Abstract
The invention provides a sensor component, a cover plate component and a mobile terminal. The sensor component comprises a first light emitter and a first light receiver, wherein the first light emitter is used for emitting a first ray of which the polarization direction is a first polarization direction, and the first ray forms a first reflection ray after being reflected by an obstacle; and the first light receiver is used for receiving the first reflection ray and filtering out rays of which the polarization direction is not the first polarization direction. Because the first ray and the first reflection ray are linearly polarized lights with the first polarization direction, and the first light receiver only can receive the rays with the first polarization direction, rays emitted by other light emitters can be prevented from interfering the first light receiver, thus being beneficial to improving sensitivity and accuracy of detection.

For example, the absorbance of the first adhesive layer 322 can be 80% or more than 80%, the absorbance of the second adhesive layer 323
Can be 10% or less than 10%.In practical application, the first adhesive layer 322 can be referred to as transmission layer, for through most of
Signal.Second adhesive layer 323 can be referred to as barrier bed, for blocking most of signal.
In practical application, the second adhesive layer 323 is used for hiding the internal structure of mobile terminal 1, so that from cover board body
Mobile terminal 1 internal structure cannot be seen in 321 outsides, to realize the aesthetic of the globality of mobile terminal 1.
Wherein, the first adhesive layer 322 can be white ink layer, and the second adhesive layer 323 can be black ink layer.When
So, white ink layer and black ink layer are only for example, and first adhesive layer 322 and the second adhesive layer 323 can also be according to not
Same aesthetic requirements are designed to other colors, as long as the absorbance of first adhesive layer 322 is saturating more than second adhesive layer 323
Penetrate rate.Wherein, the ink layer of white ink layer, black ink layer or other colors can be by spraying or typography
To make.
It is monolayer or multilamellar that first adhesive layer 322 is the multilamellar, second adhesive layer 323.For example, the first adhesive layer 322 is wrapped
Three sublayers 3221 are included, three sublayers 3221 are overlapped successively.
Or, such as shown in Fig. 6, the first adhesive layer 322 can be monolayer, and the second adhesive layer 323 is monolayer.
Fig. 2 and Fig. 3 is continued referring to, the second adhesive layer 323 can include first area 323A and second area 323B.
First area 323A can be understood as the part that second adhesive layer 323 is overlapped each other with first adhesive layer 322, and this second
Region 323B can be understood as second adhesive layer 323 and the underlapped part of first adhesive layer 321.First area 323A's
Absorbance of the absorbance more than second area 323B, so that signal can pass through first area 323A, the first adhesive layer successively
322nd, cover board body 321, and successively through cover board body 321, the first adhesive layer 322 and the after reflecting through outer barrier 70
One region 323A.
Wherein, the first adhesive layer 32 covers the first area 323A of the second adhesive layer 323, so that from mobile terminal 1
First area 323A cannot see in portion.
In certain embodiments, when the second adhesive layer 323 is black ink layer, can be to the black of first area 323A
Ink carries out being processed so that the absorbance of the absorbance more than second area 323B in the region.
In certain embodiments, the through hole that first area 323A can go out for the boundary definition of second area 323B, this
When the region absorbance be 100%, the first adhesive layer 322 cover the through hole.In certain embodiments, can be in first area
In the through hole of 323A, filling is available for the material of signal transmission.
In certain embodiments, first area 323A includes the first subregion 3231A and the second subregion 3232A.
For example in the figure 7, first subregion 3231A and first optical transmitting set 311, the first light receiving area 312 and
Second optical transmitting set 315 is relative, second subregion 3232A and second optical receiver 316 and the ambient light sensor 316
Relative.The first subregion 3231A and the second subregion 3232A was respectively by leading to that the boundary definition of second area 323B goes out
Hole.
For example in fig. 8, first subregion 3231A and first optical transmitting set 311, the first light receiving area 312 with
And second light receiving area 316 is relative, second subregion 3232A and second optical transmitting set 316 and ambient light sensor
313 is relative.The first subregion 3231A and the second subregion 3232A is respectively to be gone out by the boundary definition of second area 323B
Through hole.
During work, circuit board 314 controls the first optical transmitting set 311 to send the first light, the polarization direction of first light
For the first polarization direction；Circuit board 314 controls the second optical transmitting set 315 to send the second light, the polarization direction of second light
For the second polarization direction；Circuit board 314 obtains the first photoelectricity of the first reflection light that first optical receiver 312 is received
Conversion value, first reflection light is reflected to form through obstacle by first light；Circuit board 314 obtains second light
Second opto-electronic conversion value of the second reflection light that receptor is received, second reflection light is by second light through resistance
Block material 70 is reflected to form；Circuit board 314 judges current mobile according to the first opto-electronic conversion value and the first opto-electronic conversion value
Terminal 1 is with respect to the relative position of the obstacle 70；When the first opto-electronic conversion value be located at first be close to interval when or the second light
When electric conversion value is located at the second close interval, judge that current mobile terminal is close to obstacle；When the first opto-electronic conversion value is located at the
One away from interval when, and the second opto-electronic conversion value be located at second away from interval when, judge current mobile terminal 1 away from the stop
Thing 70.The interference of other light so as to realize the detection close to or away from state, can be avoided, with improve detection sensitivity with
And the beneficial effect of accuracy.
In addition, the face for controlling mobile terminal 1 close to or away from state that the circuit board 314 can also be detected according to this
The bright screen of the such as touching display screen of plate 20 or screen is put out, such as, when detecting the mobile terminal obstacle 70 being close to, control the face
Plate 20 puts out screen, when the mobile terminal 1 is detected away from the obstacle 70, controls 20 bright screen of panel.
