Abstract
The utility model discloses a polarized three-dimensional (3D) liquid crystal display for improving viewing angle. The polarized 3D liquid crystal display for improving the viewing angle comprises a liquid crystal display, a pattern retarder and a lens, wherein the pattern retarder is attached on the liquid crystal display and the lens is arranged outside the pattern retarder. The pattern retarder of the polarized 3D liquid crystal display is provided with a lens structure, and therefore the polarized 3D liquid crystal display for improving the viewing angle utilizes light to produce refraction through the lens structure and enlarge crosstalk angle formed by correct pixel light. The viewing angle is enhanced and crosstalk is avoided, and therefore the polarized 3D liquid crystal display for improving the viewing angle can improve the viewing angle of the polarized 3D liquid crystal display and guarantee three-dimensional viewing effect.
Description
Technical field
The utility model belongs to the stereo-liquid crystal display device technical field, particularly a kind of polarization type 3D (three-dimensional) LCD.
Background technology
Existing stereo-liquid crystal display device is divided into bore hole formula and two kinds of technology of spectacle; Spectacle can be divided into active and polarization type again; Active optometric technology is mainly reached with the frequency upgrading of LCD scanning; The polarization type optometric technology is main to attach phase retardation film, and embodiment is for directly attaching phase retardation film on LCD, or phase retardation film is attached to earlier on the transparency carrier carries out the contraposition applying with LCD again.As shown in Figure 1; LCD generally comprises down Polarizer 1, first glass 2, be used for the pixel (being called " left eye pixel ") 3 of left eye, be used for pixel (being called " right eye pixel ") 4, second glass 5 and the last Polarizer 6 of right eye; Phase retardation film 7 is attached on the Polarizer 6; Phase retardation film is generally transparent gummy film of a slice 8 and the phasic difference plate 9 that is located in this transparent gummy film; Phasic difference plate and the corresponding setting of left eye pixel and right eye pixel, the light that penetrates from last Polarizer is polarized light, produces left rotatory polarization from the polarized light of left eye pixel through corresponding phasic difference plate and gets into the left eye glasses; Polarized light from the right eye pixel produces right rotatory polarization entering right eye glasses through corresponding phasic difference plate, and the beholder who wears anaglyph spectacles so just can see three-dimensional image.
But because the relation of glass or transparency carrier thickness, angle limitations is bigger.For fear of crosstalk (Crosstalk), the pixel that the phasic difference plate must be corresponding is little, and light has angle limitations through the phasic difference plate, after exceeding the visual angle, then can see incorrect pixel, crosstalks and will produce, and has influence on the effect of three-dimensional imaging.For example, in Fig. 1,, then can see, crosstalk from the light of left eye pixel if the right eye glasses get into the visual angle of left eye.
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 polarization type 3D LCD that improves the visual angle.
Technical scheme: for realizing above-mentioned utility model purpose; The technical scheme that the utility model adopts is a kind of polarization type 3D LCD that improves the visual angle; Comprise LCD, phase retardation film and lens; Said phase retardation film is attached on the said LCD, and said lens are arranged on the outside of said phase retardation film.
Said phase retardation film can comprise transparent gummy film and the phasic difference plate that is located in the transparent gummy film, and said phasic difference plate has a plurality of, and with LCD in the corresponding setting of pixel; The part of the corresponding phasic difference plate of said lens is concavees lens, and the part between the corresponding adjacent phasic difference plate is convex lens.
The material of said lens can be transparent natural gum.
The another kind of technical scheme that the utility model adopts is a kind of polarization type 3D LCD that improves the visual angle; Comprise LCD, phase retardation film and lens; Said lens are arranged on the said LCD, and said phase retardation film is attached on the said lens.
Said phase retardation film can comprise transparent gummy film and the phasic difference plate that is located in the transparent gummy film, and said phasic difference plate has a plurality of, and with LCD in the corresponding setting of pixel; The part of the corresponding phasic difference plate of said lens is concavees lens, and the part between the corresponding adjacent phasic difference plate is convex lens.
The material of said lens can be transparent natural gum.
Beneficial effect: the utility model corresponding phase retardation films configuration lens arrangement; The refraction that utilizes the rays pass through lens structure to produce; The angle of crosstalking that makes correct pixel light line form becomes big; The generation that so can make viewing angle improve and avoid crosstalking, stereo displaying effect is guaranteed at the visual angle that so can improve polarization type 3D LCD stereoscopic display.

Fig. 2 is the structural representation of the utility model embodiment 1;
Fig. 3 is the structural representation of the utility model embodiment 2.
Embodiment
Below in conjunction with accompanying drawing and specific embodiment; Further illustrate the utility model; Should understand these embodiment only be used to the utility model is described and be not used in the restriction the utility model scope; After having read the utility model, those skilled in the art all fall within the application's accompanying claims institute restricted portion to the modification of the various equivalent form of values of the utility model.
Embodiment 1:
As shown in Figure 2, the present embodiment difference with the prior art is: at the outside of phase retardation film configuration lens 10, the part of the corresponding phasic difference plate of these lens is concavees lens, and the part between the corresponding adjacent phasic difference plate is convex lens.Pass through lens again after producing left rotatory polarization or right rotatory polarization from the light of left eye pixel or right eye pixel after through the phasic difference plate of correspondence.Because the refraction action of lens, the visual angle of present embodiment is bigger than prior art, has improved stereo displaying effect.
Embodiment 2:
As shown in Figure 3, the difference of present embodiment and embodiment 2 is: phase retardation film and lens have exchanged the position: lens are arranged on the LCD, and phase retardation film is attached on the lens.Light from left eye pixel or right eye pixel passes through to produce left rotatory polarization or right rotatory polarization behind the corresponding phasic difference plate through lens earlier again.Because the refraction action of lens, the visual angle of present embodiment is bigger than prior art, has improved stereo displaying effect.
