Fig. 1 is that the one kind provided according to embodiments of the present invention is optionally applied to the data correction method of intelligent interaction plate Flow chart, as shown in Figure 1, the method comprising the steps of S102 to step S110:
Step S102, the current signal that the capacitance plate of acquisition intelligent interaction plate generates.
Intelligent interaction plate, also known as interactive intelligent tablet computer, be by touch technology to be shown in display plate (display screen) On content manipulated and realized the integration apparatus of man-machine interactive operation.This integration of equipments projector, electronic whiteboard, The multiple functions of curtain, sound equipment, television set, video conference terminal.
Capacitance-type touch screen technology is worked using the electric current induction of human body.Capacitive touch screen is one piece four layers Compound glass screen, the inner surface and interlayer of glass screen are respectively coated with one layer of ITO, and outermost layer is a thin layer silica protective layer for glass, folder Layer ITO coating is used as working face, and four electrodes are drawn on four angles, and internal layer ITO is shielded layer to guarantee good working environment. When finger touches on the metal layer, due to human body electric field, user and touch screen surface are formed with a coupled capacitor, for height For frequency electric current, capacitor is direct conductor, and then finger siphons away the electric current of a very little from contact point.This electric current is respectively from touching It touches and is flowed out in the electrode on the quadrangle of screen, and the electric current for flowing through this four electrodes is directly proportional at a distance from finger to quadrangle, control Device processed obtains the position of touch point by accurately calculating to this four current ratios.
Capacitive touch screen generally has M+N (M row N column) a physical capacitors touch sensor.This M+N interlaced biographies Sensor constitutes M × N number of capacitive sensing point, and when the finger of user is close to touch screen, capacitor can be changed correspondingly.Sensing Usually in several millimeters or so, this spacing distance determines touch screen at the interval (distance between namely adjacent row or column) of device Physical resolution M × N.
Current signal is carried out analog-to-digital conversion by step S104, obtains the first matrix, the element of the first matrix and capacitance plate Capacitive sensing point has one-to-one relationship.
The quantity for the element that first matrix includes is equal with the quantity of the capacitive sensing of capacitance plate point.Assuming that the electricity of capacitance plate The quantity for holding induction point is M × N, then the quantity for the element that the first matrix includes is also M × N.The i-th row jth arranges in first matrix Element and the capacitive sensing point of the i-th row jth column of capacitance plate there is corresponding relationship, wherein i takes 1 to the natural number between M, j It takes 1 to the natural number between N.
In practical applications, the capacitive sensing point of capacitance plate can reach thousands of up to ten thousand, even more, big due to attached drawing It is small to be limited, in attached drawing part, the case where embodiment of the present invention has illustratively provided 21 × 15 capacitive sensing points.
Step S106, the case where judging whether there is channel abnormal according to the numerical value of element in the first matrix and region are abnormal The case where.
Abnormal as caused by bonding to be divided into two kinds: 1) poor contact causes impedance to change, and partial data is caused to become larger Or become smaller；2) it is fully disconnected, leads to no power, the data on whole vertical or lateral channel is caused to become larger.
For 2) the case where, and be properly termed as channel abnormal.
In the ideal case, the numerical value of the element in the first matrix is equal.For example, Fig. 2 shows a kind of ideal feelings Condition, corresponding first matrix of Fig. 2 are the matrix of 21 rows 15 column, and the numerical value of each element in matrix is 1000.
Fig. 3-1 shows a kind of the case where there are channel abnormals.Corresponding first matrix of Fig. 3-1 is 21 rows 15 column The numerical value of matrix, the 5th column element of matrix is larger, has been more than 1500, and the numerical value of remaining element is all 1000.
The case where judging whether there is channel abnormal according to the numerical value of element in the first matrix, specific method can have more Kind, such as:
The first: judge the target column of the first matrix numerical value whether beyond other column numerical value it is larger, if first The numerical value that the numerical value of the target column of matrix exceeds other column is larger, then can determine the corresponding channel abnormal of target column.For example, In Fig. 3-1, the value of the corresponding element of RX-5 is all larger than 1500, and the value of remaining element of the first matrix is 1000, and RX-5 pairs Numerical value of the value for the element answered beyond remaining column is larger, may thereby determine that the corresponding channel abnormal of RX-5.
Second: it is total to judge that the quantity of element of the numerical value beyond default value in the target column of the first matrix accounts for the column element Whether the ratio of quantity exceeds default ratio, if it was exceeded, the corresponding channel abnormal of target column can be determined.For example, default Ratio can be set to 75%, 80% or 85% etc..Assuming that default value is set as 1300, default ratio is set as 80%, In Fig. 3-1, in the corresponding element of RX-5, the numerical value of all elements has been above 1300, that is, the element beyond default value 1300 Quantity to account for the ratio of the column element total quantity be 100%, be greater than default ratio 80%, hence, it can be determined that RX-5 is corresponding Channel abnormal.
Step S108 the case where if there is channel abnormal, then corrects the abnormal corresponding data in channel.
Optionally, the abnormal corresponding data in channel are corrected, comprising: shield the corresponding data in abnormal channel； Interpolation arithmetic is carried out according to data corresponding with the adjacent plurality of passages in abnormal channel, obtains target data；By target data As the abnormal corresponding data in channel.
Step S110 then corrects the abnormal corresponding data in region if there is the situation of region exception.
In embodiments of the present invention, acquire intelligent interaction plate capacitance plate generate current signal, by current signal into Row analog-to-digital conversion, obtains the first matrix, and the element of the first matrix and the capacitive sensing point of capacitance plate have one-to-one relationship, root The situation of the case where judging whether there is channel abnormal according to the numerical value of element in the first matrix and region exception, if there is channel Abnormal situation then corrects the abnormal corresponding data in channel, if there is the situation of region exception, then to exception The corresponding data in region are corrected, and are solved the fitting of prior art tradition and are applied on large scale capacitance plate, due to touch screen Abnormal problem is touched with caused by display screen gap unevenness between the two and bonding.
The corresponding channel of matrix column is properly termed as vertical passage, and the corresponding channel of the row of matrix is properly termed as laterally logical Road.Judge vertical passage whether Yi Chang method with judge whether Yi Chang method is similar to interconnection.
Assuming that the first matrix is the matrix of M row N column, M and N are natural number, each column of the first matrix and a channel Corresponding, every a line of the first matrix is corresponding with a channel, judges whether there is channel according to the numerical value of element in the first matrix Abnormal situation, specific steps can be with are as follows: determine that numerical value is greater than or equal to the member of the first default value in r column in the first matrix The quantity of element and the ratio of M, obtain the first ratio, r is natural number, 1≤r≤N；Compare the first ratio and the first default ratio Size relation；If the first ratio is less than the first default ratio, it is determined that the corresponding vertical passage of the r column of the first matrix is just Often.
