The terminal in the embodiment of the present invention may be a terminal having an operating system. The operating system may be an Android (Android) operating system, an ios operating system, or other possible operating systems, and embodiments of the present invention are not limited in particular.
The following describes a software environment to which the control method of the touch screen provided by the embodiment of the present invention is applied, by taking an android operating system as an example.
Fig. 1 is a schematic diagram of an architecture of a possible android operating system according to an embodiment of the present invention, in fig. 1, the architecture of the android operating system includes 4 layers, which are an application layer, an application framework layer, a system runtime layer, and a kernel layer (specifically, L inux kernel layer).
The application program layer comprises various application programs (including system application programs and third-party application programs) in an android operating system.
The application framework layer is a framework of the application, and a developer can develop some applications based on the application framework layer under the condition of complying with the development principle of the framework of the application.
The system runtime layer includes libraries (also called system libraries) and android operating system runtime environments. The library mainly provides various resources required by the android operating system. The android operating system running environment is used for providing a software environment for the android operating system.
The kernel layer is an operating system layer of the android operating system and belongs to the lowest layer of a software layer of the android operating system, and the kernel layer provides core system services and hardware-related drivers for the android operating system based on L inux kernels.
Taking an android operating system as an example, in the embodiment of the present invention, a developer may develop a software program for implementing the control method of the touch screen provided in the embodiment of the present invention based on the system architecture of the android operating system shown in fig. 1, so that the control method of the touch screen may run based on the android operating system shown in fig. 1. Namely, the processor or the terminal can implement the control method of the touch screen provided by the embodiment of the invention by running the software program in the android operating system.
The first embodiment is as follows:
a control method of a touch screen according to an embodiment of the present invention is described below with reference to fig. 2, where fig. 2 is a schematic flow chart of the control method of the touch screen according to the embodiment of the present invention, and as shown in fig. 2, the method includes the following steps:
s201, under the condition that the terminal is in a screen locking state, the terminal receives touch operation of a user on a fingerprint identification area of a touch screen.
In an embodiment of the present invention, the touch operation is a pressing operation of a user on a fingerprint identification area of the touch screen.
S202, if the touch operation indicates that the terminal unlocks the screen, the terminal sets a response threshold of a touch screen of the terminal as a first threshold.
In the embodiment of the invention, when the terminal determines that the touch operation is an operation of inputting a fingerprint on the fingerprint identification area by a user, the touch operation is determined to be used for indicating the terminal to unlock the screen.
Optionally, in the embodiment of the present invention, when the response threshold of the touch screen of the terminal is set as the first threshold, the terminal may select to increase the response threshold of the full screen, or may select to increase only the response threshold of the fingerprint identification area of the touch screen, that is, when it is determined that the touch operation is used to instruct the terminal to unlock the screen, the terminal only increases only the response threshold of the fingerprint identification area to the second threshold, and the response thresholds of other areas except the fingerprint identification area in the touch screen are still the first threshold.
And S203, under the condition that the touch operation is finished, the terminal sets the response threshold value as a second threshold value.
Wherein, the first threshold is larger than the second threshold.
In the embodiment of the present invention, when the touch operation is ended, or after the finger of the user leaves the fingerprint identification area, the terminal may restore the response threshold of the touch operation, that is, the response threshold is changed from the first threshold to the second threshold.
In addition, due to the influence of factors such as aging of the touch screen or accidental scratching, the terminal detects touch operation in the fingerprint identification area for a long time, so that the terminal cannot recover the response threshold value to influence the normal use of the user. At this time, the embodiment of the present invention introduces a timeout mechanism to force recovery of the response threshold, so as to solve the problem that the response threshold cannot be recovered in the fingerprint identification area due to factors such as aging of the touch screen or accidental scratching.
Optionally, in this embodiment of the present invention, S202 includes the following steps:
s202a, when the touch duration of the touch operation is greater than or equal to a first predetermined duration, the terminal sets the response threshold as a second threshold. At this time, no matter whether the user finishes the touch operation, the terminal defaults that the touch operation is finished, and the terminal restores the response threshold to the second threshold.
In the embodiment of the present invention, when the terminal executes S202, the following two possible implementation manners may be implemented.
A first possible implementation: after the terminal determines that the touch operation is used for indicating the terminal to unlock the screen (namely, after the terminal identifies the user fingerprint), the terminal directly sets the response threshold of the touch screen as a first threshold.
A second possible implementation: when the terminal determines that the touch operation is used for indicating the terminal to unlock the screen, after the screen of the terminal is unlocked, whether the response threshold of the touch screen is set as the first threshold can be determined by judging whether the touch operation is detected (namely whether the finger of the user leaves the touch screen). Specifically, if the touch operation is detected, the response threshold of the touch screen is set as the first threshold, and if the touch operation is not detected, no processing is performed.
Exemplarily, in the embodiment of the present invention, the step S202 specifically includes the following steps:
s202b1, if the fingerprint data of the touch operation indicate that the terminal unlocks the screen, the terminal acquires the flatness value of the fingerprint identification area.
In the embodiment of the invention, the terminal determines whether a touch operation is detected in the fingerprint identification area (i.e. whether the finger of the user leaves the touch screen) by judging whether the touch screen event is triggered in the fingerprint identification area when the terminal screen is unlocked.
S202b2, if the terminal determines that the flatness value is greater than or equal to the third threshold, the terminal sets the response threshold as the first threshold.
In an embodiment of the present invention, the flatness value of the fingerprint identification area is used to characterize the flatness of the fingerprint identification area. The flatness value of the fingerprint identification area is the accumulated value of the flatness values of all the touch units in the fingerprint identification area; the flatness value of the touch unit is an absolute difference value between the capacitance value of the touch unit and the capacitance value of the touch unit adjacent to the touch unit. For example, the touch unit adjacent to the touch unit may be a previous touch unit or a next touch unit of the touch unit, or an upper touch unit or a lower touch unit, which is not limited in the present invention.
In an ideal state, when a touch event does not occur in the touch screen, capacitance values of all touch units in the touch screen are the same, at this time, a flatness value of the touch screen is 0, and when a touch event occurs in the touch screen, a flatness value of an area where the touch event occurs in the touch screen is greater than 0, generally, if the flatness value of a certain area in the touch screen is smaller, the area is flatter. It should be noted that, due to different usage frequencies of the touch units in the touch screen, the sensitivity levels of the different touch units are different, so that capacitance values of all touch units in the touch screen when no touch screen event occurs in the touch screen have a certain slight difference, which are not completely the same. Therefore, the embodiment of the present invention sets a third threshold, when the flatness value of the fingerprint identification area is greater than or equal to the third threshold, the fingerprint identification area is considered to be uneven, that is, there is a touch operation on the fingerprint identification area, otherwise, when the flatness value of the fingerprint identification area is less than the third threshold, the fingerprint identification area is considered to be flat, that is, there is no touch operation on the fingerprint identification area.
In one example, toFor example, when the touch screen is powered on, the terminal obtains capacitance values of all touch units in the fingerprint identification area of the touch screen, and then obtains a capacitance matrix S according to specific arrangement positions of all touch units in the fingerprint identification area, wherein an element R in the matrix S isijThe capacitance value of the touch unit in the ith row and the jth column is represented.
If the matrix S is taken as an example to calculate the flatness value of the fingerprint identification area, the capacitance value of each element in each column is subtracted from the capacitance value of the next element by taking the absolute value as a unit, and then all the absolute values are accumulated to obtain a column absolute value sum, and if the capacitance value difference of all the elements in a certain matrix S is small, the calculated absolute value sum is small (ideally, if the column data is the same, the column absolute value sum is 0). Of course, the capacitance value of each element in each row may be subtracted from the capacitance value of the next element, and then the absolute value is obtained, and then all the absolute values are accumulated to obtain a row absolute value sum. Finally, the column absolute value sum or the row absolute value sum may be used as the flatness value of the current fingerprint identification area, or the column absolute value sum and the row absolute value sum may be added to obtain a total absolute value sum, and the total absolute value sum is used as the flatness value of the current fingerprint identification area. It should be noted that the above-mentioned subtraction of the capacitance value of each element in each column/row and the capacitance value of the next element to obtain the absolute value is merely an example, and in actual calculation, the above-mentioned subtraction may also be performed with the capacitance value of the previous or next or previous element.
Here, the matrix S is described in tables 1 and 2, and it should be noted that the real matrix S has higher-level dimensions, and the following tables 1 and 2 are merely examples.

TABLE 2
For example, table 1 is used to show capacitance values of some touch units in the fingerprint identification area when no finger of the user touches the fingerprint identification area. The above table 2 is used to indicate capacitance values of some touch units in the fingerprint identification area when a user touches the fingerprint identification area. Comparing table 1 and table 2, it can be seen that the capacitance values of the touch units are different if the touch unit is touched by a finger of a user.

TABLE 4
Illustratively, the capacitance value of each element in each column in table 1 is subtracted from the capacitance value of an adjacent element in a subsequent column to obtain table 3, and the capacitance value of each element in each column in table 2 is subtracted from the capacitance value of an adjacent element in a subsequent column to obtain table 4. Based on the above tables 1 to 4, it can be seen that, if the touch unit has no finger touch by the user, the influence on the flatness value of the fingerprint identification area is very large, and if the finger of the user corresponding to table 2 leaves, the data in table 2 will be restored to table 1, so that the flatness value will change from a larger value to a smaller value, and based on the characteristics of the flatness value, we can determine whether the finger has left the screen.
In the embodiment of the invention, when the terminal screen is unlocked, if it is detected that the finger of the user does not leave the fingerprint identification area, that is, when a touch operation exists on the fingerprint identification area, the response threshold of the touch screen is temporarily increased, that is, the response threshold of the touch screen is changed from the second threshold to the first threshold, so that a point error report of the fingerprint identification area (that is, a touch error event occurs in the fingerprint identification area) caused by slight movement of the finger of the user after the touch screen is powered on is avoided. Certainly, when the terminal screen is unlocked, if the user finger is not detected in the fingerprint identification area, no additional processing is needed.
Optionally, in an embodiment of the present invention, the touch operation includes fingerprint data and touch data.
For example, the instructing the terminal to unlock the screen by the touch operation in S202 includes: the fingerprint data of the touch operation indicates the terminal to unlock the screen. Based on this, after S202, the method further includes the steps of:
s202c1, if the touch data corresponding to the touch operation on the first touch unit of the fingerprint identification area is greater than or equal to the first threshold, the terminal responds to the touch instruction corresponding to the first touch data on the first touch unit.
S202c2, if the touch data is smaller than the first threshold, the terminal does not respond to the touch command corresponding to the first touch data on the first touch unit.
In an embodiment of the invention, the first touch data may include: when the user triggers the touch operation on the fingerprint identification area, the absolute difference value between the capacitance value of the first touch unit and the initial capacitance value of the first touch unit.
In an embodiment of the invention, the first touch unit may be any touch unit in the fingerprint identification area. For example, the initial capacitance value of the touch unit may be an initial capacitance value of the touch unit when the touch screen of the terminal is powered on, or an initial capacitance value of the touch unit when the fingerprint identification area is not touched by a finger of a user.
For example, taking table 1 and table 2 as an example, subtracting each data in table 1 from the corresponding data in table 2 to obtain table 3, where table 5 is the touch data corresponding to each element in table 2.

TABLE 5
For example, if the response threshold is increased from 500 (i.e., the second threshold) to 1000 (i.e., the first threshold), the terminal will only respond to the data with an absolute difference greater than 1000 in table 5.
According to the control method of the touch screen, the occurrence of the false touch event caused by slight movement of the finger of the user is avoided by temporarily improving the response threshold of the touch screen in the fingerprint unlocking process, so that the user can have better user experience in the fingerprint unlocking process.
