Embodiment
Understand for convenience the principle of the positional information of the electromagnetic induction array detection time writer touch-control in the present invention, the present invention is CN102163112A by Chinese patent application publication number, denomination of invention is sensor, in the patent application document of double mode touch module and double mode screen touch electronic device, instructions the 6th page [0054] section description and other related content to [0058] section, corresponding Fig. 2 A to Fig. 2 C is introduced in instructions of the present invention to merge the mode of introducing, so that user is arrangement mode and the use principle that electromagnetic induction array in the application is understood in description in CN102163112A patent application document according to above-mentioned Chinese patent application publication number.
Fig. 1 shows the structural representation of the sensor that one embodiment of the invention provides, and as shown in Figure 1, sensor 10 comprises: electromagnetic induction array (as shown in Fig. 1 dotted line frame); Electromagnetic induction array comprises: first direction wire group 11 (as shown in Figure 3A) and second direction wire group 12 (as shown in Figure 2), between the direction of the direction of first direction wire group 11 and second direction wire group 12, there is an angle that is greater than 0 °, and first direction wire group and second direction wire group mutually insulated;
Normally 90 ° of the angles forming between the second direction wire of the first direction wire of first direction wire group and second direction wire group, as shown in Figure 1, this is to adopt Cartesian coordinates to locate the needs of touch point in order to be applicable to great majority.Sometimes in order to adapt to the situation of some special location, for example: adopt polar coordinates to locate touch point, also the first direction wire in can first direction wire group 11 and the second direction wire of second direction wire group 12 mutually intersect formed angle and are set to be greater than 0 °, but are less than 90 °.
Aforesaid first direction wire group 11 is parallel to each other above by two and the first direction wire 110 arranging that insulate forms, and aforesaid second direction wire group 12 is parallel to each other above by two and the second direction wire 120 arranging that insulate forms;
In Fig. 1, arbitrary first direction wire 110 and second direction wire 120 include: the first wire a, the second wire b and connecting line c;
In concrete application, the first wire a is parallel with described the second wire b, and the first wire a is connected in one end of connecting line c, and the second wire b is connected in the other end of connecting line c.Conventionally, first direction wire 110 and second direction wire 120 are U-shaped wire, and the bottom of U-shaped wire can be above-mentioned connecting line c, as shown in Fig. 2 and Fig. 3 A.
Especially, in electromagnetic induction array, the first wire a of first direction wire 110 optional positions of first direction wire group 11 and the second wire b do not repeat/do not overlap to combine unique with adjacent last wire or the combination of a rear wire with the combination of other adjacent two wires in any position;
The first wire a of second direction wire 120 optional positions of second direction wire group 12 and the second wire b do not repeat/do not overlap to combine unique with adjacent last wire or the combination of a rear wire with the combination of other adjacent two wires in any position;
The direction of aforesaid first direction wire group is the direction that the first wire of first direction wire extends, and the direction of second direction wire group is the direction that the first wire of second direction wire extends.
In the present embodiment, will on aforesaid arbitrary connecting line c, all be provided for disconnecting the mode control switch 13 of this connecting line c, the control end of mode control switch 13 connects external control component 20; Conventionally, the control end of the mode control switch 13 of all connecting line c is connected to external control component 20 by pattern control line 130.
When externally all mode control switch 13 of control assembly 20 controls disconnect all connecting line c, in first direction wire group 11 and second direction wire group 12, each self-corresponding first wire a, the second wire b form capacitive coupling touch-control array, now, working sensor receives the touching signals of touch point at capacitive coupling control mode touch mode.Be understandable that, in first direction wire group, the connecting line of all first direction wires all disconnects, and now the first wire of all first direction wires, the second wire are parallel mutually, forms the wire group of a direction of capacitive coupling array; Correspondingly, in second direction wire group, the connecting line of all second direction wires all disconnects, and now the first wire of all second direction wires, the second wire are parallel to each other, and forms the other direction wire group of capacitive coupling array.In practice, processor/external control component can be in arbitrary wire of a direction wire group of capacitive coupling array input pulse signal, if there is this capacitive coupling array of finger touch, processor/external control component is by the be coupled pulse signal of the one or more wires outputs in the other direction wire group of touch-control array of Detection capacitance, the treated positional information of knowing touch point in capacitive coupling touch-control array.
Certainly, when externally control assembly 20 is controlled all mode control switch 13 closure, in first direction wire group 11 and second direction wire group 12, form electromagnetic induction array, so that working sensor is in electromagnetic induction pattern.That is to say, when in first direction wire group, all mode control switch 13 is closed, first direction wire can be equivalent to the first direction wire of electromagnetic induction array of the prior art, for example U-shaped wire; Correspondingly, when in second direction wire group, all mode control switch 13 is closed, second direction wire can be equivalent to the second direction wire of electromagnetic induction array of the prior art, as U-shaped wire, therefore, first direction wire group and second direction wire group form electromagnetic induction array, sensor now can receive the touch-control of time writer, so that processor/external control component detects the alternating electromagnetism signal of first direction wire and the output of second direction wire, with the positional information of touch point in processing and identification electromagnetic induction array.
Be understandable that, in the present embodiment, when in electromagnetic induction array, all connecting line c all disconnect, capacitive coupling touch-control array can be equivalent to aerial array of the prior art, in the present invention by mode control switch being set on the connecting line at existing electromagnetic induction array, can make sensor adopt and both realize electromagnetic induction pattern with an array, can also realize capacitive coupling control mode touch mode simultaneously.
