Detailed Description
Reference will now be made in detail to embodiments of the present invention, examples of which are illustrated in the accompanying drawings, wherein like or similar reference numerals refer to the same or similar elements or elements having the same or similar function throughout. The embodiments described below with reference to the drawings are illustrative and intended to be illustrative of the invention and are not to be construed as limiting the invention.
A method, an apparatus, an electronic device, and a computer-readable storage medium for compensating a dead zone of a touch screen according to embodiments of the present invention are described below with reference to the accompanying drawings.
FIG. 1 is a flow chart of a method of compensating for a dead zone of a touch screen according to one embodiment of the invention. It should be noted that the method for compensating the dead zone of the touch screen according to the embodiment of the present invention may be applied to the apparatus for compensating the dead zone of the touch screen according to the embodiment of the present invention, and the apparatus for compensating the dead zone of the touch screen may be configured on the electronic device according to the embodiment of the present invention. The electronic device may be a mobile terminal, for example, the mobile terminal may be a hardware device with various operating systems, such as a mobile phone, a tablet computer, and a personal digital assistant.
As shown in fig. 1, the method for compensating the dead zone of the touch screen may include:
s110, when a touch operation on the touch screen is monitored, touch data of a touch area corresponding to the touch operation are obtained, wherein the touch data comprise position coordinates of a plurality of touched touch units and capacitance values of the plurality of touched touch units.
It should be noted that, in the embodiment of the present invention, the touch screen may be a capacitive touch screen, and the capacitive touch screen may include a plurality of touch units. Therefore, whether touch operation exists on the touch screen can be judged by detecting whether the capacitance value of the touch unit changes. When the capacitance values of a plurality of touch units in the capacitive touch screen are judged to be changed, the touch operation on the touch screen can be monitored, and at the moment, the touch data of a touch area corresponding to the touch operation can be acquired.
And S120, judging whether a dead zone exists in the touch area according to the touch data, wherein the dead zone is used for indicating that the touch screen touches a damaged area without functions.
As an example, it may be determined whether there is a touch unit with unchanged capacitance value in the touch area according to the touch data, and if not, it is determined that there is no dead zone in the touch area; and if so, judging that the dead zone exists in the touch area.
That is to say, it can be determined whether the capacitance value of the touched touch unit in the touch area has not changed according to the touch data, if so, it can be determined that a dead zone exists in the touch area, otherwise, it can be determined that no dead zone exists in the touch area. The dead zone is understood to mean that when a user touches the area, the capacitance value of the area does not change, so that the system of the electronic device cannot feel the touch operation of the user through the area.
And S130, if the touch area has the dead zone, performing dead zone compensation according to the touch data to simulate the report point position, and outputting the report point position obtained by simulation.
Optionally, when it is determined that the touch area has the dead zone, the capacitance variation of the touch unit at the dead zone position may be simulated according to the capacitance variation of the touched touch unit around the dead zone in the touch data, so as to obtain a real touch position, and the touch position obtained through the simulation is used as a touch point position to perform touch point output.
As an example, as shown in fig. 2, the specific implementation of performing dead zone compensation according to touch data to simulate a report point position may include:
s210, determining the touched touch control unit with unchanged capacitance value according to the touch data; that is, it can be determined from the touch data which touched touch units have unchanged capacitance values.
S220, determining dead zones and non-dead zones in the touch area according to the touched touch unit with unchanged capacitance value;
optionally, a region of the touch region, where the capacitance value is unchanged, formed by the touched touch unit is used as a dead zone, and other regions of the touch region are used as non-dead zones.
S230, determining the shape of the dead zone;
that is, the shape of the dead zone may be determined according to the number of touched touch units in the dead zone and the distribution in the touch area. For example, the dead zone may be formed by a touched touch unit with unchanged capacitance; for another example, the dead zone is a row or a column of a plurality of touched touch units with unchanged capacitance values.
S240, simulating a report point position in the touch area according to the shape of the dead zone and the capacitance value of the touched touch unit in the non-dead zone.
Alternatively, the true touch position may be determined from the touch area according to the shape of the dead zone and the capacitance of the touched touch unit in the non-dead zone. In the embodiment of the present invention, the dead zone breakpoint compensation method may be different according to the shape of the dead zone. Referring to fig. 3 and 5 below, two different examples will be given to show how the location of a touch point in the touch area can be modeled according to the shape of a dead zone and the capacitance value of the touched touch unit in the non-dead zone.
As an example, as shown in fig. 3, the simulating the touch location in the touch area according to the shape of the dead zone and the capacitance value of the touched touch unit in the non-dead zone may include:
s2411, when the dead zone is formed by a touched touch unit with unchanged capacitance value, acquiring the maximum value and the second maximum value of the capacitance in the non-dead zone;
it can be understood that when a touch operation is performed on the touch screen, the capacitance value of the touch unit on the touch screen changes, and the touch screen IC can determine the specific position of the touch according to the magnitude of the change in the capacitance value of the touch unit, for example, the position of the touch unit with the largest change in capacitance value is generally taken as a touch point position, as shown in fig. 4(a), 20 × 18 touch screen data is obtained, the position where the capacitance value changes in the touch screen data is caused by the touch operation, and it can be known from the figure that the position (13, 8) of the touch unit corresponding to the capacitance value "399" is the actual touch position (i.e., the touch point position). However, when a touch screen fails and a certain touch unit becomes a dead zone, a specific touch position cannot be detected, and a correct touch position cannot be identified.
In this step, when the dead zone is formed by a touched touch unit with unchanged capacitance value, the maximum capacitance value and the second maximum capacitance value in the non-dead zone may be obtained first. For example, as shown in fig. 4(b) and 4(c), the touch unit with a capacitance value of 0 in the touch area in the figure is the dead zone (e.g., the circle area in the figure), and at this time, the maximum capacitance value and the second maximum capacitance value of the non-dead zone in the touch area may be obtained. For example, as shown in fig. 4(b), the maximum value and the second maximum value of the capacitance of the non-dead zone are "399" and "381", respectively, and as shown in fig. 4(c), the maximum value and the second maximum value of the capacitance of the non-dead zone are "381" and "318", respectively.
S2412, judging whether the touched touch control unit corresponding to the maximum capacitance value and the touched touch control unit corresponding to the second maximum capacitance value are in the same row or the same column;
s2413, if so, taking the position coordinate of the touched touch unit corresponding to the maximum capacitance value as a report point position;
that is, when the touched touch unit corresponding to the maximum capacitance value and the touched touch unit corresponding to the second maximum capacitance value are in the same row or the same column, it can be considered that the dead zone is not the center of the touch area.
For example, as shown in fig. 4(a), when there is a touch operation on the touch screen, in the capacitance variation data of the normal touch unit, the capacitance variation at the center point (e.g., the position of coordinates (13, 8)) is the largest, and the peripheral capacitance variation decreases sequentially outward. When a touch screen fails to work and a certain touch unit becomes a dead zone, as shown in fig. 4(b), the touch unit at coordinates (12, 8) is a dead zone, and at this time, the touched touch unit corresponding to the maximum capacitance value ("399") in the non-dead zone and the touched touch unit corresponding to the second maximum capacitance value ("381") are in the same column, and at this time, the position of the touched touch unit corresponding to the maximum capacitance value may be a real touch position, and the position coordinate is taken as a touch point position.
S2414, if not, taking the position coordinates of the touched touch control unit corresponding to the dead zone as the report point position.
That is, when the touched touch unit corresponding to the maximum capacitance value and the touched touch unit corresponding to the second maximum capacitance value are not in the same row and/or the same column, the position coordinate of the touched touch unit corresponding to the dead zone can be used as the report point position.
For example, as shown in fig. 4(c), the touch unit at coordinates (13, 8) is a dead zone, and at this time, the touched touch unit corresponding to the maximum capacitance value ("381") in the non-dead zone and the touched touch unit corresponding to the second largest capacitance value ("318") are in different columns and different rows, and at this time, the position of the touched touch unit corresponding to the dead zone can be taken as the real touch position, and the touch position coordinate can be taken as the touch point position.
Therefore, the real touch point position in the touch area is determined by judging whether the touched touch unit corresponding to the maximum capacitance value in the non-dead zone and the touched touch unit corresponding to the second maximum capacitance value are in the same row or the same column, so that even if the dead zone appears on the touch screen, the touch screen can output the report point on the dead zone to a system of the electronic equipment, the touch operation acting on the dead zone can not be influenced, and the touch function of the touch screen is ensured.
As another example, as shown in fig. 5, the specific implementation of simulating the touch location in the touch area according to the shape of the dead zone and the capacitance value of the touched touch unit in the non-dead zone may include:
s2421, when the dead zone is a row or a column formed by a plurality of touched touch units with unchanged capacitance values, acquiring the maximum capacitance value and the second maximum capacitance value in the non-dead zone;
for example, as shown in fig. 6(a) and 6(b), the dead zone is a column composed of a plurality of touch-touched units with unchanged capacitance values, and as shown in fig. 7(a) and 7(b), the dead zone is a row composed of a plurality of touch-touched units with unchanged capacitance values. At this time, the dead zone divides the touch area into three parts, namely: a dead zone and two non-dead zones, where the maximum and next maximum values of capacitance in these non-dead zones can be obtained. For example, as shown in fig. 6(a), the maximum value of capacitance and the second maximum value of capacitance in the non-dead zone are "399" and "381" in this order; as shown in fig. 6(b), the capacitance maximum value and the capacitance next largest value in the non-dead zone are "381" and "281" in this order; as shown in fig. 7(a), the maximum value of capacitance and the second maximum value of capacitance in the dead zone are "399" and "318" in this order; as shown in fig. 7(b), the capacitance maximum value and the capacitance next largest value in the dead zone are "381" and "272" in this order.
S2422, judging whether the touched touch unit corresponding to the maximum capacitance value and the touched touch unit corresponding to the second maximum capacitance value are in the same non-dead zone;
s2423, if yes, taking the position coordinate of the touched touch unit corresponding to the maximum capacitance value as a report point position;
for example, taking the dead zone as a row of touched touch units with unchanged capacitance values as an example, as shown in fig. 6(a), it can be determined that the touched touch unit corresponding to the maximum capacitance value and the touched touch unit corresponding to the second largest capacitance value are in the same non-dead zone, and at this time, the position coordinate of the touched touch unit corresponding to the maximum capacitance value can be used as the touch point position, that is, the position coordinate (13, 8) of the touch unit corresponding to the capacitance value "399" can be used as the touch point position.
For another example, taking the dead zone as a row composed of a plurality of touched touch units with unchanged capacitance values as an example, as shown in fig. 7(a), it can be determined that the touched touch unit corresponding to the maximum capacitance value and the touched touch unit corresponding to the second largest capacitance value are in the same non-dead zone, and at this time, the position coordinate of the touched touch unit corresponding to the maximum capacitance value can be used as the touch point position, that is, the position coordinate (13, 8) of the touch unit corresponding to the capacitance value "399" can be used as the touch point position.
And S2424, if not, determining the report point position in the touch area according to the touched touch unit corresponding to the maximum capacitance value and the touched touch unit corresponding to the second maximum capacitance value.
Optionally, when it is determined that the touched touch unit corresponding to the maximum capacitance value and the touched touch unit corresponding to the second maximum capacitance value are not in the same non-dead zone, at this time, the touched touch unit corresponding to the maximum capacitance value and the touched touch unit corresponding to the second maximum capacitance value may be used, and a position coordinate of the touch unit between the touched touch unit corresponding to the maximum capacitance value and the touched touch unit corresponding to the second maximum capacitance value may be used as a touch point position of the touch area.
For example, taking the dead zone as a row of touched touch units with unchanged capacitance values as an example, as shown in fig. 6(b), the touched touch unit corresponding to the maximum capacitance value and the touched touch unit corresponding to the second largest capacitance value can be determined to be in different non-dead zones, and in this case, the position coordinates (13, 8) of the touch units between the touched touch unit corresponding to the maximum capacitance value and the touched touch unit corresponding to the second largest capacitance value can be used as the touch point position.
For another example, taking the dead zone as a row composed of a plurality of touched touch units with unchanged capacitance values as an example, as shown in fig. 7(b), it can be determined that the touched touch unit corresponding to the maximum capacitance value and the touched touch unit corresponding to the next largest capacitance value are in different non-dead zones, and at this time, the position coordinates (13, 8) of the touch units between the touched touch unit corresponding to the maximum capacitance value and the touched touch unit corresponding to the next largest capacitance value can be taken as the touch point position.
Therefore, the real touch point position in the touch area is determined by judging whether the touched touch unit corresponding to the maximum capacitance value and the touched touch unit corresponding to the second maximum capacitance value in the touch data are in the same non-dead zone, so that even if a certain column or a certain row on the touch screen becomes a dead zone, the touch screen can output a report point on the dead zone to a system of the electronic equipment, the touch operation acting on the dead zone can not be influenced, and the touch function of the touch screen is ensured.
And S140, if the touch area does not have the dead zone, determining a target report point position from the touch area according to the touch data, and reporting the target report point position for outputting.
As an example, the touched touch unit with the largest capacitance value may be obtained from the touch data, and the position coordinate of the touched touch unit with the largest capacitance value may be determined as the target report point position. That is, when there is no dead zone in the touch area, it is considered that the capacitance value in the touch area changes normally, and in this case, the position coordinates of the touch unit corresponding to the maximum value of the capacitance in the touch area may be output as the hit point position of the touch area.
According to the compensation method for the dead zone of the touch screen, when the touch operation on the touch screen is monitored, touch data of a touch area corresponding to the touch operation are obtained, whether the dead zone exists in the touch area is judged according to the touch data, if yes, the dead zone compensation is carried out according to the touch data, a report point position is simulated, report point output is carried out on the report point position obtained through simulation, and if not, a target report point position is determined from the touch area according to the touch data, and the report point output is carried out on the target report point position. After the touch screen has the dead zone, the dead zone report point can be compensated according to the capacitance change of the touch units around the dead zone, the real touch position in the touch zone can be determined and output as the report point, and thus, the touch operation acting on the dead zone can be received by the system, the system can make corresponding response according to the touch operation, the touch function of the touch screen can be guaranteed without replacing the touch screen, the problem that the expense of a user and the use cost of electronic equipment are increased due to the replacement of the touch screen is avoided, and the use experience of the user is greatly improved.
Corresponding to the methods for compensating the dead zone of the touch screen provided in the foregoing embodiments, an embodiment of the present invention further provides a device for compensating the dead zone of the touch screen, and since the device for compensating the dead zone of the touch screen provided in the embodiment of the present invention corresponds to the methods for compensating the dead zone of the touch screen provided in the foregoing embodiments, the embodiments of the method for compensating the dead zone of the touch screen are also applicable to the device for compensating the dead zone of the touch screen provided in the present embodiment, and will not be described in detail in the present embodiment. Fig. 8 is a schematic structural diagram of an apparatus for compensating a dead zone of a touch screen according to an embodiment of the present invention. It should be noted that the compensation apparatus for the dead zone of the touch screen according to the embodiment of the present invention may be configured on the electronic device according to the embodiment of the present invention. The electronic device may be a mobile terminal, for example, the mobile terminal may be a hardware device with various operating systems, such as a mobile phone, a tablet computer, and a personal digital assistant. In addition, the touch screen may be a capacitive touch screen, which may include a plurality of touch units.
As shown in fig. 8, the apparatus 800 for compensating the dead zone of the touch screen may include: the system comprises an acquisition module 810, a determination module 820, a dead zone compensation module 830, a report output module 840, and a determination module 850.
Specifically, the obtaining module 810 may be configured to obtain touch data of a touch area corresponding to a touch operation when the touch operation on the touch screen is monitored, where the touch data includes position coordinates of a plurality of touched touch units and capacitance values of the plurality of touched touch units.
The judging module 820 is configured to judge whether a dead zone exists in the touch area according to the touch data, where the dead zone is used to indicate that the touch screen touches a damaged area without functions. As an example, the determining module 820 may determine whether there is a touch unit with unchanged capacitance value in the touch area according to the touch data, and if not, determine that there is no dead zone in the touch area; and if so, judging that the dead zone exists in the touch area.
The dead zone compensation module 830 is configured to perform dead zone compensation according to the touch data when a dead zone exists in the touch area, so as to simulate a touch point position. As an example, as shown in fig. 9, the dead zone compensation module 830 may include: a first determining unit 831, a second determining unit 832, a third determining unit 833 and a hit simulating unit 834. The first determining unit 831 is configured to determine, according to the touch data, a touched touch unit whose capacitance value is unchanged; the second determining unit 832 is configured to determine a dead zone and a non-dead zone in the touch area according to the touched touch unit with unchanged capacitance value; the third determination unit 833 is used to determine the shape of the dead zone; the touch point simulation unit 834 is configured to simulate a touch point position in the touch area according to the shape of the dead zone and the capacitance of the touched touch unit in the non-dead zone.
In the embodiment of the present invention, the dead zone breakpoint compensation method may be different according to the shape of the dead zone. Two different examples will be given below to show how the touch location in the touch area can be modeled according to the shape of the dead zone, and the capacitance value of the touched touch unit in the non-dead zone.
As an example, when the dead zone is formed by a touched touch unit with unchanged capacitance value, the touch point reporting simulation unit 834 acquires a maximum capacitance value and a second maximum capacitance value in a non-dead zone, and determines whether the touched touch unit corresponding to the maximum capacitance value and the touched touch unit corresponding to the second maximum capacitance value are in the same row or the same column, if yes, the position coordinate of the touched touch unit corresponding to the maximum capacitance value is taken as the touch point reporting position; and if not, taking the position coordinate of the touched touch unit corresponding to the dead zone as the report point position.
As another example, when the dead zone is a row or a column composed of a plurality of touched touch units with unchanged capacitance values, the touch point reporting simulation unit 834 acquires a maximum capacitance value and a second maximum capacitance value in a non-dead zone, and determines whether the touched touch unit corresponding to the maximum capacitance value and the touched touch unit corresponding to the second maximum capacitance value are in the same non-dead zone, if so, the position coordinate of the touched touch unit corresponding to the maximum capacitance value is taken as a touch point reporting position; if not, determining the report point position in the touch area according to the touched touch unit corresponding to the maximum capacitance value and the touched touch unit corresponding to the second maximum capacitance value.
The report output module 840 is configured to perform report output on the report position obtained through simulation.
The determining module 850 is configured to determine a target hit point position from the touch area according to the touch data when there is no dead zone in the touch area. As an example, the determining module 850 obtains the touched touch unit with the largest capacitance value from the touch data, and determines the position coordinate of the touched touch unit with the largest capacitance value as the target report point position.
In an embodiment of the present invention, the report output module 840 is further configured to output a report of the target report position.
According to the compensation device for the dead zone of the touch screen, disclosed by the embodiment of the invention, when the touch operation on the touch screen is monitored by the acquisition module, the touch data of the touch area corresponding to the touch operation is acquired, the judgment module judges whether the dead zone exists in the touch area according to the touch data, if so, the dead zone compensation module performs dead zone compensation according to the touch data so as to simulate a report point position, the report point output module performs report point output on the report point position obtained by simulation, if not, the determination module determines a target report point position from the touch area according to the touch data, and the report point output module performs report point output on the target report point position. After the touch screen has the dead zone, the dead zone report point can be compensated according to the capacitance change of the touch units around the dead zone, the real touch position in the touch zone can be determined and output as the report point, and thus, the touch operation acting on the dead zone can be received by the system, the system can make corresponding response according to the touch operation, the touch function of the touch screen can be guaranteed without replacing the touch screen, the problem that the expense of a user and the use cost of electronic equipment are increased due to the replacement of the touch screen is avoided, and the use experience of the user is greatly improved.
