Detailed ways

The following describes in detail the embodiments of the present invention, examples of which are illustrated in the accompanying drawings, wherein the same or similar reference numerals refer to the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary, and are intended to explain the present invention and should not be construed as limiting the present invention.

The following describes a method, an apparatus, an electronic device, and a computer-readable storage medium for compensating for a dead zone of a touch screen according to the embodiments of the present invention with reference to the accompanying drawings.

FIG. 1 is a flowchart of a compensation method for a dead zone of a touch screen according to an embodiment of the present 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 can 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 can be configured on the electronic device of 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 compensation method for the dead zone of the touch screen may include:

S110, when a touch operation is detected on the touch screen, acquire touch data of a touch area corresponding to the touch operation, wherein the touch data includes position coordinates of multiple touched touch units and capacitance values of multiple 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. In this way, it can be determined whether there is a touch operation on the touch screen by detecting whether the capacitance value of the touch unit changes. When it is determined that the capacitance values of multiple touch units in the capacitive touch screen have changed, it can be monitored that there is a touch operation on the touch screen, and at this time, the touch data of the touch area corresponding to the touch operation can be acquired.

S120: Determine whether there is a dead zone 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 with no function.

As an example, it can be determined whether there is a touch unit whose capacitance value has not changed 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; Then it is determined that there is a dead zone in the touch area.

That is to say, according to the touch data, it can be judged whether there is a capacitance value of the touched touch unit in the touch area that has not changed. If so, it can be judged that there is a dead zone in the touch area; There is no dead zone in the touch area. The dead zone can be understood as the capacitance value of the area will not change when the user touches the area, so that the system of the electronic device cannot sense the user's touch operation through the area.

S130 , if there is a dead zone in the touch area, perform dead zone compensation according to the touch data to simulate the reported point position, and output the reported point position obtained by the simulation.

Optionally, when it is determined that there is a dead zone in the touch area, the capacitance change of the touch unit at the dead zone position can be simulated according to the change in the capacitance value of the touched touch unit around the dead zone in the touch data. The real touch position is obtained, and the touch position obtained by the simulation is used as the reported point position for reporting point output.

As an example, as shown in FIG. 2 , a specific implementation manner of performing dead zone compensation according to touch data to simulate the position of the reported point may include:

S210 , according to the touch data, determine the touched touch units whose capacitance values have not changed; that is, from the touch data, it can be determined that the capacitance values of the touched touch units have not changed. .

S220: Determine a dead zone and a non-dead zone in the touch area according to the touched touch unit whose capacitance value does not change;

Optionally, in the touch area, the area formed by the touched touch-control units where the capacitance value does not change is used as a dead area, and other areas of the touch area are used as a non-dead area.

S230, determine the shape of the dead zone;

That is to say, the shape of the dead zone can 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 whose capacitance value does not change; in another example, the dead zone may be a row or a column formed by a plurality of touched touch units whose capacitance value does not change.

S240, according to the shape of the dead zone and the capacitance value of the touched touch unit in the non-dead zone, simulate the position of announcing point in the touch area.

Optionally, the real touch position can be determined from 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. In the embodiment of the present invention, according to the different shapes of the dead zone, the adopted dead zone reporting compensation methods are also different. Referring to Figures 3 and 5 below, two different examples will be given to show how to simulate the shape of the dead zone and the capacitance value of the touched touch unit in the non-dead zone. Announcement position in the touch area described above.

As an example, as shown in FIG. 3 , according to the shape of the dead zone and the capacitance value of the touched touch unit in the non-dead zone, simulate the position of the reported point in the touch area. Specific implementations may include:

S2411, when the dead zone is formed by a touched touch unit whose capacitance value has not changed, obtain the maximum value of the capacitance and the second maximum value of the capacitance in the non-dead zone;

It can be understood that when there is a touch operation on the touch screen, the capacitance value of the touch unit on the touch screen will change, and the touch screen IC can determine the specific position of the touch according to the change in the capacitance value of the touch unit. For example, generally take the capacitance value with the largest change. The position of the touch unit is used as the reporting point position, as shown in Figure 4(a), which is a 20*18 touch screen data. The place where the capacitance value changes in the touch screen data is caused by the touch operation. As can be seen from the figure , the position (13, 8) of the touch unit corresponding to the capacitance value "399" is the real touch position (ie, the reported point position). However, when the touch screen fails, causing a certain touch unit to become a dead zone, the specific position of the touch cannot be detected, and the correct touch position cannot be identified at this time.

In this step, when the dead zone is formed by a touched touch unit whose capacitance value does not change, the maximum value of the capacitance and the second maximum value of the capacitance in the non-dead zone can be obtained first. For example, as shown in Figure 4(b) and Figure 4(c), the touch unit with a capacitance value of 0 in the touch area in the figure is the dead zone (the circle area in the figure). At this time, the touch can be acquired The maximum value of capacitance and the second largest value of capacitance in the non-dead zone in the region. For example, as shown in Figure 4(b), the maximum value of the capacitance and the second maximum value of the capacitance in the non-dead zone in this figure are "399" and "381" respectively. As shown in Figure 4(c), the non-dead zone in this figure is The maximum value of capacitance and the second maximum value of capacitance in the area are "381" and "318", respectively.

S2412, determine whether 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 row or column;

S2413, if yes, use the position coordinate of the touched touch unit corresponding to the maximum capacitance value as the reported point position;

That is to say, when the touched touch unit corresponding to the largest capacitance value and the touched touch unit corresponding to the next largest capacitance value are in the same row or column, it can be considered that the dead zone is not the center of the touch area.

For example, as shown in Figure 4(a), when there is a touch operation on the touch screen, in the capacitance change data of the normal touch unit, the capacitance value of the center point position (such as the position of coordinates (13, 8)) has the largest change in capacitance , the peripheral capacitance changes will decrease in turn outward. When the touch screen fails, causing a touch unit to become a dead zone, as shown in Figure 4(b), the touch unit at coordinates (12, 8) is a dead zone. At this time, the touch unit in the non-dead zone The touched touch unit corresponding to the maximum capacitance value (“399”) and the touched touch unit corresponding to the next largest capacitance value (“381”) are in the same column. At this time, the touched touch unit corresponding to the capacitance maximum value can be The position of the control unit is the real touch position, and the position coordinates are used as the reported point position.

S2414, if not, use the position coordinates of the touched touch unit corresponding to the dead zone as the reported point position.

That is to say, when the touched touch unit corresponding to the largest capacitance value and the touched touch unit corresponding to the next largest capacitance value are not located in the same row and/or the same column, the touch sensitive unit corresponding to the dead zone can be touched. The position coordinates are used as the reported point position.

For example, as shown in Figure 4(c), the touch unit at coordinates (13, 8) is a dead zone. At this time, the touch unit corresponding to the maximum capacitance value (“381”) in the non-dead zone corresponds to the touch unit being touched. The touched touch unit corresponding to the next largest capacitance value (“318”) is in a different column and row. At this time, the position of the touched touch unit corresponding to the dead zone can be regarded as the real touch position, and the touch The position coordinates are used as the reported point position.

Therefore, by judging whether the touched touch unit corresponding to the largest capacitance value in the non-dead area and the touched touch unit corresponding to the next largest capacitance value are in the same row or column, the real touch area in the touch area is determined. Touch the position of the point, so that even after a dead zone appears on the touch screen, the touch screen can output the report point on the dead zone to the system of the electronic device, so that the touch operation acting on the dead zone is not affected, and the touch function of the touch screen is guaranteed. .

As another example, as shown in FIG. 5 , according to the shape of the dead zone and the capacitance value of the touched touch unit in the non-dead zone, the position of the reporting point in the touch area is simulated The specific implementation can include:

S2421, when the dead zone is a row or a column composed of a plurality of touched touch units whose capacitance values have not changed, obtain the maximum value of the capacitance and the second maximum value of the capacitance in the non-dead zone;

For example, as shown in Fig. 6(a) and Fig. 6(b), the dead zone is a column composed of a plurality of touched touch units whose capacitance values do not change, as shown in Fig. 7(a) and Fig. 7(b) ), respectively, the dead zone is a row composed of a plurality of touched touch units whose capacitance values do not change. At this time, the dead zone will divide the touch area into three parts, namely: one dead zone and two non-dead zones, and at this time, the maximum value of capacitance and the next largest value 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 sequence; as shown in Fig. 6(b), The maximum value of capacitance and the second maximum value of capacitance are "381" and "281" in turn; as shown in Figure 7(a), the maximum value of capacitance and the second maximum value of capacitance in this dead zone are "399" and "318" in turn; As shown in Fig. 7(b), the maximum value of the capacitance and the second maximum value of the capacitance in the dead zone are "381" and "272" in turn.

S2422, determine whether the touched touch unit corresponding to the maximum capacitance value and the touched touch unit corresponding to the next largest capacitance value are in the same non-dead zone;

S2423, if yes, use the position coordinate of the touched touch unit corresponding to the maximum capacitance value as the reported point position;

For example, taking the dead zone as an example of a row composed of a plurality of touched touch units whose capacitance values have not changed, as shown in Figure 6(a), it can be determined that the touched touch unit and the capacitance corresponding to the maximum capacitance value The touched touch unit corresponding to the next largest value is in the same non-dead zone. At this time, the position coordinate of the touched touch unit corresponding to the maximum capacitance value can be used as the reported point position, and the capacitance value "399" can be corresponding to The position coordinates (13, 8) of the touch control unit are used as the reported point position.

For another example, taking the dead zone as an example of a row composed of a plurality of touched touch units whose capacitance values have not changed, as shown in Figure 7(a), it can be determined that the touched touch unit corresponding to the maximum capacitance value is the same as the touch unit. The touched touch unit corresponding to the second largest value of the capacitance is in the same non-dead zone. At this time, the position coordinate of the touched touch unit corresponding to the largest value of the capacitance can be used as the reported point position, and the capacitance value can be set to "399" The position coordinates (13, 8) of the corresponding touch unit are used as the reported point position.

S2424 , if not, determine the reported 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 next largest 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 next largest capacitance value are not in the same non-dead zone, at this time, the touch control unit corresponding to the maximum capacitance value can be determined. The touch control unit and the touched touch unit corresponding to the second largest capacitance value are touched, and the position coordinates of the touch unit between the two are used as the reported point position of the touch area.

For example, taking the dead zone as an example of a column composed of a plurality of touched touch units whose capacitance values have not changed, as shown in Figure 6(b), it can be determined that the touched touch unit and the capacitance corresponding to the maximum capacitance value The touched touch unit corresponding to the second largest value is in a different non-dead zone. In this case, the touch touch unit corresponding to the maximum capacitance value and the touched touch unit corresponding to the second largest value of the capacitance can be touched. The position coordinates (13, 8) of the unit are used as the reported point position.

For another example, taking the dead zone as an example of a row consisting of a plurality of touched touch units whose capacitance values have not changed, as shown in Figure 7(b), it can be determined that the touched touch unit corresponding to the maximum capacitance value and the The touched touch unit corresponding to the second largest capacitance value is in a different non-dead zone. In this case, the touch touch unit corresponding to the largest capacitance value and the touched touch unit corresponding to the next largest capacitance value can be touched. The position coordinates (13, 8) of the control unit are used as the reported point position.

Therefore, the real touch in the touch area is determined by judging whether the touched touch unit corresponding to the largest capacitance value in the touch data and the touched touch unit corresponding to the next largest capacitance value are in the same non-dead zone. In this way, even after a certain column or row on the touch screen becomes a dead zone, the touch screen can output the report point on the dead zone to the system of the electronic device, so that the touch operation acting on the dead zone is not affected, ensuring that The touch function of the touch screen is enabled.

S140, if there is no dead zone in the touch area, determine the target report point position from the touch area according to the touch data, and output the target report point position.

As an example, the touched touch unit with the largest capacitance value may be obtained from the touch data, the position coordinates of the touched touch unit with the largest capacitance value may be determined, and the capacitance The position coordinate of the touched touch unit with the largest value is determined as the target reporting point position. That is to say, when there is no dead zone in the touch area, it can be considered that the capacitance value in the touch area changes normally, and at this time, the position of the touch unit corresponding to the maximum capacitance in the touch area can be touched. The coordinates are output as the reported point position of the touch area.

According to the compensation method for the dead zone of the touch screen according to the embodiment of the present invention, when a touch operation is detected on the touch screen, the touch data of the touch area corresponding to the touch operation is obtained, and whether there is a dead zone in the touch area is judged according to the touch data, and if so, Then carry out dead zone compensation according to the touch data to simulate the position of the reported point, and output the reported point obtained by the simulation. Point position for reporting point output. That is, after a dead zone occurs on the touch screen, the dead zone report point can be compensated according to the capacitance change of the touch unit around the dead zone, and the real touch position in the touch area can be determined and output as a report point, so that the effect of The touch operation in the dead zone can also be received by the system, and then the system can respond accordingly according to the touch operation, the touch function of the touch screen can be guaranteed without replacing the touch screen, and the user's expenditure and electronic The cost of using the equipment greatly improves the user experience.

Corresponding to the compensation methods for the dead zone of the touch screen provided by the above-mentioned embodiments, an embodiment of the present invention further provides a compensation device for the dead zone of the touch screen. The compensation methods for the dead zone of the touch screen provided in several embodiments correspond to each other. Therefore, the foregoing embodiments of the compensation method for the dead zone of the touch screen are also applicable to the compensation device for the dead zone of the touch screen provided in this embodiment, which is not detailed in this embodiment. describe. FIG. 8 is a schematic structural diagram of a device for compensating dead zones of a touch screen according to an embodiment of the present invention. It should be noted that the device for compensating the dead zone of the touch screen in the embodiment of the present invention may be configured on the electronic device in 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, and the capacitive touch screen may include a plurality of touch units.

As shown in FIG. 8 , the touch screen dead zone compensation device 800 may include: an acquisition module 810 , a judgment module 820 , a dead zone compensation module 830 , a report point output module 840 and a determination module 850 .

Specifically, the acquisition module 810 can be configured to acquire touch data of the touch area corresponding to the touch operation when a touch operation is detected on the touch screen, wherein the touch data includes the position coordinates of a plurality of touched touch units and a plurality of touched touch units. Capacitance value of the control unit.

The judgment module 820 is configured to judge whether there is a dead zone in the touch area according to the touch data, wherein the dead zone is used to indicate that the touch screen touches a damaged area with no function. As an example, the determination module 820 may determine whether there is a touch unit whose capacitance value does not change in the touch area according to the touch data, and if not, determine that there is no dead zone in the touch area; If there is, it is determined that there is a dead zone in the touch area.

The dead zone compensation module 830 is configured to perform dead zone compensation according to the touch data when there is a dead zone in the touch area, so as to simulate the position of the reporting point. As an example, as shown in FIG. 9 , the dead zone compensation module 830 may include: a first determination unit 831 , a second determination unit 832 , a third determination unit 833 , and an alarm point simulation unit 834 . Wherein, the first determination unit 831 is used to determine the touched touch unit whose capacitance value has not changed according to the touch data; the second determination unit 832 is used to determine the touched touch unit whose capacitance value has not changed according to the touch touch unit. Dead zone and non-dead zone in the area; the third determination unit 833 is used to determine the shape of the dead zone; the reporting point simulation unit 834 is used to determine the shape of the dead zone and the capacitance value of the touched touch unit in the non-dead zone , simulating the position of announcing point in the touch area.

In the embodiment of the present invention, according to the different shapes of the dead zone, the adopted dead zone reporting compensation methods are also different. Two different examples will be given below to illustrate how to simulate the position of the touch point 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.

As an example, when the dead zone is formed by a touched touch unit whose capacitance value does not change, the alarm point simulation unit 834 obtains the maximum value of the capacitance and the next largest value of the capacitance in the non-dead zone, and determines the maximum value of the capacitance Whether the corresponding touched touch unit and the touched touch unit corresponding to the second largest capacitance value are in the same row or the same column, if so, use the position coordinates of the touched touch unit corresponding to the maximum capacitance value as the reported point position; If not, the position coordinate of the touched touch unit corresponding to the dead zone is used as the reported point position.

As another example, when the dead zone is a row or a column composed of a plurality of touched touch units whose capacitance values have not changed, the alarm point simulation unit 834 obtains the maximum value of the capacitance and the next largest value of the capacitance in the non-dead zone , and determine whether the touched touch unit corresponding to the maximum capacitance value and the touched touch unit corresponding to the next largest capacitance value are in the same non-dead zone, and if so, determine the position of the touched touch unit corresponding to the maximum capacitance value The coordinates are used as the reported point position; if not, the reported point position in the touch area is determined according to the touched touch unit corresponding to the maximum capacitance value and the touched touch unit corresponding to the second largest capacitance value.

The reporting point output module 840 is used for reporting the point reporting position obtained by the simulation.

The determining module 850 is configured to determine the position of the target reporting point 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, determines the position coordinates of the touched touch unit with the largest capacitance value, and assigns the touched touch unit with the largest capacitance value The position coordinates are determined as the target reporting point position.

Wherein, in the embodiment of the present invention, the reporting point output module 840 is further configured to perform reporting point outputting of the target reporting point position.

Dead zone, if it is, the dead zone compensation module will perform dead zone compensation according to the touch data to simulate the position of the report point, and the report point output module will output the signal point position obtained by the simulation, if not, determine the module according to the touch data. The position of the target report point is determined from the touch area, and the report point output module outputs the target report point position. That is, after a dead zone occurs on the touch screen, the dead zone report point can be compensated according to the capacitance change of the touch unit around the dead zone, and the real touch position in the touch area can be determined and output as a report point, so that the effect of The touch operation in the dead zone can also be received by the system, and then the system can respond accordingly according to the touch operation, the touch function of the touch screen can be guaranteed without replacing the touch screen, and the user's expenditure and electronic The cost of using the equipment greatly improves the user experience.

In order to realize the above embodiments, the present invention also provides an electronic device.
