Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention is described in further detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.
In the embodiment shown in fig. 1, a touch data processing method is provided, which can be applied to the touch system 100 shown in fig. 2.
Referring to fig. 2, the touch system 100 includes: a control module 101 and a touch screen 102.
The control module 101 is configured to execute the touch data processing method in fig. 1, and implement control over the touch screen by executing the touch data processing method in fig. 1.
The touch screen 102 includes a display area a, and a touch electrode 104 and a touch node 106 arranged at the back of the display area, wherein the touch node 106 is a sensor capable of detecting a change of a touch parameter. In the present application, the touch nodes 106 are arranged in the display area a, generally, one touch node 106 can detect the touch parameters within a set range, and based on the distribution of the touch nodes 106, the display area a can be divided into a plurality of arranged sensing areas, where each sensing area corresponds to one touch node 106.
Specifically, the touch node 106 can perform sensitive sensing detection on a touch event occurring in the sensing area, and can convert the touch event into an electrical signal or other information in a desired form according to a certain rule for output. If the sensing area is clicked by a finger, the touch node 106 can sensitively detect the touch pressure and convert the touch pressure into a corresponding sensing value according to a set corresponding relationship.
It should be noted that, in addition to the above-mentioned touch event, the sensing value output by the touch node 106 may also be affected by environmental factors, that is, when the same touch event is executed in different environments, the sensing values output by the touch nodes are different, and a "ghost point" may occur in an extreme environment, where the ghost point refers to a larger sensing value output by the touch node 106, which is mistaken for a touch event, due to the influence of the extreme environment when the touch event does not occur.
In order to solve the problem of "ghost points" caused by extreme environmental factors, the application provides a touch data processing method, which further performs data processing on the sensing values of the sensing areas acquired by the touch nodes, and further eliminates false detection of a touch event, as shown in fig. 1, the touch data processing method specifically includes the following steps:
step 202: and acquiring the induction value of each induction area on the touch screen, wherein the induction area comprises a touch induction area and a non-touch induction area.
The display area a of the touch screen 102 is divided into a plurality of sensing areas in advance, each sensing area is provided with a touch electrode 104 and a touch node 106, the touch node 106 performs real-time sensing detection on the corresponding sensing area to obtain a sensing value of each sensing area, and the touch electrode 104 sends the detected sensing value of each sensing area to the control module 101.
The touch screen 102 displays a to-be-displayed picture sent by a higher-level terminal, and the higher-level terminal carries a touch-enabled area and a non-touch-enabled area corresponding to the to-be-displayed picture when sending the to-be-displayed picture to the touch screen 102. The touch data processing method of this embodiment performs different processing on the sensing values of the touch-enabled area and the non-touch-enabled area, so as to suppress the non-touch-enabled area to overcome the problem of "ghost points", and to keep the sensing values of the touch-enabled area, thereby avoiding that the sensing amount of the finger touch area is greatly reduced and the dead point is generated when the finger sensing amount of the touch operation is not so large.
Step 204: and judging whether the induction value of the induction area with the preset number/ratio is larger than a noise threshold value.
The control module 101 receives the sensing values of the sensing areas sent by the touch electrode 104, and determines whether the sensing value of each sensing area is greater than a preset fluctuation value, and when the sensing values of the sensing areas with preset number or preset ratio are greater than the preset fluctuation value, it is determined that the current sensing value is affected by environmental factors and fluctuates.
In this embodiment, the preset fluctuation value is greater than or equal to the fluctuation of the sensing value that can be caused in the normal environment. The specific value of the fluctuation value can be specifically set according to the sensitivity required by the touch screen. In one embodiment, if the environment of the touch screen is an extreme environment, the actual sensing value fluctuation caused by the environment of the touch screen can be used as the noise threshold. For example, if the actual fluctuation range of the sensing value brought by the environment of the touch screen is 100-120, 100 may be used as the preset fluctuation value.
Taking the data array of 7 × 7 as an example, the sensing values of the touch areas that are not affected by the environment or slightly fluctuated by the environment are shown in fig. 3, the area 3 × 3 in the center of fig. 3 is a touch area, the peripheral area is a non-touch area, under normal noise, the range of the sensing values of the touch area is 100-. When the sensing value of each touch area is affected by the environment, as shown in fig. 4, the data is lifted up as a whole, and the sensing value in the non-touch area exceeds 100, in this case, the control module 101 may identify the sensing area with the non-touch area exceeding 100 as being touched, so as to cause an error. In fig. 4, if the preset fluctuation value is 100 and the occupancy ratio of the sensing area with the sensing value greater than 100 is up to 70%, it can be determined that the data fluctuation exists in the sensing value detected this time, or the noise threshold value may be 120, and the higher the occupancy ratio of the sensing area with the sensing value greater than 120 is 50%, it can also be determined that the data fluctuation exists in the sensing value detected this time.
In one embodiment, it is determined whether the sensing value of the non-touchable area with the preset number/ratio is greater than the noise threshold, and it is determined that the data fluctuation exists in the sensing value detected this time. That is, only the magnitude of the sensing value of the non-touchable area is determined, the sensing value of the non-touchable area should be smaller than the noise threshold under normal conditions, and if the sensing value of a large proportion or a large number of non-touchable areas is larger than the noise threshold, it can be determined that the current sensing value is affected by the environmental factors, and data correction needs to be performed on the sensing value of each sensing area.
Only whether the induction value of the non-touch area is larger than the noise threshold value is judged, so that the calculation amount of the control module 101 can be reduced, and the touch data processing efficiency is improved.
Step 206: and carrying out first suppression processing on the induction value of the non-touch area, and carrying out second suppression processing on the induction value of the touch area, wherein the first suppression processing is different from the second suppression processing.
In this embodiment, the touch area and the non-touch area in the touch screen are distinguished, and after it is determined that each sensing area reaches the set data fluctuation, differentiated suppression processing is performed on the touch area and the non-touch area, so that the touch event information of the touch area can be retained while the information of the non-touch area is eliminated.
In one embodiment, the first suppression process is to reduce the sensing value of the non-touchable area to a set threshold, and in another embodiment, the first suppression process is to reduce the sensing value of the non-touchable area to zero.
The second suppression processing is to leave the maximum sensing value in the touchable area unchanged, and the touchable area at least includes one sensing value. In another embodiment, if the touchable region includes a plurality of sensing values, such as a center region of 3 × 3 of the touchable region in fig. 3 and 4, that is, one touchable region corresponds to a plurality of touch nodes, and the plurality of touch nodes sense and detect the plurality of sensing values, at this time, the second suppression processing is to reserve the maximum sensing value in the touchable region and perform suppression processing on other sensing values based on a noise threshold, such as subtracting the noise threshold from an actually detected sensing value or subtracting the noise threshold corrected by a correction coefficient from an output value of the other sensing values.
In another embodiment, the second suppression processing executes the following formula (1):
Dataout＝DataMax-(DataMax-Datain)·DataMax/(DataMax-noise threshold) (1)
Wherein the DataMaxIs the maximum induction value in the touch-controllable area, DatainData for obtaining the induction value of the target induction regionoutAnd the induction value of the target induction area output after the second inhibition processing.
By executing the formula (1), the maximum sensing value in the touch area can be kept unchanged, and other sensing values of the touch area are correspondingly inhibited through two parameters, namely the maximum sensing value DataMax and the noise threshold of the touch area, so that the finally output sensing value is close to the sensing value in the normal environment.
In another embodiment, the first suppression process is: the first suppression processing is to reduce the sensing value of the non-touchable area with the sensing value smaller than the noise threshold to 0, and perform the second suppression processing as shown in the above formula (1) on the non-touchable area with the sensing value larger than the noise threshold. By applying the suppression processing means to the non-touch area, the sensing value finally output by the non-touch area can be close to the sensing value in the normal environment.
In one embodiment, as shown in fig. 5, the touch data processing method specifically includes the following steps: :
step 502: the method comprises the steps of obtaining a picture to be displayed, and identifying a touch area and a non-touch area in the picture to be displayed.

Determining a touchable area and a non-touchable area in the picture to be displayed as follows: searching a touch area associated with the picture to be displayed, if the touch area is searched, completing analysis, if the touch area is not searched, identifying a touch page element in the picture to be displayed, and determining a display subarea of the touch page element in the display area according to the corresponding relation between the picture to be displayed and the display area of the touch screen and the corresponding relation between the touch page element and the picture to be displayed, wherein the display subarea is a touch area and the touch area is associated with the touch page element; and establishing a connection relation between the touch area and the page identifier of the picture to be displayed.
And determining a display subarea corresponding to the touch-controllable page elements in the display area according to the corresponding relation between the to-be-displayed picture and the display area of the touch screen and the corresponding relation between the touch-controllable page elements and the to-be-displayed picture, wherein the display subarea is the touch-controllable area, and each touch-controllable area is associated with one touch-controllable page element. The method specifically comprises the following steps: the relative position relationship between the touch page element and the picture to be displayed is the same as the relative position relationship between the display sub-area and the display area. The display sub-area includes at least one touch node, and areas corresponding to a1 and a2 in fig. 2 are touchable areas.
By the mode, when the touch display screen executes a certain program for display, the touch area (including the position information of the touch area and the corresponding page element) is determined only by identifying the page element in the earlier stage, and when the page identifier of each picture to be displayed is associated with the touch area and the touch response is carried out, the associated touch area is called out only based on the page identifier of the picture to be displayed, so that the occupied time is short.

Step 506: at least one preset data pair is obtained, wherein the data pair comprises a noise threshold value and a preset number/ratio corresponding to the noise threshold value.
One or more groups of preset data pairs of noise thresholds and preset numbers/ratios corresponding to the noise thresholds are predefined, for example, if the noise threshold is 100, the corresponding preset number/ratio is 50%, the noise threshold is 120, and the corresponding preset number/ratio is 40%, specifically, the larger the noise threshold is, the smaller the corresponding preset number/ratio is.
Step 508: and calculating the number/ratio of the sensing areas with the sensing values larger than the noise threshold value in the non-touch area or all the sensing areas, and determining that the data fluctuation exists in the sensing values if the calculated number/ratio of the sensing areas is not smaller than the preset number/ratio corresponding to the noise threshold value in the data pair.
And if the induction values in the non-touch-controllable area or all induction areas meet the corresponding relation of at least one group of preset data pairs, determining that the induction values fluctuate.
If the number/ratio of the sensing areas satisfying that the sensing value in the non-touchable area or the entire sensing area is greater than the noise threshold is not less than 50% at the noise threshold 100, or if the number/ratio of the sensing areas satisfying that the sensing value in the non-touchable area or the entire sensing area is greater than the noise threshold is not less than 40% at the noise threshold 120, determining that data fluctuation exists in the sensing value.
Step 510: and reducing the induction value of the non-touch area to zero, and keeping the maximum induction value in the touch area unchanged.
Keeping the maximum sensing value in the touchable area unchanged as the following formula (1) is executed on the sensing value of the touchable area:
Dataout＝DataMax-(DataMax-Datain)·DataMax/(DataMax-noise threshold) (1)
Wherein the DataMaxIs the maximum induction value in the touch-controllable area, DatainData for obtaining the induction value of the target induction regionoutAnd the induction value of the target induction area output after the second inhibition processing.
By executing the formula (1), the maximum sensing value in the touch area can be kept unchanged, and other sensing values of the touch area are correspondingly inhibited through two parameters, namely the maximum sensing value DataMax and the noise threshold of the touch area, so that the finally output sensing value is close to the sensing value in the normal environment.
