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.
The embodiment of the invention provides a capacitive screen calibration method, which mainly aims at the problems of high cost, long time, low efficiency and the like when a capacitive screen is calibrated in a manual mode in the prior art.
The capacitive screen calibration method provided by the invention divides the capacitive screen into N different areas according to a preset rule, then simulates K touch screen events in the ith area of the N different areas, counts the number L of touch screen events actually acquired in the ith area, and finally adjusts the sensitivity of the capacitive screen according to the difference value between the simulated K touch screen events and the actually acquired number L of touch screen events respectively corresponding to each area. From this, when carrying out the calibration to the electric capacity screen, realized automatic calibration, reduced the cost of artifical calibration cost, saved calibration time, effectively promoted the efficiency of electric capacity screen calibration, promoted user experience.
The following describes in detail a calibration method for a capacitive screen according to an embodiment of the present invention with reference to the accompanying drawings.
Fig. 1 is a flowchart of a capacitive screen calibration method according to an embodiment of the present invention.
As shown in fig. 1, the capacitive screen calibration method may include the following steps:
Specifically, the capacitive screen calibration method provided in this embodiment may be executed by the capacitive screen calibration apparatus provided in the present invention, where the capacitive screen calibration apparatus is configured in a terminal device to perform calibration control on a capacitive screen.
In specific implementation, the capacitive screen can be divided into N different areas according to the size of the capacitive screen; or dividing the capacitive screen into N different areas according to the performance parameters of the terminal to which the capacitive screen belongs; or, the capacitive screen is divided into N different areas according to the size of the capacitive screen and the performance parameters of the terminal to which the capacitive screen belongs.
Preferably, in this embodiment, the capacitive screen is divided into N different areas according to the size of the capacitive screen and the performance parameters of the terminal to which the capacitive screen belongs.
The performance parameters of the terminal to which the capacitive screen belongs may include, but are not limited to, a Central Processing Unit (CPU) core number, a CPU frequency, and the like, which is not specifically limited in this application.
For example, if the size of the capacitive screen in this embodiment is 5.5 inches, the central processing unit of the device to which the capacitive screen belongs is dual core, and the frequency is 1.4GHz, the capacitive screen may be divided into 2000 different areas.
For another example, if the size of the capacitive screen is 5.5 inches, the central processing unit of the terminal to which the capacitive screen belongs is four cores, and the frequency is 2.4GHz, then the capacitive screen can be divided into 3000 different areas.
That is to say, the number of the divided areas of the capacitive screen is determined according to the processing capacity of the central processing unit of the terminal to which the capacitive screen belongs and the size of the capacitive screen, so that the problem that the central processing unit in the terminal equipment is mainly used for processing the calibration of the capacitive screen due to the limited capacity of the central processing unit of the terminal and the excessive division of the area of the capacitive screen, so that other programs cannot normally run can be effectively avoided, the programs in the equipment to which the capacitive screen belongs and the calibration of the capacitive screen can be simultaneously carried out, and the requirement that the terminal normally runs other programs is met.
And 102, simulating K times of touch screen events in the ith area, wherein i is a positive integer which is greater than or equal to 1 and less than or equal to N, and K is a positive integer.
Specifically, after the capacitive screen is divided into N different regions, a simulated touch event may be performed on each of the N different regions.
The times of the simulation touch events corresponding to each area can be the same or different, and the K times of simulation touch screen events can be adaptively set according to actual needs. Such as 10, 20, etc., which is not specifically limited by the present application.
For example, if the number of N different areas is 20, and the number of times of simulating the touch screen event in each area is 10 times of touching in 10 seconds(s), the operation of simulating the number of times of the touch screen event in 10 seconds may be performed in each of the 20 different areas.
And 103, counting the number L of touch screen events actually acquired in the ith area.
Specifically, the capacitive screen may jump due to the influence of the temperature, humidity, static electricity, etc. of the environment where the capacitive screen is located. Therefore, the frequency L of the touch screen event actually acquired may be different from the frequency K of the actual simulation, and therefore, in the embodiment of the application, the probability of screen jump occurring in each area of the current capacitive screen may be determined by counting the frequency of the touch screen event actually acquired in each area.
And 104, adjusting the sensitivity of the capacitive screen according to the difference value of the K and the L corresponding to each area.
Specifically, the difference between K and L corresponding to each region is the number of screen skipping in the region. Different electronic devices are distributed at different positions of the terminal mainboard, so that screen jumping times corresponding to different positions of the capacitive screen under the same environment are possibly different. Therefore, in the embodiment of the application, the capacitive screen is divided into the plurality of areas, and the sensitivity of the capacitive screen is adjusted according to the screen jumping times corresponding to each area, so that the overall reliability and accuracy of the capacitive screen are improved.
In specific implementation, the difference value between the simulated touch screen event frequency K and the actual touch screen event frequency L can be differentiated from the threshold value to obtain compensation values for sensitivity adjustment of different areas, and then the sensitivity of different areas in the capacitive screen is adjusted according to the compensation values, so that the purpose of sensitivity adjustment of the capacitive screen is achieved.
In the calibration method for the capacitive screen, the capacitive screen is divided into N different areas according to a preset rule, then multiple touch screen events are simulated in an ith area of the N different areas in sequence, the number of times of touch screen events actually acquired in the ith area is counted, and the sensitivity of the capacitive screen is adjusted according to the difference between the number of times of simulated K touch screen events and the number of times of touch screen events actually acquired, which correspond to each area. From this, through dividing into a plurality of regions with the electric capacity screen to according to the screen jumping number of times in each region, carry out automatic calibration to the electric capacity screen, reduced the cost of artifical calibration cost, saved calibration time, effectively improved the efficiency of electric capacity screen calibration, promoted user experience.
According to the analysis, the sensitivity of the capacitive screen is adjusted according to the difference value between the number of times of the simulated touch screen events corresponding to each area and the number of times of the touch screen events actually acquired. In a possible implementation scenario of the present invention, when the difference value corresponding to each different area is large, each area may be first screened according to the difference value corresponding to each area, and then the sensitivity of the capacitive screen is adjusted only according to the difference value corresponding to a part of the areas. The calibration method of the capacitive screen in the above case is further described with reference to fig. 2.
Fig. 2 is a flowchart of a capacitive screen calibration method according to another embodiment of the invention.
As shown in fig. 2, the calibration method for a capacitive screen according to an embodiment of the present invention may include the following steps:
And step 203, counting the number L of touch screen events actually acquired in the ith area.
And step 204, determining whether to adjust the sensitivity of the capacitive screen or not according to the difference value of the K and the L and the threshold value respectively corresponding to each area, if so, executing step 205, and otherwise, not performing any processing.
Specifically, the difference between K and L corresponding to each region is the number of screen skipping in the region. Different electronic devices are distributed at different positions of the terminal mainboard, so that screen jumping times corresponding to different positions of the capacitive screen under the same environment are possibly different. Therefore, in the embodiment of the application, the capacitive screen is divided into the plurality of areas, and whether the sensitivity of the capacitive screen is adjusted or not is determined according to the screen jumping times and the threshold value corresponding to each area, so that the overall reliability and accuracy of the capacitive screen are improved.
In specific implementation, the difference between K and L corresponding to each region is compared with a threshold, and if the difference between K and L corresponding to each region is greater than the threshold, or if the difference between K and L corresponding to at least M regions is greater than the threshold, the technical parameter of the capacitive screen is adjusted, where M is a positive integer greater than 1.
The threshold may be specifically set according to an actual use condition, and the present application is not particularly limited to this.
It should be noted that, in this embodiment, when it is determined that the sensitivity of the capacitive screen needs to be adjusted, parameters of the capacitive screen, such as operating voltage, current, self-capacitance, and mutual capacitance, may be adjusted to achieve the purpose of adjusting the sensitivity of the capacitive screen.
For example, if the number of N different regions of the capacitive screen is 10, and the number of times of simulating the touch screen event in each region is 10 times per 10 seconds(s), and the difference threshold is 5, when the number of times of acquiring the touch screen actually acquired by 2 regions in 10s among the 10 regions is as many as 70 times, the difference is much greater than 5, the number of times of acquiring the touch screen actually acquired by the remaining 8 regions in 10s is all around 10 times, and the difference is less than 5, the number of times of acquiring the touch screen actually is as many as 70 times, and the difference of the 2 regions greater than 5 is excluded, and the difference obtained by the remaining 8 regions is used as a difference reference set.
That is to say, the area where the difference between the actually captured touch screen times and the simulated touch screen times is far larger than or far smaller than the threshold is removed, so as to avoid the adverse effect of the abnormal area on the calibration of the sensitivity of the capacitive screen.
And step 206, determining the average screen jumping times corresponding to the capacitive screen according to the difference value reference set.
Specifically, the obtained difference values in the difference value reference set are weighted and averaged to obtain the average screen jumping times corresponding to the capacitive screen.
And step 207, adjusting the sensitivity of the capacitive screen according to the average screen jumping times.
And the difference value between the average screen jumping number and the threshold value is used as a compensation value of the sensitivity, and the sensitivity compensation is carried out on the capacitive screen.
Further, in another embodiment of the present invention, the capacitive screen calibration method further includes:
and 208, repeatedly executing operations of simulating K times of touch screen events in the ith area based on the adjusted sensitivity parameters and adjusting the sensitivity of the capacitive screen according to the difference value between the number L of times of actually acquired touch screen events and K until the difference value between the K and the L corresponding to each area is determined to be in a preset range.
Specifically, after the sensitivity of the capacitive screen is adjusted once, the difference between K and L corresponding to each of N different regions in the capacitive screen is not all within the preset range.
Therefore, in order to enable the difference value of the K and the L corresponding to each of the N different areas to be within a preset range, so as to ensure that the sensitivity of the capacitive screen meets the requirement and is relatively stable, the method and the device further repeat the sensitivity adjustment of the capacitive screen for multiple times in each area, iterate the sensitivity for multiple times until the sensitivity of the capacitive screen is within the preset range, thereby eliminating the existing error and enabling the sensitivity of the adjusted capacitive screen to be more stable.
In the calibration method for the capacitive screen, the difference reference set is determined according to the difference value of the K and the L corresponding to each region in the capacitive screen, the average screen jumping frequency corresponding to the capacitive screen is determined according to the difference reference set, and the sensitivity of the capacitive screen is adjusted according to the average screen jumping frequency, so that the calibration of the capacitive screen is more accurate, the calibration precision of the capacitive screen is improved, the user requirements are further met, and the user experience is improved.
