The position of touch that can determine touch control operation through the above configuration, since the present disclosure embodies by plane
The mode of three-axis reference determines position of touch, can be adapted for touch panel of various shapes, relative to traditional direct
The mode of reference axis, and do not need to execute horizontal and vertical not full operation, to save circuit design, reduce corresponding
Cost.
Further, due to can usually be introduced into noise and add u, v, w coordinate value in position of touch in actual use
With and be unsatisfactory for the condition of u+v+w=0, therefore, in the embodiment of the present disclosure further increase the accuracy of position of touch, can
It is optimized so that triaxial coordinate value is converted into rectangular co-ordinate value.Wherein it is possible to by the triaxial coordinate value of determining position of touch
In three values (u, v and w) combination of two respectively, the x value and y value being converted into rectangular coordinate system obtain three groups of x values and y value,
The mean value based on three groups of x values and y value determines the coordinate value of the position of touch under rectangular coordinate system again, so as to further mention
High position accuracy.For example, the u value and v value that can be based respectively in triaxial coordinate value determine first group of x value and y value, it is based on three axis
U value and w value in coordinate value determine second group of x value and y value, and based in triaxial coordinate value v value and w value determine third group
X value and y value, then take mean value to obtain three groups of x valuesMean value is taken to obtain three groups of y values againIt utilizesWithObtain rectangular co-ordinate
The coordinate value of position of touch under system.
The above is only based on each electrode in touch-control selection region capacitance change and weight determine the one of position of touch
A example, the disclosure determine the concrete mode of position of touch with no restrictions to determining weight and based on weight.

The location information of pole.
Fig. 5 shows the structural schematic diagram of the three-axis reference of the touch panel according to the embodiment of the present disclosure, wherein three axis are sat
Three reference axis u axis, v axis and the w axis of mark system are respectively set in the same plane, and the angle between every two week is 120
Degree, the center of above-mentioned first electrode can be the center of circle of the three-axis reference.Statement for convenience can define rectangular hang down
Straight reference axis is x-axis and y-axis respectively, and the vertical coordinate axle of corresponding regular hexagon is also x-axis and y-axis, and every the angle of 2 π/3
Degree is just distributed u axis, v axis and w axis, and wherein w axis is contrary with y-axis.Wherein the x-axis in rectangular coordinate system and y-axis can be with three
U axis, v axis in axis coordinate system and progress coordinate conversion between w axis, and since u axis, v axis and w axis are put down in two-dimensional surface
The triaxial coordinate being distributed, so the coordinate value of effective regular hexagon all meets u+v+w=0, i.e. seat in three reference axis
Scale value adduction is zero.
Data processing module 4 can obtain position of each electrode in above-mentioned three-axis reference in electrode layer 2, example respectively
It can such as determine location information of the electrode centers in three-axis reference.Further, data processing module 4 can be based on determination
Touch-control selection region in projector distance of the center in each reference axis in three-axis reference of each electrode determine the electrode
Weight on respective coordinates axis；And for each reference axis, the capacitance change and the electrode for calculating each electrode are in the seat
The sum of products of weight on parameter, and calculate this and with the ratio between the sum of the capacitor of each electrode in the touch-control selection region
Value, and the position coordinates that touch point is determined corresponding to the ratio of each reference axis can be based further on.

With and be unsatisfactory for the condition of u+v+w=0, therefore, in the embodiment of the present disclosure further increase the accuracy of position of touch, can
It is optimized so that triaxial coordinate value is converted into rectangular co-ordinate value.Wherein it is possible to by the triaxial coordinate value of determining position of touch
In three values (u, v and w) combination of two respectively, the x value and y value being converted into rectangular coordinate system obtain three groups of x values and y value,
The mean value based on three groups of x values and y value determines the coordinate value of the position of touch under rectangular coordinate system again, so as to further mention
High position accuracy.For example, the u value and v value that can be based respectively in triaxial coordinate value determine first group of x value and y value, it is based on three axis
U value and w value in coordinate value determine second group of x value and y value, and based in triaxial coordinate value v value and w value determine third group
X value and y value, then take mean value to obtain three groups of x valuesMean value is taken to obtain three groups of y values againIt utilizesWithObtain rectangular co-ordinate
