Step 4：When under touch-control input pattern and when receiving electromagnetic induction signal, then microprocessor switches to electromagnetic induction
Pattern, untill the reception of electromagnetic induction signal is completed, and switches back into touch-control input pattern；And
Step 5：After touch-control input pattern completes to receive touch control input signal, then electromagnetic induction pattern is performed.
The digiboard 100 of the present invention is changeable in electromagnetic induction pattern and touch-control input pattern, digital in different modes
Plate has corresponding signal reception processing.
First, when digiboard 100 comes into operation, digiboard 100 can drive electromagnetic induction module 120 to be connected to induction coil
Group 110 simultaneously performs electromagnetic induction pattern（Correspondence step 1）.When digiboard 100 enters electromagnetic induction pattern, microprocessor 140
Electromagnetic induction signal when time writer is moved can be received by induction coil group 110 and electromagnetic induction module 120.
When microprocessor 140 performs electromagnetic induction pattern, microprocessor 140 can be continued in the way of first circulation Loop1
Detect the presence of electromagnetic induction signal input.If microprocessor 140 during first circulation Loop1 in detected electromagnetism sense
When induction signal is inputted, microprocessor 140 understands counting first circulation Loop1 again and detects the presence of electromagnetic induction signal input.
That is, microprocessor 140 is whenever new electromagnetic induction signal is detected, microprocessor 140 will accent start timing,
And detected in new first circulation Loop1 either with or without electromagnetic induction signal.Microprocessor 140 connects in first circulation Loop1
If receiving electromagnetic induction signal, what digiboard 100 can continue maintains electromagnetic induction pattern.
If microprocessor 140 during first circulation Loop1 in do not detected electromagnetic induction signal input, it is micro-
Processor 140 can exit electromagnetic induction pattern, and perform touch-control input pattern（Correspondence step 2）.Wherein, first circulation Loop1
Time span can be determined according to the area of digiboard 100 or the quantity of signal wire.
Under touch-control input pattern, microprocessor 140 sequentially induction coil group 110 is connected to touch control input module
130 or any of electromagnetic induction module 120.Microprocessor 140 with second circulation Loop2 during in detect the presence of touch-control input
Signal or electromagnetic induction signal.The digiboard 100 of the present invention first can connect touch control input module 130 in touch-control input pattern
In induction coil group 110.Then, induction coil group 110 can be switched to electromagnetic induction module 120 by microprocessor 140.Namely

Electromagnetic induction signal.If not receiving more than first circulation Loop1 and new electromagnetic induction signal, then microprocessor 140
Then reenter electromagnetic induction pattern.When user carries out touch-control with finger, if simultaneously with time writer close to digiboard 100,
The electromagnetic induction signal of the meeting preferential receipt time writer of digiboard 100.Consequently, it is possible to which can reduce digiboard 100 is using electromagnetism
Finger is to the Position disturbance of time writer during pen, and can be used as anti-palm false touch（Palm rejection）Anti-tampering mechanism.
In second circulation Loop2 in addition to above-mentioned function mode, the present invention can also have following change aspect.Second
If receiving electromagnetic induction signal during circulation Loop2, then microprocessor 140 can be held in the way of first circulation Loop1
It is continuous to detect whether also electromagnetic induction signal.Microprocessor 140 is while first circulation Loop1 is switched to, microprocessor 140
Also second circulation Loop2 remaining time can be recorded.If microprocessor 140 is not received by after first circulation Loop1
New electromagnetic induction signal, then microprocessor 140 will return to second circulation Loop2 subsequent treatment, continue to detect that touch-control is defeated
Enter signal.Implement from foregoing unlike aspect, microprocessor 140 is after first circulation Loop1 has been performed in this implementation aspect
The unfinished states of second circulation Loop2 can be returned to and continued executing with.
The detection of digiboard and its input signal according to disclosed by the embodiments of the present invention and switching method, due to
The material of one direction signal line and second direction signal wire is graphene, and because the impedance of graphene is relatively low, thus be adapted to
Using in the touch control display with double use patterns.Due to first direction signal wire and second direction signal wire resistance compared with
It is low, thus the charging signals that are provided of charging antenna are less susceptible to be shielded by first direction signal wire and second direction signal wire, enter
And with stronger signal intensity.Therefore, solving tin indium oxide impedance in the prior art needs improvement, without being adapted for use with
The problem of touch control display.
Further, since digiboard is come while the input for receiving time writer and finger is believed by single induction coil group
Number.Therefore, element, manufacturing cost and the maintenance cost set needed for two kinds of different input modes can also be reduced.
Certainly, the present invention can also have other various embodiments, ripe in the case of without departing substantially from spirit of the invention and its essence
Various corresponding changes and deformation, but these corresponding changes and change ought can be made according to the present invention by knowing those skilled in the art
Shape should all belong to the protection domain of appended claims of the invention.
