Description
One, technical field
The present invention relates to the stereo display technique field, more precisely relate to the cylindrical grating stereo display technique.
Two, background technology
The cylindrical grating three-dimensional display is simple in structure, and does not need the beholder to wear anaglyph spectacles.Install the cylindrical grating of certain parameter in the image display panel front additional, just constitute the cylindrical grating three-dimensional display.Viewpoint is a location point in cylindrical grating three-dimensional display the place ahead, and eyes can be seen a complete anaglyph at that point.Corresponding independently anaglyph of a width of cloth that shows of viewpoint in the cylindrical grating three-dimensional display, the viewpoint number is the quantity that the cylindrical grating three-dimensional display can show different anaglyphs.Utilize cylindrical lens raster to interception of rays, and, just can on the viewpoint of diverse location, watch different anaglyphs the different anaglyph of the staggered demonstration of each sub-pixel on the image display panel.The spacing of adjacent viewpoint just in time equals ordinary people's binocular interval, divides although different anaglyph the time, just can produce the sensation of solid when beholder's eyes.
Cylindrical grating is made up of a plurality of cylindrical lenses, cylindrical lens structure and operation principle as shown in Figure 1, beholder's eyes are when different directions is watched, the light that eyes received derives from a fine rule on the cylindrical lens focal plane, is focal line.The focal line that different view directions is corresponding different.When picture point just in time was positioned on the focal line of eye position correspondence, this picture point just can be in sight, otherwise just can not be in sight.The image that utilizes this principle just beholder's eyes can be seen separates.
Existing cylindrical grating three-dimensional display, the beholder only can see on limited several viewpoints does not have the stereo-picture of crosstalking.Because the beholder by cylindrical grating picture display screen with the aid of pictures the time, be a focal line seeing each cylindrical lens correspondence in fact image display panel the light-emitting zone of process.When beholder's eyes position is not when being positioned on the viewpoint just, the focal line of this position correspondence must be through showing the sub-pixel of different points of view anaglyph.That is to say that when beholder's eyes position is not just on viewpoint the time, the image of seeing must be crosstalked.Usually the shape of the arrangement mode of change image display panel sub-pixel or change sub-pixel waits to eliminate and crosstalks.
Three, summary of the invention
The present invention proposes a kind of method that adopts colour filter to reduce cylindrical grating three-dimensional display picture crosstalk, cylindrical grating, colour filter and image display panel are placed successively, wherein, on the focal plane of cylindrical grating, place colour filter and filter, thereby reduce picture crosstalk between viewpoint causing the light of crosstalking between viewpoint.
Preferably, the described cylindrical grating cycle is D, and its angle with arctan (1/3) is formed the cylindrical grating three-dimensional display with n viewpoint with the described image display panel with vertical colour bar sub-pixel structure, and wherein n is the natural number more than or equal to 2;

Five, embodiment
Describe in detail below and utilize an a kind of exemplary embodiments that adopts the method that colour filter reduces cylindrical grating three-dimensional display picture crosstalk of the present invention, the present invention is further described.Be necessary to be pointed out that at this; following examples only are used for the present invention and are described further; can not be interpreted as limiting the scope of the invention; this art skilled person makes some nonessential improvement and adjustment according to the foregoing invention content to the present invention, still belongs to protection scope of the present invention.
Image display panel adopts the arrangement of subpixels mode of vertical colour bar structure, each sub-pixel is 1: 3 a rectangle, realizing together in the process of stereo display with cylindrical grating, appearance for fear of colored Morie fringe, cylindrical grating will be with angle and the display combination of arctan (1/3), each sub-pixel is used to show different anaglyphs simultaneously, and the arrangement of subpixels direction of same anaglyph correspondence is also consistent with the cylindrical grating direction.As shown in Figure 2, it is red, green and blue that the color of the letter r among the figure, G and B presentation video display screen sub-pixel is respectively, and label represents which width of cloth anaglyph this sub-pixel is used to show.For this cylindrical grating three-dimensional display, the beholder only can see on limited several viewpoints does not have the stereo-picture of crosstalking.Because the beholder by cylindrical grating picture display screen with the aid of pictures the time, be a focal line seeing each cylindrical lens correspondence in fact image display panel the light-emitting zone of process.When beholder's eyes position is not when being positioned on the viewpoint just, the focal line of this position correspondence must be through showing the sub-pixel of different points of view anaglyph, as shown in Figure 3.That is to say that when beholder's eyes position is not just on viewpoint the time, the image of seeing exists crosstalks.
The concrete structure of colour filter depends on the viewpoint number of angle of inclination, grating cycle and the stereo display of grating.When the stereo display with n viewpoint, and grating and image display panel be when installing with arctan (1/3) angle, and the grating cycle equals D, and the colour filter structure as shown in Figure 4.This colour filter is positioned on the focal plane of cylindrical grating, the array of being made up of color-filter unit constitutes, the column direction of color-filter unit array is consistent with the cylindrical grating direction, and the letter r among the figure, G and B represent that color-filter unit allows the color of transmitted light to be respectively red, green and blue.The width of color-filter unit is D/n, highly is
And D * cos[arctan (1/3) one by one descends in each unit on the line direction of color-filter unit array]/height of n.The light color that each color-filter unit on the color-filter unit array line direction allows to see through is followed successively by redness, green and blue, goes round and begins again; On the vertical direction, the color-filter unit that allows to see through different colours light staggers mutually, and is periodically repeated arrangement.Under the effect of colour filter, the sub-pixel of image display panel different colours will be fallen a part of light by retaining respectively, and at the place, focal plane of cylindrical grating, the light transmission part just becomes pattern as shown in Figure 5 like this.
Like this, the light that all only remaining sub-pixel that shows an anaglyph sends on any focal line, as shown in Figure 6.When beholder's eyes are not when just in time being on the viewpoint, the light that enters eyes remains and all comes from a certain width of cloth anaglyph, because the light on the corresponding focal line comes from the sub-pixel that shows same width of cloth anaglyph entirely, the image of seeing like this nature is without any crosstalking.
Preferably there is a small amount of lighttight part in the edge of each color-filter unit of colour filter, so that with each cellular zone separately, and further reduces picture crosstalk between viewpoint.
The cylindrical grating arctan1/3 angle that tilts counterclockwise is installed on the LCD and constitutes one 42 cun cylindrical grating three-dimensional display, LCD shows that resolution is 1920 * 1080, sub-pixel is 0.1614mm * 0.4843mm, the sub-pixel of same color vertically is arranged in straight line, and the cylindrical grating cycle is 1.3783mm.On the focal plane of cylindrical grating, settle colour filter, the color-filter unit of colour filter is 0.1531mm * 0.5105mm, the color-filter unit array follows direction decline 0.0538mm, red, green and blue color-filter unit evenly alternately appear in each row of color-filter unit array, the color-filter unit color staggers one between next line and the lastrow, as shown in Figure 7.Picture crosstalk has just been eliminated between this important actor concave grating three-dimensional display viewpoint.
