Specific embodiment
The embodiment of the present invention is described below in detail, examples of the embodiments are shown in the accompanying drawings, wherein from beginning to end
Same or similar label indicates same or similar element or element with the same or similar functions.Below with reference to attached
The embodiment of figure description is exemplary, and for explaining only the invention, and is not considered as limiting the invention.
In one aspect of the invention, the invention proposes a kind of electrochromic devices.According to an embodiment of the invention, ginseng
Fig. 1 is examined, which includes: first electrode layer 100, the second electrode lay 300, electrochromic layer 200 and control electricity
Road 10.Wherein, electrochromic layer 200 is between first electrode layer 100 and the second electrode lay 300, control circuit 10 respectively with
First electrode layer 100 is connected with the second electrode lay 300, and the connection site of first electrode layer 100 and control circuit 10 is A, and second
The connection site of electrode layer 300 and control circuit 10 is B, positive throwing of the connection site A and B in 100 place plane of first electrode layer
Shadow is not overlapped.When applying voltage to the electrochromic device by control circuit as a result, due to control circuit and two electrode layers
Connection site be not overlapped, electrode layer close to connection site region and the resistance far from connection site region is different, thus
So that the electric field strength between the electrode layer of two, connection site region and two electrode layers far from connection site region it
Between electric field strength it is different so that electrochromic device is deeper in the color close to connection site region, far from connection position
The color in point region is shallower, forms the color changeable effect of gradual change, so that having using the shell of the electrochromic device bright and colourful
Appearance.
In order to make it easy to understand, electrochromic device according to an embodiment of the present invention is briefly described first below:
According to an embodiment of the invention, being carried out by the positional relationship to control circuit and the connection site of two electrode layers
Design, it is different further according to the resistance of electrode layer different zones, so that between two electrode layers close to connection site region
Electric field strength, the electric field strength between two electrode layers far from connection site region is different, so that electrochromism device
Part is deeper in the color close to connection site region, and the color far from connection site region is shallower, forms the color changeable effect of gradual change.
Below according to specific embodiments of the present invention, each structure of the electrochromic device is described in detail:
According to an embodiment of the invention, first electrode layer 100 and the second electrode lay 300 are separately by electrically conducting transparent material
Material is formed.After electrochromic layer is driven generation color change by voltage as a result, transparent first electrode layer and second can be passed through
Electrode layer shows the color of electrochromic layer.According to a particular embodiment of the invention, first electrode layer 100 and the second electrode lay
300 are separately formed by tin indium oxide (ITO).
Directly it is connected with electrode layer according to an embodiment of the invention, control circuit can be, at this time control circuit and electrode
The tie point of layer is respectively connection site A and B, and the sheet resistance of even electrode layer is smaller, and the resistance of electrode layer different zones also can
It has differences, since control circuit and the connection site of two electrode layers be not be overlapped, so it is applied to the voltage on electrode layer,
All have voltage drop on the direction on the different sides of electrode layer so that the electrochromic device close to connection site region and
Color changeable effect far from connection site region can be different, and by gradual change is presented to the region far from connection site close to connection site
Effect.
According to an embodiment of the invention, in order to enhance the gradient color effect of electrochromic device, first electrode layer 100 and
The thickness of two electrode layers 300 can separately be 50-120nm.Since the thickness of electrode layer is smaller, so that the side of electrode layer
Hinder it is larger, as a result, by control circuit to the electrochromic device apply voltage when, electrode layer on the direction along different sides
With biggish voltage drop, and two electrode layers and the orthographic projection of the connection site of control circuit be not be overlapped, so that electrochromism
Device is deeper in the color close to control circuit region, and the color far from control circuit region is shallower, enhances electrochromic device
Gradient color effect so that using the electrochromic device shell have bright and colourful appearance.
According to an embodiment of the invention, first electrode layer 100 and the second electrode lay 300 can be rectangle face electrode,
At least one of first electrode layer 100 and the second electrode lay 300 have on the length or width direction of rectangle face electrode
The thickness changed in gradient.Electrode layer can have different sheet resistances in different thickness areas, and the sheet resistance of electrode layer is also in as a result,
Gradient further increases the inhomogeneities of each region voltage distribution on two electrode layers, so that driving electrochromic layer becomes
The inhomogeneities of the electric field of color increases, the gradient color effect that enhancing electrochromic device is presented.Change about electrode layer sheet resistance
Gradient be not particularly limited, as long as the gradient color effect that electrochromic device is presented can be enhanced, art technology
Personnel can be designed as the case may be.

300 and control circuit 10 connection site B, the not ipsilateral of the electrochromic device can also be located at, and can be located at
The different side edge of any two of the electrochromic device.The electrochromic device, which can show, as a result, is provided with connection
The two sides color in site is deeper, the shallower gradient color effect of the field color far from connection site.For example, reality according to the present invention
Example is applied, connection site A and connection site B can be located at the left and right side of the electrochromic device (in such as Fig. 3
(a)) or connection site A and connection site B can be located at the upper side and lower side of the electrochromic device (in such as Fig. 5
(a)) or connection site A and connection site B can be located at the left side of the electrochromic device and upside (does not show in figure
This kind of situation out), then connection site A and connection site B can be located at the left side and downside of the electrochromic device
(this kind of situation is not shown in the figure), this is no longer going to repeat them, and those skilled in the art can gradient color according to actual needs
Effect is designed.
The not ipsilateral specific location of the electrochromic device is located at not by spy about connection site A and connection site B
It does not limit, those skilled in the art can be designed as the case may be.For example, according to an embodiment of the invention, the first electricity
The connection site A, the connection site B with the second electrode lay 300 and control circuit 10, first of pole layer 100 and control circuit 10
