Cross light adjusting controller smectic liquid crystal dyeing light modulation sheet is controlled, make smectic liquid crystal dyeing light modulation sheet be in frosted state.
Specifically, referring to figs. 2 and 3 understanding, led to the first, second of smectic liquid crystal dyeing light modulation sheet by light adjusting controller
Applying rational low-frequency voltage on electricity electrode layer, making the smectic liquid crystal molecule in smectic liquid crystal mixed layer is that out of order form is arranged
Row, now smectic liquid crystal dyeing light modulation sheet is in frosted state, and the light in actual environment enters smectic liquid crystal dyeing light modulation sheet
After, most light is absorbed, and remaining light passed through scatters, and externally presents black, so that user cannot see the external world clearly
Reality scene, smectic liquid crystal dyeing light modulation sheet effectively completely cut off the void that reality scene self represents with AR/VR display screen 110
Intending scene, it is achieved that VR applies, virtual environment feeling of immersion is strong, and the image sharpness shown is high, and Interactive Experience is effective.
Further, in actual use, controller is driven to be controlled at AR/VR display screen 110 by AR/VR display, and
By micro-projector equipment 150 projection virtual image realize VR or AR application on the basis of, also can be according to actual displayed demand
Smectic liquid crystal dyeing light modulation sheet is made to be in a certain progressive state of translucent gray scale, specifically, by controlling to smectic phase
Voltage swing, frequency or the action time applied on two conductive electrode layers of liquid crystal dyeing light modulation sheet, smectic liquid crystal is made to divide
Son arranges under a certain form between regular and out of order form, i.e. smectic liquid crystal molecular moiety distortion, smectic phase liquid
The progressive state of the translucent gray scale of a certain kind that brilliant dyeing light modulation sheet is between all-transparent state and frosted state, externally presents certain
The black of one degree, mist degree scope is adjustable 1% to 99%, and light penetration is positively retained at more than 80%, thus realizes existing
Light in real environment enters the light direction after smectic liquid crystal dyeing dims sheet, goes out the regulation of light power etc., with by suitably
Regulation realizes the MR effect of desirable degree, and the true effect making dummy object be superimposed upon in actual environment is strengthened, and gives one
Plant true and false inseparable Interactive Experience sense.
After this utility model reaches above-mentioned required each display effect, light adjusting controller just can stop contaminating smectic liquid crystal
The control of tone mating plate, i.e. removes the voltage being applied on smectic liquid crystal dyeing light modulation sheet.After removing voltage, smectic phase liquid
Brilliant dyeing light modulation sheet still can keep the translucent effect produced during on-load voltage, say, that smectic liquid crystal dyeing light modulation
The holding of sheet need not voltage and maintains, this is because smectic liquid crystal dyeing light modulation sheet have " multistable " memory characteristic and
" zero power consumption " characteristic.
The utility model has the advantages that:
This utility model structure and processing technology are simple, simple operation, and user can be adjusted by electrons spread light modulation sheet
Joint controls ambient light transmitance, it is achieved freely switching between VR pattern and AR pattern, and MR effect.
This utility model compensate for tradition VR Yu AR technology defect in the application and restriction so that user can be freely
Regulation and selection display pattern, both can be the immersion VR pattern entirely covered, can switch back into again the AR mould of all-transparent at any time
The MR pattern that formula and realization reality mix mutually with virtual environment, brings complete new experience.
The above is preferred embodiment of the present utility model and the know-why used thereof, for the technology of this area
For personnel, in the case of without departing substantially from spirit and scope of the present utility model, any based on technical solutions of the utility model base
Equivalent transformation on plinth, simple replacement etc. obviously change, within belonging to this utility model protection domain.
