Description

False touch recognition method for foldable touch display device, foldable touch display device and information processing device

The present invention relates to the technical field of foldable touch display devices, in particular to a method for identifying false touches on overlapping screens of foldable touch display devices.

It is known that touch display devices are one of the indispensable components in mobile electronic devices such as tablet computers, smart phones, all-in-one computers, and smart watches. As the sales growth of large-sized smart phones with high screen ratio slows down, the emergence of foldable smart phones has subverted the traditional smart phone type. It should be known that when the foldable smart phone is folded, the two touch display screens of the foldable smart phone are closely attached to each other in a screen-to-screen manner. However, the folding method of the above-mentioned foldable smart phone will cause false touch mode on the touch display screen.

When the touch function is normally executed, the control circuit will first collect a frame of non-touch raw data (RawData) from a plurality of touch sensors (ie, capacitors) integrated in the touch display screen and process it into a Frame non-touch basic data (BaseData), then collect multiple frames of touch detection data from the plurality of touch sensors in a timely manner, and then calculate the difference data between the non-touch basic data and each frame of touch detection data , to obtain the touch sensing value after data processing. In order to ensure touch sensitivity and touch accuracy, the control circuit will collect a frame of non-touch raw data (RawData) immediately after the screen is turned on. After performing a difference operation on the non-touch basic data to obtain a frame of difference data (DifData), the control circuit uses a corresponding algorithm to compensate and correct the non-touch basic data.

However, for foldable smartphones, there will be some problems when compensating the non-touch basic data according to the existing algorithms. FIG. 1 shows a table diagram of a frame difference data measured in a folded state of a conventional foldable smart phone. As shown in Figure 1, when the two touch display screens approach each other in a screen-to-screen manner without turning off the power of the screens, the value of the raw touch detection data (RawData) collected by the control circuit will be larger. As a result, the difference data map (DifData map) obtained by performing a difference operation on the non-touch basic data and the touch detection raw data will have a large area of numerical bulges. It is worth noting that when the foldable smart phone is continuously maintained in the folded state, the control circuit will use an algorithm to compensate the basic data without touch until the difference data map (that is, full screen ) of each difference data are close to or equal to 0.

FIG. 2 shows a table diagram of a frame difference data measured by a conventional foldable smart phone in a continuously folded state. When the two touch display screens are close to each other in a screen-to-screen manner without turning off the power of the screens, the foldable smart phone is kept in a folded state. Comparing Figure 1 and Figure 2, it can be found that when the foldable smart phone is in a continuously folded state, the control circuit obtains the value obtained by performing a difference operation on the non-touch basic data and the touch detection raw data The difference data map (DifData map) will become more and more messy.

FIG. 3 shows a table diagram of a frame difference data measured when a conventional foldable smart phone is switched from a folded state to a screen raised state. As shown in Figure 3, since the control circuit will continuously use the algorithm to compensate the non-touch basic data when the foldable smart phone is kept in the folded state, the tracking compensation for the non-touch basic data will lead to When the foldable smart phone is switched to the screen-raised state, a large area of negative value blocks appears in the difference data map, forming a so-called negative capacitance data block. In this case, when the user performs at least one touch operation on any touch display screen, the touch display screen will not perform a corresponding action according to the touch operation. Therefore, it is necessary to enable the control circuit to recognize the above-mentioned situation, to ensure that the non-touch basic data returns to normal after the screen is lifted, without affecting the recognition of normal touch operations by the touch display screen.

It can be seen from the above description that there is an urgent need in the art for a new method for identifying false touches on overlapping screens for foldable touch display devices.

FIG. 4 shows a flow chart of a method for identifying false touches on overlapping screens disclosed by the present invention for a foldable touch display device. The method of the present invention is applied to an electronic device with a foldable touch display device, and is executed by a control circuit included in the foldable touch display device, so as to identify whether the foldable touch display device is in A folded state or a screen raised state. In a feasible embodiment, the control circuit is included in an electronic chip, and the electronic chip is selected from a touch and display driver integration (Touch and Display Driver Integration, TDDI) chip and a touch detection chip. Make up any one of the groups. To explain in more detail, when the foldable touch display device is in the collapsed state, the control circuit executes an identification program for the false touch range of the stacked screen, so that after determining the false touch range of the stacked screen, the stacked screen will not be detected. Data compensation is performed on the non-touch reference data in the false touch range, so as to ensure that when the user performs at least one touch operation on any touch display screen, the touch display screen will still operate according to the touch operation. Take corresponding action. Further, when the foldable touch display device is in the screen-up state, the control circuit restarts the data compensation for the non-touch reference data.

As shown in FIG. 4 , the method for identifying false touches on folded screens of a foldable touch display device according to the present invention firstly executes step S1: performing a screen folding (Cover down) identification on a frame of first difference data (DifData) program, so as to identify at least one stack of screen false touch ranges in the first difference data of the frame; wherein, the first difference data of the frame is through the first non-touch detection raw data (RawData) of a frame and a The frame non-touch reference data (BaseData) is obtained by performing a difference operation.

When performing the screen folding (Cover down) recognition program, first, after confirming that one of the maximum difference data (DifMax) of the first difference data of the frame is greater than a maximum threshold (DifHi _th ), the first difference data of the frame is In the case where each of the first difference data among the value data simultaneously satisfies a first inequality Dif(i,2)-Dif(i,1)>TH1 and a second inequality Dif(i,2)>TH2 , calculating a first count of all the first difference data satisfying the condition. In the screen folding recognition program, Dif(i, j) is a variable used to represent the first difference data, i∈{1, 2} and j∈{1, ColMax}. Moreover, TH1 is a first set threshold, and TH2 is a second set threshold.

Next, after confirming that the first count is greater than a count threshold (CounterTH), each of the first difference data simultaneously satisfies a third inequality Dif(i, ColMax-1)-Dif(i, ColMax )>TH1 and a fourth inequality Dif(i, ColMax)>TH2, calculate a second count of all the first difference data Dif(i,j) satisfying the condition. Among them, ColMax is the coordinate of the maximum value of one of the plurality of row difference data in the first difference data of the frame, and RowMax is the maximum value of one of the plurality of column difference data in the first difference data of the frame The coordinates. Then, after confirming that the second counting amount is greater than the counting threshold, each of the first difference data simultaneously satisfies a fifth inequality Dif(2,j)-Dif(1,j)>TH1 and a In the case of the sixth inequality Dif(2,j)>TH2, calculate a third count of all the first difference data satisfying the condition.

Continuing, after confirming that the third counting amount is greater than the counting threshold value, each of the first difference data simultaneously satisfies a seventh inequality Dif(RowMax-1,j)-Dif(RowMax,j)> In the case of TH1 and an eighth inequality Dif(RowMax-1,j)>TH2, calculate a fourth count of all the first difference data satisfying the condition. Next, after confirming that the fourth count is greater than the count threshold, after judging that the first count, the second count, the third count, and the fourth count satisfy one of a plurality of inequalities In the case of , the first difference data of the frame is determined as a valid frame. In one embodiment, the plurality of inequalities include:

Counter1∈(CounterTH,RowMax) (1)

Counter2∈(CounterTH,RowMax) (2)

Counter3∈(CounterTH,ColMax) (3)

Counter4∈(CounterTH,ColMax) (4)

Among them, Counter1 is a variable used to represent the first count, Counter2 is a variable used to represent the second count, Counter3 is a variable used to represent the third count, and Counter4 is used to represent the fourth count The variable of the quantity, and CounterTH is the counting threshold.

Next, when a continuous frame number of the effective frames is greater than a first continuous frame number threshold value, it is recognized that the foldable touch display device is in the screen folded state, and at the same time, a false touch of a stack of screens is marked The plurality of false touch coordinates corresponding to each of the difference data within the range (let trace be marked as 1).

After the determination of the false touch range of the stacked screen is completed, as shown in FIG. 4 , the method flow proceeds to step S2: when it is recognized that the foldable touch display device is in a folded state of the screen, stop checking the screen in the frame. A data compensation is performed on a plurality of non-touch reference data (BaseData) located within the overlapping screen false touch range. Simply put, for a foldable touch display device including two touch display screens, when the two touch display screens are close to each other in a screen-to-screen manner without turning off the power of the screens, the control The touch detection raw data map (RawData map) collected by the circuit will include at least one stacked screen false touch range, and the value of the touch detection raw data within the stacked screen false touch range will be large, resulting in the A difference value map (DifData map) obtained by performing a difference operation on the touch basic data and the touch detection raw data will have a large area of numerical protrusions.

Therefore, the method of the present invention uses step S1 to find out at least one false touch range of stacked screens, and then uses step S2 to stop detecting any false touches in the frame when it is identified that the foldable touch display device is in a folded state. A data compensation is performed on the plurality of non-touch reference data corresponding to the plurality of false touch coordinates among the touch reference data (BaseData). At this time, when a touch area of the touch panel of the touch display screen is identified as the occurrence of the false touch of the overlapping screen, the control circuit will stop the data compensation to realize that the overlapping has occurred. The touch area where the screen is accidentally touched is redefined as an untouched area.

FIG. 5 shows a table diagram of a frame difference data measured when a foldable touch display device is switched from a folded state to a screen raised state. As shown in FIG. 5 , in the case of applying the false touch recognition method for foldable screens of the present invention for a foldable touch display device, even if the control circuit is sensitive to the collected touch detection raw data (RawData) and the originally stored A difference operation is performed on the touch base data (BaseData) to obtain a difference data map (DifData map), and the difference data map does not have at least one region with a value bulge.

As shown in FIG. 4 , the method flow then executes step S3: executing a screen lifting recognition program on a frame of second difference data (DifData), wherein the frame of second difference data is obtained by performing a second non-touch operation on a frame. The detection raw data (RawData) and the non-touch reference data (BaseData) of the frame are obtained by performing a difference operation. It should be understood that, based on the principle of time-sharing data collection, the first difference data of one frame in the step S1 and the second difference data of one frame in the step S3 refer to the data collected by different frame numbers. Difference data (DifData). Therefore, the first difference data and the second difference data are represented by the same variable DifData in the algorithm.

In one embodiment, the cover up recognition procedure includes a plurality of steps. First, when the first counting quantity satisfies a first set operation formula Counter1∈(CounterTH, RowMax), the second counting quantity satisfies a second set computing formula Counter2∈(CounterTH, RowMax), and the third counting quantity satisfies a In the case of the third set calculation formula Counter3∈(CounterTH, ColMax) and the fourth counting quantity satisfying a fourth set calculation formula Counter4∈(CounterTH, ColMax), the second difference data of the frame is determined as a valid frame . Among them, Counter1 is a variable used to represent the first count, Counter2 is a variable used to represent the second count, Counter3 is a variable used to represent the third count, and Counter4 is used to represent the fourth count The variable of the quantity, and CounterTH is the counting threshold. Next, when a continuous frame number of the effective frames is greater than two first continuous frame number thresholds, it is identified that the foldable touch display device is in the screen-up state.

After step S3 is completed, as shown in FIG. 4 , the method flow proceeds to step S4: when it is recognized that the foldable touch display device is in a state of raising the screen, enable the frame without touch reference data. data compensation. It is supplemented that, after completing the screen lift recognition program to identify that the foldable touch display device is in the screen lift state, the control circuit restarts the data compensation for the frame of non-touch reference data The mark of the false touch coordinates of each said false touch coordinates must be cleared first.
