Description
Technical field
The utility model is related to the bore hole 3D display device in LED screen, LCD screen or rear projection screen for the beautiful polka-dot raster, is
A kind of using beautiful polka-dot raster can make LED screen, LCD screen or the image shown by rear projection screen shown by plane be changed into naked
Eye 3D shows, reaches the new technology of stereoscopic three-dimensional visual effect.
Background technology
Advance by leaps and bounds and human society sustainable development with science and technology, LED display curtain has environmental protection, high brightness, height
The advantages of characteristics such as definition, high reliability, also have and can arbitrarily extend, and achievable seamless spliced, widely applies
In the indoor and outdoor advertising of the various public place such as airport, market, exhibitions and office building, or even initially enter common people family.
LED screen development prospect is extremely wide, just develops towards the uniformity of less spacing and Geng Gao and reliability direction.
LCD Panel existing nearly 50 years history since nineteen sixty-eight RCA Corp. of U.S. research and development release, has environmental protection
The characteristics such as power saving, high brightness, fine definition, high reliability, also have the advantages that dynamic contrast and natural light regulation technology, and
To lightly ultra-thin super large and intelligent development, have been widely used for airport, station, market, bank and office building etc. various
The advertising of public place, liquid crystal TV set even more becomes the indispensable necessity of common people masses family.
Optical glass projection display screen has the characteristics such as environmental protection, power saving, fine definition, high reliability, also has color
Bright-coloured soft, visible angle is wide and the advantages of 100 140 inches of large scales, as new master's product can apply to airport, market,
The house ads publicity of the various public place such as exhibitions and office building.Family's Projection Display increased popularity, projection display screen will
The common people family of upper income level in being entered with private savings movie theatre form.Projection screen development prospect is very good, just towards bigger
The direction of size and more high brightness is developed.
But bore hole 3D shows the short slab and weakness remaining LED screen, LCD screen and projection screen, at present commercially
Also appear on the market less than the high LED screen with bore hole 3D good visual effect of cost performance and projection screen.
Prism (mirror) grating technology of many utility model creators and producer's research and development test manufacture is mainly used in bore hole before this
3D LCD Panel, all has the moire fringes (being commonly called as water ripples) being difficult to avoid that, leads to image distortion deformation variable color, exists
Make us the major defects such as dizzy and visual fatigue it is impossible to allow consumer satisfaction, therefore, it is difficult to commercialization is promoted.Reason is, liquid
Crystal display screen technology is shown from left to right or from right to left using matrix liquid crystal molecule grid arrangement, when prism (mirror) grating pendulum
Synthesis light before being placed on LCD screen, after two screens superpositions, after the close constant amplitude sinusoid light superposition of two bar column frequencies
Amplitude will change according to the difference of two frequencies, and creating water ripples colored and in irregular shape is moire fringes, interference and
Destroy shown image, it is to cause the adverse consequences such as dizzy and visual fatigue.Therefore, prism grating technology can not be applied
In LCD screen.Equally, theory and practice proves：Either single or multiple lift prism (mirror) grating screen or helical form cincture
Grating screen, or there is certain gradient prism (mirror) grating screen, apply and there is in LCD Panel bore hole 3D effect
Moire fringes phenomenon inevitably occurs simultaneously and all it is impossible to satisfactory and pleasure comfortable.
Utility model content
The short slab existing in bore hole 3D Display Technique for existing LED screen, LCD screen or rear projection screen and weakness,
The utility model provides a kind of beautiful polka-dot raster in the bore hole 3D display device of LED screen, LCD screen or rear projection screen.
For achieving the above object, the utility model creation technical scheme is：
