Description

3 d display device

Technical field

The utility model relates to a kind of 3 d display device, particularly a kind of lens pillar array mode (Lenticular Lens type) 3 d display device.

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 through certain processing.So-called stereoscopic vision, promptly eyes are observed the sensation that things can be differentiated the far and near form of object, through right and left eyes is received different images respectively, after brain is overlapping, perceive the stereovision and the depth of field of object, thereby experience the stereo perception of object.Therefore, 3 d display device need separate left eye and independently received by people's left eye and right eye respectively with the right eye signal, thereby can let the observer form the stereoeffect of object, accomplishes stereo display.

At present, the 3 d display device development roughly can be divided into eyeglass stereoscopic display device and autostereoscopic display apparatus so far.As its name suggests, thus the observer of eyeglass stereoscopic display device need wear the glasses of Response Design type obtains stereoscopic visual effect; The observer of autostereoscopic display apparatus then need not to wear any additional accessory, as normal viewing, before 3 d display device, can obtain stereoscopic visual effect, because the convenience of bore hole formula observation is being studied discussion at present more and more.

The technical method of autostereoscopic display apparatus has multiple, comprises that lens arra, disparity barrier, the degree of depth merge, point to method such as backlight right and left eyes information is carried out apart.Lens arra formula 3 d display device is that lens arra is arranged between display panel and the observer; Before generally being attached at display; Mainly the light of transmission display device is carried out the change of the direction of propagation, thereby realize the separation of right and left eyes information based on the light refraction principle.Traditional lens arra adopts the transparent material of refractive index greater than air, through design lens-shape curved surface, before utilizing micro lens technology to form fixing optical module to place display, thereby realizes three-dimensional stereoscopic visual effect.

The lens pillar know-why, as shown in Figure 1, this technology is the column lens array 4 that adds periodic arrangement in the outside of common liquid crystals display 1; The design of pixel 3 sizes of its design demand fluid,matching crystal display and viewpoint sees through refraction principle, with backlight 2 light that come out through pixel 3 through column lens array 4; Produce refraction,, utilize the pixel of LCD to show different images of left and right eyes images according to optical imaging concept; Let 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 will be changed the direction of propagation according to the difference of refractive index through the light of lens; The regions that the audience concentrates at the pixel light of images of left and right eyes image (left eye region 5 and right eye region 6) reaches the stereoscopic vision impression, thereby can realize that 3D (three-dimensional) shows.

The utility model is primarily aimed at the outer lens pillar blooming technology of pasting; The structure that has the liquid crystal indicator that contains the lens pillar blooming now is as shown in Figure 2; Comprise display panels 13, backlight 2 and the lens pillar blooming, display panels 13 comprises first substrate 9 and second substrate 11 that is oppositely arranged again, and (place, the left and right sides) applies envelope frame glue 10 between two substrates; Accompany liquid crystal layer 14 between two substrates; The outside attaching lens pillar blooming that the outside that attaches first Polarizer 8 and second Polarizer, 12, the second Polarizers 12 is 2, the first Polarizers 8 backlight is established in the outside of first substrate and second substrate respectively; This lens pillar blooming comprises second transparent optical film 7; The outside surface of second transparent optical film 7 is provided with some convex lens 4, and the material of second transparent optical film can be the high transparent optical film of PET (Poly Ethylene Terephthalate, polyethylene terephthalate) here.The light that pixel is come out is through convex lens structures; Produce refraction effect; The regions that the audience concentrates at images of left and right eyes image pixel light reaches the stereoscopic vision impression; Thereby can realize that 3D shows, application is electronic bill-board, DPF, hand-held product etc., and shortcoming is for tangible interference fringe phenomenon occurring.

The utility model content

The utility model purpose: to the problem and shortage that above-mentioned prior art exists, the purpose of the utility model provides a kind of 3 d display device, not only can realize that three-dimensional (3D) shows, can also effective optimization observe the visual angle and improve the interference fringe phenomenon.

Technical scheme: for realizing above-mentioned utility model purpose; First kind of technical scheme that the utility model adopts is a kind of 3 d display device; Comprise: display panels, lens pillar blooming and the anti-particle of dazzling; Said display panels comprises first substrate and second substrate that is oppositely arranged; The outside of said first substrate and second substrate attaches first Polarizer and second Polarizer respectively, and the outside of said first Polarizer attaches lens pillar blooming and anti-first transparent optical film of dazzling particle of outside surface coating successively.

Said lens pillar blooming can comprise second transparent optical film, and the outside surface of said second transparent optical film is provided with some convex lens.

Second kind of technical scheme that the utility model adopts is a kind of 3 d display device; Comprise: display panels, lens pillar blooming and the anti-particle of dazzling; Said display panels comprises first substrate and second substrate that is oppositely arranged; The outside of said first substrate and second substrate attaches first Polarizer and second Polarizer respectively; The outside of said first Polarizer attaches the lens pillar blooming, and said lens pillar blooming comprises second transparent optical film, and the outside surface of said second transparent optical film is provided with some anti-convex lens of dazzling particle that contain.

Beneficial effect: the utility model is in design lens-shape curved-surface structure; Before utilizing micro lens technology to form fixing film to place LCD, the equivalent refractive index that forms as condenser lens distributes, and the light (being the right and left eyes light path) of odd and even number row pixel is separated; Penetrate with different angles; Therefore right and left eyes will be seen different images in certain distance and angle, sticks simultaneously or adds to resist and dazzle (AG, Anti-glare) particle; Can effectively improve Moire fringe (interference fringe), thereby make the observer enjoy the stereoscopic vision impression that 3D brings more freely.The utility model is with the mode of pad pasting, can let common televisor, mobile phone and even outdoor billboard, can realize the bore hole 3D effect.The user only need stick pad pasting on the surface of screen, penetrates the refraction of the light of screen through pad pasting, just can realize the effect of bore hole 3D, better to satisfy multidigit observer's demand simultaneously.
