Embodiment
Referring to Fig. 1, Fig. 2, Fig. 3 and Fig. 4, this active switching regulator 3-D display eyeglass comprises front glass substrate 1, back glass substrate 2, outer cofferdam 3, preceding transparency electrode 4, back transparency electrode 5, coloured nonpolar oil droplet 8, at least two hydrophilic medium layers 9, at least two hydrophobic medium layers 7 and at least two interior cofferdam 13; Described outer cofferdam 3 is arranged between front glass substrate 1 and the back glass substrate 2 and forms the chamber 6 of sealing, and the quantity of chamber 6 is relevant with the eyeglass size, and each chamber 6 is as a junior unit, and its area must not be greater than 1mm*1mm; Preceding transparency electrode 4, back transparency electrode 5, hydrophilic medium layer 9 and hydrophobic medium layer 7 and coloured nonpolar oil droplet 8 are positioned at chamber 6;
The upper surface 6-1 that first transparency electrode 4 is arranged on chamber 6 goes up and covers whole upper surfaces of chamber 6, and the lower surface 6-2 that back transparency electrode 5 is arranged on chamber 6 goes up and whole lower surfaces of covering chamber 6;
Closely arrange between the cofferdam 13 in described and form the matrix form arrangement and cover all surfaces that hydrophobic medium layer 7 is positioned at chamber 6.The cross section in cofferdam 17 can be rectangle, square, rhombus, regular hexagon in described, perhaps can also for other can be seamless spliced polygon.It in the present embodiment square.
Described coloured nonpolar oil droplet 8 is that the carbon black of 5～1000 nanometers or carbon nano-tube are dispersed in the silicone oil and constitute by particle diameter.Described front glass substrate 1 and back glass substrate 2 are the clear sheet or the film of 0.01～3 millimeter glass, polycarbonate, polymethacrylate or polyphenyl dioctyl phthalate glycol ester for thickness.Transparency electrode 4 and back transparency electrode 5 are the tin indium oxide or the ZnO transparent film of 10～1000 nanometers for thickness before described.Hydrophilic layer can adopt the AZ4620 photoresist to make, and thickness is 3～6 microns.The hydrophobic medium layer can adopt Teflon to make, and thickness is 0.6～0.8 micron.The cofferdam can adopt dimethyl silicone polymer (PDMS) frame to make, and thickness is 1～6 millimeter.
The concrete principle of work of present embodiment is as shown in Figure 3 and Figure 4: between current transparency electrode and the back transparency electrode not during making alive, an oil droplet that has color is that coloured nonpolar oil droplet will be tiled between water and the hydrophobic medium laminar surface automatically, this is because under micro-meter scale, and the surface tension on hydrophobic layer surface and hydrophilic layer surface satisfies equation 1 and 2 respectively

Wherein γ is a surface tension; Subscript w, o, i and iw represent water, oil, hydrophobic medium laminar surface and hydrophilic medium laminar surface respectively.Therefore, at hydrophilic medium layer and place, hydrophobic medium bed interface, water will directly contact with the hydrophilic medium laminar surface, thereby form water-oil interface as shown in Figure 3.When visible light incided the back transparent glass substrate from eyeglass the place ahead, the part spectrum of visible light was absorbed by oil droplet, and transmitted spectrum mainly concentrates near the oil droplet color of light spectral coverage, and this moment, eyeglass showed as " pass " state.As depicted in figs. 1 and 2: when applying certain voltage between current transparency electrode and the back transparency electrode, balance is originally broken.Impressed voltage will cause capillary variation between oil droplet and the hydrophobic medium layer, and its change amount is γ
EwCan try to achieve by the Lippmann formula.Along with the increase of impressed voltage, when satisfying

The time, oil droplet can not be paved with whole eyeglass fully, and transparent water will arrange the part oil droplet, directly contacts with the hydrophobic medium layer, thus formation water, oil droplet and hydrophobic medium layer three phase boundary as shown in Figure 1.Along with the increase of voltage, in order to keep system's energy equilibrium, the three-phase contact angle θ of water droplet can diminish, and it is big that water droplet and hydrophobic medium layer contact area become, and oil droplet is heaved.At this moment, when visible light incided the back transparent glass substrate from the eyeglass front, visible light directly transmitted eyeglass by back transparent glass substrate, transparent water and the preceding transparent glass substrate that does not have oil droplet to cover, and this moment, eyeglass was " opening " state.
Referring to Fig. 5, adopt the active switching regulator 3-D display glasses of above-mentioned active switching regulator 3-D display eyeglass as eyeglass 11, comprise mirror holder 10, isochronous controller 15 and be installed on the mirror holder and be used to receive the infrared remote receiver 12 that infrared signal that infrared emittance 16 sent is controlled the size that is applied to the voltage on the eyeglass 11 simultaneously, eyeglass 11 is installed on the mirror holder 10, and isochronous controller 15 is electrically connected with infrared emittance 16 and is used to control infrared emittance 16.
The concrete principle of work of this active switching regulator 3-D display glasses shows the left eye of 3-D view or video correspondence or the image or the video of right eye respectively as shown in Figure 5 frame by frame on the display 14; Control the infrared emittance 16 that is installed on the display 14 by isochronous controller 15, image or video that present frame shows are left-eye image, then infrared emittance 16 sends corresponding pulses and gives the infrared signal receiver of installing on the mirror holder 10 of active switching regulator 3-D display glasses 12, infrared signal receiver 12 is according to the signal controlling active switching regulator 3-D display eyeglass 11 that receives, respectively left and right sides eyeglass is applied correspondent voltage, make it to open or close.If what infrared signal receiver 12 received is the left eye signal, then left eyeglass lens is applied positive voltage, the right eye eyeglass applies 0 voltage, and corresponding eye left eyeglass lens is opened, and the right eye eyeglass closes; Otherwise image or video that present frame shows are eye image, and then to then left eyeglass lens being applied 0 voltage, the right eye eyeglass applies positive voltage, and corresponding eye right eye eyeglass is opened, and left eyeglass lens closes; So circulation repeats, and makes current time left eye or right eye accept the picture material of left eye or right eye, and the picture material that next moment right eye or left eye receive right eye or left eye realizes 3-D display with this.
