In some way of example, ambient light sensor 40 can share a regional transmission with signal receiver 32.

Preferably, regional transmission can be through hole, such as the described regional transmission 181 of first regional transmission 180 and/or second For through hole.It will be introduced below so that regional transmission is through hole as an example.

So that signal is optical signal as an example, for the purposes of meeting light sensitive device (such as proximity transducer 30 and ambient light sensor 40) demand of transmitting-receiving optical signal, the black-out ink layer 18 is also needed to set three holes, and a hole is launched for signal projector 31 Optical signal a, hole receives the optical signal that signal projector 31 is sent for signal receiver 32, and a hole supplies ambient light sensor 40 induced environment optical signals.

As shown in Figs. 8 to 11, the black-out ink layer 18 is provided with through hole 180 (i.e. the first regional transmission), first through hole 181 (i.e. the second regional transmission) and the second through hole 182 (i.e. the 3rd regional transmission).Wherein, signal projector 31 is located at through hole 180 Lower section, optical signal is outwardly launched by the through hole 180；Signal receiver 32 is located at the lower section of first through hole 181, by this first Through hole 181 receives the optical signal that signal projector 31 is launched；Ambient light sensor 40 is located at the lower section of the second through hole 182, by this Second through hole 182 senses external environment optical signal.

In some embodiments, made to simplify terminal, signal receiver 32 and ambient light sensor 40 can be total to With a hole, with reference to Figure 12, the ambient light sensor 40 and signal receiver 32 are located at the lower section of through hole 183, share through hole 183.

Through hole 180 and first through hole 181 are hidden in the covering of clear ink layer 170.It is as shown in Figs. 8 to 11, clear ink Undermost clear ink layer 170 directly overlays through hole 180 and first through hole 181 in layer group 17.Clear ink layer group 17 In remaining clear ink layer 170 be sequentially coated on undermost clear ink layer 170.Because clear ink layer 170 is covered Conceal through hole 180, first through hole 181, and the second through hole 183.User is from the point of view of the front of terminal 1000, with reference to Fig. 1 and figure 2, through hole 180 and first through hole 181 are can't see, the effect of the structure of simplified terminal 1000 has been reached.

In some embodiments, when signal is optical signal, with reference to figures 10 to Figure 12, signal projector 31 can be position In the underface of through hole 180 so that the emitting head or exiting surface of signal projector 31 just to the through hole 180, are easy to signal to send out Emitter 31 launches optical signal, lifts the precision of proximity transducer 30.

In some embodiments, the incidence surface or photosurface of signal receiver 32) can just to first through hole 181, Lift the precision of proximity transducer 30.Figure 10 is such as referred to, the top surface 320 of signal receiver 32 is that photosurface can be just to first Through hole 181；It is again that photosurface can be logical just to first such as with reference to the top surface 320 of signal receiver 32 in Figure 11 encapsulating structures 33 Hole 181.

In some embodiments, with reference to Figure 10 and Figure 11, ambient light sensor 40 can be located at the second through hole 182 just Lower section, the top surface of ambient light sensor 40 is that photosurface can be just to the second through hole 182.

Wherein, the shape of through hole 180 and through hole such as first through hole 181, the second through hole 182 or through hole 183 can basis Actual demand is set.Such as, it can be formed for circle, rectangle, round rectangle etc..Through hole 180 and hole size can also bases Actual demand is set, such as, when can be circular port, and aperture can be between 1.1mm-1.3mm, or between 2mm-3mm.This Embodiment receives signal (such as optical signal) to improve signal receiver 32 (such as signal receiver 321 and ambient light sensor 40) Ability, lifted sensor sensitivity, opening for first through hole 181, the second through hole 182 or shared through hole 183 can be caused Hole area is more than the perforated area of through hole 180.

In the utility model embodiment, due to the only perforate in black-out ink layer 18 (i.e. the second adhesion layer), not saturating Upper perforate, can simplify cover plate layout designs and manufacture craft, relative to existing in gloss oil layer of ink 170 (i.e. the first adhesion layer) For technology, the appearance power of terminal 1000 with the manufacture craft of simplified intelligent terminal, can be greatly improved.

Further, since the only perforate in black-out ink layer 18, the not perforate on clear ink layer 170, thus without eventually End 1000 outward appearance perforate limitation, therefore in black-out ink layer 18 perforate size and shape it is unrestricted, can be according to biography The demand of the actual transmitting-receiving light of inductor component (being usually that hole is the bigger the better) opening up, improves the flexibility of perforate and close The performance of sensor 30 and ambient light sensor 40.

Thus, with reference to Figure 13 and Figure 14, so that signal is optical signal as an example, the process close to sensing is：Signal projector 31 Optical signal is produced, optical signal is transmitted to the external world through through hole 180 and clear ink layer 170, is reflected onto after encountering shelter 70 Cover plate 10, then reflexes to shelter 70 by cover plate 10, and so after shelter 70 and cover plate 10 reflect, optical signal is passed through Clear ink layer 170 and first through hole 181 are received by signal receiver 32.

The process of environment photoinduction：External environmental light passes through clear ink layer 170 and the second through hole 182, now, ambient light Sensor 40 will sense external environmental light.

With reference to Figure 15, when signal receiver 32 and ambient light sensor share receiver hole, so that signal is optical signal as an example, It is close to the process sensed：Signal projector 31 produces optical signal, and optical signal is transmitted through through hole 180 and clear ink layer 170 To extraneous, encounter and cover plate 10 is reflected onto after shelter 70, shelter 70 is then reflexed to by cover plate 10, so by shelter 70 and cover plate 10 reflect after, optical signal through clear ink layer 170 and through hole 183 received by signal receiver 32.

The process of environment photoinduction：External environmental light passes through clear ink layer 170 and through hole 183, now, ambient light sensing Device 40 will sense external environmental light.

If in view of the distance between signal projector 31 and signal receiver 32 it is closer when, due to clear ink layer 170 block, and signal (such as optical signal) transmitance is very low, signal (such as optical signal) will clear ink layer 170 in diffraction, and around Value is penetrated than larger, now, signal receiver 32 will direct full scale, i.e. the current proximity values of signal receiver 32 leap to The maximum or higher limit of proximity values scope, terminal 1000 (such as take for terminal 1000 close to blocking it is possible that maloperation Thing carries out putting out screen operation).The proximity values of the follow-up signal receiver 32 will not also change in addition, will not sense signal (such as optical signal) changes, it is impossible to which whether monitoring terminal 1000 reduces sensitivity, the sensing of proximity transducer 30 close to shelter Accuracy and performance.

In order to avoid proximity transducer 30 is because of the signal such as direct full scale of light diffraction, so as to improve proximity transducer 30 Sensitivity, sensing accuracy and performance, the present embodiment can zoom out the distance between signal projector 31 and signal receiver 32. Preferably, with reference to figures 10 to Figure 12, the distance between signal projector 31 and signal receiver 32 d can be at 2 millimeters to 3 millimeters Between, the distance between signal projector 31 and signal receiver 32 can be launched centered on away from (i.e. centre distance), i.e. signal The distance between the center of device 31 and the center of signal receiver 32.Such as, between signal projector 31 and signal receiver Distance or centre-to-centre spacing can be between 2.5 millimeters to 3 millimeters.

Correspondingly, the distance between through hole 180 and first through hole 181 can between 2 millimeters to 3 millimeters, through hole 180 with The distance between first through hole 181 can centered on away from, i.e., between the center of through hole 180 and the center of first through hole 181 away from From.

Correspondingly, when sharing through hole 183, the distance between through hole 180 and through hole 183 can 2 millimeters to 3 millimeters it Between, the distance between through hole 180 and through hole 183 can be centered on away from that is, between the center of through hole 180 and the center of through hole 183 Distance.

Because the distance between signal projector 31 and signal receiver 32 become big, therefore, pass through clear ink layer 170 Tail off if the signal (such as optical signal) for being mapped to signal receiver 32, signal receiver 32 will not oneself full scale, that is, jump to Maximum proximity values.

In some embodiments, in order to which the signal (such as optical signal) for preventing signal projector 31 from launching is directly entered signal Receiver 32 or by diffraction entering signal receiver 32 in cover plate 10, causes the direct full scale of signal receiver 32, can be with A protective case is set to entangle signal projector 31 and signal receiver 32 respectively, the signal that barrier signal projector 31 is launched is (such as Optical signal) it is directly entered signal receiver 32 or by diffraction entering signal receiver 32.Specifically, with reference to Figure 16 and figure 17, proximity transducer component 11 can also include protective case 70, and the protective case 70 is provided with first set hole 701 and second set of hole 702, First set hole 701 is socketed the signal projector 31, and second set of hole 702 is socketed the signal receiver 32.Wherein, protect Set 70 can be connected with cover plate 10, and specifically protective case 70 can be connected with the lower surface of cover plate 10, and such as top surface of protective case 70 is with hiding The lower surface 184 of gloss oil layer of ink 18 is contacted.The blocking effect of signal (such as optical signal) can so be increased.

Wherein, the shapes and sizes in first set hole 701 can be according to the shape of signal projector 31 and big on protective case 70 Small setting；The shapes and sizes in same second set of hole 702 can be set according to the shapes and sizes of signal receiver 32.Such as, The shape for covering hole can be rectangle, round rectangle etc..With reference to Figure 17, the shape that hole is covered on protective case 70 can be round rectangle. The protective case 70 can be Silicone Case, and its material can stop the material of optical signal from any.

With reference to Figure 18, when signal projector 31 and signal receiver 32 are arranged on encapsulating structure 33.The first of protective case 70 The socket of hole 701 signal projector 31 is covered, second set of hole 702 is socketed signal receiver 32.Wherein, wherein, protective case 70 can To be connected with cover plate 10, specifically protective case 70 can be connected with the lower surface of cover plate 10, such as top surface of protective case 70 and black out ink The lower surface 184 of layer 18 is contacted.The blocking effect of signal (such as optical signal) can so be increased.

Thus, because signal projector 31 and letter have been entangled in the first set hole 701 of protective case 70 and second set of hole 702 respectively Number receiver 32, the signal (such as optical signal) that therefore, it can the transmitting of block signal transmitter 31 is directly entered signal receiver 32 Or pass through the diffraction entering signal receiver 32 of cover plate 10 so that and the direct full scale of signal receiver 32, improve proximity transducer 30 sensitivity and accuracy.

To be better achieved close to sensing, sensitivity, sensing accuracy and the performance of proximity transducer 30 are further improved, On the basis of distance of the present embodiment between increase signal projector 31 and signal receiver 32, signal reception can also be increased The corresponding range of device 32, i.e., the proximity values scope achieved by signal receiver 32, further to avoid because of signal, (such as light is believed Number) diffraction causes the situation of direct full scale.

When signal receiver 32 is signal receiving chip, the corresponding range of signal receiving chip is by signal receiving chip What digit was determined, the signal receiving chip can be light-receiving chip.Such as, when signal receiver 32 is light-receiving chip, 8 (i.e. 8bit), 10 (i.e. 10bit), the corresponding range of light-receiving chip of 12 (i.e. 12bit) are 256 respectively, 1024, 4096.Therefore, the present embodiment can lift range from the higher light-receiving chip of digit, and then lift proximity transducer 30 Performance and close to sensing accuracy.The light that the present embodiment proximity transducer 30 is more than or equal to 16bit from digit connects Receive chip.Such as, 16bit light-receiving chip can be selected, now, the corresponding range of light-receiving chip is 65536.

Wherein, the distance between the digit of light-receiving chip and transceiver module have certain corresponding relation.Specifically, select The digit of light-receiving chip is bigger, and the corresponding range of light-receiving chip is bigger, then signal projector 31 and signal connect It is smaller that the distance between receipts device 32 can be set；If the digit anyway from light-receiving chip is smaller, light-receiving chip pair The range answered is just smaller, in order to prevent because internal diffraction causes direct full scale, then signal projector 31 and signal are received The distance between device 32 is accomplished by the bigger of setting.

Measured by many experiments, following chip digit can be obtained and apart from (signal projector 31 and signal are received Centre-to-centre spacing between device 32) relation table：

Digit (bit)	Distance (millimeter)
		16	6-14
32	5-15
		64	4-16

Wherein, represented in the table per a line, in the light-receiving chip from corresponding digit, signal projector 31 and signal Scope between receiver 32 where centre-to-centre spacing.

After increase the distance between signal projector 31 and signal receiver 32, the signal received (such as believe by light Number) attenuation ratio it is more serious, can so cause the proximity values that signal receiver 32 is obtained when unobstructed and certain distance is blocked Very close, proximity values variable quantity less, and then causes the sensing accuracy and Performance comparision of proximity transducer 30 low.In order to overcome Foregoing problems, the present embodiment can increase the power of transmitting terminal, such as increase the operating current of signal projector 31, to increase transmitting Power, so that signal receiver 32 can obtain sufficiently large close values variable quantity when unobstructed and certain distance is blocked.

In practical application, the operating current of signal projector 31 can be between 90 milliamperes to 110 milliamperes.It is preferred that can Think 100 milliamperes.

For the purposes of lifting sensitivity, sensing accuracy and the performance of proximity transducer 30, the present embodiment, which can increase, to be connect Receiving end is gain and the time of integration of signal receiver 32.Such as, can be with the signal gain amplifier of setting signal receiver 32 For 64 times, the time of integration is 370us etc..

Alternatively, it is contemplated that had influence on very much close to sensing if the distance between proximity transducer 30 and cover plate 10 are improper The sensitivity of device 30 or accuracy, such as, cause signal (such as optical signal) attenuation ratio more severe, signal receiver 32 apart from excessive Signal (such as optical signal) intensity sensed is relatively actual weaker, and such as, apart from too small, increases signal (such as optical signal) in cover plate The degree of internal diffraction in 10, therefore, if the distance between proximity transducer 30 and cover plate 10 can be reduced close to sensor 30 Sensitivity or accuracy.In order to overcome the distance between proximity transducer 30 and the cover plate 10 in the problem, the present embodiment It such as can be 0.3 millimeter, 0.32 millimeter between 0.25 millimeter to 0.35 millimeter.

Wherein, the distance between proximity transducer 30 and the cover plate 10 can be the top surface of proximity transducer 30 and black out ink The distance between 18 (i.e. the second adhesion layer) bottom surface of layer.

When signal receiver 32 and signal projector 31 are encapsulated in encapsulating structure 33, the proximity transducer 30 with it is described The distance between cover plate 10 can be the distance between encapsulating structure 33 and cover plate 10, specifically, be the top surface of encapsulating structure 33 with The distance between black-out ink layer 18 (i.e. the second adhesion layer) bottom surface.As shown in figure 9, the top surface 330 of the encapsulating structure 33 is with hiding The distance between bottom surface 184 of gloss oil layer of ink 18 is AG (Air Gap, the air gap) between 0.25 millimeter to 0.35 millimeter.

In the case where signal receiver 32 and signal projector 31 are highly consistent, the proximity transducer 30 and the cover plate The distance between 10 can be signal receiver 32 or the top surface of signal projector 31 and (the i.e. second attachment of black-out ink layer 18 The distance between layer) bottom surface.As shown in figure 9, the top surface 320 of signal receiver 32 and black-out ink layer 18 (i.e. the second adhesion layer) The distance between bottom surface 184 is AG (AirGap, the air gap) between 0.25 millimeter to 0.35 millimeter.

In some embodiments, in the case where signal receiver 32 and signal projector 31 are highly inconsistent, this connects The distance between nearly sensor 30 and the cover plate 10 can be with the tops of higher device in signal receiver 32 and signal projector 31 The distance between face and black-out ink layer 18 (i.e. the second adhesion layer) bottom surface 184.As signal projector 31 is higher than signal receiver When 32, the distance between the proximity transducer 30 and the cover plate 10 can be the top surface of signal projector 31 and black-out ink layer 18 The distance between (i.e. the second adhesion layer) bottom surface 184.

It should be understood that：In the utility model embodiment accompanying drawing between signal receiver 32 and signal projector away from From, be not the actual range between signal receiver 32 and signal projector 31, what accompanying drawing was functioned only as be signal effect, together Reason is also for the distance between proximity transducer 30 and described cover plate 10.

Alternatively, in actual applications, signal receiver 32 can be from the higher signal receiver 32 of the linearity.

Wherein, the linearity is referred to：Refer to and receive variable quantity with caused by the change close to distance.Existing general device is all It is that the linearity is poor.Poor is meant that：Apart from it is close when variable quantity also can very acutely, distance a little further when Variable quantity is smaller.

And if the linearity is good, be exactly regardless of distance, variable quantity is all similar, variable is maintained at into one puts down Steady value, improves the accuracy and applicability of proximity transducer.Even if in addition, the low situation of white ink layer transmitance Under, it proximity transducer is sensed variable quantity, as long as the amount of changing, breath screen distance can also meet requirement, therefore, improve Close to the scope of application of the sensitivity of inductor, and proximity transducer.
