Embodiment
Clearer for technical matters, technical scheme and beneficial effect that the utility model is solved, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein only in order to explanation the utility model, and be not used in qualification the utility model.
Please refer to shown in Figure 1, a kind of electrochromism catoptron, comprise first transparency carrier 1 and second transparency carrier 2 that are oppositely arranged, the inside surface of described first transparency carrier is provided with first transparency conducting layer 11, the inside surface of second transparency carrier is provided with second transparency conducting layer 21, the circumferential edges of described first transparency conducting layer and second transparency conducting layer is provided with envelope frame glue 3, described envelope frame glue, first transparency conducting layer and second transparency conducting layer surround a cavity, accommodate electrochromic material 4 in the described cavity, the outside surface of described second transparency carrier has reflection horizon 5, further, between described second transparency carrier and reflection horizon, has semitransparent layer 6.The inside surface of aforementioned first transparency carrier and second transparency carrier is both facing surfaces; Accordingly, described outside surface is another surface with the opposing transparency carrier of inside surface.
The material of described first transparency conducting layer 11 and second transparency conducting layer 21 can be any material of secure bond to first substrate, can resist the corruption of any material in the electrochromic device, the corruption of Chinese People's Anti-Japanese Military and Political College's gas, and minimum diffuse reflection or direct reflection arranged, high light transmission, approximate neutral color and good electrical conductivity.Particularly, described transparent conductive material can be a kind of in fluorine doped tin oxide, doping zinc-oxide, indium-zinc oxide and the indium tin oxide (ITO), perhaps other transparent conductive material.Those skilled in the art should know, and the electric conductivity of transparent conductive material depends on its thickness and composition, compares with other conductive materials, and the ITO conductive material has higher conductivity usually.Further, the thickness of described first transparency conducting layer and second transparency conducting layer is 5-20nm.
Brown semitransparent layer 6 can by the deposition mode be formed on the outside surface of second transparency carrier, semitransparent layer comprises one deck trnaslucent materials at least, this material can be selected from silver, aluminium, the chromium any one or several, perhaps include in silver, aluminium, the chromium any one alloy.Preferably, described trnaslucent materials adopts aluminium or comprises the alloy of aluminium.
Described semitransparent layer need have certain transmitance, and described transmitance is more than or equal to 15%, if transmitance less than 15%, the user can not see the information that electronic display module shows, preferred transmitance is more than or equal to 20%.The thickness of described semitransparent layer is 50-500nm, is arranged to the semitransparent layer of described thickness, can guarantee to obtain the transmitance more than 15% of aforementioned requirement, and preferred thickness is 100-300nm.
The material requirements that use in described reflection horizon does not have can corrode semitransparent layer, protects metal level not to be subjected to scratch and other physical disturbance simultaneously; Simultaneously, itself should possess enough environment intensity, be applicable to environment temperature or pressure condition occasion that catoptron uses.Thus, described reflection horizon can be resin type coating or glued membrane paste layer, and described resin type coating can adopt epoxy coating.When the glued membrane paste layer was adopted in described reflection horizon, described glued membrane paste layer can adopt the glued membrane paste layer of blueness or other color such as white or grey.The reflectivity in described reflection horizon is more than or equal to 70%, and preferably, the reflectivity in described reflection horizon is more than or equal to 80%.
Further, the problem of turn to be yellow easily in order to solve existing part electrochromism rear-vision mirror face (yellow is human disagreeable colors, and such mirror can produce visual pollution), preferably, the color of described glued membrane paste layer be a blueness.Simultaneously,, can prevent in traditional electrochromism mirror structure that the reflection horizon takes place owing to adhere to the bad caducous phenomenon in reflection horizon that causes on smooth glass substrate because the surface ratio glass surface of semitransparent layer is coarse.
In order to protect the electrochromic material life-span can be because of ultraviolet ray or ultrared irradiation and shortening; have light filtering layer 7 between described first transparency carrier and first transparency conducting layer, described light filtering layer 7 can be ultraviolet ray or ultrared absorption layer or reflection horizon.The material of described light filtering layer can be selected for use possesses ultraviolet ray or infrared ray absorbing or reflection potential, is suitable as any one material that coating material uses simultaneously again.
The material of described envelope frame glue can be selected the link epoxy resins of this area routine for use; Described electrochromic material can be selected for use liquid or gelatinous electrochromic material, as for the formation of electrochromic material itself with select for use, has been conventionally known to one of skill in the art, does not repeat them here.
