Detailed Description

The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. It is to be understood that the specific embodiments described herein are merely illustrative of the relevant application and are not limiting of the application. It should be noted that, for the convenience of description, only the parts related to the related applications are shown in the drawings.

Touch screens (also called touch screens and touch panels) are inductive liquid crystal display devices capable of receiving input signals such as contacts. According to the working principle of the touch screen and the information transmission medium, the touch screen can be divided into a plurality of types, including a resistance type touch screen, a capacitance type touch screen, an infrared ray type touch screen, a surface acoustic wave touch screen and the like; among them, the capacitive touch screen is one of the most widely used touch screen types in the terminal device.

With the continuous development of terminal technology, the performance of a touch screen in terminal equipment is also greatly improved. However, the touch interruption phenomenon has been a problem that cannot be completely solved by the touch screen. For touch screens, the concept of the touch interruption phenomenon is general, and most of the touch screens mean that the touch screen operation is insensitive, for example, the direction joystick operation fails in the game process. The touch interruption phenomenon may be caused by various reasons, for example, a foreign object exists in the touch screen, a poor film of the touch screen, the terminal is charged by using a non-original charger or a data line, the terminal is not adapted to a third-party application program, and a reset mechanism of the touch screen has a defect.

At present, in the using process of a touch screen, when the difference exists between the self-capacitance data and the mutual capacitance data of the touch screen, the inconsistent type of the self-capacitance data and the mutual capacitance data is triggered, and the current solution is to immediately reset the touch screen and release an up event in advance; however, in practice, the object (such as a finger, a stylus, etc.) does not leave the touch screen, thereby causing the touch screen to be broken. For example, in some game scenes such as the glory of the royal, the fingers of the user do not leave the touch screen for a long time, so that the difference exists between the self-capacitance data and the mutual capacitance data, and when the type of inconsistency between the self-capacitance data and the mutual capacitance data is triggered, the fingers can be failed to slide on the touch screen due to the immediate reset of the touch screen; when the finger continues to slide on the touch screen, the touch screen is reset to cause sliding failure, so that the touch screen is disconnected.

The embodiment of the application provides a touch screen resetting method, which is applied to terminal equipment. Acquiring self-tolerant data and mutual-tolerant data of the touch screen based on application programs in the white list; if the self-contained data and the mutual-contained data do not meet the preset consistency condition, determining a touch state corresponding to the touch screen; when the touch state corresponding to the touch screen is a lifted state, resetting the touch screen; therefore, when the self-contained data and the mutual-contained data do not meet the preset consistency condition, the touch screen is not immediately reset, and the touch state corresponding to the touch screen needs to be determined; only when the touch control state is the lifting state, the touch screen is reset; therefore, the phenomenon of touch interruption of the touch screen can be avoided to the greatest extent, the performance and the quality of the touch screen are improved, the user experience is improved, and the purposes of reducing the machine withdrawal of a user and saving the cost can be achieved.

Embodiments of the present application will be described in detail below with reference to the accompanying drawings.

In an embodiment of the present application, referring to fig. 1, a flowchart of a touch screen resetting method provided in an embodiment of the present application is shown. As shown in fig. 1, the method may include:

s101: acquiring self-tolerant data and mutual-tolerant data of the touch screen based on the application programs in the white list;

it should be noted that the touch screen is located in the terminal device. The terminal device may be implemented in various forms, for example, the terminal device may include a mobile phone, a tablet computer, a notebook computer, a palm computer, a Personal Digital Assistant (PDA), a Portable Media Player (PMP), an electronic reader, a vehicle-mounted device, a navigation device, a wearable device, and other devices including a touch screen.

It should also be noted that the touch screen may be a capacitive touch screen. The touch screen works by utilizing the capacitance induction principle of the touch screen, and can judge whether an object contacts the touch screen and report touch information. Here, the object mainly refers to a finger, a stylus, and the like, and the reported touch information includes coordinate information, an event state, and the like, and the event state includes a press (down) state, a lift (up) state, a movement state, and the like.

In addition, the capacitive touch screen mainly comprises a transmitting channel and a receiving channel. The capacitance data of the acquisition transmitting channel and the acquisition receiving channel to the ground are self-capacitance data, and the capacitance data between the acquisition transmitting channel and the acquisition receiving channel are mutual capacitance data. That is, the self-capacitance is the capacitance between the sense mass relative to the circuit's ground, which is always present, although it may be very close or very far from the sense mass. When an excitation signal is applied to the sensing block, an electric field varying with the excitation signal is generated between the sensing block and the ground due to the self-capacitance. The mutual capacitance is the capacitance between one sensing block and another sensing block, when an excitation signal is applied to one sensing block, the excitation signal can be sensed and received on the other sensing block due to the existence of the mutual capacitance, and the magnitude and the phase shift of the received signal are related to the frequency of the excitation signal and the magnitude of the mutual capacitance.

Specifically, the capacitive touch screen generally determines whether the touch state of the object is pressed, lifted or moved according to mutual capacitance data; that is, the mutual capacitance data can be used to determine whether the touch state corresponding to the touch screen is a pressing state, a lifting state or a moving state; in addition, the capacitive touch screen can also realize the judgment of other auxiliary functions, such as a proximity sensing function and the like, through self-capacitance data.

It should be noted that the application mainly refers to a third party application installed in the terminal device, such as a royal glory application. In the running process of the application program, the fingers of the user need to be in contact with the touch screen for a long time, so that the self-compatibility data and the mutual-compatibility data can be obtained by collecting data. Here, the self-compatibility data and the mutual-compatibility data may be acquired in real time or periodically, and the embodiment of the present application is not particularly limited.

Therefore, for the application program in the white list, in the running process of the application program, the self-capacitance data and the mutual capacitance data of the touch screen can be acquired, so that the self-capacitance data and the mutual capacitance data can be obtained, and the subsequent judgment of the reset processing of the touch screen is facilitated.

S102: if the self-capacitance data and the mutual capacitance data do not meet the preset consistency condition, determining a touch state corresponding to the touch screen;

it should be noted that the preset consistency condition is a preset measurement index for determining whether the self-compatibility data and the mutual-compatibility data are consistent. Specifically, based on a preset consistency condition, if the self-contained data is normal and the mutual-contained data does not conform to a preset mutual-contained range corresponding to the mutual-contained data, it may be determined that the self-contained data and the mutual-contained data are inconsistent, that is, the self-contained data and the mutual-contained data do not satisfy the preset consistency condition; correspondingly, if the mutual capacitance data is normal and the self-capacitance data does not meet the preset self-capacitance range corresponding to the self-capacitance data, the self-capacitance data and the mutual capacitance data can also be judged to be inconsistent, namely the self-capacitance data and the mutual capacitance data do not meet the preset consistency condition.

It should be further noted that, when an object is pressed on the touch screen, a touch state corresponding to the touch screen is called a pressed state; when an object is pressed on the touch screen and slides, the touch state corresponding to the touch screen is called as a moving state; when the object leaves the touch screen, the touch state corresponding to the touch screen is called a lifted state; here, the pressed state and the moved state may be referred to as a non-lifted state; in this way, the touch states corresponding to the touch screen may include a lifted state and a non-lifted state.

Therefore, after the self-contained data and the mutual-contained data are obtained, whether the self-contained data and the mutual-contained data meet the preset consistency condition or not can be judged. When the self-contained data and the mutual-contained data meet the preset consistency condition, the fact that the touch screen does not need to be reset is indicated, and the process of the method can be directly ended; when the self-capacitance data and the mutual capacitance data do not meet the preset consistency condition, the fact that the touch screen needs to be reset is indicated, and at the moment, the flow of the method needs to be continuously executed, namely, the touch state corresponding to the touch screen is determined.

S103: and when the touch control state corresponding to the touch screen is the lifting state, resetting the touch screen.

It should be noted that when the self-capacitance data and the mutual capacitance data do not satisfy the preset consistency condition, the determination of the touch state corresponding to the touch screen needs to be continuously executed at this time; and only when the touch control state corresponding to the touch screen is the lifting state, resetting the touch screen. Therefore, even if the self-contained data and the mutual-contained data do not meet the preset consistency condition, if the touch state corresponding to the touch screen is in a non-lifting state, the touch screen still cannot be reset at this time, and therefore error reset processing under abnormal conditions in the existing solution can be avoided.

Specifically, in the current solution, when there is a difference between the self-capacitance data and the mutual capacitance data obtained from the touch screen, that is, the self-capacitance data and the mutual capacitance data do not satisfy the preset consistency condition, the touch screen is immediately reset at this time; however, in some specific scenes (such as a royal glory game, etc.), the finger of the user does not leave the touch screen for a long time, so that the self-capacitance data and the mutual capacitance data are different, and at this time, if the immediate reset processing is performed, the finger may slide on the touch screen to fail, so that the touch screen is disconnected.

In the embodiment of the application, when the touch screen is reset, whether the preset consistency condition is met or not can be judged according to the self-contained data and the mutual-contained data, if the self-contained data and the mutual-contained data do not meet the preset consistency condition, the touch state corresponding to the touch screen is determined at this time, and the touch screen is reset only when the touch state corresponding to the touch screen is determined to be a lifted state. Therefore, according to the touch screen resetting method provided by the embodiment of the application, when the self-capacitance data and the mutual-capacitance data are judged not to meet the preset consistency condition, resetting cannot be directly carried out, and therefore the touch interruption phenomenon of the touch screen can be avoided to the greatest extent.

It should be further noted that, when the touch screen is reset, the preset touch data corresponding to the touch screen may be specifically reset, and meanwhile, the preset touch firmware corresponding to the touch screen may also be reset. That is, in the embodiment of the present application, the reset process may be reset data and/or reset firmware.

In the embodiment of the application, self-tolerant data and mutual-tolerant data of the touch screen are obtained based on application programs in a white list; if the self-contained data and the mutual-contained data do not meet the preset consistency condition, determining a touch state corresponding to the touch screen; when the touch state corresponding to the touch screen is a lifted state, resetting the touch screen; therefore, when the self-contained data and the mutual-contained data do not meet the preset consistency condition, the touch screen is not immediately reset, and the touch state corresponding to the touch screen needs to be determined; only when the touch control state is the lifting state, the touch screen is reset; therefore, the phenomenon of touch interruption of the touch screen can be avoided to the greatest extent, the performance and the quality of the touch screen are improved, the user experience is improved, and the purposes of reducing the machine withdrawal of a user and saving the cost can be achieved.

In some embodiments, before the self-content data and the mutual-content data of the touch screen are acquired, a white list can be established, and then whether the current application program is in the white list or not is judged according to the white list. Therefore, before S101, the method may further include:

s101 a: establishing a white list; wherein, the white list comprises at least one application program with the touch screen resetting method.

It should be noted that the white list is created according to some scenes or application programs that need to use the touch screen resetting method according to the embodiment of the present application; that is, the white list may be a list containing scenes or applications. Specifically, at least one application program with the touch screen resetting method is included in the white list. Further, if an application needs to start the touch screen reset method, the application can also be added into a white list.

In this way, after the white list is established, the white list may be stored in the terminal device. The terminal system corresponding to the terminal device is a large system with a memory and a processor, and the touch screen system corresponding to the touch screen is a small system with a memory and a processor. In this way, the white list may be stored in a memory in the terminal system or in a memory in the touch screen system. Therefore, whether the currently running application program is in the white list or not can be judged according to the obtained white list.

Further, for S101, acquiring self-content data and mutual-content data of the touch screen based on the application programs in the white list may include:

s101 b: determining whether an application is in the white list based on the white list;

s101 c: and when the application program is in the white list, executing the step of acquiring the self-content data and the mutual-content data of the touch screen.

It should be noted that after the white list is obtained, whether the application program is in the white list may be determined. If the application program is not in the white list, the application program does not need to execute the touch screen resetting method of the embodiment of the application, and the flow of the method can be directly ended at this time; if the application program is in the white list, it is described that the application program needs to execute the touch screen resetting method of the embodiment of the application, that is, the step of acquiring the self-compatibility data and the mutual compatibility data of the touch screen is executed.

Further, in some embodiments, a preset reset mode may be set for the application program, and when the application program is in the white list, it is further required to determine whether the application program starts the preset reset mode, so as to determine whether the application program executes the touch screen reset method according to the embodiment of the present application. Thus, for S101c, when the application is in the whitelist, the method may further include:

s101 d: judging whether the application program starts a preset reset mode or not;

s101 e: if the application program starts a preset reset mode, sending a first instruction to a touch screen, wherein the first instruction is used for indicating the touch screen to trigger the preset reset mode;

s101 f: and if the application program exits the preset reset mode, sending a second instruction to the touch screen, wherein the second instruction is used for indicating the touch screen to close the preset reset mode.

It should be noted that after S101d, by determining whether the application program starts the preset reset mode; if the application program starts the preset reset mode, S101e is executed; if the application program exits the preset reset mode, S101f is executed.

It should be further noted that the preset reset mode refers to a touch screen reset method according to an embodiment of the present application. Specifically, in the preset reset mode, whether a preset consistency condition is met or not is judged according to the self-contained data and the mutual-contained data, then the touch state corresponding to the touch screen is determined, and only when the preset consistency condition is judged according to the self-contained data and the mutual-contained data and the touch state corresponding to the touch screen is in a lifted state, the touch screen is reset.

Therefore, whether the application program starts the preset reset mode is judged, if the application program starts the preset reset mode, the fact that the application program needs to execute the touch screen reset method of the embodiment of the application is indicated, at the moment, a first instruction can be sent to the touch screen, and the first instruction is used for indicating the touch screen to trigger the preset reset mode; if the application program exits the preset reset mode, it indicates that the application program does not need to execute the touch screen reset method according to the embodiment of the present application, at this time, a second instruction may be sent to the touch screen, where the second instruction is used to instruct the touch screen to close the preset reset mode.

Thus, for S101, the acquiring self-capacitance data and mutual capacitance data of the touch screen may include:

s101 g: when the application program is in the white list and a preset reset mode is started by the application program, acquiring self-tolerant data and mutual-tolerant data of the touch screen;

s101 h: and acquiring the self-compatibility data and the mutual-compatibility data according to the acquired result.

That is to say, when the application program is in the white list, the application program starts the preset reset mode, and at this time, the self-content data and the mutual-content data can be acquired on the touch screen, so that the self-content data and the mutual-content data are obtained.

Referring to fig. 2, a schematic topological structure diagram of another touch screen reset method provided in the embodiment of the present application is shown. In fig. 2, the topology includes a white list 201, a terminal system 202, and a touch screen system 203, where the white list 201 includes an application, and the application starts a preset reset mode; the terminal system 202 includes an upper system and a lower system, and when the application program starts the preset reset mode, the upper system sends an instruction to the lower system to notify the lower system that the preset reset mode needs to be started, and then the lower system sends an instruction to the touch screen system to notify the touch screen system to trigger the preset reset mode.

It should also be noted that the terminal system is a large system with a memory and a processor, and the touch screen system is a small system with a memory and a processor. The terminal system comprises an upper system and a bottom system which are in a software hierarchical relationship; the underlying system and the touch screen system are in interactive communication via an Inter-Integrated Circuit (I2C) Interface or a Serial Peripheral Interface (SPI) Interface. For example, an address of a register in the touch screen system is used to set whether the touch screen triggers the preset reset mode, and if the address is set to 1, the application program needs to start the preset reset mode; if the address is set to 0, the application program needs to exit the preset reset mode.

In some embodiments, before determining the touch state corresponding to the touch screen, it is further required to determine whether the self-capacitance data and the mutual capacitance data satisfy a preset consistency condition. Wherein, the determining whether the self-contained data and the mutual-contained data satisfy a preset consistency condition may include:

s102 a: acquiring a preset self-capacitance range corresponding to the self-capacitance data and a preset mutual-capacitance range corresponding to the mutual-capacitance data;

s102 b: if the self-contained data does not accord with the preset self-contained range or the mutual-contained data does not accord with the preset mutual-contained range, determining that the self-contained data and the mutual-contained data do not accord with a preset consistency condition;

s102 c: and if the self-capacitance data conforms to the preset self-capacitance range and the mutual capacitance data conforms to the preset mutual capacitance range, determining that the self-capacitance data and the mutual capacitance data meet a preset consistency condition.

It should be noted that before determining whether the self-capacitance data and the mutual capacitance data satisfy the preset consistency condition, a preset self-capacitance range corresponding to the self-capacitance data and a preset mutual capacitance range corresponding to the mutual capacitance data need to be obtained; therefore, whether the self-capacity data and the mutual capacity data meet the preset consistency condition or not is judged according to the preset self-capacity range and the preset mutual capacity range.

Specifically, after the preset self-capacitance range and the preset mutual-capacitance range are obtained, the self-capacitance data and the preset self-capacitance range can be compared to determine whether the self-capacitance data conforms to the preset self-capacitance range, and the mutual-capacitance data and the preset mutual-capacitance range can be compared to determine whether the mutual-capacitance data conforms to the preset mutual-capacitance range; thus, if the self-capacity data do not accord with the preset self-capacity range or the mutual capacity data do not accord with the preset mutual capacity range, the self-capacity data and the mutual capacity data can be determined not to meet the preset consistency condition; if the self-capacitance data conforms to the preset self-capacitance range and the mutual capacitance data conforms to the preset mutual capacitance range, it can be determined that the self-capacitance data and the mutual capacitance data meet the preset consistency condition.

It should be further noted that when the self-capacitance data and the mutual capacitance data do not meet the preset consistency condition, the touch screen reset method in the embodiment of the present application needs to be continuously executed at this time; when the self-contained data and the mutual-contained data meet the preset consistency condition, the touch screen does not need to be reset at this time, and the touch screen resetting method in the embodiment of the application does not need to be executed continuously.

Further, for S102b, if the self-content data does not conform to the preset self-content range or the mutual-content data does not conform to the preset mutual-content range, the determining that the self-content data and the mutual-content data do not satisfy a preset consistency condition may include:

if the self-capacitance data are in accordance with the preset self-capacitance range and the mutual capacitance data are not in accordance with the preset mutual capacitance range, determining that the self-capacitance data and the mutual capacitance data do not meet a preset consistency condition; or,

if the self-capacitance data do not accord with the preset self-capacitance range and the mutual capacitance data accord with the preset mutual capacitance range, determining that the self-capacitance data and the mutual capacitance data do not accord with a preset consistency condition; or,

and if the self-capacitance data do not accord with the preset self-capacitance range and the mutual capacitance data do not accord with the preset mutual capacitance range, determining that the self-capacitance data and the mutual capacitance data do not accord with a preset consistency condition.

That is, for the self-contained data and the mutual-contained data not satisfying the preset consistency condition, there are three cases: the first condition is that the self-capacitance data accords with a preset self-capacitance range, and the mutual capacitance data does not accord with the preset mutual capacitance range; the second condition is that the self-capacitance data does not accord with the preset self-capacitance range, and the mutual capacitance data accords with the preset mutual capacitance range; in the third case, the self-capacitance data does not conform to the preset self-capacitance range, and the mutual-capacitance data does not conform to the preset mutual-capacitance range.

For example, normally, after a finger presses the touch screen, the mutual capacitance data is usually 900, the self-capacitance data is usually 5000, and the unit is the corresponding data after capacitance conversion. Assuming that the preset self-tolerance range is (3000, 5000) and the preset mutual-tolerance range is (500, 900 ]; that is, when the mutual-tolerance data is 900 and the self-tolerance data is less than 3000, it is stated that the mutual-tolerance data conforms to the preset mutual-tolerance range and the self-tolerance data does not conform to the preset self-tolerance range, it can be determined that the self-tolerance data and the mutual-tolerance data do not conform to the preset consistency condition, when the self-tolerance data is 5000 and the mutual-tolerance data is less than 500, it is stated that the self-tolerance data conforms to the preset self-tolerance range and the mutual-tolerance data does not conform to the preset mutual-tolerance range, it can also be determined that the self-tolerance data and the mutual-tolerance data do not conform to the preset consistency condition, besides, when the mutual-tolerance data is less than 500 and the self-tolerance data is less than 3000, it is stated that the mutual-tolerance data does not conform to the preset self-tolerance range, it may also be determined that the self-capacitance data and the mutual-capacitance data are inconsistent, that is, the self-capacitance data and the mutual-capacitance data do not satisfy the preset consistency condition.

In some embodiments, when it is determined that the self-capacitance data and the mutual capacitance data do not satisfy the preset consistency condition, a touch state corresponding to the touch screen, such as a lifted state or a non-lifted state, may also be determined through the mutual capacitance data. Therefore, for S102, when the self-capacitance data and the mutual capacitance data do not satisfy the preset consistency condition, the determining the touch state corresponding to the touch screen may include:

s102 d: acquiring first mutual capacitance data corresponding to a first frame and second mutual capacitance data corresponding to a second frame; wherein the first frame and the second frame are front and rear adjacent frames;

s102 e: calculating a difference value of the first mutual capacitance data and the second mutual capacitance data to obtain a capacitance difference value;

s102 f: if the capacitance difference value is larger than or equal to a preset reporting threshold value, determining that the touch state corresponding to the touch screen is a non-lifting state;

s102 g: and if the capacitance difference value is smaller than a preset reporting threshold value, determining that the touch state corresponding to the touch screen is a lifted state.

It should be noted that after S102e, if the capacitance difference value is greater than or equal to the preset threshold according to the obtained capacitance difference value, S102f is executed; if the capacitance difference value is smaller than the preset threshold value, S102g is executed.

It should be further noted that, when the touch state corresponding to the touch screen is determined according to the mutual capacitance data, the mutual capacitance data of two adjacent frames before and after the touch screen is acquired first, and then the capacitance difference value between the two frames is calculated. Therefore, the touch control state corresponding to the touch screen can be determined by comparing the capacitance difference value with the preset reporting threshold value. Specifically, if the capacitance difference value is greater than or equal to the preset report point threshold value, it can be determined that the touch state is a non-lifted state; if the capacitance difference value is smaller than the preset threshold value, the touch state can be determined to be the lifting state.

For example, assuming that the mutual capacitance data of the first frame is 1000, the mutual capacitance data of the second frame is 900, and the preset threshold is 80, then, since the capacitance difference value between the first frame and the second frame is 1000-; if the mutual capacitance data of the first frame is 900, the mutual capacitance data of the second frame is 1000, and the preset threshold is still 80, then, since the capacitance difference value between the first frame and the second frame is 900 minus 100, the capacitance difference value is smaller than the preset threshold, and at this time, it can be determined that the touch state is the lifted state.

Further, after S102, the method may further include:

and if the touch state corresponding to the touch screen is a non-lifted state, not resetting the touch screen, and continuing to execute the step of determining the touch state corresponding to the touch screen.

It should be noted that after the touch state corresponding to the touch screen is determined, if the touch state is the lifted state, the touch screen needs to be reset, that is, the pre-stored touch data and/or the pre-set touch firmware needs to be reset; correspondingly, if the touch state is a non-lifted state, the touch screen does not need to be reset at this time, that is, the pre-stored touch data and/or the pre-set touch firmware does not need to be reset temporarily, the touch state corresponding to the touch screen is continuously determined, and the touch screen is reset when the touch state is the lifted state.

It should be noted that, in the current solution, when there is a difference between the self-capacitance data and the mutual capacitance data acquired from the touch screen, that is, the self-capacitance data and the mutual capacitance data do not satisfy the preset consistency condition, at this time, the touch screen is immediately reset, that is, the firmware is immediately reset, so that the lift-up event is released in advance; thereby causing a touch interruption phenomenon of the touch screen. In the embodiment of the application, when the self-volume data and the mutual-volume data are judged not to meet the preset consistency condition, the reset processing cannot be directly performed, at this time, the touch state corresponding to the touch screen needs to be determined, and only when the touch state corresponding to the touch screen is determined to be the lifted state, the reset processing is performed on the touch screen; therefore, the touch screen can avoid the touch interruption phenomenon to the maximum extent.

The embodiment provides a touch screen resetting method, which is based on an application program in a white list, and self-tolerant data and mutual-tolerant data of a touch screen are obtained; if the self-contained data and the mutual-contained data do not meet the preset consistency condition, determining a touch state corresponding to the touch screen; when the touch state corresponding to the touch screen is a lifted state, resetting the touch screen; therefore, when the self-contained data and the mutual-contained data do not meet the preset consistency condition, the touch screen is not immediately reset, and the touch state corresponding to the touch screen needs to be determined; only when the touch control state is the lifting state, the touch screen is reset; therefore, the touch screen can be prevented from being broken to the greatest extent, the performance and the quality of the touch screen are improved, the game experience of a user is improved, and the purposes of reducing the machine withdrawal of the user and saving the cost can be achieved.

In another embodiment of the present application, referring to fig. 3, a detailed flowchart of a touch screen resetting method provided in an embodiment of the present application is shown. As shown in fig. 3, the detailed flow may include:

s301: establishing a white list;

it should be noted that the white list is created according to some scenes or application programs that need to use the touch screen resetting method according to the embodiment of the present application; that is, the white list may be a list containing scenes or applications. For example, a royal glory application requires the use of the touch screen reset method, and the royal glory application is included in the whitelist.

S302: judging whether the current application program is in the white list or not;

s303: if the application program is not in the white list, exiting the process;

s304: if the application program is in the white list, judging whether the application program starts a preset reset mode or not;

it should be noted that, after S302, by determining whether the current application program is in the white list, if the current application program is not in the white list, S303 is executed; if the application is in the white list, S304 is performed.

That is, after the white list is obtained, it may be determined whether the application is within the white list. If the application program is not in the white list, the application program does not need to execute the touch screen resetting method of the embodiment of the application, and the process can be directly ended at this time; if the application program is in the white list, it is indicated that the application program needs to execute the touch screen reset method of the embodiment of the application, that is, the step of judging whether the application program starts the preset reset mode is continuously executed.

S305: if the application program starts the preset reset mode, the application program is in a starting stage, an upper layer system in the terminal system informs a bottom layer system to start the preset reset mode, and the bottom layer system sends a first instruction to a touch screen system to indicate the touch screen to trigger the preset reset mode;

s306: if the application program exits the preset reset mode, the application program is in an exit stage, an upper layer system in the terminal system informs a bottom layer system to close the preset reset mode, and the bottom layer system sends a second instruction to the touch screen system to instruct the touch screen to close the preset reset mode;

it should be noted that after S304, by determining whether the application program starts the preset reset mode, if the application program starts the preset reset mode, S305 is executed; if the application program exits the preset reset mode, S306 is performed. It is further noted that after S305, execution continues with S307-S310; after S306, execution continues with S311.

Specifically, if the application program starts a preset reset mode, at the starting stage, the upper layer system informs the bottom layer system to start the preset reset mode, and then the bottom layer system sets a touch screen system to trigger the preset reset mode; if the application program exits the preset reset mode, at the exit stage, the upper layer system informs the bottom layer system to close the preset reset mode, and then the bottom layer system sets the touch screen system to close the preset reset mode.

It should also be noted that the terminal system is a large system with a memory and a processor, and the touch screen system is a small system with a memory and a processor. The terminal system is generally divided into two software hierarchical relationships, namely an upper system and a bottom system. The underlying system may set registers within the touchscreen system through the I2C interface or the SPI interface. For example, an address of a register in the touch screen system is used to set whether the touch screen triggers the preset reset mode, and if the address is set to 1, the application program needs to start the preset reset mode; if the address is set to 0, the application program needs to exit the preset reset mode.

S307: acquiring self-capacitance data and mutual capacitance data of the touch screen by collection in the running process of the application program;

s308: when the self-contained data and the mutual-contained data do not meet the preset consistency condition, judging whether the touch state corresponding to the touch screen is a lifted state or not;

s309: if the touch state corresponding to the touch screen is a lifted state, resetting the touch screen;

s310: if the touch state corresponding to the touch screen is a non-lifting state, resetting the touch screen is not carried out, and whether the touch state corresponding to the touch screen is a lifting state or not is continuously judged;

it should be noted that, the capacitance data collected to ground through the transmitting channel and the receiving channel during self-capacitance data, and the capacitance data between the transmitting channel and the receiving channel during mutual capacitance data are collected. The detection of the inconsistency between the self-capacitance data and the mutual capacitance data is an error handling mechanism for judging whether the current touch screen is abnormal or not by the capacitive touch screen. The abnormal condition of inconsistency of the self-tolerant data and the mutual-tolerant data comprises the following steps: when the mutual capacitance data is normal (namely the mutual capacitance data conforms to the preset mutual capacitance range) and the self-capacitance data is abnormal (namely the self-capacitance data does not conform to the preset self-capacitance range), the self-capacitance data is inconsistent with the mutual capacitance data; when the self-capacitance data is normal (i.e. the self-capacitance data conforms to the preset self-capacitance range) and the mutual capacitance data is abnormal (i.e. the mutual capacitance data does not conform to the preset mutual capacitance range), the self-capacitance data and the mutual capacitance data are inconsistent.

Further, when it is determined that the self-volume data and the mutual-volume data do not meet the preset consistency condition, whether a touch state corresponding to the touch screen is a lifted state or not needs to be judged; if the touch state is the lifted state, executing S309, namely performing reset processing on the touch screen, specifically, resetting data and firmware; if the touch state is the non-lifted state, executing S310, that is, not resetting the touch screen, specifically not resetting data and firmware, and at this time, continuously determining whether the touch state corresponding to the touch screen is the lifted state, that is, circularly executing S308; and only when the touch control state is the lifting state, the touch screen is reset.

In the embodiment of the application, the reset data and the reset firmware mainly refer to whether the capacitive touch screen resets the firmware again or not, and the current data is calibrated to be normal data.

S311: and when the self-contained data and the mutual-contained data do not meet the preset consistency condition, immediately resetting the touch screen.

It should be noted that, if the application exits from the preset reset mode, at this time, in the exit stage, the upper system notifies the lower system to close the preset reset mode, and then the lower system sets the touch screen system to close the preset reset mode. In this case, the default mechanism of the touch screen system is restored without turning on the preset reset mode. In this way, after the touch screen system recovers the default mechanism, if the self-contained data and the mutual-contained data do not meet the preset consistency condition, the touch screen is immediately reset, namely, the data and the firmware are immediately reset.

In summary, in the embodiment of the present application, when an abnormal condition occurs in the touch screen, where the self-capacitance data and the mutual capacitance data are inconsistent, the touch screen is not directly reset, and a touch state corresponding to the touch screen needs to be further determined; only when the touch state corresponding to the touch screen is determined to be the lifting state, the touch screen is reset, and therefore the touch interruption phenomenon of the touch screen can be avoided to the greatest extent.

Through the embodiment, the specific implementation of the embodiment is elaborated, and it can be seen that through the technical scheme of the embodiment, when the self-capacitance data and the mutual capacitance data do not meet the preset consistency condition, the touch screen is not immediately reset, and at this time, the touch state corresponding to the touch screen needs to be determined; only when the touch control state is the lifting state, the touch screen is reset; therefore, the touch screen can be prevented from being broken to the greatest extent, the performance and the quality of the touch screen are improved, the game experience of a user is improved, and the purposes of reducing the machine withdrawal of the user and saving the cost can be achieved.
