Embodiment 1：
The embodiment of the present invention provides a kind of contactor control device 1.Fig. 2 is the top view of contactor control device 1 provided by the invention.With reference to
Fig. 2, light shield layer 20, the light shield layer 20 are arranged on the frame region in the touch surface of the transparent touch panel 10, and the screening
There is light hole 201 on photosphere 20.It should be noted that the light shield layer 20 is close to the edge of transmission region to transparent touch panel
The distance at 10 edge can be identical.The light hole 201 can be the circle or other shapes shown in Fig. 2,
It is not limited thereto.In addition, the region in the transparent touch panel 10 in addition to the light shield layer 20 can be touching for contactor control device 1
Control region 101.
Fig. 3 is the AA of the contactor control device 1 shown in Fig. 2 to sectional view.As shown in figure 3, the contactor control device 1 includes：It is transparent
Touch pad 10, light shield layer 20 and optical transceiving device.
Wherein, as shown in Figure 3 a, the transparent touch panel 10 includes：Touch surface 101 and non-tactile face 102.It is described transparent
The material of touch pad can be glass.
Light shield layer 20 is arranged on the frame region in the touch surface 101 of the transparent touch panel 10, and the light shield layer 20
It is upper that there is light hole 201.
As shown in figure 3, the optical transceiving device is arranged on the non-tactile face 102 of the transparent touch panel 10.The light
Transceiving device includes：The first transmitting terminal 30 and the first receiving terminal 40 being correspondingly arranged with the light hole 201, and positioned at described
The second receiving terminal 50 where first transmitting terminal on the opposite side on side.Described here being correspondingly arranged with light hole 201 is exactly by
One transmitting terminal 30 and the first receiving terminal 40 are arranged on corresponding with the light hole 201 on the non-tactile face of the transparent touch panel 10
Region, but the first transmitting terminal 30 and the first receiving terminal 40 are not utterly limited in region corresponding with the light hole
It is interior, it can be determined according to the size of the first transmitting terminal 30 and the first receiving terminal 40, as long as the embodiment of the present invention can be met
The requirement of middle light transmission.
It should be noted that first receiving terminal 40 is used to receive the first transmitting end-fire 30 to the transparent touch
The region of light hole 201 of plate 10 and the light being emitted back towards via the transparent touch panel 10, second receiving terminal 50 are used to receive
Simultaneously it is all-trans in the transparent touch panel 10 touch area of transparent touch panel 10 described in the directive of first transmitting terminal 30

The sign Index at family.Contactor control device shown in Fig. 3 or Fig. 4 can detect to user's sign Index.
In the specific implementation, during touch-control, the first transmitting terminal 30 can be without work.What first transmitting terminal 30 was sent enters
When firing angle C meets arcsinC >=1n/, as shown in fig. 6, light is totally reflected in touch pad 10,50 terminations are received by second
Receive.When there is finger (or other pointers) contact on touch pad 10, the refractive index of the touch place of touch pad 10 changes, and first
What transmitting terminal 30 was sent meets that some light of total reflection condition projects from the finger touch place of touch pad 10, therefore the second receiving terminal
The intensity of 50 light received can die down.Generally, multiple first transmitting terminals and multiple institutes are provided with contactor control device
The second receiving terminal is stated, when finger contacts touch pad 10, the light intensity that at least two the second receiving terminals receive dies down, in basis
Transmitting terminal corresponding at least two second receiving terminal is assured that out at least two light paths, at least two light paths by described in
Intersection point be defined as touch point.
Generally, it is to use wavelength as 660nm feux rouges and 940nm infrared light, it is right according to oxyhemoglobin (Hb02)
660nm red light absorption amounts are less, more to 940nm infrared Absorption amounts.Hemoglobin (Hb) to 660nm red light absorptions amount compared with
It is more, it is less to 940nm infrared Absorption amounts.With the ratio of spectrophotometry infrared Absorption amount and red light absorption amount, just
It can determine that the degree of oxygenation of hemoglobin.
Contactor control device shown in Fig. 3 or Fig. 4 can detect to user's sign Index, specifically include：
As shown in figure 8, when carrying out user's sign Indexs measure, the light (such as infrared light) that the first transmitting terminal 30 is sent is penetrated
Reflected after entering light hole 201 by user's finger, the light reflected is received by the first receiving terminal 40.Data processing module is carried out
Data acquisition, then the data to collecting handle the heart rate that can measure user.
As shown in figure 9, when carrying out blood oxygen/heart rate test, light (such as infrared light) that the first transmitting terminal 30 is sent, second
The light (such as feux rouges) that transmitting terminal 60 is sent is reflected after injecting light hole 201 by user's finger, and the light reflected is by first
Receiving terminal 40 receives.Data processing module carries out data acquisition, then the data to collecting are handled.Specifically, will detect
To by finger arteries reflect feux rouges and infrared light be converted into electric signal.Due to skin, muscle, fat, vein
Blood, pigment and bone etc. be to the absorption coefficient of both light it is constant, Hb02 and Hb concentration only in artery blood flow with
The artery of blood periodically changes, so as to cause the signal intensity cyclically-varying therewith that photoelectric detector exports, by these
Periodically variable signal is handled, so that it may measures the blood oxygen saturation of user.
