Specific embodiment
In order to make those skilled in the art better understand the scheme of the utility model, with reference to the accompanying drawing and specific implementation
The utility model is described in further detail for mode.Obviously, described embodiment is only the utility model a part
Embodiment, instead of all the embodiments.Based on the embodiments of the present invention, those of ordinary skill in the art are not doing
Every other embodiment obtained under the premise of creative work out, fall within the protection scope of the utility model.
As shown in Figure 1, for the schematic diagram of the section structure of electrochromic device provided by the utility model embodiment, the electricity
Mutagens color device includes:
The first transparent substrate 1, the first conductive layer 2, electrochromic layer 3, the second conductive layer 4 and second set gradually is saturating
Bright substrate 5.
Specifically, electroluminescent for automobile anti-dazzle back vision mirror, display, light-sensitive sunglasses, discoloration door and window and Electronic Paper etc.
Electrochromic device, the first transparent substrate 1 and the second transparent substrate 5 may each be glass substrate, but in the utility model also not
Exclude the substrate using transparent resin material.
The electrochromic layer 3 specifically, can be the EC liquid being packaged between the first conductive layer 2 and the second conductive layer 4, should
First conductive layer 2 and the second conductive layer 4 specifically can be ITO conductive layer.Certainly, the electrochromic layer 3 in the utility model
It is also possible to other similar electrochromic material to be formed by；Similarly, the first conductive layer 2 and the second conductive layer 4 also not only limit
In ITO conductive layer, this is not being enumerated.
Wherein, it is additionally provided with dielectric layer 6 between the first transparent substrate 1 and electrochromic layer 3, which is that can make
The changed film layer of the curve of spectrum of visible light.It is to be understood that when light is by a kind of medium incident to another medium,
Its reflectivity and transmissivity be it is corresponding, the light of a certain wavelength, transmissivity is higher, then reflectivity is also lower,
Conversely, its reflectivity is higher, transmissivity is also lower.The main function of the utility model dielectric layer 6 is exactly to improve to need electricity
The transmissivity for the light color that mutagens color device is presented, and reduce the transmissivity of other light.
It should be noted that can be luminous ray for electrochromic device transmitted through electrochromic device and enter people
Eye and the color, such as electrochromism door and window, light-sensitive sunglasses etc. observed, it is seen that the light of light is from the incidence of the first glass substrate
Across electrochromic layer, second glass substrate etc., finally it is incident in human eye realization；It is also possible to this device of Antiglaring rear mirror
Part, also needs to be arranged between the second conductive layer 4 and the second transparent substrate 5 reflecting layer, and eye-observation to light be from
One transparent substrate 1 is incident to pass through the transmission such as dielectric layer 6, electrochromic layer 3, reaches reflecting layer back reflection, again passes through electroluminescent change
Human eye is incident to after the transmission such as chromatograph 3, dielectric layer 6, first transparent substrate 1.Therefore the light that user finally observes may be

The color of color, the electrochromic device in the utility model is more rich and varied, meets user to the individual character of electrochromic layer
The demand of change.
Based on the above embodiment, in the utility model another specific embodiment, dielectric layer 6 can be antireflective coating.
For example, the thickness of the anti-reflection film is equal to red light in a quarter of anti-reflection film medium wavelength, then in this layer
The red light that the two sides of film reflect back will interfere, to cancel out each other, according to the conservation of energy, this Shu Hongguang is
Completely extend across the antireflective coating, that is to say, that the transmissivity of red light nearly reaches absolutely, and other light is saturating
Penetrating rate opposite can then weaken.
