Obviously, the described exemplary embodiments are only part of the embodiments of the present application, rather than all the embodiments.

[0053] It should be noted that the brief description of terms in this application is only for the convenience of understanding the embodiments described below, and is not intended to limit the embodiments of this application.

[0055] Touch devices can use capacitive screens to achieve touch control. Capacitive screens, also known as capacitive touch screens, are touch screens that work using the human body's current induction. Figure 1is a schematic diagram of a hardware configuration of a touch control device 100, such as Figure 1 As shown, the touch control device 100 uses a capacitive screen for touch control, including a capacitive screen 175 and a touch control unit 176. The capacitive screen includes a touch driving electrode layer and a touch sensing electrode layer.

[0056] Figure 2 is a schematic diagram of the relationship between a touch driving electrode layer and a touch sensing electrode layer, such as Figure 2 As shown, the touch driving electrode layer is provided with multiple rows of touch driving electrodes (also called touch driving channels) Tx, and the touch sensing electrode layer is provided with multiple rows of touch sensing electrodes (also called touch sensing channels) Rx. Figure 2 The schematic diagram takes the touch driving electrode layer as an example, which includes 9 rows of touch driving electrodes and 12 rows of touch sensing electrodes. The multiple rows of touch driving electrodes Tx and the multiple rows of touch sensing electrodes Rx are vertically interlaced with each other, and each intersection formed is a touch node on the capacitive screen that can be independently controlled.

[0057] Continue to refer to Figure 1 In some embodiments, the touch control device 100 may further include a controller 150, a communicator 120, an input / output interface 155 (eg Figure 1 ), and at least one of the memory 160.

[0058] like Figure 1 As shown, the controller 150 includes at least one of a random access memory 151 (Random Access Memory, RAM), a read-only memory 152 (Read-Only Memory, ROM), a central processing unit 154 (Central Processing Unit, CPU), and a communication bus 156 (Bus). The communication bus connects various components.

[0059] In some embodiments, RAM 151 is used to store temporary data for the operating system or other running programs.

[0060] In some embodiments, ROM 152 is used to store various system startup instructions. In some embodiments, ROM 152 is used to store a basic input and output system, called a basic input and output system (BIOS), which is used to complete the power-on self-test of the system, the initialization of each functional module in the system, the basic input / output driver of the system, and the booting of the operating system.

[0061] In some embodiments, when receiving the power-on signal, the power of the touch device 100 starts to start, and the CPU runs the system startup instruction in the ROM 152, and copies the temporary data of the operating system stored in the memory to the RAM 151, so as to start or run the operating system. When the operating system is started, the CPU copies the temporary data of various applications in the memory to the RAM 151. Then, various applications are started or run.

[0062] In some embodiments, the CPU processor 154 is used to execute operating system and application instructions stored in the memory, and to execute various applications, data and content according to various interactive instructions received from external input, so as to finally display and play various audio and video contents.

[0063] In some exemplary embodiments, the CPU processor 154 may include multiple processors. The multiple processors may include a main processor and one or more sub-processors. The main processor is used to perform some operations of the touch device 200 in the pre-power-on mode and / or display the screen in the normal mode. The one or more sub-processors are used for an operation in the standby mode and other states.

[0064] Capacitive screen 175 can be used for image and / or handwriting display. In some embodiments, capacitive screen 175 can include a capacitive screen component for presenting a picture. In some embodiments, depending on the type of capacitive screen 175, a driving component for driving the display is also included. In some embodiments, capacitive screen 175 is a projection capacitive screen, and can also include a projection device and a projection screen.

[0065] In some embodiments, the display panel of the capacitive screen 175 can adopt a liquid crystal display (LCD), an organic light-emitting diode (OLED), an active matrix organic light-emitting diode or an active matrix organic light-emitting diode (AMOLED), a flexible light-emitting diode (FLED), Miniled, MicroLed, Micro-oLed, a quantum dot light emitting diode (QLED), etc.

[0066] In some embodiments, the communicator 120 is a component for communicating with an external device or an external server according to various communication protocol types. For example, the communicator may include at least one of a Wifi chip, a Bluetooth communication protocol chip, a wired Ethernet communication protocol chip, and other network communication protocol chips or a near field communication protocol chip, and an infrared receiver. In some embodiments, the touch device 100 can establish control signal and data signal transmission and reception between the communicator 120 and the external device or content providing device.

[0067] In some embodiments, Figure 1 As shown, the input / output interface 155 is configured to perform data transmission between the controller 150 and other external devices or other controllers 150, such as receiving video signal data and audio signal data, or command instruction data from external devices.

[0068] In some embodiments, the memory 160 may include and store various software modules for driving the touch device 100 , such as at least one of a basic module, a detection module, a communication module, a display control module, a browser module, and various service modules.

[0069] In some embodiments, the touch control device 100 may further include a touch control panel on which a touch control unit 176 is integrated.

[0070] When the touch device is in working state, the touch control unit sends a scanning signal to each row of touch drive electrodes, and obtains the touch sensing signal of each touch node through the touch sensing electrode. The touch sensing signal is used to characterize the touch state of the current touch node, that is, whether the object (such as a finger, a stylus, etc.) touches the position or edge position of the touch node. When the object touches the position or edge position of the touch feedback point, the coupling between the two electrodes near the touch node is affected, thereby causing a slight change in the capacitance between the two electrodes, resulting in a change in the touch sensing signal of the touch node currently obtained. Subsequently, the touch control unit can generate a tactile feedback signal based on the touch sensing signal to achieve feedback on the touch action of the object.

[0071] At present, during the production process or the bonding process of the capacitive screen, foreign matter may be doped into the touch drive electrode layer and the touch sensing electrode layer, which may cause abnormal spacing between adjacent electrode layers, or uneven etching, which will cause the capacitive screen to be uneven in this area. However, the flatness of the capacitive screen has an important influence on the accurate acquisition of the touch sensing signal by the touch control unit. If the flatness of a certain area of ​​the capacitive screen is poor, the amount of touch sensing signals obtained in this area will change, affecting the subsequent algorithm's scanning and processing of the entire screen. This may cause abnormal jump point phenomenon in uneven areas, resulting in poor touch effect. The abnormal jump point phenomenon mentioned here refers to abnormal touch behavior that is not controlled by the user on the screen of the touch device. For example, when the user does not touch, the screen of the touch device automatically opens an application due to touch abnormality.

[0072] In order to reduce the impact of flatness on the touch effect of touch devices, the touch drive electrode layer and the touch sensing electrode layer are usually thickened to reduce the impact of foreign matter on flatness during the production process. However, when the foreign matter is small, this method can improve the flatness of the capacitive screen to a certain extent, but when the foreign matter is large, the effect of thickening the electrode layer on improving the flatness of the capacitive screen is poor, and there will still be many uneven areas on the capacitive screen, causing differences in touch sensing signals. Moreover, thicker electrode layers will inevitably lead to an increase in production costs.

[0073] In view of this, the present application provides a touch control method, which does not control the production process during the production process, but adjusts the touch sensing signal of the capacitive screen in the uneven area during the use of the touch device, thereby reducing the difference in touch sensing signals caused by the unevenness of the capacitive screen. In this way, the difference in touch sensing signals caused by the unevenness of the capacitive screen can be better improved, the touch performance of the touch device can be improved, and the production cost can be reduced.

[0074] The technical solution of the present application is described in detail below in conjunction with specific embodiments. The following specific embodiments can be combined with each other, and the same or similar concepts or processes may not be described in detail in some embodiments.

[0075] On the basis of the above touch device structure, the capacitive screen of the touch device provided in the present application includes M partitions, each partition includes N touch nodes; M and N are both integers greater than 1.

[0076] The executor of the touch method provided in the present application is a touch control unit, which may be a control chip on a touch panel, and the touch panel may be, for example, a circuit board used for touch control in a touch device; or, the touch control unit may be a processor of a touch device, which is not limited in the present application.

[0077] Figure 3 This is a schematic diagram of the process of the first touch control method provided by this application. Figure 3 As shown, the method may include the following steps:

[0078] S101: Acquire a touch sensing signal of a touch node in a target partition.

[0079] The target partition may be any one or more of the M partitions of the capacitive screen. The touch sensing signal of the touch node is a sensing signal that can represent the touch condition of the capacitive screen, for example, it may be a capacitance, voltage, or current signal.

[0080] In this step, the touch module obtains the touch sensing signal of the touch node of the target partition, so that touch recognition can be performed according to the touch sensing signal later.

[0081] There is a first target touch node, which is a touch node in the target partition whose touch sensing signal difference with the adjacent touch node in the no-touch state is greater than or equal to a preset threshold. The present application does not limit the specific value of the preset threshold, and those skilled in the art can determine it according to actual conditions. The present application does not limit whether the adjacent touch node is specifically one adjacent touch node or multiple adjacent touch nodes, nor does it limit whether the adjacent node is in the front, back, left, or right direction of the touch node.

[0082] The difference between the touch sensing signal of a touch node in a normal flatness area and an adjacent touch node in a non-touch state is usually small, indicating that the flatness is good. If the difference between the touch sensing signal of a touch node and an adjacent touch node in a non-touch state is large, it indicates that the flatness of the capacitive screen where the touch node is located is poor. Therefore, the first target touch node is a touch node with poor flatness, and the touch sensing signal actually obtained through the touch node is different from the touch sensing signal that should be obtained.

[0083] If the number of the first target touch nodes in the target partition is greater than the preset number, it indicates that the number of abnormal touch nodes in the target partition due to unevenness is large, and the target partition is an uneven partition on the capacitive screen, and step S102 is executed. This application does not limit the specific value of the preset number, and those skilled in the art can set it according to actual conditions.

[0084] If the number of first target touch nodes in the target partition is less than or equal to the preset number, step S103 is executed.

[0085] S102: adjusting the touch sensing signal of the touch node according to the adjustment amount of the touch sensing signal of the target partition, and performing touch recognition according to the adjusted touch sensing signal of the touch node.

[0086] The adjustment amount of the above touch sensing signal is used to reduce the difference of the touch sensing signal caused by the unevenness of the capacitive screen. Exemplarily, the adjustment amount of the above touch sensing signal can be, for example, the difference between the average value of the touch sensing signal of the normal touch node of the target partition and the average value of the touch sensing signal of the abnormal touch node; or, it can be the ratio of the average value of the touch sensing signal of the normal touch node of the target partition to the average value of the touch sensing signal of the abnormal touch node. Since the average value of the touch sensing signal of the normal touch node of the target partition and the average value of the touch sensing signal of the abnormal touch node can reflect the flatness of the capacitive screen of the target partition, and the relationship between the two can reflect the relationship between the touch sensing signal of the abnormal touch sensing node actually measured in the area and the touch sensing signal of the abnormal touch sensing node to be measured. Therefore, through the above adjustment amount, the touch sensing signal of the touch node can be adjusted.

[0087] Subsequently, the touch control unit performs touch recognition according to the touch sensing signal adjusted by the touch node to realize the touch function of the touch device. Specifically, the present application does not limit the specific implementation method of the touch control unit performing touch recognition according to the touch sensing signal adjusted by the touch node, which can be any implementation method in the prior art.

[0088] S103: Perform touch recognition according to the touch sensing signal of the touch node.

[0089] Since the number of first target touch nodes in the target partition is less than or equal to the preset number, indicating that the target partition is a flat partition, in this step, the touch control unit directly performs touch recognition according to the touch sensing signal of the touch node, that is, the normal touch function of the touch device can be realized.

[0090] In this embodiment, the touch control unit obtains touch sensing signals of touch nodes in the target partition; if the number of first target touch nodes in the target partition is greater than a preset number, the touch sensing signals of the touch nodes are adjusted according to the adjustment amount of the touch sensing signals of the target partition, and touch recognition is performed according to the adjusted touch sensing signals of the touch nodes; the first target touch node is a touch node in the target partition whose difference between the touch sensing signals and those of adjacent touch nodes in a no-touch state is greater than or equal to a preset threshold; if the number of first target touch nodes in the target partition is less than or equal to the preset number, touch recognition is performed according to the touch sensing signals of the touch nodes.

[0091] Since the adjustment amount of the touch sensing signal can reduce the difference of the touch sensing signal caused by the unevenness of the capacitive screen, the touch sensing signal of the uneven partition can be adjusted by using the adjustment amount of the touch sensing signal. Therefore, the touch sensing signal of any uneven partition can be adjusted directly during the use of the touch device, without reducing the occurrence of abnormal jump point phenomenon during the use of the touch device by thickening the capacitive screen during the production process as in the prior art. Therefore, in this way, the touch accuracy can be improved, the touch effect can be optimized, and the production cost can be reduced.

[0092] Before acquiring the touch sensing signal of the touch node of the target partition, the touch control unit may first determine whether the target partition is an uneven partition. The following specifically describes how to determine whether the target partition is an uneven partition. Figure 4 A schematic diagram of the flow of the second touch control method provided in this application, such as Figure 4 As shown, the method may include the following steps:

[0093] S201: Acquire a touch sensing signal of a touch node in a no-touch state, and a difference between touch sensing signals of adjacent touch nodes in a no-touch state.

[0094] The non-touch state is a touch node state when there is no object performing touch control on the touch device.

[0095] The present application does not limit the triggering conditions for the touch control unit to obtain the touch sensing signal of the touch node in the no-touch state, and the difference between the touch sensing signals of adjacent touch nodes in the no-touch state. Exemplarily, the touch control unit may, for example, obtain the signal sensing amount of the touch sensing signal of the touch node in the no-touch state after obtaining the indication of the user input to determine whether the target partition is an uneven partition of the capacitive screen. The above indication may be obtained, for example, by the user pressing a physical button of the touch device, or touching the capacitive screen of the touch device, and the touch control unit obtains the indication. Alternatively, the touch control unit may periodically obtain the touch sensing signal of the touch node in the no-touch state, and the touch sensing signal of the adjacent touch nodes in the no-touch state to determine whether the target partition is an uneven partition of the capacitive screen. The present application does not limit the specific value of the period, and those skilled in the art may set it according to needs.

[0096] Continue to refer to Figure 2 For example, taking an adjacent touch node as a touch node to the right of the current touch node (with the reader's vision as a reference), the touch control unit subtracts the touch sensing signal value of the touch node in the no-touch state from the touch sensing signal value of the adjacent touch node in the no-touch state to obtain the difference between the two.

[0097] If the difference is greater than or equal to the preset threshold, it indicates that the flatness of the position where the touch node is located is poor, and there is a large difference between the touch sensing signal obtained by the touch node and the touch sensing signal obtained by the touch node in a normal state, then step S202 is executed.

[0098] If the difference is less than the preset threshold, it indicates that the flatness of the position where the touch node is located is good, and the touch sensing signal obtained by the touch node is slightly different from the touch sensing signal obtained by the touch node in a normal state, that is, the touch node is a touch node in a flat area.

[0099] S202: Use the touch node as the first target touch node.

[0100] In this step, the touch control unit takes the touch node as the first target touch node, that is, marks the touch node as a touch node with poor flatness. If the number of first target touch nodes in the target area is small, it may not affect the touch effect of the area. However, if there are more first target touch node data in the target area, it will affect the touch effect of the area. Therefore, the relationship between the number of first target touch nodes in the target area and the preset number is determined. If the number of first target touch nodes in the target partition is greater than the preset number, it indicates that the number of first target touch nodes in the target area is large and the flatness is poor, which will affect the touch effect of the target area, and then execute step S203.

[0101] If the number of first target touch nodes in the target partition is less than or equal to the preset number, it indicates that the number of first target touch nodes in the target area is small and the flatness is good, which will not affect the touch effect of the target area, and then step S204 is executed.

[0102] S203: Determine that the target partition is an uneven partition.

[0103] S204: Determine that the target partition is a flat partition.

[0104] In this embodiment, the touch control unit obtains the touch sensing signal of the touch node in the non-touch state, and then determines whether the target partition is an uneven partition of the capacitive screen according to the touch sensing signal of the touch node in the non-touch state and the touch sensing signal of the adjacent touch node. Since the touch sensing signal of the abnormal touch node in the uneven partition must be greatly different from the touch sensing signal of the adjacent touch node in the non-touch state, the above method can accurately determine whether the target partition is an uneven partition.

[0105] Optionally, if the target partition is an uneven partition, before acquiring the touch sensing signal of the touch node of the target partition, the touch control unit first acquires the adjustment amount of the touch sensing signal of the target partition. The following describes how to acquire the adjustment amount of the touch sensing signal through a specific embodiment. Figure 5 A schematic diagram of the process flow of the third touch control method provided in this application, such as Figure 5 As shown, the method may include the following steps:

[0106] S301: Obtain an average value of a first touch sensing signal of a first target touch node in a target partition.

[0107] In this step, the touch control unit obtains the average value of the first touch sensing signal of the first target touch node in the target partition, that is, obtains the average value of the touch sensing signal of the touch node with abnormal touch sensing signal in the target partition.

[0108] S302: Obtain an average value of second touch sensing signals of second target touch nodes other than the first target touch node in the target partition.

[0109] In this step, the touch control unit obtains the average value of the second touch sensing signals of the second target touch nodes in the target partition, that is, obtains the average value of the touch sensing signals of the touch nodes with normal touch sensing signals in the target partition.

[0110] S303: Obtain an adjustment amount of the touch sensing signal according to an average value of the first signal sensing amount and an average value of the second signal sensing amount.

[0111] In this step, the touch control unit obtains the adjustment amount of the touch sensing signal according to the average value of the first signal sensing amount and the average value of the second signal sensing amount, and then the touch sensing signal of the uneven area of ​​the capacitive screen can be adjusted according to the adjustment amount.

[0112] In one implementation, the touch control unit divides the average value of the first touch sensing signal by the average value of the second touch sensing signal to obtain an adjustment amount of the touch sensing signal. Since the average value of the first touch sensing signal divided by the average value of the second touch sensing signal can represent the overall deviation degree of the touch sensing signals of the normal touch nodes and the abnormal touch nodes in the target area as a whole, the value obtained by dividing the two is used as the adjustment amount of the touch sensing signal, and the deviation of the touch sensing signal of the first target touch node in the target partition can be adjusted accordingly.

[0113] In another implementation, the touch control unit subtracts the average value of the first touch sensing signal from the average value of the second touch sensing signal to obtain an adjustment amount of the touch sensing signal. Since the average value of the first touch sensing signal is subtracted from the average value of the second touch sensing signal, the overall difference between the touch sensing signals of the normal touch nodes and the abnormal touch nodes in the target area can be represented as a whole. Therefore, the value obtained by subtracting the two is used as the adjustment amount of the touch sensing signal, and the deviation of the touch sensing signal of the first target touch node in the target partition can be adjusted accordingly.

[0114] In this embodiment, the touch control unit obtains the average value of the first touch sensing signal of the first target touch node in the target partition, and the average value of the second touch sensing signal of the second target touch node other than the first target touch node in the target partition; then, the adjustment amount of the touch sensing signal is obtained according to the average value of the first signal sensing amount and the average value of the second signal sensing amount. Since the first target touch node is the touch node with abnormal touch sensing signal, the average value of the first touch sensing signal of the first target touch node and the average value of the second touch sensing signal of the second target touch node other than the first target touch node in the target partition can represent the difference between the measured touch sensing signal of the abnormal touch node in the target partition and the touch sensing signal to be measured. Therefore, through the average value of the first signal sensing amount and the average value of the second signal sensing amount, the adjustment amount of the touch sensing signal can be obtained in the above manner, and then the touch sensing signal of the abnormal touch node in the target partition can be adjusted according to the adjustment amount, so as to improve the difference of the touch sensing signal caused by the unevenness of the capacitive screen and enhance the touch effect.

[0115] The following describes how to divide the capacitive screen into M partitions. Figure 6 A schematic diagram of a partitioning method provided for this application, such as Figure 6 As shown, the method may include the following steps:

[0116] S401: Acquire a first number of electrodes in a touch driving electrode layer and a second number of electrodes in a touch sensing electrode layer of a capacitive screen.

[0117] In this step, the touch control unit obtains the first number of electrodes of the touch driving electrode layer and the second number of electrodes of the touch sensing electrode layer, so as to divide the capacitive screen accordingly.

[0118] Exemplarily, the touch control unit may pre-store a first number of electrodes of the touch driving electrode layer and a second number of electrodes of the touch sensing electrode layer; or the touch control unit may obtain the first number and the second number from other storage media. The other storage media may be, for example, any disk or memory in the touch device.

[0119] S402. Determine a value of M according to the first quantity and the second quantity.

[0120] Since the point where the electrodes of the touch driving electrode layer intersect with the electrodes of the touch sensing layer is a touch node, the touch control unit determines whether the target partition is an uneven partition according to the touch sensing signal of the touch node. Therefore, in this step, the touch control unit determines the value of M according to the first number and the second number. Subsequently, the capacitive screen can be divided into M partitions according to the value of M.

[0121] In a possible implementation, the touch control unit obtains a common divisor of the first number and the second number. Then, the quotient of the first number and the common divisor is multiplied by the quotient of the second number and the common divisor to obtain the value of M. The first number and the second number may have one or more common divisors, and the present application does not limit which common divisor the touch control unit uses to obtain the value of M.

[0122] The present application does not limit the manner in which the touch control unit obtains the common divisor of the first number and the second number. For example, the touch control unit may store a preset common divisor of the first number and the second number; or, the touch control unit may obtain the common divisor from other storage media; or, the touch control unit calculates all common divisors of the first number and the second number based on the first number and the second number, and then selects the common divisor for determining the value of M in a preset manner. The preset manner mentioned here may be, for example, that the touch control unit selects the smallest common divisor greater than a preset value as the common divisor for determining the value of M.

[0123] For example, the number of electrodes in the touch driving electrode layer of an 86-inch touch device is 120, and the number of electrodes in the touch sensing electrode layer is 216, and one of the common divisors of the two is 12, then the value of M can be, for example, 10*18, that is, 180. In this way, the acquired M value can be used to equally divide the touch nodes of the touch device, so that each target area can have touch nodes with the same amount of data.

[0124] S403: Divide the capacitive screen into M partitions according to the value of M.

[0125] In this step, the touch control unit divides the capacitive screen into M partitions according to the value of M, so that the touch sensing signals of the touch nodes in different partitions can be adjusted based on the partitions later.

[0126] Exemplarily, the touch control unit may divide the capacitive screen into M partitions with N touch nodes, with the touch driving electrode as the length and the touch sensing electrode as the width.

[0127] In this embodiment, the touch control unit obtains the first number of electrodes of the touch drive electrode layer and the second number of electrodes of the touch sensing electrode layer. Then, according to the first number and the second number, the value of M is determined. Next, according to the value of M, the capacitive screen is divided into M partitions. Since the point where the electrode of the touch drive electrode layer intersects with the electrode of the touch sensing layer is a touch node, the touch control unit determines whether the target partition is an uneven partition of the capacitive screen according to the touch sensing signal of the touch node. Therefore, in this step, the touch control unit determines the value of M according to the first number and the second number, and divides the capacitive screen into M partitions according to the value of M, that is, a reasonable and convenient partitioning of the capacitive screen can be achieved, so that each of the M partitions can have the same number of touch nodes, so that the subsequent touch control unit can adjust the touch sensing signal of the touch node of the uneven partition of the capacitive screen.

[0131] The adjustment module 12 is further configured to perform touch recognition according to the touch sensing signals of the touch nodes if the number of the first target touch nodes in the target partition is less than or equal to a preset number.

If the number of the first target touch nodes of the target partition is less than or equal to the preset number, the target partition is determined to be a flat partition.

[0133] Optionally, the second acquisition module 14 is used to obtain an average value of a first touch sensing signal of a first target touch node in the target partition before the first acquisition module 11 obtains the touch sensing signal of the touch node in the target partition; obtain an average value of a second touch sensing signal of a second target touch node in the target partition except the first target touch node; and obtain an adjustment amount of the touch sensing signal according to the average value of the first touch sensing signal and the average value of the second touch sensing signal.
