At influence of the resistance to electrochromic device voltage of electrode layer can be ignored, the voltage of electrochromic device mainly by
The influence of circuitous resistance.According to an embodiment of the invention, due to the resistivity of above-mentioned transparent conductive material (for example, tin indium oxide)
Compared with conventional metallic conductor it is larger, therefore when the length long enough of circuit, with the change of L/W values in above-mentioned formula (1)
Change, then the resistance R values of circuit 600 can also significantly change.Therefore, according to formula (1) to the width W and length L of circuit 600
It is designed so that the different position of L values has different resistance in circuit 600, i.e., the resistance of entire 600 each sections of circuit is not
Together, and circuit 600 is by more 10 connection electrode layers of transparent lead (including first electrode layer 200 and the second electrode lay 400), from
And make the voltage drop being applied on electrode layer larger.According to an embodiment of the invention, the more of circuit 600 and electrode layer are connected
The transparent lead 10 of root, which is not that L values are equal from circuit 600, a little draws, therefore the reality at different transparent leads 10
Voltage value is simultaneously unequal, and then the voltage for being actually applied to each region of electrode layer can be made different, the different electricity of counter electrode layer
The electrochromic material of intermediate pressure section will present the color under corresponding voltage so that the electrochromic device can present a variety of simultaneously

According to an embodiment of the invention, with reference to figure 2, the middle part of circuit 600 is (in length direction L as shown in Figure 2
Point C) there is control source port 30.After applying voltage to circuit 600 from control source port 30, since circuit 600 passes through
More transparent leads 10 are electrically connected with first electrode layer 200 so that first electrode layer 200 is divided by boundary of the dotted line where C points
For two parts, and above-mentioned two part is that parallel relationship is in other words actually applied to first electrode layer 200 above-mentioned two
The voltage divided is the voltage that external circuit applies.According to an embodiment of the invention, circuit 600 is divided into two using C points as symmetric points
Point, the resistance of each section of above-mentioned two parts can be obtained according to formula (1) using the width and each section of length computation of circuit 600
Go out, wherein above-mentioned two-part longest segment length is L/2 (as shown in Figure 2), and the above-mentioned two-part resistance of circuit is from C as a result,
Point position starts respectively that arrow direction gradually increases along figure, and above-mentioned two-part resistance is symmetrical as symmetric points using C points,
Voltage to be actually applied to first electrode layer is symmetric using the dotted line where C points as boundary, and the voltage of symmetrical region
Successively decrease successively so that the different region of multiple and symmetrical voltage is formed between first electrode layer and the second electrode lay, to make
Obtaining electrochromic device not only multiple color can be presented simultaneously but also may be implemented symmetrically to change colour.It should be noted that " symmetrical region
Voltage " refer to electrode layer using the dotted line where C points as the voltage in a region in two regions that boundary divides.
The concrete numerical value of width W and length L about circuit are not particularly limited, if electrode layer can realize it is larger
Voltage drop, those skilled in the art can be designed as the case may be.For example, according to an embodiment of the invention,
The width W of circuit 600 can be 0.5-5mm, and length L can be 1-20cm.It should be strongly noted that above-mentioned " realize larger
Voltage drop ", refer in particular to the voltage drop on circuit 600, it is sufficient to which satisfaction enables the electrochromism functional layer of symmetrical region at least can be in
Existing two kinds of colors：Electrochromic material in the electrochromism functional layer of symmetrical region can be in specific voltage range
Now specific color, when voltage range difference, the color that can be presented is also different.Above-mentioned " larger voltage drop " is as long as can cross over
At least one specific voltage section of electrochromic material.
According to a particular embodiment of the invention, when the width W of circuit 600 is 1mm, the resistance variations of circuit 600 are 1
Ω/cm, circuit 600 have the voltage drop of 0.2V every the length of 1cm along its length, thus, it is possible to by circuit 600 regard as by
The section of multiple 1cm length is constituted, after applying a certain voltage to electrochromic device 1000 from the middle part of circuit 600, circuit
600 two parts formed as symmetric points using C points, each section since C points respectively along Fig. 2 in arrow direction can have
The voltage drop of 0.2V, so that the voltage for being actually applied to electrode layer is symmetric and the voltage of symmetrical region is passed successively
Subtract.According to a particular embodiment of the invention, first electrode layer 200 is formed by transparent conductive material, and 200 side of first electrode layer
Be provided with circuit 600, the second electrode lay 400 is formed by metal material, when from control source port 30 to circuit 600 apply definite value
The voltage of voltage (such as+2V), when the second electrode lay 400 applies voltage (such as 0V) of fixed numbers, since circuit 600 is with C points
Boundary respectively along its length on each section can have the voltage drop of 0.2V, after oversampling circuit 600, by multiple transparent leads
The different zones of output to first electrode layer 200 are also corresponding with different positive voltages and voltage is symmetric, so that real
Border is applied to the voltage of each zonule in electrode layer symmetrical region (two regions to be marked off by boundary's dotted line in the middle part of circuit)
Also the voltage drop with 0.2V, for example, with reference to figure 5, the voltage in (c1), the region (c2) is respectively 2V, the electricity in (b1), the region (b2)
Pressure is respectively 1.8V, and the voltage in (a1), the region (a2) is respectively 1.6V, in other words, (c1) and (c2), (b1) and (b2),
(a1) it is symmetric respectively as symmetry axis using the dotted line where C points with (a2).Since 400 each region of the second electrode lay is not present
Voltage drop therefore can shape along each region that 600 length direction of circuit divides between first electrode layer 200 and the second electrode lay 400
At different electric fields, for example, the voltage between (c1), corresponding two electrode layers in the region (c2) is 2V, (b1), region pair (b2)
Voltage between two electrode layers answered is 1.8V, and the voltage between corresponding two electrode layers in (a1), the region (a2) is 1.6V,
So that different colors is presented in the electrochromism functional layer in corresponding above-mentioned different voltages region under corresponding voltage.
As previously mentioned, in certain voltage range, specific color can be presented in electrochromic material.Therefore, work as difference
Voltage between section is too small, when being not enough to the voltage range that cross-domain electrochromic material changes colour, even if then electrode layer is each
The voltage in region simultaneously differs, and electrochromic material can not be enabled to show different colors.As previously mentioned, the number of voltage drop
Value, increases with the growth of the length L of circuit.Therefore, in order to ensure electrochromic material in the area of electrode layer voltage minimum
Realize discoloration, in the present embodiment, the length L of circuit 600 in domain (for example, farthest region of distance C points on circuit length direction)
Can be 20cm.In other words, the length L/2 of 600 counter electrode layer symmetrical region of circuit can be 10cm.It is according to the present invention
The resistance of embodiment, circuit 600 is changed according to the cooperation of its width and length, two divided as symmetric points using C points
The change process of the resistance divided is progressive formation, and therefore, the voltage for being actually applied to symmetrical region on electrode layer is also gradually
Become, the color that 1000 symmetrical region of electrochromic device is finally presented also is the color of gradual change.

One electrode layer 200, and the distance between adjacent two transparent leads 10 (d as shown in Figure 2) are 1-10mm, as a result, may be used
So that electrode layer has good be electrically connected with circuit.According to a particular embodiment of the invention, adjacent two transparent leads 10
The distance between can be 1mm.Since the length of transparent lead is shorter, so the resistance of transparent lead is to electrochromic device electricity
The influence of pressure is smaller, and thus the constituent material of transparent lead is not particularly limited, as long as with higher transparency and well
Electric conductivity, those skilled in the art can be designed as the case may be.For example, according to an embodiment of the invention,
Transparent lead 10 can be formed by tin indium oxide.
