Up-protective layer, lower protective layer should select high printing opacity, the good material of strength ratio.Such as glass or organic material.If use flexible clear materials as protective seam, then the display device can make flexibility, freely can cutting.
Content to display is projected by up-protective layer and enters.
Up-protective layer is coated with double-layer films, is respectively conduction film plating layer and photosensitive layer.The order of plated film is: first carry out conductive material plated film, then carries out photochromics plated film.Lower protective layer only has conduction film plating layer.If ion conductive layer and ion storage adopt solid material, then lower protective layer can be glass.The technique of plated film does not do requirement, only otherwise destroy protective seam.
The material of conduction film plating layer can be the tin oxide (FTO) of doped with fluorine, tin oxide or indium tin oxide target etc., and the material of photosensitive layer can be the photoresistance materials such as cadmium sulfide, also can be photovoltaic cell material, as dye sensitization material.
The material that electrochromic layer uses is electrochromic material, can select organic electrochromic material (as purpurine class) or inorganic electrochromic material (as tungstic acid, titania etc.).When there being enough voltage to be added on this one deck, and when causing enough electric currents by this one deck, will there is color change in electrochromic material, demonstrate the content needing display.
Ion conductive layer, also referred to as dielectric substrate, object is delivered current between electrochromic layer and ion storage.Can be liquid state, colloidal sol or solid-state electrolyte, such as carbonic allyl ester, ethylene carbonate ester and lithium perchlorate, the composite material of lithium hexafluoro phosphate, lithium tantalate etc.
Ion storage, object is when electrochromic layer reacts, and store the gegenion produced, with balancing charge, ensure when removing external power source, the content of display can not disappear.Such as nickel oxide, cerium oxide, vanadium pentoxide, Prussian blue, polyaniline, azophenlyene class etc.
Use the invention described above device to carry out the method shown, step is as follows

2, disconnect driving voltage, now whole display device maintains whole color change state;
3, will need the up-protective layer of contribute content display device of display with external light source, now the content that project according to external light source of photosensitive layer, the part be not illuminated maintenance high resistance state, the part be illuminated becomes conduction state;
4, access reverse drive voltages, now display device will demonstrate the content needing display;
5, disconnect driving voltage, close external light source, now display device will maintain the content needing display.
Apparatus of the present invention are in conjunction with electrochromism technology, and photoelectric effect technology, realizes a kind of unprecedented display technique, possess following characteristics:
1, energy-conservation
Only need the power consumption when change displaying contents, at ordinary times without the need to power supply, i.e. displaying contents self-sustaining.Even if when change displaying contents, power consumption is also very low, approximately 100 watts every square metre, and this process can complete less than one minute, be applicable to very much solar powered.
2, safeguard simple
Only need, by needing the content of display to project on this device and being energized (being called galvanochemistry exposure and electricity development), required content to be shown on this device, need not display device be contacted, driving circuits that also need not be complicated.Its content can be preserved for a long time, keeps without the need to energising.
3, manufacture simple, cost is low
Critical process is large-area coating film technique, compares LCD and conventional electrochromic display technique, and photoetching technique that need not be accurate, yield rate is high.Compare LED technology, need not complicated display circuit and feed circuit.
4, structure is simple, uses flexibly
Basic structure is double shielding layer, and inside is photosensitive plated film and conductive layer plated film, electrochromic material, ion-conductive material, extraction electrode.When protective seam made by the suitable material of use, and when using cell structure, this display device can be cut arbitrarily and not affect Presentation Function.
Present invention incorporates electrochromism technology and photoelectric effect technology.These two technology have been all the technology of mature and reliable.
Electrochromism refers to that some material (such as: tungstic acid, viologen class material etc.) is under electric field action, the characteristic that the optical signatures such as color, transmittance, reflectivity change.This technology can be used for display at present, but because it does not have clear superiority, widely use so have no.
Photoelectric effect refers to that some material (most of semiconductor material, cadmium sulfide etc.) is under the condition having illumination and unglazed photograph, the characteristic that resistivity changes.According to this characteristic, the device (mainly photoresistance) issuing as before raw resistance variations according to ambient light can be made.
Had technology that photoresistance is placed on electrochromic device outside, thus realize can according to the device of extraneous light intensity automatic color-changing, but can only overall variable color, effective content cannot be shown.
Main thought of the present invention is joined in electrochromic display device by one deck photochromics.Traditional electrochromic display device cannot break away from precision photolithography technology, and therefore also have the shortcoming same with LCD, namely extraction electrode is many, and product defects is many, controls complicated.Once one deck photochromics is joined in electrochromic display device, then needing the content of display to project in display device, then the resistance of this one deck photochromics will change according to the bright-dark degree of projection content, dark position, resistance is still very large, this zone current is very little, cannot reach the degree of electrochromic material conversion; Bright position, resistance decreasing, this zone current increases, and electrochromic material is changed.Finally, the content shown by electrochromic display device just can be determined by the pattern projected in display device.

Fig. 3 is that the present invention uses process flow diagram;
Fig. 4 is that the present invention uses schematic diagram.
Embodiment
Below in conjunction with drawings and Examples, technical solution of the present invention is specifically described.
As shown in Figure 1; display device of the present invention; comprise up-protective layer and the lower protective layer of printing opacity; two membranes is coated with below up-protective layer; be conduction film plating layer and photosensitive layer successively, described lower protective layer is coated with conduction film plating layer, photosensitive layer has electrochromic layer, ion conductive layer and ion storage downwards successively; conduction film plating layer on upper and lower protective seam connects extraction electrode, connects for driving power.
As can be seen from Fig. 1, except photosensitive layer, all the other structures and common electrochromic display device seem and indistinction, but in fact, there is this one deck photosensitive layer just, this device is just made only to need two electrodes, and unconventional electrochromic display device (ECD) needs multiple electrode, exactly because also this one deck photosensitive layer, just make the display mode of this device and display device all at present completely different, the electrode that it does not re-use change drives, but is undertaken by outside light source irradiation " galvanochemistry exposure ", be similar to the exposure imaging of sensitive film.
Fig. 1 also have expressed when needing situation when showing left side half and the right half different colours in this display device:
First use external light source (such as projector) to need the pattern of display to up-protective layer projection, what represent in Fig. 1 is that the left side is unglazed, and there is light on the right.Now, the photosensitive layer of left one side of something is not because be subject to illumination, and therefore resistance is very large; The photosensitive layer of right one side of something is owing to being subject to illumination, and resistance reduces.Now between extraction electrode 9 and extraction electrode 10, add driving voltage, then electric current only can comprise electrode, photosensitive layer, electrochromic layer and ion conductive layer and ion storage by right half of current channel 12() thus cause the electrochromic material variable color at this place, and the part on the left side due to loop resistance very large, electric current is very little, is not enough to cause electrochromic material variable color.Like this, this display device just shows the content consistent with projective patterns.
Now disconnect the external drive power supply that is connected on 9 and 10 extraction electrodes, and close external light source, then this display device can keep the pattern that just now generated, can not disappear.
If protective seam uses flexible material (such as PET), and between protective seam, be divided into independently grid, sealed to each other between grid, then can make the display device arbitrarily can cut, bend.But because the isolated part between sub-box does not have electrochromism and electrolyte, therefore these isolated parts cannot show any content.Because isolated part area occupied is very little, therefore very little on the impact of display effect.As shown in Figure 2.
Preparation embodiment:
Because the display device manufactured may be used for open air, resistance to temperature and the antisum irradiation performance of display device are important, and therefore common liquid electrolyte is not be applicable to very much.Below using glass as protective material, the manufacturing process that the concise and to the point all solid state mode describing a kind of display device realizes:
1, main raw material(s) and equipment:
TCO glass, CdS, WO
3, LiTaO
3, NiOx, ITO, conductive metal foil, simple glass.
Vacuum coating equipment.
2, key step
First in the following order, by layers of material plated film on TCO glass: CdS, WO
3, LiTaO
3, NiOx, ITO,
With conductive metal foil, TCO/ITO electrode is drawn respectively again;
Simple glass is placed on ITO layer one side, play a protective role, manufacture completes.
Use embodiment:
Use step as shown in Figure 3:
1, whole display device is exposed completely, and adds positive drive voltage.The now complete variable color of display device (content before removing);
2, disconnect driving voltage;
3, will the contribute content display device (galvanochemistry exposure) of display be needed with external light source (such as projector);
4, access reverse drive voltages.Now, display device will demonstrate the content (electricity development) needing display;
5, disconnect driving voltage;
6, close external light source.Now display device will maintain the content needing display.
The coloring voltage of electrochromic device is between 1.2V to 2.0V, and working current is about 2mA every square centimeter.Because photosensitive layer can produce pressure drop, therefore the driving voltage needs of whole display device are corresponding brings up to 5V.Electrochromic material Coloring Time is less than 10 seconds, after power-off, and holding time of information can reach 1 month.Calculate accordingly, the display device of a square area using this technology to manufacture, when displaying contents changes, if to erase original information, institute that fresh information upgrades all takes into account in steps, only need the electric energy consuming 0.83WH, namely less than 0.001 degree of electricity.In after this middle of the month, if its displaying contents remains unchanged, then no longer need power consumption.
Above embodiment will contribute to those skilled in the art and understand the present invention further, but not limit the present invention in any form.It should be pointed out that to one skilled in the art, without departing from the inventive concept of the premise, some distortion and improvement can also be made.These all belong to protection scope of the present invention.
