Multiple second sources 71.Each second source 71 is electrically connected with corresponding second photochromic elements 61, for corresponding second
Photochromic elements 61 provide two kinds of different voltages values voltage source so that second photochromic elements 61 be powered after can become white or
Person is transparent.
The optical properties (reflectivity, transmitance, absorptivity etc.) of first photochromic elements 41 and second photochromic elements 61
Stablize under the action of extra electric field, reversible color change；The possibility of reversal of color and transparency is shown as in appearance
Change.
Specifically, as shown in figure 4, first photochromic elements 41 include stack gradually setting the first transparent base layer 401,
First transparency conducting layer 402, electrochromic layer 403, electrolyte layer 404, ion storage 405, the second transparency conducting layer 406,
And second transparent base layer 407.In the present embodiment, first transparent base layer 401 and second transparent base layer 407 by
Glass is made；First transparency conducting layer 402 and second transparency conducting layer 406 are made of tin indium oxide；The electrochromism
Layer 403 is made of electrochromic material；The electrolyte layer 404 is made of conductive material, such as includes that lithium perchlorate, perchloric acid are received
Deng solution or solid electrolyte material；The ion storage 405 is by the electricity opposite with the discoloration of the electrochromic layer 403
Off-color material is caused to be made.Such as：The electrochromic layer 403 is using anodic oxidation off-color material, then the ion storage 405 can
Using cathodic reduction off-color material.
The operation principle of first photochromic elements 41 is：When in first transparency conducting layer 402 and second electrically conducting transparent
When adding certain voltage between layer 406, acted on since the electrochromic layer 403 is made of electrochromic material, and in voltage
Lower generation redox reaction, color change.In the electrochromic layer 403 redox occurs for the ion storage 405
Play the role of storage corresponding counter ion when reaction, keeps whole system charge balance.The ion storage 405 is played and is somebody's turn to do
The effect of 403 color addition of electrochromic layer or complementation.That is, first photochromic elements 41 are issued in DC Electric Field
Raw electrochemical redox reaction, obtains or loses electronics, the color of first photochromic elements 41 is made to change.
Second photochromic elements 61 and the structure of first photochromic elements 41 are essentially identical, and difference is：Second change
The material of the electrochromic layer of color component 61 is different from the material of the electrochromic layer of first photochromic elements 41.
The controller 90 is electrically connected with the microprocessor 10 and the switch 30, and whether opened according to the backlight module 20 and
The brightness value is applied to the voltage of first photochromic elements 41 and controls the second source mould to control first power module 50
The voltage that block 70 is applied to second photochromic elements 61 is changed according to the brightness value of the corresponding pixel, makes the display
100 show the image.Specifically, when the switch 30 is in first state, indicate that the backlight module 20 is opened, at this point, the control
Device 90 processed controls the second photochromic elements 61 energization corresponding with multiple white pixel and becomes white, with multiple white pixel pair
The first photochromic elements 41 energization answered becomes transparent；Meanwhile the controller 90 also controls corresponding with multiple black picture element
The energization of two photochromic elements 61 becomes transparent, and the first photochromic elements 41 energization corresponding with multiple black picture element becomes black.When
When the switch 30 is in the second state, indicate that the backlight module 20 is closed, at this point, the controller 90 control and multiple white picture
The corresponding energization of second photochromic elements 61 of element becomes white, and the first photochromic elements 41 corresponding with multiple white pixel, which are powered, to be become
At transparent, while the controller 90 also controls the second photochromic elements 61 energization corresponding with multiple black picture element and becomes transparent,
The first photochromic elements 41 energization corresponding with multiple black picture element becomes black.
The course of work of the display 100 is as follows：When external environment light is inadequate, user opens the backlight module
20, observe the image using the backlight module 20.The second photochromic elements 61 energization corresponding with multiple white pixel becomes
It is bright, while the first photochromic elements 41 corresponding with multiple white pixel energization becomes transparent so that the backlight module 20 is sent out
Light pass through the first photochromic elements 41 corresponding with multiple white pixel and corresponding second photochromic elements 61, make the display
Device 100 is displayed in white pixel.The second photochromic elements 61 energization corresponding with multiple black picture element becomes transparent, while more with this
The corresponding energization of first photochromic elements 41 of a black picture element becomes black so that the light that the backlight module 20 is sent out passes through and this
After corresponding second photochromic elements of multiple black picture elements 61, absorbed by corresponding first photochromic elements 41, no light enters use
The eyes at family make the display 100 show black picture element.Multiple white pixel and multiple black picture element form the image.
When external environment is bright and clear, user closes the backlight module 20.The image is observed using ambient light.With this
The corresponding energization of second photochromic elements 61 of multiple white pixels becomes white, while corresponding with multiple white pixel first becomes
The energization of color component 41 becomes transparent, and the light of external environment is anti-by second photochromic elements 61 corresponding with multiple white pixel
It penetrates, the display 100 is made to show multiple white pixel.The second photochromic elements 61 corresponding with multiple black picture element, which are powered, to be become
At transparent, while the first photochromic elements 41 corresponding with multiple black picture element energization becomes black, and the light of external environment is worn
It crosses after the second photochromic elements 61 corresponding with multiple black picture element, is absorbed by corresponding first photochromic elements 41, without light
Line makes the display 100 show multiple black picture element into the eyes of access customer.Multiple white pixel and multiple black picture
Element forms the image.
Compared with prior art, display 100 of the invention, when the light of external environment is inadequate, user can
The backlight module 20 is opened, to observe the image under the light that the backlight module 20 is sent out；When the light of external environment fills
When sufficient, user can close the backlight module 20, to observe the image under extraneous ambient light, therefore can effectively save electricity
Energy.
