The part of the surface of the first transparency conducting layer 200 is covered, in other words, by the way that electrochromic layer 300 is arranged, entire shell can be made
With hitting color and color changeable effect, can also the part of the surface of only shell have and different hit color and color changeable effect, this field
Technical staff can according to need carry out flexible design.Specifically, at least two electrochromism in multiple electrochromism blocks 310
Block 310 is disposed adjacent, and the side wall for the electrochromism block 310 being disposed adjacent contacts with each other.Two electroluminescent changes being disposed adjacent as a result,
There is no gap between color lump 310, can make to hit that colour contrast effect is more significant, the expressive force of product is stronger, also, when multiple electroluminescent
When the block that changes colour covers all surfaces of the first transparency conducting layer 200, multiple electrochromism blocks 310 are disposed adjacent, and are contacted with each other,
Can make entire shell all have it is good hit color and discoloration, the appearance power of product is more preferable.
Specifically, the electrochromic layer 300 of shell 1000 includes two electrochromism block 310A and 310B with reference to Fig. 2,
The electrochromism color of two electrochromism block 310A and 310B is different, and electrochromism block 310A and electrochromism block 310B are adjacent
Setting, more specifically, all surfaces of electrochromism block 310A and electrochromism block 310B the first transparency conducting layer 200 of covering,
So as to which so that shell 1000 generates the color hitting effect of two kinds of colors, and the color of the shell 1000 can also be by voltage side
It changes to the change with size, generates the effect that different colours hit color, visual impact is stronger, and product expressive force is more preferably.
Specifically, electrochromism block 310A can be blue, and electrochromism block 310B can be red under conditions of voltage is 1.4V
Color, so that in this state, blue and red color hitting effect is presented in shell 1000；When the size for changing voltage, make voltage-
When 0.8V, the color of electrochromism block 310A becomes purple, and the color of electrochromism block 310B becomes yellow, thus in the state

Phenomenon, so as to improve the service life of the shell.Specifically, the ion in electrolyte layer 400 can be with electrochromic layer
Doping or dedoping occur for the organic electrochromic material in 300, so that color change occurs for electrochromic layer 300.Tool
Body, when applying certain positive voltage to the first transparency conducting layer 200 and the second conductive layer 600, in electrochromic layer 300
Organic electrochromic material oxidation reaction occurs, lose electronics, the electron transfer lost in electrochromic layer 300 to first is thoroughly
In bright conductive layer 200, the anion in electrolyte layer 400 is moved in electrochromic layer 300, in electrochromic layer 300
Organic electrochromic material adulterates, while the cation in electrolyte layer 400 can move in ion storage layer 500, and
Electron transfer in second conductive layer 600 is into ion storage layer 500, so that color change occurs for electrochromic layer 300, simultaneously
So that whole system keeps charge balance.Specifically, when not applying voltage to shell, the color of the presentation of electrochromic layer 300
The as color of itself extinction, organic electrochromic material hair after applying positive voltage to shell, in electrochromic layer 300
Raw oxidation reaction, substance itself change, the spectrum change of absorption, so that another color be presented.Specifically, when to generation
When shell after color change applies negative voltage, reduction reaction can occur for the organic electrochromic material in electrochromic layer 300,
The ion and electronics of migration will be moved back in its original film layer, to become the original color of shell again.
Specifically, the thickness of electrolyte layer 400 is thicker.Thus, it is possible to by electrolyte layer by electrochromic layer and from
Sub- storage layer separates, so that the negative ions of migration will not converge quickly, while can separate the first transparency conducting layer and the
Electronics in two conductive layers guarantees the stability of electrochromic layer discoloration.Specifically, the thickness of electrolyte layer 400 can be 50-
300μm.Thus, it is possible to further increase the stability of electrochromic layer discoloration.By the thickness design of electrolyte layer 400 above-mentioned
In range, breakdown etc. is bad caused by electrolyte layer 400 can be prevented excessively thin, and electrolyte layer 400 can be prevented blocked up
Caused by the bad problem such as the electrochromism time is longer, shell integral thickness is thicker.

Color change.Specifically, certain color is presented in the ion in ion storage layer 500, when the thickness of ion storage layer 500 is thicker
When, the color of ion storage layer 500 is deeper, and when voltage is not added in shell, the color of ion storage layer 500 will penetrate electrolyte
Layer 400, electrochromic layer 300, the first transparency conducting layer 200 and first substrate 100, so that a degree of face is presented in shell
Color influences the color changeable effect of shell.The thickness of ion storage layer can be rationally designed according to above-mentioned two condition as a result,
Specific thickness value about ion storage layer is not particularly limited, as long as can make electrochromic layer that color change and entire occur
Shell relatively transparent color changeable effect for not influencing shell when not applying voltage.For example, specifically, ion storage layer
500 pure solid content thickness can be 100-700nm.Specifically, the pure solid content thickness of ion storage layer 500 can be 100-
300nm, or be 600nm or so.It will be appreciated to those of skill in the art that ion storage layer 500 is by containing ion film layer

, the second substrate 700 can be to be formed by plastic film flexible, for example, can be polyethylene terephthalate film
Or polycarbonate membrane.The thickness for the second substrate 700 that flexible material is formed as a result, is smaller, and the whole thick of shell can be thinned
Degree, and the efficiency for plating on flexible material the second conductive layer 600 is higher, cost is relatively low.Specifically, when the second conductive layer 600 by
It, can be in the ink or the different texture of setting of 700 surface printing different colours of the second substrate when transparent conductive material formation
Effect to block the component in electronic equipment, and can further enrich the effect that shell is finally presented.Specifically, second
Conductive layer can be designed as having lesser sheet resistance, to guarantee that it, with good electric conductivity, reduces the consumption of energy, at this time
The transparency of two conductive layers can be not required.Specifically, the second conductive layer 600 can also be opaque conductive material shape
At specifically, can be the metal materials such as aluminium, copper.When the second conductive layer is formed by metal material, one side metal material tool
There is good electric conductivity, another aspect metal material is opaque material, can block movement when voltage is not added in shell as a result,
