As shown in Fig. 2, the terminal device includes light-guiding pillar 210, which is mainly to aid in the extraneous light of terminal device perception By force.The lower section of glass cover-plate 162 is arranged in light-guiding pillar 210, while display panel 161 is also disposed at the lower section of glass cover-plate 162, Display panel 161 is light-guiding pillar 210 along the position of X-axis positive direction.Environment light biography can also be successively arranged in the lower section of light-guiding pillar 210 Sensor 240, printed circuit board 280.The lower section of display panel 161 and right are arranged shells 260, and the shells 260 is by light-guiding pillar mould The lower section and right of group wrap up, to guarantee limit installation of the light-guiding pillar mould group in shells 260.Extraneous light enters glass After cover board, it can enter in light-guiding pillar, from the light of plane of incidence incidence light-guiding pillar, a part is led after side wall surface reflects Absorption of Medium around light beam;From another part light of plane of incidence incidence light-guiding pillar, reflection or total reflection occurs in side wall surface, To reach ambient light sensor 240, ambient light sensor 240, which can be perceived, to be occurred reflection in side wall surface or is totally reflected this part Light, to realize the light intensity in the 240 perception terminal equipment external world of ambient light sensor.
For example, Fig. 3 is the schematic three dimensional views of light-guiding pillar and ambient light sensor.As shown in figure 3, light-guiding pillar 210 include into Smooth surface 201 and light-emitting surface 202, the light-guiding pillar can be by by polycarbonate or polymethyl methacrylate materials thermoplastic shaping Preparation.Optionally, in order to guarantee limit installation of the light-guiding pillar on shells component, transparent light-guiding pillar often with opaque support Locating part or 230 double-shot moulding of shells gadget are integral.Simultaneously in order to avoid display backlight is to the shadow of ambient light sensing 240 It rings, usually wraps up black gum cover or the antistatic mylar of shading (Mylar) 220 in the side wall surface of light-guiding pillar, which resists quiet The optical index of voltolisation membrane of lipoprotein 220 is higher than the optical index of transparent light guide column.
The embodiment of the present application for ease of understanding first briefly describes several concepts involved in hereafter.
1, be totally reflected: also known as total internal reflection refers to light by optically denser medium (i.e. the big medium of refractive index of the light in this medium) When being mapped to the interface of optically thinner medium (i.e. light small medium of refractive index in this medium), it is all reflected back toward showing in former medium As.
2, critical angle: light is incident on optically thinner medium from optically denser medium, during incidence angle constantly increases, refraction angle also with Constantly increase, the incidence angle when refraction angle just increases to 90 degree is called critical angle.
3, the law of refraction of light: at refracted light and incident ray, normal in the same plane, refracted light and incident light Line is located at the two sides of normal;The sine of incidence angle and the sine at refraction angle are directly proportional, i.e.,
N in formula12It is the constant of ratio, referred to as relative index of refraction of the second medium to first medium;n1For first medium Refractive index;n2For the refractive index of second medium;θ1For the incidence angle of light;θ2For the refraction angle of light.
As shown in figure 4, when light from 201 oblique incidence of incidence surface and reach light-guiding pillar side wall surface and shading it is antistatic poly- When the interface of membrane of lipoprotein 220, light will not be totally reflected, but refraction and reflection occurs, and most of refraction light can quilt The antistatic mylar 220 of shading absorbs, so that the light for reaching ambient light sensor 240 is seldom, i.e. ambient light sensing The intensity for the ambient light that device 240 receives is reduced, and causes the terminal device for being provided with light-guiding pillar 210 and ambient light sensor 240 The field angle for experiencing ambient light is smaller, influences screen intensity automatic adjustment, causes user experience poor.
For example, as shown in figure 5, being a kind of possible path profile that light enters light-guiding pillar.Light enters light-guiding pillar 210 The incidence angle of incidence surface 201 is α1, refraction angle α2, the incidence angle that refracted light enters the antistatic mylar 220 of shading is α3, refraction angle α4.The refractive index n of air1It is 1;The refractive index n of the material of light-guiding pillar 2102It is 1.585;Shading is antistatic poly- The refractive index n of membrane of lipoprotein 2203It is 1.65.Assuming that when light reaches the side wall surface of light-guiding pillar 210, it may occur that total reflection, i.e. α4≥ It 90 °, according to the refractive index law of light, can obtain:
That is sin α3>=1.04, but sin α3It is up to 1, it is therefore, antistatic in the side wall surface package shading of light-guiding pillar 210 Mylar 220, when the light into light-guiding pillar 210 can be made to reach the side wall surface of light-guiding pillar 210, light will not be all-trans It penetrates.
Currently, taking some measures to improve the light intensity for reaching ambient light sensor 240, for example, entering in light-guiding pillar 210 Smooth surface 201 pastes equal mating plate, still, pastes equal mating plate on light-guiding pillar incidence surface 201, tolerance be it is uncontrollable, can production it is poor. In another example close to the side coated with multiple layer light of incidence surface 201 on the glass cover-plate above the incidence surface 201 of light-guiding pillar 210 Ink layer 280, as shown in Figure 2.But above-mentioned measure cannot achieve the light from light-guiding pillar 210 plane of incidence incidence in side wall surface It is totally reflected, and absorption of the antistatic mylar 220 of shading to light can not be reduced.Meanwhile the cost of coating oil layer of ink It is higher, cause deficiency in economic performance.
Based on this, light-guiding pillar mould group provided by the embodiments of the present application, by light-guiding pillar and the antistatic mylar of shading Between transparent material layer is set, the light that the incidence surface of incident light-guiding pillar may be implemented in target angle reaches the side of light-guiding pillar When wall surface, light is totally reflected, to increase the light for reaching ambient light sensor, increases the visual field of ambient light sensor Angle, while the production cost of light-guiding pillar can also be reduced.
The embodiment of the present application in order to facilitate understanding first makes following explanation before introducing the embodiment of the present application.
First, in the embodiment of the present application in all attached drawings, the direction of X-axis, Y-axis and Z axis is vertical two-by-two, the direction of Z axis It can be understood as the direction of the incidence surface and light-emitting surface perpendicular to light-guiding pillar;The direction of X-axis can be understood as the length of light-guiding pillar Direction;The direction of Y-axis can be understood as the direction in the two side walls face perpendicular to light-guiding pillar.
Second, in the embodiment of the present application, " top " or " lower section " refers to the positional relationship of Z-direction, and " on Side " refers to that, along Z axis positive direction, " lower section " is referred to along Z axis negative direction.
In the following, the light-guiding pillar mould group of the embodiment of the present application is described in detail in conjunction with Fig. 6 to Fig. 8.
It should be understood that the schematic diagram of Fig. 6 to light-guiding pillar mould group shown in Fig. 8 all schematically illustrates, any deformation Implementation or connection type all in the protection scope of the embodiment of the present application.
Fig. 6 is light-guiding pillar mould group schematic diagram provided by the embodiments of the present application.As shown in fig. 6, the leaded light mould group includes:
Light-guiding pillar 210, including opposite incidence surface 201 and light-emitting surface 202, opposite side wall surface;
The side wall surface of light-guiding pillar 210 is arranged in light shield layer 220;
Transparent material layer 250 is arranged between light-guiding pillar 210 and light shield layer 220, which makes from light-guiding pillar The refracted light that the side wall surface of light-guiding pillar 210 was injected and reached to 210 incidence surface 201 is totally reflected.
Optionally, the refractive index of the transparent material 250 is lower than the refractive index of the material of light-guiding pillar 210, and the transparent material 250 refractive index is higher than first threshold.
Optionally, above-mentioned first threshold is the material of the incidence angle and light-guiding pillar according to the incidence surface of light incidence light-guiding pillar Determining.
For example, as shown in fig. 7, being a kind of possible path profile that light enters light-guiding pillar mould group.Light enters light-guiding pillar The incidence angle of 210 incidence surface 201 is φ1, refraction angle φ2, the incidence angle that refracted light enters transparent material layer 250 is φ3, refraction angle φ4.The refractive index n of air1It is 1;The refractive index n of the material of light-guiding pillar 2102It is 1.585.Assuming that light reaches To light-guiding pillar 210 side wall surface when, it may occur that total reflection, i.e. φ4It >=90 °, according to the refractive index law of light, can obtain:
And due to:
According to the refractive index law of light, can obtain:
Again due to 0≤φ1≤ 90 °, then it can obtain n1>=1.2297, therefore, above-mentioned first threshold can take 1.23.
