sensing electrode 101 in the target region 601 based on the sensing detection data of each of the combined sensing electrodes 100 in the target region 601. The target region 601 includes the target combined electrode 602 and a plurality of combined sensing electrodes 100 surrounding the target combined electrode 602.

[0108] The second execution module 930 is used to obtain touch coordinates based on multiple sensing analysis data.

[0109] In one embodiment, the first direction is a column direction and the second direction is a row direction. When the combined sensing electrode 100 includes two independent sensing electrodes 101, the first execution module 920 is further configured to, when the independent sensing electrode 101 for which the sensing analysis data is to be acquired is located at the outermost edge of the target region 601, obtain the sensing analysis data of the independent sensing electrode 101 using the following formula based on the sensing detection data of the two first related combined electrode sets 604 in the target region 601:

[0110]

[0111] Wherein, the first related combined electrode set 604 is adjacent to the sensing electrode for which the sensing analysis data is to be acquired in the row direction, and partially overlaps with the sensing electrode for which the sensing analysis data is to be acquired in the column direction; This refers to the column number where the combined sensing electrode 100 is located.
