Description
Technical field
The present invention relates to dimension display technologies field, persist bore hole 3D of effect more particularly, to a kind of view-based access control model
Holographic double-side display device.
Background technology
Compare flat LED Display Technique, three-dimensional (3D) stereoscopic image display have contain much information, can be by actual scene
The feature that three-dimensional information all reproduces out, make beholder directly can find out from display the distance of each object in image,
Depth, therefore beholder can obtain information more comprehensively and intuitively.People generally can be by means of the mode of 3D glasses in the past
Realize the observation of three-dimensional information.This mode is mainly by principle of parallax, when beholder watches picture, as long as providing shooting
The two groups of images somewhat staggered in position, watch for right and left eyes respectively, cause the difference of the depth of field, just it can be seen that one group has solid
The picture of sense.The conventional method realizing principle of parallax mainly has color separation, light splitting, timesharing and grating etc..The solid of wears glasses
Display Technique, although having good stereo display effect, but in many occasions inapplicable.
Along with the development of 3D technology, naked eye three-dimensional LED technology is in virtual reality technology, 3D game, 3D advertisement, aviation boat
My god, the field such as nuclear technology, biomolecule has wide practical use.But, in terms of light-emitting diode display, current domestic existing
Light-emitting diode display is still based primarily upon planar LED display, wherein colorful lamp bead (i.e. tri-LED of RGB) is concentrated on a closing
Device in and this device press matrix form arrangement, by line by line or interleaved form display picture.Current is naked
The raster pattern 3D auto-stereoscopic display that eye 3D auto-stereoscopic display is mainly based upon binocular parallax and develops.
In prior art, the Chinese invention patent application of Application No. CN201510627595 discloses a kind of omnidirectional bore hole
3D display device, the motor rotated including rotating shaft and drive shaft, rotating shaft sidewall is provided with a plurality of equally distributed pixel and sends out
Luminous point, and it is in the multiple around between described pixel light emission point and the spindle central of the setting of rotating shaft sidewall of sustained height
Distance differs.The Chinese utility model patent of Application No. CN201620046587 discloses a kind of bore hole 3D display device, bag
Including LED display board, hurricane globe, base, rotating disk, conducting slip ring, hollow shaft motor, described conducting slip ring is arranged on hollow axle electricity
On machine, conducting slip ring and hollow shaft motor are positioned at base；Described rotating disk is arranged on conducting slip ring, and rotating disk is positioned on base
Side；Described hurricane globe is arranged on the upside of rotating disk；Described LED display board be enclosed within cylinder hurricane globe in, and be fixed on turn
On dish.Application No. CN201120442036 discloses a kind of similar naked eye three-dimensional display device.
But, the display device of above-mentioned bore hole 3D Display Technique manufacture relies on when all disadvantage is that due to display
Be constitute panel type display device, along with display area expansion, the display device quantity that display includes will gradually increase
Many, cost will be more and more higher, seriously constrain the current expectation generally wishing to view and admire large screen display.It addition, along with display
The increase of panel area, its weight, the aspect such as quantity of device will bring the inconvenience of installation difficulty, difficult, especially when
When it rotates, rotating of the panel of large volume will easily make panel itself significantly increase along the centrifugal action rotating radial direction
By force so that the internal stress of display floater changes, not only speeded up the aging of panel, and easily caused the inside of panel
Liquid crystal structure or the damage of circuit.During additionally, panel rotational time is long, windage noise, wind-force and the heat that panel produces will
Rotary course constantly diffuses out, affects 3D display picture and view and admire experience.
Summary of the invention
For the drawback overcoming existing bore hole 3D display floater to exist, the invention provides a kind of view-based access control model and persist effect
The bore hole 3D holography double-side display device answered.
The present invention is the principle utilizing " the point is moved into a line, line moves into face ", by colorful LED lamp pearl, i.e. concentrates the RGB of an encapsulation
LED lamp bead arranges in the form of a line, i.e. " lamp bar ".Whole system can be made up of four lamp bars, allows lamp bar with certain speed rotation
Turn；I.e. form the cylinder monitor of a display.By perspective background, it is achieved 3D.
After lamp bar is by certain orbiting motion, can form a track plane, each RGB lamp bead can form trajectory,
Lamp bar rotation cycle turnover interior (this cycle is less than picture in human eye residence time), each RGB lamp bead is in its trajectory
A corresponding moment will be had corresponding, then the picture one_to_one corresponding that the track plane that lamp bar is formed shows with needs, according to picture
The pixel (RGB lamp bead) corresponding to track plane that the lamp bar of motion is formed is lighted, it is possible to display picture needed for face, due to
Being to be rotated by lamp bar, the screen theme of display out, is floated by the track plane " thoroughly " that the background of reality can be moved by lamp bar
Show among the environment of reality, and reach the display effect of a kind of 3D.
According to an aspect of the present invention, the view-based access control model of the present invention persists the bore hole 3D holography double-side display device bag of effect
