Abstract
The present invention utilizes lenticular grating imaging principle to display stereoscopic image on the liquid crystal display screen. It is mainly characterized by that it utilizes the arrangement mode of liquid crystal display screen whose pixels can be rotated at 90deg. to change the red, green and blue color blocks in original every pixel into transverse arrangement from vertical arrangement, so that it can be matched with lenticular grating to display stereoscopic image.
Description
Technical field the present invention relates to a kind of LCD, especially a kind of stereo-liquid crystal display device.
The maturation of background technology digital technology is the application and the universal life of having brought of stereo-picture.Aspect the 3-D digital display technique, a stereo-liquid crystal display device that Japanese Sharp company goes out can solve the problem of the 3-D digital reconstruction of image effectively, but because the mode that adopts grating to intercept, weaken display brightness and reduced image resolution ratio, be still waiting further improvement.
Summary of the invention is in order to represent three-dimensional image effect better, and the present invention utilizes the column mirror grating principle, column mirror grating is used on the LCDs can the not decay brightness of display of this mode, the obstacle that does not have grizzly bar to block.But because low 3 the primary colours color lumps that mainly are meant the blending color of the resolution of liquid crystal display), every pixel unit is made up of 3 color lumps of red green basket, and these three color lumps are endways being arranged in the pixel, can draw back the distance of these 3 color lumps with column mirror grating with horizontal amplification, make the mixed effect variation (seeing Fig. 2,1) of color.And this mode is very high to the accuracy requirement of grating, if 3 color lumps are not put into raster unit exactly, grating gets more or get less color lump and misalignment of pixels all can make color change.And this mode is also harsh especially to viewing location, almost is again infeasible so column mirror grating is directly used in existing LCD.
Technical scheme of the present invention is: LCD is revolved turn 90 degrees, make the color lump of original endways arrangement become arrangement sidewards, the distance that the only horizontal grating that amplifies does not draw back color lump (is seen Fig. 2,2), and need not all to have got for each random grating and (promptly reduce post mirror radius, increase enlargement factor), the tolerant scope that has increased the grating precision effectively and watched the visual angle.And in this manner, every row pixel of screen can also be divided into two, and the row pixel is expanded be twice, and can intactly show a width of cloth stereo-picture like this, makes the effect of the fine degree of stereo-picture near the common plane demonstration.
The invention has the beneficial effects as follows, by changing the direction that common liquid crystals display picture element color lump is arranged, make the column mirror grating stereo imaging applications on LCD, become possibility, and can make the liquid crystal display displays stereo-picture reach one and be close to perfect degree, for the application of stereo-picture with popularize and created good environment.
Description of drawings Fig. 1 is the column mirror grating principle, among the figure, and the 1, the 2nd, the sight line of right and left eyes, the 3rd, the cross section of grating, 4 is the biserial pixel of left image, 5 is the single column of pixels of right image.In the 3 D grating image that shows, single-row image is taken from the corresponding single-row image of the right anaglyph of stereo-picture, the biserial image is taken from the corresponding biserial image of the left anaglyph of stereo-picture, watch by the column mirror grating on the screen surface, what left eye saw through that grating sees is the left anaglyph of biserial pixel, what right eye saw through that grating sees is the right anaglyph of single column of pixels, the horizontal parallax image reproduces respectively to right and left eyes, by the synthetic lively scene of just experiencing one side emulation of brain, what bring is sensation on the spot in person.
Fig. 2 is the arrangement of pixel color lump on the display.Among the figure, the 1st, the arrangement of common display screen image element; The 2nd, the arrangement of rotation back display screen matrix.Among the figure top little square frame be through raster fashion pixel image.
Fig. 3 is that the arrangement that is divided into two of rotation back display screen arrange pixel and the grating of corresponding grating amplify pixel image.
Fig. 4 is the direction of rotation back display screen scanning.
Embodiment
The simplest mode is joined a slice column mirror grating sheet for display exactly.When watching stereo-picture, display revolved turn 90 degrees, the lenticular lenses subsides are placed on the display screen, the computer video card is set again and elected as the rotation display mode, the 3 D grating image that software is synthetic shows, and adjusts lenticular lenses, itself and liquid crystal display are fitted closely, see earlier whether the lenticular lenses vertical stripes is parallel with the pixel striped on the screen, and not parallel available paper scrap is encased inside lenticular lenses lower end and the place that the screen frame contacts, and makes it parallel.Trickle more horizontal mobile lenticular lenses makes at the centre position viewing effect best.In addition,, also move forward and backward when watching and have a try, find the optimum position, just can appreciate stereo-picture because distance is variant between two of the person to persons.
Next is the modification liquid crystal display, with the distribution of pixel by former display revolve turn 90 degrees mode arrange, arrange pixel in common horizontal screen ratio.The scanning of a display mode is inconvenience substantially, and promptly the direction of scanning is also with 90 degree rotations.Direction of scanning after changing be from top to bottom, (see figure 4) from right to left.During use, the computer setting of video card over there is set at the rotation display mode.The liquid crystal display outside surface is made column mirror grating, and the radius that grating cylinder radius ratio cylinder amplification pixel is a times is smaller; Grating space equals 2 some distances of liquid crystal display, the angle of CONSIDERING EDGE stravismus, and the spacing of grating is smaller approximately.With 15 cun screens is example, its horizontal width is 304.1MM, pixel is 1024, and point is apart from being 304.1 ÷ 1024=0.297, and a grating pair is answered two pixel wide, the angle of CONSIDERING EDGE stravismus, the grating of corresponding edge goes at least 2 pixels (deciding on grating thickness) outside will seeing, promptly the grating of the pixel correspondence at edge should move inward about 1 grating position, also promptly much more on one side gratings, both sides are many two gratings altogether, so grating space is about 304.1 ÷ (1024 ÷ 2+2)=0.59.
In order to pursue more perfect stereo image quality, LCD might be divided into two every row pixel fully, the i.e. pixel that doubles at horizontal direction, as Fig. 3, corresponding grating space is also dwindled one times, can show a complete stereo-picture like this, its image fine degree can be accomplished with the common plane display effect the same.
Because the pixel of display has increased by one times, if video card is not accomplished so high resolution for the moment, the mode that display can be made double screen is connected with computer, be that single column of pixels is a display, the biserial pixel is again a display, two images of two displays are presented on the screen, cooperate with computer with the video card of supporting double screen to show.
Under the double screen mode, display is established the switch on a solid and plane, when not seeing stereo-picture, by the control of this switch will be single-row and biserial in twos and get up, i.e. the original appearance that recovery " is not divided into two " gets final product.
