Pole 10 and second electrode 20 just to region, be partly arranged on the region for just stretching out to region；Can also be such as Fig. 1 (b)
Shown, the first photic deformation layer 30 all sets the region for just stretching out to region, naturally it is also possible to be, the first photic deformation
Layer 30 is provided entirely in just to region (description of the invention accompanying drawing is not illustrated).
4th, first electrode 10 can be formed by transparent material, or the material shape by that can be reflected light
Into.When first electrode 10 is when being formed by the material that can be reflected light, in order to ensure the freedom of the first photic deformation layer 30
End 301 can first electrode 10 and second electrode 20 just to region in move, it will be understood by those skilled in the art that now
First photic deformation layer 30 should at least partly be arranged on the region for just stretching out to region.In order that more light can irradiate
Onto the first photic deformation layer 30, thus the embodiment of the present invention is preferably, and first electrode 10 is transparency electrode.
5th, in order to ensure display unit can be shown, ambient light must be reflected towards people after injecting display unit
Eye, when the energy reflected light of second electrode 20, it is possible to use second electrode 20 is reflected, or, as shown in Figure 2, it is possible to use
The reflecting layer 3 that generator unit 2 is arranged on away from the side of light valve 1 is reflected.
6th, capacitance equation isWherein, d is the distance between first electrode 10 and second electrode 20, and S is
First electrode 10 and second electrode 20 just to area, ε between first electrode 10 and second electrode 20 medium dielectric constant.
It can be seen from capacitance equation, when the medium between first electrode 10 and second electrode 20 is equal with first electrode 10 and second electrode 20
Just to area change when, the electric capacity that first electrode 10 and second electrode 20 are formed also can accordingly change.Specifically,
Medium between first electrode 10 and second electrode 20 and first electrode 10 and second electrode 20 just to area reduce, then the
The electric capacity that one electrode 10 and second electrode 20 are formed reduces, and now first electrode 10 and second electrode 20 are formed with external circuit and put
Electric current；Medium between first electrode 10 and second electrode 20 and first electrode 10 and second electrode 20 just to area increase
Greatly, then the electric capacity increase that first electrode 10 and second electrode 20 are formed, now first electrode 10 and second electrode 20 are returned with outside
Road forms charging current.
The embodiment of the present invention provides a kind of display unit, and when 1 printing opacity of light valve, ambient light can be irradiated to the first photic deformation
On layer 30, so that the first photic deformation layer 30 can sprawl direction elongation or contraction along it, and with the change of intensity of illumination, first
The deformation extent of photic deformation layer 30 also changes therewith.Because display unit is in display, the light transmission state of light valve 1 can be with aobvious
Show the change of picture and change, thus the first photic deformation layer 30 can extend or shrink, so that the first photic deformation
The free end 301 of layer 30 first electrode 10 and second electrode 20 just to region in move, and then the first photic deformation layer 30
With first electrode 10 and second electrode 20 just to area can change, will so cause the electricity of first electrode 10 and second
The electric capacity that pole 20 is formed changes.Connected in circuit when by first electrode 10 and second electrode 20, first electrode 10 and
The change of the electric capacity that two electrode 20 is formed can in circuit form charging and discharging currents.If by the first electrode 10 in generator unit 2
It is connected with energy-storage units with second electrode 20, just can so reclaims the electric energy of capacitor charge and discharge generation, can also compensate for light
The light transmission state of valve 1 changes the electric energy of consumption, so that display unit more energy-conserving and environment-protective.
Preferably, as shown in Figure 3 and Figure 4, light valve 1 is electrowetting light valve.
Wherein, electrowetting refers to change drop by changing the voltage between drop and insulated substrate on substrate
Wetability, that is, change contact angle, deforms upon drop, the phenomenon of displacement.
