Description
Technical field
The utility model relates to electrochromism technical field, particularly relates to electronic anti-dazzle ocular lens and display screen technology.
Background technology
The situation of automobile rearview mirror reflection automobile rear, side and below, make driver indirectly can see the situation of these positions clearly, it plays a part " second eye ", expands the field range of driver.Rearview mirror divides with installation site, divides and has outside rear-view mirror, lower rearview mirror and inside rear-view mirror.Divide with purposes, outside rear-view mirror reflection automotive back side, lower rearview mirror reflection automobile front lower place, inside rear-view mirror reflects situation in automobile rear and car.Inside rear-view mirror is arranged on below compartment front windshield.Inside rear-view mirror is mainly divided three classes: common inside rear-view mirror, common anti-glare inner rear-view mirror, Electronic Dimming Inside Rearview Mirror.The rear view mirror lens of common inside rear-view mirror is a level crossing, and the reflectivity of minute surface cannot free adjustment.Common anti-glare inner rear-view mirror, also known as manual anti-dazzle driving mirror, its rear view mirror lens is a prism, the reflectivity of different minute surface is different, the intensity of reflection ray is also just different, there is a manual adjustments toggle bottom this rearview mirror, changed the reflectivity of rearview mirror by driver according to external environment oneself accommodation reflex face.At present, inside high-end automobile, inside rear-view mirror generally adopts automatic anti-glare eyeglass, and this eyeglass is a kind of special galvanochemistry eyeglass.As shown in Figure 1, this eyeglass comprises dizziness-prevention lenses reflection horizon glass 4, electrochromic material layer 5, dizziness-prevention lenses projection layer glass 6, and eyeglass lower edges is fixed with eyeglass negative pole 7 and eyeglass positive pole 8.When applying certain DC voltage to electrode, will there is electrochemical reaction in middle electrolyte layer, thus reduce the reflected light of back reflection glassy layer, and reflectivity is reduced to less than 10% by from 60% of normal condition, reaches abblendbar effect.
In addition, in order to increase the additional function of inside rear-view mirror, inside rearview mirror, be often furnished with display module, or as charactron, LCD display OLED display screen etc., in order to show character, numeral, image or video.So just require that dizziness-prevention lenses above must be semi-transparent semi reflective state, common practices is windowed according to viewing area by the black blow-out disc launched after glassy layer, like this, part of windowing is semi-reflection and semi projection state, and other parts are total reflection states.So just need the function increasing display screen in anti-dazzle driving mirror.Current solution as shown in Figure 1, display screen is a liquid crystal display, this liquid crystal display comprises rear layer glass 1, material packed layer 2, front layer glass 3, and after this display screen is placed on inside rear-view mirror eyeglass, and there is certain distance between display screen and inside rear-view mirror eyeglass.About automatic anti-glare eyeglass and display screen technology can application reference number be 201410248370.7 the semi-permeable mirror for minute surface display screen; application number is touch-screen and the rearview mirror display screen of 201220579345.3; application number is a kind of Transflective electronic anti-dazzle order rear view mirror lens of 201310039035.1, and application number is a kind of liquid crystal with diaphragm anti-glare inner rear-view mirror with an automatic light meter of 201320618496.X.
But, there are some unavoidable defects in technique scheme: first, layer glass and one deck electrolytic solution is had before display screen, even if be designed to half projection half reflection state, also greatly transmitted light can be reduced, like this in order to reach set display brightness, display backlight brightness must be transferred to very high, otherwise is difficult to when extraneous light is stronger the displaying contents seeing display screen clearly.The second, display screen and dizziness-prevention lenses have layer glass structure, so virtually add the cost of product, weight and thickness.3rd, have certain space in the middle of dizziness-prevention lenses and display screen, in order to prevent the ghost phenomena because lens reflecting produces, display screen surface also needs to increase the pad pasting that one deck reduces reflection, so not only turn increases cost, but also reduces brightness.
