Further, in above-mentioned light transmission device 100, the difference of the refractive index of the first transparency carrier 101 and the refractive index of transparent pattern 102 can be less than or equal to 0.1.Now, because the first transparency carrier 101 is close with the refractive index of transparent pattern 102, thus the incident ray through transparent pattern 102 and the first transparency carrier 101 can not be made to reflect, thus when user observes object by light transmission device 100, the observation to object and judgement can not be affected.
In above-mentioned light transmission device 100, the transparency of the first transparency carrier 101, the transparency of transparent pattern 102 can be greater than or equal to 10% and be less than or equal to 97%.So, the transparency due to transparent pattern 102 or the first transparency carrier 101 can be avoided too low and obstruct the light, thus affecting user when user observes object by light transmission device 100 to the observation of object and judgement.
Further, light transmission device 100 can also comprise the one side that the second transparency carrier 103, second transparency carrier 103 has transparent pattern 102 by solid 104 and the first transparency carrier 101 and bonds together.After bonding second substrate; transparent pattern 102 can be securely fixed between the first transparency carrier 101 and the second transparency carrier 103; second transparency carrier 103 and the first transparency carrier 101 can also play the effect of protection transparent pattern 102 simultaneously; avoid external environment to the wearing and tearing of transparent pattern 102, thus effectively can ensure the serviceable life of light transmission device 100.Exemplary, the new light transmission device by obtaining after bonding second transparency carrier of solid 104 on the basis of the light transmission device shown in Fig. 1 can see Fig. 5.
Wherein, the kind of the second transparency carrier 103 can comprise glass substrate, high temperature resistance polyester film, Kapton or polyvinyl alcohol film.Certainly, the second transparency carrier 103 also can be transparency carrier or the transparent membrane of other kind, does not limit here.
After bonding second transparency carrier 103, in the refractive index of the refractive index of the refractive index of the refractive index of the second transparency carrier 103, the first transparency carrier 101, solid 104, transparent pattern 102, difference between any two can be less than or equal to 0.1.So, because the second transparency carrier 103, solid 104, transparent pattern 102, first transparency carrier 101 are close with the refractive index of transparent pattern 102, thus can not make to reflect through the incident ray of the second transparency carrier 103, solid 104, transparent pattern 102 and the first transparency carrier 101 successively, thus when user observes object by light transmission device 100, the observation to object and judgement can not be affected.
Further, after bonding second transparency carrier 103, the transparency of the second transparency carrier 103 and the transparency of solid 104 also can be greater than or equal to 10% and be less than or equal to 97%.Equally, the transparency due to the second transparency carrier 103 or solid 104 can be avoided too low and obstruct the light, thus affecting user when user observes object by light transmission device 100 to the observation of object and judgement.
The embodiment of the present invention provides a kind of light transmission device 100, by arranging transparent pattern 102 on the surface of the first transparency carrier 101, and be coated with light-proof material 1021 in the localized area on transparent pattern 102 surface, thus make to incide the light that transparent pattern 102 surface is coated with the region of light-proof material 1021 and thus can not be transmitted owing to being blocked by light-proof material 1021, and incide transparent pattern 102 surface and uncoatedly have the light in the region of light-proof material 1021 to be transmitted, namely to be coated with the transmittance in the direction of the light in the region of light-proof material 1021 low to inciding transparent pattern 102 surface for light transmission device 100, and to inciding, transparent pattern 102 surface is uncoated has the transmittance in the direction of the light in the region of light-proof material 1021 high, thus the problem that light transmission device 100 of the prior art can not control the transmittance of the light of different incident direction can be solved.Further, effect that is fixing and protection transparent pattern 102 can also be played by bonding second transparency carrier 103, thus effectively can ensure the serviceable life of light transmission device 100.
The embodiment of the present invention provides a kind of manufacture method of light transmission device, see Fig. 6, the method mainly can comprise step 601 and step 602, specific as follows:
601, the first transparency carrier that surface has transparent pattern is made.
