Description
Technical field
The present invention relates to car light manufacturing technology field, particularly relate to a kind of full-sized car liquid crystal glareproof mirror.
Background technology
The auto industry in modern age, each parts is all along with the progressive continuous renewal of science and technology, successfully research and development and industrialization
It is applied to glareproof mirror in saloon car.But heavy type transport vehicle, Medium Truck, minibus, touring car and bus etc. still make
With traditional rearview mirror, when night, there was strong illumination at rear, through the reflection of rearview mirror, the eyes dizziness of driver, cause raw friendship
Interpreter's event.
Electricity look rearview mirror is plating last layer electric material on transparent electrically-conductive backing plate, and the albedo of light is passed through by mirror
Electrochemical process is controlled by, and makes the electrochrome optical property in electricity look mirror change by applying voltage, thus weakens rearview mirror
Albedo to light.
GENTEX company of the U.S. is that the world mainly produces glareproof mirror manufacturer.Electricity look mirror is slow by bright dimmed conversion speed,
Large scale rearview mirror can not be manufactured for oversize vehicle.
United States Patent (USP) U.S.Patent 3,597, the 044 a kind of technology disclosed, be liquid crystal and dyestuff are clipped in
Between reflecting plate and ito glass, use the nematic crystal of positive dielectric anisotrop, under electric field action, present on state of.1988
Year Deutsche Bundespatent GB2,205,075 are disclosed that aluminium film is placed in the outer surface of bottom glass as reflecting surface, by liquid crystal and list
Automobile rearview mirror made by look dyestuff.Above-described liquid crystal rearview mirror uses positive dielectric anisotropic liquid crystals to mix with dichroic dye
Compound pours in liquid crystal cell.Being dark-state when no power, become on state of after energising, even if by day, rearview mirror also must be opened
Electric-control system.
The quick liquid crystal rearview mirror with an automatic light meter (Chinese invention patent CN 1278887C) that discloses of state in 2004, uses negative
The property nematic crystal of dielectric anisotropy, vertical orientated material, dichroic dye and relevant chemical material, make liquid crystal
Show device, tie line and shell, form liquid crystal rearview mirror with an automatic light meter.This rearview mirror and with positive dielectric anisotrop to
Row type liquid crystal is contrary, when daytime uses, is not required to connect power supply, and minute surface presents on state of, and its back vision function is as conventional mirror.Night
The chien shih used time, when there is strong illumination at rear, photosensor triggers Circuits System, makes circuit open, and minute surface is the most dimmed, now rearview mirror
Lower the albedo to light, make light not stimulate eyes, it is ensured that night safe travels.
In sum, electricity look and liquid crystal glareproof mirror, oneself is applied to little saloon car, is arranged in car.The biggest
Type transport vehicle, Medium Truck, minibus, touring car and bus car external application glareproof mirror.Main cause is: anti-dazzle back vision
Mirror is arranged on the outer both sides of car, and display area is big, and electricity look mirror is slow by bright dimmed conversion speed, can not manufacture large scale rearview mirror and supply
Oversize vehicle uses.Liquid crystal glareproof mirror is made up of the material such as liquid crystal and dichroic dye, and these materials are to UV stable
Property poor, when strong illumination, ultraviolet damage liquid crystal and dye molecule, the display screen life-span is short, in the winter time temperature be less than-20C liquid
The series of problems such as brilliant material cisco unity malfunction.
