[0022] See also Figure 1 , Figure 1 The touch control method according to the embodiment of the present invention is a flow chart of the touch control method provided by the embodiment of the present invention. The touch control method according to the embodiment of the present invention can be applied to a touch control device, which can be a tablet computer, a smart phone, a notebook with a touch control function, etc., and is used to correct the effective touch point when the touch control device generates electromagnetic interference to ensure that the touch action is triggered normally. Figure 1 As shown, the method includes steps S110 to S130.

[0023] S110: If it is detected that a touch action of the touch control system is triggered, a current effective touch point corresponding to the touch action is obtained.

[0024] In an embodiment of the present invention, a touch device is taken as an example of a smart phone, which has a touch screen, and the touch screen can be a capacitive touch screen. When the smart phone is in a normal state, the touch actions performed by the user through the touch screen can be normally fed back. For example, the user turns the page of the smart phone by sliding, or performs spelling operations by touch. When the smart phone is interfered by EFT pulses, touch anomalies will occur. For example, when the user is drawing a line on the touch screen with his finger, the touch screen may suddenly become unresponsive, or a disconnection may occur, that is, when the finger continues to draw a line on the screen, the line is discontinuous or a breakpoint occurs. In addition, the touch system may also experience abnormal phenomena such as failure, jumping points, and flying lines, which will seriously affect the user experience.

[0025] In view of the above problems, the present invention provides a touch control method, which can be applied to the above-mentioned smart phones and other touch devices with touch screens, and can monitor the user's touch operation in real time. Specifically, when it is detected that the touch action of the touch system is triggered, the current touch effective point corresponding to the touch action is obtained. The touch system refers to a system composed of a touch screen and a touch MCU. The effective touch point refers to the real and effective touch position point confirmed by the touch system and the control system when the user performs a touch operation.

[0026] In some embodiments, such as this embodiment, step S110 may include the following steps:

[0027] Acquire a plurality of touch points corresponding to the touch action of the touch control system, and acquire touch point reporting data and touch original data of the touch points;

[0028] A valid touch point among the plurality of touch points is confirmed according to the touch point reporting data and the touch original data.

[0029] In the embodiment of the present invention, when the user touches the touch screen, the touch IC will periodically collect the capacitance value signal change of the touch screen through the ADC, and after being processed by the touch MCU, form the touch point data and report it to the control system. At the same time, the touch IC will also periodically collect the original data of the capacitance value signal that has not been processed by the touch MCU, and these original data constitute the touch original data. That is, the touch point data is the data processed by the MCU, and the touch original data is the data that has not been processed by the MCU.

[0030] After obtaining the touch point reporting data and the original touch data, the touch point reporting data and the original touch data can be compared to confirm the effective touch point. For example, based on the original touch data, the difference between the touch point reporting data and the original touch data is compared. When the difference exceeds the preset threshold, it is considered an invalid touch point. When the difference is within the preset threshold, it is considered a valid touch point. When the user touches, multiple touch points can be generated. Each touch point includes touch point reporting data and original touch data. It can be confirmed whether the touch point is a valid touch point or an invalid touch point based on the touch point reporting data and the original touch data.

[0031] In some embodiments, such as the present embodiment, the step of confirming a valid touch point among the plurality of touch points according to the touch point reporting data and the touch original data may include the following steps:

[0032] confirming the difference between the touch point reporting data and the touch original data;

[0033] The touch point whose difference between the touch point reporting data and the touch original data is less than a preset threshold is set as the touch effective point;

[0034] A touch point whose difference between the touch point reporting data and the touch original data is greater than or equal to the preset threshold is set as a touch invalid point.

[0035] In an embodiment of the present invention, when a user performs a touch control, the touch control system will collect the capacitance signal, and the collected capacitance value signal will be processed by the touch control MCU to form touch point reporting data. These data contain information such as the specific location of the user touching the screen and the touch force. At the same time, the driver board will also actively obtain the original data of the capacitance value signal periodically collected by the touch control IC and not processed by the touch control MCU. These data are read directly from the touch IC without any processing or filtering. It can be confirmed whether the touch point is a valid touch point or an invalid touch point by comparing the touch point reporting data and the touch original data.

[0036] For example, when a user touches a specific position on the screen, the touch IC collects the capacitance value signal change at that position and generates touch point reporting data. At the same time, the driver board also obtains the corresponding original touch data. If the touch point reporting data is highly consistent with the original touch data in terms of position, signal strength, etc., or the difference between the two is less than the preset threshold, the touch point can be set as a touch valid point. If the touch point reporting data is highly inconsistent with the original touch data in terms of position, signal strength, etc., or the difference between the two is greater than or equal to the preset threshold, the touch point can be set as a touch invalid point. In addition, the touch point reporting data can include capacitance signal change data, and it can also be confirmed whether the touch point is a touch valid point by comparing the capacitance signal change data with the preset parameter threshold. For example, when the difference between the capacitance signal change data and the preset parameter threshold is greater than a certain threshold, the touch point is regarded as a touch valid point, otherwise it is a touch invalid point.

[0037] S120, obtaining a current working state of the touch control device, and determining whether the touch control device has electromagnetic interference according to the working state.

[0038] In the embodiment of the present invention, the working state of the touch device refers to whether the touch state of the touch device is normal. When the touch device is in a normal state, it indicates that no electromagnetic interference occurs and the touch operation can be responded normally. When the touch device is in an abnormal state, it indicates that electromagnetic interference occurs and the touch needs to be corrected.

[0039] In some embodiments, such as this embodiment, the step of obtaining the current working state of the touch device may include the following steps:

[0040] Acquire instruction data of the touch control device and communication level data corresponding to the instruction data;

[0041] The working status is acquired according to the instruction data and the communication level data.

[0042] In the embodiment of the present invention, the instruction data mainly refers to whether the system has issued interrupt, reset and other working instruction requirements to the touch IC, the communication level data mainly refers to the level changes of interrupt INT, reset RST, clock SCL, data SDA, power supply VCC, and ground signal GND, and the content included in the communication level data is mainly determined by the communication protocol of the touch device. For example, if it is IIC communication, the communication level data mainly refers to the level changes of interrupt INT, reset RST, clock SCL, data SDA, power supply VCC, and ground signal GND. If it is USB communication, the communication level data refers to the level changes of power supply VCC, ground signal GND, data positive D+, and data negative D-.

[0043] After the command data and the communication level data are acquired, the working state of the touch device is determined according to whether the command data and the communication level data are consistent.

[0044] In some embodiments, such as the present embodiment, the step of acquiring the working status according to the instruction data and the communication level data may include the following steps:

[0045] If the level data corresponding to the instruction data is consistent with the communication level data, confirming that the working state is a normal state;

[0046] If the level data corresponding to the instruction data is inconsistent with the communication level data, it is confirmed that the working state is an abnormal state.

[0047] In the embodiment of the present invention, when the instruction data is issued, but the communication level data associated with the instruction data does not change in level, it indicates that the instruction data is inconsistent with the communication level data, and the touch control device is subject to electromagnetic interference, that is, EFT pulse interference. When the instruction data is consistent with the communication level data, the touch control device is in a normal state and is not subject to electromagnetic interference.

[0048] For example, when the system sends an interrupt command to the touch IC, the driver board will record the command data. At the same time, the system will detect the level change of the corresponding interrupt INT signal on the IIC communication line to ensure that the change is consistent with the command data. If the command data requires the touch IC to be interrupted, but the interrupt INT signal on the IIC communication line does not have a corresponding level change (or the change is not as expected), it indicates that the touch device is interfered by the EFT pulse.

[0049] In some embodiments, such as the present embodiment, the step of determining whether the touch device has electromagnetic interference according to the working state may include the following steps:

[0050] If the current working state is a normal state, confirming that the touch device does not have the electromagnetic interference;

[0051] If the current working state is an abnormal state, it is confirmed that the electromagnetic interference exists in the touch control device.

[0052] In the embodiment of the present invention, when the touch device is in a normal state, it indicates that the touch device can respond to touch operations normally and there is no electromagnetic interference. When the touch device is in an abnormal state, it indicates that there is electromagnetic interference in the touch device and the touch action needs to be corrected.

[0053] S130: If the electromagnetic interference exists in the touch device, the effective touch point is corrected so that the touch action can be triggered normally.

[0054] In the embodiment of the present invention, the purpose of correcting the effective touch point is to ensure that the touch device will not be affected by electromagnetic interference and cause touch failure or abnormality. For example, when the instruction data is inconsistent with the communication level data, the level of the communication level data can be adjusted to match the instruction data to ensure that the touch action can be responded to normally.

[0055] For example, if the touch device is running in an environment with EFT pulse interference, and the user draws a line on the screen, the IIC communication of the touch system will be abnormal due to the existence of EFT pulse interference, resulting in abnormal touch data and disconnection. In this case, if the touch device can be corrected, the touch point data and touch raw data will be obtained to confirm the effective touch point, and then the command data and communication level data will be obtained to confirm that the touch device has electromagnetic interference. The communication level data will be corrected according to the command data to ensure that the effective touch point can be responded normally. In actual practice, disconnection will occur. After correction, the user can draw normally without disconnection.
