32 are vertically arranged, so that the transmitting optical axis 31 of infrared transmitter 33 is obliquely installed relative to horizontal direction, so that red
After the transmitting optical axis 31 of external transmitter 33 passes through light hole 142, it can be tilted to the front side of substrate 12, so that infrared transmitter 33
The infrared light of sending can be incident upon the front side of touch display screen 20.
Although be appreciated that the transmitting optical axis 31 of infrared transmitter 33 perpendicular to circuit board 32, due to infrared emission
The infrared light that device 33 issues has certain angle of departure, and therefore, the infrared light that infrared transmitter 33 issues can be relative to circuit
Plate 32 tilts.
Fig. 5 and Fig. 9 is please referred to, in one example, inclined angle c is 30-60 to circuit board 32 relative to horizontal direction
Degree.For example, angle c be 30 degree, 35 degree, 45 degree, 50 degree or 60 degree angularly.
Also referring to Figure 10-Figure 12, in some embodiments, infrared transmitter 33 is including photo-emission source 331 and thoroughly
Optical element 332.Photo-emission source 331 is arranged in circuit board 32.Translucent element 332 is provide with photo-emission source 331.Translucent element 332 wraps
It includes preceding transmittance section 3321 and connects the rear transmittance section 3322 of preceding transmittance section 3321.Preceding transmittance section 3321 is located at photo-emission source 331
Emit the front side of optical axis 31.Transmittance section 3322 is located at the rear side of the transmitting optical axis 31 of photo-emission source 331 afterwards.Infrared remote receiver 34
In the side of photo-emission source 331.Proximity sensor 30 further includes shading element 35, light transmission after shading element 35 covers at least partly
Portion 3322.
In this way, shading element 35 blocks at least partly rear transmittance section 3322, so that being emitted from preceding transmittance section 3321 infrared
Light can be concentrated more, and the energy for the infrared light being emitted from preceding transmittance section 3321 is improved, so that the distance of infrared light outgoing is more
Far, it is also beneficial to infrared light and encounters 200 back reflection of object to return to infrared remote receiver 34, improve the detection energy of proximity sensor 30
Power.
Specifically, translucent element 332 can be made of translucent material.For example, the material of translucent element 332 is resin or glass
Glass.Translucent element 332 is provide with photo-emission source 331, and in other words, photo-emission source 331 is arranged in translucent element 332.Make in this way
The problems such as translucent element 332 can protect photo-emission source 331, and photo-emission source 331 is avoided to contact and damage with oxygen.
It should be pointed out that signified in the front side of " front side " and aforesaid substrate 12 signified in the front side of transmitting optical axis 31
The direction of " front side " is consistent.Therefore, the infrared light that photo-emission source 331 issues successively can after preceding light out part and light hole 142
To reach the front side of touch display screen 20, to detect whether touch display screen 20 is blocked.
It should be noted that shading element 35 extends to right side from the left side of rear transmittance section 3322.I other words rear transmittance section
3322 left back position and right rear are covered.Shading element 35 is, for example, the tool such as foam, black ink layer or metal layer
Have and blocks the element that infrared light passes through.
