The optics and dielectric anisotropy having due to liquid crystal molecule, in the electric field, if electric field strength is more than liquid crystal drive
Threshold value, long axis will be arranged along direction of an electric field for positive liquid crystal molecules;Short axle will for negative liquid crystal molecule
It can be arranged along direction of an electric field.Fig. 6 be the embodiment of the present invention three provide a kind of LCD window control method in polymer disperse
The operation principle of liquid crystal, as shown in fig. 6, polymer dispersed liquid crystals (Poiymer Dispersed Liquid Crystal,
PDLC in), when no power, liquid crystal molecule optical axis direction is directed toward from all directions, and it is (impermeable that liquid crystal device shows high scattering state
It is bright);When energization, liquid crystal molecule is stood up, and optical axis direction is consistent, and liquid crystal shows pellucidity, as shown in Figure 6.There is electrode
The state different with electrodeless local formation, realizes the generation of pattern.
Specifically, the driving voltage of polymer dispersed liquid crystals is about 20V, and when driving voltage reaches 20V, polymer dispersion
Liquid crystal is started to work, and will show pattern corresponding with pattern electrode layer using the LCD window of the liquid crystal.Optionally, Ke Yishi
Strip electrode pattern can also be annular electrode pattern, can also be rectangular electrode pattern, can not also display electrode pattern,
All-transparent or full opaque state is presented in i.e. entire LCD window.
Fig. 7 be the embodiment of the present invention three provide a kind of LCD window control method in polymer stabilizing bistable state cholesteric phase
The operation principle of liquid crystal, as shown in fig. 7, when polymer stabilizing bistable state cholesteric liquid crystal is as material, after orientation
Plane state texture, due to the refractive anisotrop of liquid crystal molecule, shape during liquid crystal molecule rotates are formed in parallel box
Mechanical periodicity is reflected at self assembly, liquid crystal molecule is rotated by 360 ° as a cycle, and length is known as screw pitch.For a certain kind
For liquid crystal, the optical wavelength of the difference of screw pitch, reflection is different, is determined by Bragg reflection formula:λ=np, λ, which is represented, here reflects
Wavelength, n represent effective refractive index, and p represents screw pitch.Can make color liquid crystal window using such liquid crystal can also do no dichroic liquid crystal
Window.For bistable liquid crystal, when higher voltage is applied to liquid crystal, cholesteric liquid crystal molecule all can be vertically arranged to be formed
" H " state, liquid crystal layer is pellucidity at this time, and when voltage reduces rapidly, cholesteric liquid crystal molecule forms plane state in liquid crystal cell,
It is not necessarily to lasting making alive under this state, long-term transparent state can be realized;When voltage slowly reduces, liquid crystal molecule can change from " H " state
For Focal conic state, liquid crystal molecule optical axis direction is disorderly and unsystematic under this state, realizes high scattering state, at this time without being continuously applied electricity
Pressure can also keep opaque state.Both states (plane state and Focal conic state) are all not necessarily to extra electric field maintenance can be steady for a long time
It is fixed, so referred to as bistable state, as shown in Figure 7.
Specifically, the driving voltage of polymer stabilizing bistable state cholesteric liquid crystal is about 100V, when driving voltage reaches
When 100V, cholesteric liquid crystal molecule can all be vertically arranged to form " H " state, and liquid crystal layer is pellucidity at this time, when voltage drops rapidly
Low, cholesteric liquid crystal molecule forms plane state in the liquid crystal layer, can be realized under this state without lasting making alive long-term transparent
State, when voltage slowly reduces, liquid crystal molecule can be changed into Focal conic state from " H " state, and liquid crystal molecule optical axis direction is mixed and disorderly under this state
Without chapter, high scattering state is realized, can also keep opaque state without being continuously applied voltage at this time.Utilize this hair of this principle
The bright electrode that multiple patterns can be prepared using polymer stabilizing bistable state cholesteric liquid crystal, single liquid crystal layer can realize liquid
The formation of the brilliant more patterns of window.
Fig. 8 be a kind of LCD window that the embodiment of the present invention three provides control method in double frequency cholesteric liquid crystal work it is former
Reason, as described in Figure 8, double frequency cholesteric liquid crystal is realized to be changed between plane state and Focal conic state, Liquid Crystal Molecules Alignment structure with it is poly-
Close object stablize bistable state cholesteric liquid crystal arrangement architecture it is the same, only such liquid crystal is in high frequency voltage and when low-frequency voltage,
Dielectric constant can there are one conversions.When applying a low-frequency voltage, cholesteric liquid crystal is converted into Focal conic state, liquid crystal from plane state
Opaque state is presented;When applying high frequency voltage, cholesteric liquid crystal molecule will return to plane state, and liquid crystal is presented transparent at this time
State, as shown in Figure 8.
Specifically, the driving voltage of double frequency cholesteric liquid crystal in 20V hereinafter, when applying a low-frequency voltage, cholesteric phase
Liquid crystal is converted into Focal conic state from plane state, and opaque state is presented in liquid crystal;When applying high frequency voltage, cholesteric liquid crystal molecule will
Plane state can be returned to, pellucidity is presented in liquid crystal at this time, is modulated to LCD window using this principle, realizes the liquid crystal of more patterns
Window.
The control method for the LCD window that the embodiment of the present invention three provides is provided by the operation principle of three kinds of different liquid crystal
The control method of three kinds of LCD windows, control LCD window realize the function of having more patterns.
Note that above are only presently preferred embodiments of the present invention and institute's application technology principle.It will be appreciated by those skilled in the art that
The present invention is not limited to specific embodiments described here, can carry out for a person skilled in the art it is various it is apparent variation,
It readjusts and substitutes without departing from protection scope of the present invention.Therefore, although being carried out to the present invention by above example
It is described in further detail, but the present invention is not limited only to above example, without departing from the inventive concept, also
May include other more equivalent embodiments, and the scope of the present invention is determined by scope of the appended claims.
