Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, not all, embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
An embodiment of the present invention provides a touch screen detection method, which is applied to a mobile terminal, and as shown in fig. 1, the method includes the following steps:
s100, counting click data of a user on the touch screen, wherein the click data comprises click times and a plurality of click coordinates.
Generally, a touch screen automatic detection program is arranged inside a mobile terminal, and a self-detection mechanism is periodically started according to preset time to judge whether a touch screen is normally used, however, the periodically started self-detection mechanism has many disadvantages, for example, the accumulated use time of the touch screen is very short, detection is not necessary at all, or a self-detection interval is unreasonable, and frequent starting affects the operation experience of a user. Therefore, in order to avoid the problems of low use cost and poor user experience caused by frequent starting of the automatic detection program of the touch screen, the click data of the user on the touch screen can be counted, and then the touch screen is detected according to the click data in the base that the normal use of the mobile terminal by the user is not influenced.
The click data is data generated by the touch screen according to the operation of the user on the touch screen, and can be obtained by statistics of the mobile terminal in the process of using the mobile terminal by the user.
The number of clicks can reflect the usage amount of the touch screen by the user, and the click coordinates can indicate the position of the operation in the touch screen.
S200, judging whether the click times are larger than a first preset time.
The number of clicks can reflect the usage amount of the touch screen by the user, and when the usage amount is large, the touch screen may be abnormal due to the working life, the operation damage of the user and the like, so that whether the abnormal channel exists in the touch screen is detected or not can be determined when the number of clicks is greater than a first preset value.
The first preset number of times may be set by the mobile terminal in advance, for example, according to the size of the touch screen, the number of channels, the channel density, and the like.
For example, the first preset number of times may be 50000.
The channel is a conductive circuit arranged in the touch screen and used for determining a click coordinate aiming at the operation according to the operation of a user on the touch screen.
The touch screen is typically provided with channels in both the lateral and longitudinal directions. When a user operates the touch screen, the capacitance value signal of the channel at the corresponding position in the touch screen is increased, the mobile terminal selects at least one transverse channel and at least one longitudinal channel from the transverse channels and the longitudinal channels according to the capacitance value signal of each channel, calculates the ordinate of the operation according to the capacitance value signal of the at least one transverse channel, and calculates the abscissa of the operation according to the capacitance value signal of the at least one longitudinal channel. And determining the calculated abscissa and ordinate as click coordinates for the operation.
For example, a schematic of the channel is shown in FIG. 2. When a user clicks a certain position (namely, one-click event) on the touch screen, the touch screen selects a channel A with the largest capacitance value signal from the transverse channels according to the capacitance value signals of the channels caused by the operation, and determines a corresponding ordinate according to the capacitance value signal of the channel A. And selecting a channel B with the largest capacitance value signal in the longitudinal channels, and determining the abscissa according to the capacitance value signal of the channel B. And determining the determined abscissa and ordinate as click coordinates for the operation.
S300, when the number of clicks is larger than the first preset number of times, detecting whether an abnormal channel exists in the touch screen or not according to the click coordinates.
When the number of clicks is greater than the first preset number, the usage amount of the touch screen by the user is large, and the probability that the abnormal channel exists in the touch screen is high, so that whether the abnormal channel exists can be detected according to a plurality of click coordinates.
If an abnormal channel exists in the touch screen, the click coordinates for each operation of the user are calculated to possibly have larger errors or abnormal conditions, so that the mobile terminal can compare the click coordinates, judge whether the click coordinates possibly have abnormal click coordinates or not, and further determine that the abnormal channel exists in the touch screen. For example, the mobile terminal may determine that the same click coordinates exist in the plurality of click coordinates, and if the same click coordinates are greater than a fourth preset number of times, it is determined that an abnormal channel exists in the touch screen.
Wherein the fourth preset number of times may be determined in advance by the mobile terminal.
For example, the plurality of click coordinates include 50000 click coordinates, the 50000 click coordinates include 10000 click coordinates (36, 63), the fourth preset number of times is 5000, and since 10000 is greater than 5000, it is determined that an abnormal channel exists in the touch screen.
Of course, when the number of clicks is not greater than the first preset number, it may be determined whether an abnormal channel exists in the touch screen, but the click data may be counted again.
In the embodiment of the invention, click data such as click times, click coordinates and the like can be counted, whether the touch screen is detected or not is determined according to the click times, and whether an abnormal channel exists in the touch screen or not is detected according to the click coordinates. The operation of counting the click data can be performed in the process that a user normally uses the mobile terminal provided with the touch screen, so that the touch screen does not need to be detected regularly through a self-checking mechanism, the problems of use cost and poor user experience caused by frequent starting of an automatic detection program of the touch screen are further solved, namely, the accuracy of detection of the touch screen can be improved, and the user experience is improved.
Preferably, the step S300 of detecting whether an abnormal channel exists in the touch screen according to the plurality of click coordinates includes: judging whether the number of the click coordinates corresponding to each channel in the touch screen is smaller than a second preset number of times, and determining that the channel is open-circuited when the channel with the number of the click coordinates smaller than the second preset number of times exists in the touch screen.
The abnormal condition of the channel usually includes open circuit or short circuit, so in order to accurately detect whether an abnormal channel exists in the touch screen and the type of the abnormal channel, that is, to improve the accuracy of the detection of the touch screen, whether the open circuit channel exists can be judged according to the number of the click coordinates corresponding to each channel.
If a certain channel is broken, the capacitance value signal of the channel may be abnormal, so that it is difficult to determine the ordinate or abscissa, and thus it is difficult to determine the click coordinate for the user operation, and therefore, in the multiple click coordinates, the click coordinate corresponding to the channel may not be included or may be rarely included, and therefore, for any channel, if the number of click coordinates corresponding to the channel is less than the second preset number, it may be determined that the channel is broken.
The mobile terminal can determine a click coordinate set corresponding to each channel in advance according to the distribution of each channel in the touch screen, wherein each click coordinate in the click coordinate set is in a preset range corresponding to the channel. And then classifying the plurality of click coordinates according to the set of click coordinates corresponding to each channel, thereby obtaining the click coordinates corresponding to each channel.
The preset range may be determined in advance according to the distribution mode of each channel, for example, the number of pixels in how many pixels a certain coordinate point on the channel is as a circle center may be included, the number of pixels is related to the screen body design of the touch screen, and for different screen body designs, different numbers of pixel points may be defined.
For example, taking channel B as an example, the click coordinate set corresponding to the channel may include any click coordinate with an abscissa of 36. Therefore, in 50000 click coordinates, 5000 click coordinates with an abscissa of 36 are included, and the 5000 click coordinates are click coordinates corresponding to the channel.
Of course, in practical applications, the mobile terminal may also classify each click coordinate according to the corresponding channel when counting the click data, so as to directly judge whether there is an open channel according to the click coordinate corresponding to each channel when judging whether there is an abnormal channel in the touch screen.
The second preset number of times may be predetermined by the mobile terminal. For example, the second predetermined number may be 0.
Preferably, in S300, the multiple click coordinates include at least one coordinate group, the multiple click coordinates in the same coordinate group are triggered at the same time, and abscissa or ordinate of different click coordinates in the same coordinate group are the same, and the detecting whether there is an abnormal channel in the touch screen according to the multiple click coordinates includes: determining the number of target coordinate groups for any non-intersected channels, wherein the target coordinate groups comprise click coordinates respectively corresponding to the channels, judging whether the determined number is larger than a third preset number of times, and determining that a short-circuited abnormal channel exists in the touch screen when the determined number is larger than the third preset number of times.
The abnormity of the channel usually comprises open circuit or short circuit, so that whether the abnormal channel exists in the touch screen and the type of the abnormal channel is accurately detected, namely, the detection accuracy of the touch screen is improved, and whether the short-circuited channel exists in the touch screen can be judged according to a plurality of click coordinates.
If there are any non-intersecting channels (e.g., more than two transverse channels, or more than two longitudinal channels) in the touch screen that are shorted, the capacitance signals of these channels caused by the user's operation may be the same, which may result in more than one click coordinate being calculated for one operation, and the abscissa or ordinate of the more than one click coordinate determined by the shorted channels is the same. For example, as shown in fig. 2, there is a short circuit between the channel C and the channel a in the horizontal direction, after the user operates the touch screen, because the capacitance signals of the channel a and the channel C are the same, a click coordinate can be calculated according to the channel a and the channel B, and a click coordinate is also calculated according to the channel C and the channel B, and the ordinate of the two coordinates is the same, and the abscissa is different, where the channel for determining different abscissas is the short-circuited channel. Therefore, whether a short-circuited channel exists can be determined according to the click coordinates with the same abscissa or ordinate in the coordinate set.
The mobile terminal can store click coordinates which are triggered at the same time and have the same abscissa or ordinate as a coordinate group when counting the click data.
For each click coordinate in the same coordinate, if the ordinate of each click coordinate is the same, the channel corresponding to the abscissa of each click coordinate may be a short-circuited channel, or if the abscissa of each click coordinate is the same, the channel corresponding to the ordinate of each click coordinate may be a short-circuited channel. Therefore, for any disjoint channels, the number of target coordinates that can account for the short of these channels may be determined, and the target coordinate set includes the click coordinates that respectively correspond to each of the channels in any disjoint channels. And if the determined number is larger than the third preset number, determining that any non-intersected channel is short-circuited, namely a short-circuited channel exists in the touch screen.
The third preset number of times may be determined in advance by the mobile terminal.
For example, for channel a and channel C, 10000 coordinate sets are included in 50000 click coordinates, and 5000 target coordinate sets for channel a and channel C are included in the 10000 coordinate sets, that is, each of the 5000 coordinate sets includes click coordinates for channel a and channel C. If the third preset number is 4000, it may be determined that the channel a and the channel C are short-circuited since 5000 is greater than 4000.
Preferably, after detecting whether an abnormal channel exists in the touch screen according to the plurality of click coordinates in S300, the method further includes: when the abnormal channel exists in the touch screen and the operation on the touch screen is detected, shielding the capacitance value signal of the abnormal channel so as to calculate the click coordinate aiming at the operation through the channel which does not generate the abnormality in the touch screen.
In calculating the click coordinate, the more channels are selected, the more accurate the click coordinate is calculated, and if the number of channels is small, the click coordinate can be calculated, but the click coordinate calculated by the small number of channels may have an error. When an abnormal channel exists in the touch screen, the error of the click coordinate caused by the abnormal channel is usually much larger than the error of the click coordinate caused by one channel, so that in order to improve the accuracy of determining the click coordinate according to the operation of a user, the click coordinate can be calculated according to the normal channel by shielding the capacitance value signal of the abnormal channel.
The mobile terminal can store the channel identification of the abnormal channel after detecting the abnormal channel, collect the capacitance value signal of each channel when detecting the operation of the user for the touch screen, delete the capacitance value signal of the abnormal channel according to the channel identification of each channel, and then select at least one channel from the rest channels according to the capacitance value signals of the rest channels to calculate the click coordinate for the operation.
The channel identifier is used to uniquely identify a channel in the mobile terminal, and may be determined in advance by the mobile terminal, such as numbering by numbers or letters.
Preferably, after the detecting whether an abnormal channel exists in the touch screen according to the plurality of click coordinates, S300 further includes: and when the abnormal channel exists in the touch screen, starting an automatic touch screen detection program to detect the touch screen.
In order to increase the detection dimensionality of the detection of the touch screen and further improve the accuracy of the detection of the touch screen on the basis of reducing the detection cost, an automatic detection program of the touch screen in the mobile terminal can be started to further detect the touch screen when an abnormal channel exists in the touch screen.
The touch screen automatic detection program is used for detecting the touch screen, and can be acquired by the mobile terminal from other devices or servers, for example, downloaded by an application market.
Of course, when it is determined that an abnormal channel exists in the touch screen, the detection result may be displayed to the user in the form of an image, sound, vibration, or the like, and the user may be prompted to replace the touch screen or perform other remedial measures when the abnormal channel is detected.

the counting module 301 is configured to count click data of a user on the touch screen, where the click data includes click times and a plurality of click coordinates;

The operation of counting the click data can be performed in the process that the user normally uses the mobile terminal provided with the touch screen, so that the touch screen does not need to be detected regularly through a self-checking mechanism, the problems of use cost and poor user experience caused by frequent starting of an automatic detection program of the touch screen are further solved, namely, the cost for detecting the touch screen can be reduced, and the user experience is improved.
