Embodiment three
The present embodiment, based on above-described embodiment, the basis of above-described embodiment is optimized, and is specially the principle of work providing three kinds of liquid crystal, is optimized the lcd window provided in above-described embodiment.
Further, liquid crystal layer can be polymer dispersed liquid crystal layer, polymer stabilizing bistable cholesteric liquid crystal layer or double frequency cholesteric crystal layer.
The optics had due to liquid crystal molecule and dielectric anisotropy, in the electric field, if electric field intensity is greater than liquid crystal drive threshold value, will arrange along direction of an electric field for major axis positivity liquid crystal molecule; Will arrange along direction of an electric field for minor axis negative liquid crystal molecule.Fig. 6 is the principle of work of Polymer Dispersed Liquid Crystal in the control method of a kind of lcd window that the utility model embodiment three provides, as shown in Figure 6, at Polymer Dispersed Liquid Crystal (PoiymerDispersedLiquidCrystal, PDLC) in, during no power, liquid crystal molecule optical axis direction points to from all directions, and liquid crystal device presents high scattering state (opaque); During energising, liquid crystal molecule is stood up, and optical axis direction is consistent, and liquid crystal presents pellucidity, as shown in Figure 6.Electrode is had to form with electrodeless place the generation that different states realizes pattern.
Concrete, the driving voltage of Polymer Dispersed Liquid Crystal is about 20V, and when driving voltage reaches 20V, Polymer Dispersed Liquid Crystal is started working, and uses the lcd window of this liquid crystal just can present the pattern corresponding with pattern electrode layer.Optionally, can be strip electrode pattern, also can be ring electrode pattern, can also be rectangular electrode pattern, can not also display electrode pattern, and namely whole lcd window presents all-transparent or full opaque state.
Fig. 7 is the principle of work of polymer stabilizing bistable state cholesteric liquid crystal in the control method of a kind of lcd window that the utility model embodiment three provides, as shown in Figure 7, when polymer stabilizing bistable state cholesteric liquid crystal is as material, plane state texture is formed in the parallel box after orientation, due to the refractive anisotrop of liquid crystal molecule, in the process that liquid crystal molecule rotates, define self assembly refraction mechanical periodicity, liquid crystal molecule rotating 360 degrees is one-period, and its length is called pitch.For a certain liquid crystal, the difference of pitch, the optical wavelength of reflection is different, and determined by Bragg reflection formula: λ=np, λ represents reflection wavelength here, and n represents effective refractive index, and p represents pitch.Use this type of liquid crystal can make color liquid crystal window and also can do colourless lcd window.For bistable liquid crystal, when higher voltage puts on liquid crystal, cholesteric liquid crystal molecule all vertically can arrange formation " H " state, now liquid crystal layer is pellucidity, when voltage reduces rapidly, cholesteric liquid crystal molecule forms plane state in liquid crystal cell, can realize long-term clear state under this state without the need to lasting making alive; When voltage slowly reduces, liquid crystal molecule can change Focal conic state into from " H " state, and under this state, liquid crystal molecule optical axis direction is disorderly and unsystematic, realizes high scattering state, now also also can keep opaque state without the need to being continuously applied voltage.This two states (plane state and Focal conic state) all maintains without the need to extra electric field can be steady in a long-term, so be called bistable state, as shown in Figure 7.
Concrete, the driving voltage of polymer stabilizing bistable state cholesteric liquid crystal is about 100V, when driving voltage reaches 100V, cholesteric liquid crystal molecule all vertically can arrange formation " H " state, now liquid crystal layer is pellucidity, when voltage reduces rapidly, cholesteric liquid crystal molecule forms plane state in liquid crystal layer, long-term clear state can be realized without the need to lasting making alive under this state, when voltage slowly reduces, liquid crystal molecule can change Focal conic state into from " H " state, under this state, liquid crystal molecule optical axis direction is disorderly and unsystematic, realize high scattering state, now also also opaque state can be kept without the need to being continuously applied voltage.Utilize this principle the utility model to use polymer stabilizing bistable state cholesteric liquid crystal can prepare the electrode of multiple patterns, single liquid crystal layer just can realize the formation of the many patterns of liquid crystal window.
Fig. 8 is the principle of work of double frequency cholesteric liquid crystal in the control method of a kind of lcd window that the utility model embodiment three provides, as described in Figure 8, double frequency cholesteric liquid crystal realizes changing between plane state and Focal conic state, its Liquid Crystal Molecules Alignment structure is the same with the arrangement architecture of polymer stabilizing bistable state cholesteric liquid crystal, just this type of liquid crystal is when HF voltage and low-frequency voltage, and its specific inductive capacity has a conversion.When an applying low-frequency voltage, cholesteric liquid crystal is converted into Focal conic state from plane state, and liquid crystal presents opaque state; When applying HF voltage, cholesteric liquid crystal molecule will get back to plane state, and now liquid crystal presents pellucidity, as shown in Figure 8.
Concrete, the driving voltage of double frequency cholesteric liquid crystal is at below 20V, and when an applying low-frequency voltage, cholesteric liquid crystal is converted into Focal conic state from plane state, and liquid crystal presents opaque state; When applying HF voltage, cholesteric liquid crystal molecule will get back to plane state, and now liquid crystal presents pellucidity, utilizes this principle to modulate lcd window, realizes the liquid crystal window of many patterns.
The control method of the lcd window that the utility model embodiment three provides, by the principle of work of three kinds of different liquid crystal, provides the control method of three kinds of lcd windows, controls the function that lcd window realizes possessing many patterns.
Note, above are only preferred embodiment of the present utility model and institute's application technology principle.Skilled person in the art will appreciate that the utility model is not limited to specific embodiment described here, various obvious change can be carried out for a person skilled in the art, readjust and substitute and protection domain of the present utility model can not be departed from.Therefore, although be described in further detail the utility model by above embodiment, but the utility model is not limited only to above embodiment, when not departing from the utility model design, can also comprise other Equivalent embodiments more, and scope of the present utility model is determined by appended right.
