It is not limited to ring-type shown in Fig. 2 B with the shape of induction coil A2, can also be arbitrary closing/semiclosed shape, as long as
Sensing magnetic fields region can be built up.And should be noted that above-mentioned example is only for illustrating technology of the invention, rather than to limit
The system present invention.The quantity that magnetic strength shown in Fig. 2A and Fig. 2 B surveys the quantity of mould group, position and magnetic sensing unit all can foundation
The difference of actual product and adjust, be not limited thereto.
Fig. 3 is that the magnetic strength of another embodiment according to the present invention surveys the function block schematic diagram of mould group 104.In this embodiment
In, it includes N number of (N is positive integer) magnetic sensing unit 304-1~304-N that magnetic strength, which surveys mould group 104,.Further, each magnetic strength is surveyed single
First 304-1~304-N is, for example, Hall effect magnetic measuring sensor.
Magnetic sensing unit 304-1~304-N is by power supply VDDPower supply, the size of magnetic flux change is converted into analogy news
Number output.As shown in figure 3, magnetic sensing unit 304-1~304-N can respond magnetic flux change and accordingly output voltage news respectively
Number Vout1~VoutN, and voltage signal Vout1~VoutNIt can be considered more sensing signals SS shown in FIG. 1.It needs to illustrate
It is, when not detecting operation object (such as finger), voltage signal that each magnetic sensing unit 304-1~304-N is exported
Vout1~VoutNFor known preset voltage value.For example, Vout1=V01, Vout2=V02..., VoutN=V0N.Wherein V01~
V0NFor preset voltage value, and these preset voltage values V01~V0NCan be identical or different, specifically by designer according to practical feelings
Depending on condition.
For convenience of description, it is assumed that each preset voltage value V01~V0NAll it is equal to V0, by taking magnetic sensing unit 304-1 as an example, work as behaviour
When entering sensing area (in the sensing coil) of magnetic sensing unit 304-1 as object, because magnetic flux changes, magnetic sensing unit
Voltage signal V caused by 304-1out1It will be from preset voltage value V0Become V0+ΔV1.Similarly, when operation object enters magnetic strength
When surveying the sensing area of unit 304-2, voltage signal V caused by magnetic sensing unit 304-2out2It will become V0+ΔV2, with such
It pushes away, when operation object enters the sensing area of magnetic sensing unit 304-N, voltage signal caused by magnetic sensing unit 304-N
VoutNIt will become V0+ΔVN.Wherein, Δ V1~Δ VNRefer to output voltage variable quantity.
Controller 106 can be according to voltage signal Vout1~VoutNDecide whether to trigger the threshold values V that interface operatesTH.In this reality
It applies in example, it can be according to voltage signal Vout1~VoutNAverage value EV determine threshold values VTH:
VTH=(EV-V0)*K
Wherein COEFFICIENT K is constant, such as 3/4, but also arbitrary number.
Determining threshold values VTHAfterwards, as each voltage signal Vout1~VoutNAll it is greater than threshold values VTH, that is, can determine whether that magnetic strength surveys mould group
Control key function corresponding to 104 is triggered, and controller 106 will generate corresponding control signal CS to control user's interface UI
Operation.Conversely, if each voltage signal Vout1~VoutNIn only portion voltage signal be greater than threshold values VTH, then can determine whether that magnetic strength is surveyed
Control key function corresponding to mould group 104 is not triggered.Therefore, threshold values V can be controlled by taking appropriate COEFFICIENT KTHSize, with
It avoids false triggering or is not easy the case where triggering key generation.
The present invention more proposes a kind of operating method of display device 100, and operating method is the following steps are included: pass through display mould
102 display user's interface UI of group；Mould group 104 is surveyed by magnetic strength, user is responded and operates the magnetic flux change generated, with output
One or more sensing signal SS；By controller 106, control signal CS is generated according to one or more sensing signal SS, with
Control the operation of user's interface UI.
In conclusion the display device and its operating method of contactless operation proposed by the invention, user can be
In the case where not touching physical button, the operation of user's interface is triggered by electromagnetic induction mechanism.Therefore, of the invention non-to connect
The display device of touch operation compares traditional monitor and is particularly suited for medical display device, to reduce medical infection risk.Separately
Outside, since user is not required to pressing physical button to operate, therefore it can avoid the loss of physical button, and then extend equipment
Service life.
The present invention is described by above-mentioned related embodiment, however above-described embodiment is only to implement example of the invention.
It must be noted that the embodiment disclosed is not limiting as the scope of the present invention.On the contrary, do not depart from spirit of the invention and
It is changed and retouched made by range, belongs to scope of patent protection of the invention.
