Description

A kind of device of longitudinal direction/horizontal turnover liquid crystal light grid screen
Technical field
The utility model is related to technical field of flat panel display, more particularly to the screen of the carried out Three-dimensional Display based on electric light grid Proscenia.
Background technology
With the development of science and technology, people are to the requirement also more and more higher that shows.Final being contemplated to be of people can simulate existing It is real, realize Three-dimensional Display.Through years of researches, dimension display technologies have had certain development.Two kinds of current main flow Dimension display technologies are spectacle dimension display technologies and bore hole formula dimension display technologies.
The principle of spectacle Three-dimensional Display is to produce three-dimensional effect using what the subtense angle and convergence function of people's eyes made The film of fruit.Three-dimensional film is exactly, with two camera lens filming apparatus as human eye, to shoot the double vision dot image of lower scenery.Again By two projectors, the image synchronization projection of two viewpoints, this slightly differentiated two width image is set to be displayed in screen, this Shi Ruguo eyes direct viewings, it is seen that picture be overlap, some are smudgy, to see stereopsis it is necessary to take Measure, makes left eye only see left image, and right eye only sees right image, and contrary inclined of a Block direction is such as filled before every frame projector Shake piece, and it functions as the polarizer, the light projected from projector after polarizer, just into polarised light, left and right two frame The polarization direction of the polarizer before projector is orthogonal, thus the polarization direction of the two beam polarised lights for producing is also orthogonal, This two beams polarised light projected and be re-reflected in screen at spectators, and direction of polarized light does not change, and spectators are above-mentioned inclined using correspondence Shake light polarising glass viewing, i.e., left eye can only see the picture that left machine is mirrored, and right eye can only see the picture that right machine is mirrored, this Sample just can be appreciated that three-dimensional scene, here it is the principle of three-dimensional film.
Middle employing colorized glasses method at the cinema.Colorized glasses method is two images two viewing angles in left and right, point Do not overlapped with red and blue or green (or green) color and printed on same picture, make a cinefilm.General projection is can use to set during projection It is standby, but spectators need to wear it is a piece of for the red another glasses for blue or green (or green) color.Make to can only see redness by the eyes of red eyeglass Image, by the eyes of cyan eyeglass cyan colored images are can only see.The shortcoming of this method is that the wink of spectators two feels uneven, easily tired Labor.
Due to spectacle/helmet-type dimension display technologies cause beholder have to wear extra device such as glasses or The helmet, it is certain restricted that this causes its application to receive.And, this Three-dimensional Display can cause film flicker, brightness big The problems such as heavy discount, easily cause eye fatigue.
Then people start to develop emphatically need not wear glasses/the naked eye three-dimensional Display Technique of the helmet, this technology is main Based on existing flat panel display systems, by binocular parallax and motion parallax with reference to level, and in existing FPD Additional some optic modulating devices in system, people can be allowed not wear glasses can the impression of stereoscopic vision.
At present the bore hole 3D technology of main flow has:Bore hole 3D technology means have:Slit liquid crystal grating, column prism, sensing Light source.1st, slit liquid crystal grating.This know-why is to have added before screen after a slit grating, it should by left eye When the image seen is displayed on liquid crystal display, opaque striped can block right eye;In the same manner, it should which the image seen by right eye shows When showing on liquid crystal display, opaque striped can block left eye, by the way that the viewable pictures of left eye and right eye are separated, see onlooker To 3D images.2nd, this know-why of column prism is the refraction principle by lens, by the corresponding pixel difference of right and left eyes In being incident upon right and left eyes, realize that image is separated.3rd, light source is pointed to, is exactly in brief that the stack screen of precise control two is distinguished to the left and right Eye projects images.
But the needs that at present the existing two dimension of display device shows, also have the needs that bore hole 3D shows, how using one kind Structure is easily switched between two dimension shows and bore hole 3D shows.And, on the mobile apparatus would generally transverse screen show Or portrait layout shows, and optical barrier type 3D technology is typically only capable to ensure the bore hole 3D display effect on a direction, does not do Method can guarantee that it has bore hole 3D display effect when transverse screen shows or has bore hole 3D display effect when portrait layout shows.
