Below in conjunction with the accompanying drawing among the utility model embodiment, the technical scheme among the utility model embodiment is clearly and completely described, obviously, described embodiment only is the utility model part embodiment, rather than whole embodiment.Based on the embodiment in the utility model, those of ordinary skills are not making the every other embodiment that obtains under the creative work prerequisite, all belong to the scope of the utility model protection.
The utility model embodiment provides a kind of anti-dazzle rear view mirror, anti-dazzle better function, and speed of response is fast.
Below by specific embodiment the technical solution of the utility model is described in detail, sees also Fig. 1 to Fig. 4:
A kind of anti-dazzle rear view mirror, comprise: Liquid Crystal Display (LCD) 1, the drive circuit board 3 that is used for gathering the photosensor 2 of light and is used to Liquid Crystal Display (LCD) 1 power supply, drive circuit board 3 is regulated the driving voltage size of supplying with Liquid Crystal Display (LCD) 1 according to the induction of 2 pairs of light of photosensor, with the reflectivity of control Liquid Crystal Display (LCD) 1; Wherein, Liquid Crystal Display (LCD) 1 comprises: by the liquid crystal cell 11 that top glass substrate 111, lower glass substrate 112 and edge sealing adhesive 113 surround, liquid crystal cell is filled negative liquid crystal 12 and coloured dyestuff 13 for 11 li.
Optionally, negative liquid crystal 12 can be the guest-host type liquid crystal, and this negative liquid crystal 12 and coloured dyestuff 13 can form host and guest's relation.
Optionally, can be at lower glass substrate 112 plating one deck reflectance coatings 4, this reflectance coating 4 can improve the reflectivity of Liquid Crystal Display (LCD).Wherein, this reflectance coating 4 can be metallic reflective coating, this reflectance coating can be plated in inboard or the outside of lower glass substrate 112, also can all be coated with one deck reflectance coating 4 in inboard and the outside.
See also Fig. 1, the anti-dazzle rear view mirror in the present embodiment comprises: Liquid Crystal Display (LCD) 1, the drive circuit board 3 that is used for gathering the photosensor 2 of light and is used to Liquid Crystal Display (LCD) 1 power supply.Wherein, photosensor 2 can be according to the power of induction light, when running into high light, the high light that drive circuit board collects according to photosensor 2, the driving voltage of supplying with Liquid Crystal Display (LCD) 1 is reduced, make the reflectivity of Liquid Crystal Display (LCD) 1 reduce, can well reach anti-dazzle purpose.
Further, can also reach anti-dazzle purpose by negative liquid crystal 12 and coloured dyestuff 13 of filling on the Liquid Crystal Display (LCD) 1, in conjunction with above-mentioned, specifically can be as follows:
See also Fig. 2, Liquid Crystal Display (LCD) 1 comprises: by the liquid crystal cell 11 that top glass substrate 111, lower glass substrate 112 and edge sealing adhesive 113 surround, liquid crystal cell is filled negative liquid crystal 12 and coloured dyestuff 13 for 11 li, is coated with one deck reflectance coating 4 in the inboard of lower glass substrate 112.
