Abstract
The invention discloses a cylindrical lens grating which comprises a plurality of parallel cylindrical lenses. Each cylindrical lens comprises an upper surface and two opposite side faces, wherein the upper surfaces are smooth curved surfaces, and the side faces are accidented curved surfaces. The vertical distance between a vertex on the leftmost side and a vertex on the rightmost side of an irregular curve formed by a projection of any side face out of every two opposite side faces on a pixel is plus-minus 5-20%d, and d is the diameter of each cylindrical lens. Simultaneously, the lenses are arranged on a substrate in parallel in a vertical bar or slanted bar shape. As the side faces of the lenses are in irregular curved surface structures, light passing through the upper surfaces and the side faces are not deflected and do not deform; an image of a black matrix in eyes of a user in the directions is not amplified; only a pattern with the width basically equal to the actual width of the black matrix is formed; and as the actual width of the black matrix is extremely small and the actual effect of the pattern can be ignored, a moire pattern can be suppressed effectively.
Description
Technical field
The present invention relates to a kind of Lenticular screen, grating disparity barrier formula 3 d display device and disparity barrier, be specifically related to a kind of grating of the naked-eye stereoscopic display device without More's interference stripes.
Background technology
Now, 3 d display device more and more is familiar with by popular, and it mainly is to make the observer form stereoscopic vision by certain processing.So-called stereoscopic vision, namely eyes are observed the sensation that things can be differentiated the far and near form of object, by right and left eyes is received respectively different images, perceive stereovision and the depth of field of object after brain is overlapping, thereby experience the stereo perception of object.Therefore, 3 d display device need to separate left eye and independently be received by people's left eye and right eye respectively with the right eye signal, thereby can allow the observer form the stereoeffect of object, finishes stereo display.
At present, the 3 d display device development roughly can be divided into glass-type stereo display device and autostereoscopic display apparatus so far.As its name suggests, thus the observer of glass-type stereo display device need to wear the glasses of response kind of design obtains stereoscopic visual effect; The observer of autostereoscopic display apparatus then need not to wear any additional accessory, can obtain stereoscopic visual effect as normally watching before 3 d display device, since the convenience of bore hole formula observation, at present more and more studied discussion.
The technical method of autostereoscopic display apparatus has multiple, comprises that lens arra, disparity barrier, the degree of depth merge, point to the method such as backlight and right and left eyes information is carried out the space separate.
Lens pillar know-why (bore hole formula 3D), prior art is the column convex lens array that adds periodic arrangement in general display panels outside, as shown in Figure 1, general display panels is by first substrate 1, second substrate 2, and the liquid crystal layer and backlight 5 that is clipped between first substrate 1 and the second substrate 2 forms, simultaneously first basic 1 and second substrate 2 post Polarizer 3, the column convex lens blooming (Lenticular Lens film) that is periodic arrangement adopts outer subsides mode to be attached on the Polarizer 3 of first substrate 1 of panel of LCD.Its design needs to cooperate pixel size and the viewpoint design of display, see through refraction principle, pixel is gone out the light of Come through the lens arrangement of particular design, the generation refraction effect changes, utilize optical imaging concept, on LCD, show different left sides with pixel, right-eye image, allow left eye see the pixel of left-eye images, right eye is seen the pixel of right-eye image, to cause the effect of parallax, so the light through lens will be changed the direction of propagation according to the difference of refractive index, the audience is on a left side, the setting regions that right-eye image pixel light is concentrated reaches the stereoscopic vision impression, thereby can realize that 3D shows.This column convex lens array is parallel and be closely aligned together light is reflected by a plurality of semicylindrical lenses, column convex lens array 70 as shown in Figure 2 is at the perspective view of pixel 100, owing to use lens principle to make deflection of light, the black matrix" that exists between each sub-pixel unit of colored filter can be out of shape under the effect of lens, the black matrix" of these distortion can form moire fringes in the image that the user sees, had a strong impact on the visual effect of image.
Grating disparity barrier formula 3 d display device know-why (bore hole formula 3D) as shown in Figure 3, mainly be to utilize the effect Come of shading to reach the purpose of parallax, utilize one-period crack element, the size of pixel is done design on the fluid,matching LCD panel, utilize light screening material as the barrier of light path in non-crack district, adjust again the display screen of pixel and the distance between crack, the picture of collocation different points of view is done demonstration, allow images of left and right eyes Fen Do see and light to images of left and right eyes then can reach the 3D stereoeffect.
Grating disparity barrier formula 3 d display device technology mainly is divided into 2 kinds, be respectively fixed smooth Gate formula technology and adjustable liquid crystal light Gate technology, wherein fixed smooth Gate formula (Parallax Barrier type) design as shown in Figure 4, be in display panels the place ahead and add that the barrier light Gate that a black and white line is staggered, barrier grating (crack element) are the staggered light Gate of a black and white line.The barrier of barrier grating is the black grating.Because the different result of right and left eyes horizontal level angle allows right and left eyes only can see through the pixel that light Gate sees odd and even number.And adjustable liquid crystal light Gate (LC Barrier type) design as shown in Figure 5, is to increase by a LCD panel above display panels again, and this panel is not had a pixel, only has liquid crystal shutter to show the function of light and shade.Be the panel-switch of the ITO pattern (the pattern ITO of collocation Slit design) of being furnished with slit designs, the ITO electrode strip of this slit designs mainly drives the effect that liquid crystal becomes the required barrier grating of disparity barrier.The barrier of the barrier grating of this moment is that the black grating can be considered the ITO electrode strip.No matter the barrier grating in the grating disparity barrier is the LCD panel-switch that the staggered grating of black and white still is furnished with the ITO pattern of slit designs, and the projection of barrier grating on display panels all is chequered with black and white periodic regular strip light Gate striped as shown in Figure 6.When such optical grating construction cooperates with matrix display when forming auto-stereoscopic display, grating can form fairly obvious optical grating construction square under light illumination, it will and the dot structure of matrix display between produce moire fringes.And along with viewing distance is different with viewing angle, the quantity of moire fringes and shape also change thereupon, and the observation of this moire fringes stereoscopic image can produce interference.
Summary of the invention
