Background technology
The notion of electrochromism electrochromic proposed in 1961, it mainly utilizes the electrochromism material under the effect that is subjected to extra electric field, will change its absorbability to light, and cause the variation of color and light penetration, and has characteristic reversible and that continue, when promptly electrochromic material being bestowed externally-applied potential, its color can change.For example, bestowed a visible light when the electrochromism structure, the light that electrochromism structure in fact can absorb certain specific wavelength penetrates, and passes the electrochromism structure to prevent excessive light, can be in order to regulate the amount of incident of different wavelengths of light.
Traditional electrochromism structure comprises transparent one first conductive base, an electrochromism layer, a dielectric substrate and one second electrically conducting transparent base material, transparent first conductive base and the second electrically conducting transparent base material are positioned at the outermost of electrochromism structure, dielectric substrate and electrochromism layer then are disposed between transparent first conductive base and the second electrically conducting transparent base material, poor when between transparent first conductive base and the second electrically conducting transparent base material, bestowing a preset potential, just can make electrochromism structural change color, reach default optical characteristics.
Typical transparent first conductive base and the second electrically conducting transparent base material are reached by glass and form at the conductive film of establishing on glass, but also favourable being used in established conductive film as the electrically conducting transparent base material on the plastic material in some special application.The electrochromism layer can organic compound realizes, as purpurine (Viologen) or pyridine (Pyrodine), or realizes for example inorganic transistion metal compound tungsten oxide (WO with inorganic compound
3), molybdenum oxide (MoO
3) or vanadic oxide (V
2O
5).On the other hand, dielectric substrate can be with a solution that has added lithium chloride and perchlorate.According to different optical characteristics, the electrochromism structure can be used intelligent window Smart windows, the anti-high light back mirror Anti-dazzling Rear view Mirrors of automobile, skylight Sun Roofs, static pattern billboard or the digital display Static display Devices in the car or the like as sunlight projectile energy in the conditioning chamber.
Yet in the existing electrochromism structure, the color of its background is transparent, if desire realizes the white or the background of other color, other technical scheme must be arranged.
The utility model content
The utility model provides a kind of can realize the white or the electro-optical structures of the background of other color.
For solving the problems of the technologies described above, the utility model adopts following technical scheme:
The utility model electro-optical structures, it comprises: one first transparent conductive base, one second conductive base, one first electrochromism layer and a composite bed.
The described first electrochromism layer is built and is placed between described first conductive base and described second conductive base; Described composite bed is built and is placed between described first electrochromism layer and described second conductive base.
Described composite bed comprises a plurality of opaque nano particles with color, and this opaque nano particle is a titanium dioxide nano-particle, and opaque nano particle is dispersed evenly in the composite bed.
Described electro-optical structures also comprises a supply unit, connects to be located between described first electrically conducting transparent base material and described second conductive base.The described first electrochromism layer can comprise potassium ion, hydrogen ion or lithium ion.Preferable described electro-optical structures also can comprise one second electrochromism layer, and it is arranged between described composite bed and described second conductive base.The described second electrochromism layer comprises potassium ion, hydrogen ion or lithium ion.
The beneficial effect of the utility model electro-optical structures is described opaque nano particle, can be in order to the background color as an electrochromism structure; When transparent first conductive base and second conductive base are bestowed a preset potential difference, this first or second electrochromism layer of will moving into or move out of the ion in the composite bed then, change the optical characteristics of electrochromic material in the first or second electrochromism layer, make the color of those electrochromism structures therefore produce variation painted or that discolor.
Because the composite bed in the utility model electro-optical structures just is not responsible for the conduction cation, make electrochromic material finish redox reaction, also because composite bed comprises opaque nano particle, but reflection ray makes composite bed have color, is enough to improve the variable color contrast as the reflector, and do not need extra reflector, make and win or the second electrochromism structure can be thinner, and adjacent one another are because of the composite bed in the utility model and electrochromism interlayer, so the contrast of color is higher.
