Abstract
The invention discloses a stereoscopic glasses-free polarized display screen, which comprises a display screen body, a polarized film and a lenticular lens grating film, wherein one face of the polarized film is arranged on the surface of the display screen body; and the back surface of the lenticular lens grating film is arranged on the other face of the polarized film. The polarized film and the lenticular lens grating film, which cover a display area, are arranged on the surface of the display screen body, so a consumer can watch lenticular lens grating method video source and can watch a polarization method video source through the stereoscopic glasses-free polarized display screen, and multiple video choice opportunities are obtained.
Description
Technical field
The present invention relates to the display screen field, relate in particular to the display screen that is used for stereo display.
Background technology
Polarization method and lenticular sheet method all are the stereoscopic imaging methods of using always.
What cinema screening adopted is the polarization method.Through two projectors, show two groups of films that two video cameras take synchronously, make this slightly two width of cloth doublings of the image of difference in screen.A polaroid is housed before every projector.Light from two projectors penetrate behind polaroid, has just become polarized light.About the polarization direction of polaroid before two projectors orthogonal, thereby the polarization direction of the two bundle polarized lights that produce is also orthogonal.This two bundles polarized light projects and reflexes to the spectators place in the screen again, and direction of polarized light does not change.After spectators are with polarising glass; Because the polarization axle of two polarized lenses is orthogonal and consistent with the polarization axle of two polaroids before the projection lens about polarising glass; So every eyes are only seen corresponding polarized light image; Be that left eye can only be seen the picture that left machine mirrors, right eye can only be seen the picture that right machine mirrors, and will produce stereo perception like this.
Post lens (Lenticular Lenses) raster method is without wearing spectacles, and bore hole just can be watched stereoscopic picture plane.Post lens type 3D stereo display screen is provided with the cylinder lenses film in screen surface, and scioptics reflect controls light going direction, lets about spectators two to accept different images and produce parallax, thereby presents stereoeffect.Adopt the post lenticulation to realize the historical remote of three-dimensional imaging, range of application is also quite extensive, comprises that planographic, screen display can both use this mode to present the 3D stereoscopic picture plane, and common on the market three-dimensional backing plate utilizes this principle made exactly.Except presenting stereopsis, the post lenticulation can also be used for appearing with the different images that change of spectators' viewing angle.
Present 3D rendering display screen all designs to single stereoscopic imaging method, if consumer's use is the 3D display screen that is applicable to the polarization method, then can't watch post lenticulation method film source; Otherwise, if consumer's use is the 3D display screen that is applicable to post lenticulation method, then can't watch polarization method film source, this has brought inconvenience to the consumer.
Summary of the invention
Technical matters to be solved by this invention is to provide a kind of can watch post lenticulation method film source, can watch the display screen of polarization method film source again.
The technical scheme that the present invention adopted is: the naked polarisation display screen of looking of a kind of solid comprises display screen, polarizing coating and post lenticulation film; The one side of polarizing coating is arranged on the surface of said display screen, and the back side of post lenticulation film is arranged on the another side of polarizing coating.
Display screen surface of the present invention is provided with polarizing coating and the post lenticulation film that covers on the viewing area simultaneously; Make the consumer when adopting display screen of the present invention, can watch post lenticulation method film source, can watch polarization method film source again, thereby obtain more film choice.In addition, the present invention is simple in structure, is convenient to implement.
Description of drawings
Fig. 1 is the three-dimensional naked structural representation of looking the polarisation display screen according to one embodiment of the present invention.
Fig. 2 and 3 looks the effect synoptic diagram that the polarisation display screen is used to show polarization method film source according to one embodiment of the present invention three-dimensional naked.
Fig. 4 looks the effect synoptic diagram that the polarisation display screen is used for display column's lenticulation method film source according to one embodiment of the present invention three-dimensional naked.
Embodiment
Below in conjunction with accompanying drawing the present invention is made and to further specify.
As shown in Figure 1, the naked polarisation display screen of looking of solid of the present invention comprises display screen 1, polarizing coating 2 and post lenticulation film 3.Wherein, display screen 1 is the display screen of common demonstration two dimensional image, like LCD display, PDP display or the like.In order to reduce because the output image brightness that pad pasting caused descends to the influence of view reception effect as far as possible, display screen 1 preferably adopts the display screen of high brightness, for example LED display.
The one side of polarizing coating 2 is close on the surface of display screen 1, covers the whole viewing area of display screen 1, and the back side of post lenticulation film 3 is close on the another side of polarizing coating 2.Preferably, the size of post lenticulation film 3 is more than or equal to polarizing coating 2, to cover whole polarizing coating 2 fully.In one embodiment, display screen 1, polarizing coating 2 and post lenticulation film 3 be shaped as rectangle, the length and the width of polarizing coating 2 and post lenticulation film 3 all equate.
In embodiment shown in Figure 1; Polarizing coating 2 is made up of a plurality of polarizing coatings unit 21; This a plurality of polarizing coatings unit 21 is arranged on the top of the multiple row pixel column 11 of display screen 1 correspondingly, and the width of polarizing coating unit 21 equals the width w1 of the pixel column 11 of display screen 1.Polarization direction L, the R of adjacent per two polarizing coating unit 21 are vertical each other.For example, in adjacent per two polarizing coating unit, if the polarization direction L of a polarizing coating unit 21 is a horizontal direction, then the polarization direction R of another polarizing coating unit 21 is a vertical direction.Post lenticulation film 3 is made up of a plurality of post lens units 31, and the width w2 of each post lens unit equals the width sum of four row pixel columns, i.e. 4 * w1.
The display mode of display screen when showing polarization method film source according to one embodiment of the present invention is following: left-eye image and eye image with parallax are play on same display screen simultaneously, and be as shown in Figure 2.The light of above-mentioned left-eye image and eye image as long as spectators wear the polarising glass as analyzer, just can make people's right and left eyes observe the image that two width of cloth have parallax respectively through behind the polarizing coating as the polarizer, and is as shown in Figure 3.
As shown in Figure 4; Following according to the display screen of one embodiment of the present invention display mode when display column's lenticulation method film source: several pixel columns are common to constitute a width of cloth left-eye image; The in addition several pixel columns adjacent with above-mentioned several pixel columns constitute eye image jointly, and are so staggered.When display screen was play the stereo-picture of post lenticulation method film source, post lenticulation film 3 can reflect the light of display screen output, makes user's bore hole just can see stereo-picture.
