Abstract
The utility model is suitable for the display technology and provides a 3D liquid crystal display system. The system comprises a frequency doubling liquid crystal display and a liquid crystal light-valve spectacle, wherein a 1/4 wave plate is attached on the outer side of a plane-polarized light piece of a light emitting surface, the frequency doubling liquid crystal display and the liquid crystal light-valve spectacle are synchronously driven, and the 1/4 wave plate is attached on the outer side of the plane-polarized light piece of a light incoming surface. In the utility model, a piece of 1/4 wave plate is respectively added on the outer side of the plane-polarized light piece of the light emitting surface of the frequency doubling liquid crystal display and that of the light incoming surface of the liquid crystal light-valve spectacle, so that the ray is transmitted in a circularly polarized light manner between the frequency doubling liquid crystal display and the liquid crystal light-valve spectacle; and because the vector direction of the circularly polarized light twirls and represents isotropism, so even if human head swings horizontally, the brightness changing of an image seen by human eye does not appear, the problem of color distortion is correspondingly improved, the 3D display effect is not affected, and a spectator doesn't feel fatigue.
Description
Technical field
The utility model belongs to the display technology field, relates in particular to a kind of 3D liquid crystal display systems, liquid crystal light valve glasses, 3D LCD.
Background technology
The realization principle of wearing the 3D display system of liquid crystal light valve glasses is to show the right and left eyes anaglyph by frequency multiplication LCD (refreshing frequency is more than 120HZ) timesharing, light valve glasses and LCD driven in synchronism, when the frequency multiplication display shows left-eye image, left eye liquid crystal light valve glasses are opened, right eye liquid crystal light valve glasses cut out, and the left eye liquid crystal light valve cuts out when in like manner showing eye image, and right eye liquid crystal light valve glasses are opened, the image that right and left eyes is seen melts picture through brain, forms the 3D vision.
Fig. 1 shows the theory of constitution of common liquid crystals light valve spectacle 3D display system, the light transmission shaft design of the face polaroid of frequency multiplication LCD 1 and the face polaroid 21 of liquid crystal light valve glasses 2 is in same direction, posture to spectators has strict requirement, just can see 3D rendering preferably when having only head to move horizontally with vertical moving, if head swings, the light transmission shaft of the light transmission shaft of frequency multiplication LCD 11 and face polaroid 21 is not in same direction, the big subordinate of brightness meeting of the image that human eye is seen falls, color also can distortion, what promptly see is not best 3D rendering, if and keep a posture to watch for a long time, be easy to cause fatigue.
The utility model content
The purpose of this utility model is to provide a kind of 3D liquid crystal display systems, liquid crystal light valve glasses, 3D LCD, be intended to solve when watching 3D to show by the liquid crystal light valve glasses to spectators watch posture strict, be easy to cause tired problem.
The utility model is achieved in that a kind of 3D liquid crystal display systems, comprising:
The frequency multiplication LCD, the outside of the face polaroid of its light-emitting face is with a quarter wave plate;
With the synchronously driven liquid crystal light valve glasses of described frequency multiplication LCD, the outside of the face polaroid of its light entrance face is with a quarter wave plate.
Further, described frequency multiplication LCD is a TFT type LCD.
Further, described liquid crystal light valve glasses are twisted-nematic TN type LCD.
Further, described liquid crystal light valve glasses are optical compensation curved OCB type LCD.
Further, the face polaroid of the light-emitting face of described frequency multiplication LCD and the quarter wave plate that is attached to this face polaroid outside are integrated into an optical compound film.
Further, the face polaroid of the light entrance face of described liquid crystal light valve glasses and the quarter wave plate that is attached to this face polaroid outside are integrated into an optical compound film by one.
The utility model embodiment also provides a kind of liquid crystal light valve glasses, is pasted with a quarter wave plate in the outside of the face polaroid of its light entrance face.
The utility model embodiment also provides a kind of 3D LCD, is pasted with a quarter wave plate in the outside of the face polaroid of its light-emitting face.
The utility model increases a quarter wave plate respectively by the outside at the face polaroid of the light entrance face of the face polaroid outside of the light-emitting face of frequency multiplication LCD and liquid crystal light valve glasses, light form with circularly polarized light between frequency multiplication LCD and liquid crystal light valve glasses is propagated, because the direction vector of circularly polarized light is atwirl, show as isotropy, even the head part swings like this, light and shade can not appear in the image that human eye is seen yet to be changed, the cross-color problem also can correspondingly be improved, the 3D display effect is unaffected, and it is tired that spectators are not easy to feel.
Description of drawings
Fig. 1 is the theory of constitution figure of the common liquid crystals light valve spectacle 3D display system that provides of prior art;
Fig. 2 is the theory of constitution figure of the liquid crystal light valve spectacle 3D display system that provides of the utility model embodiment.
Embodiment
In order to make the purpose of this utility model, technical scheme and advantage clearer,, the utility model is further elaborated below in conjunction with drawings and Examples.Should be appreciated that specific embodiment described herein only in order to explanation the utility model, and be not used in qualification the utility model.
Among the utility model embodiment, on LCD face polaroid, increase a quarter wave plate, the linearly polarized light of LCD outgoing is become circularly polarized light, simultaneously also increase a quarter wave plate, the circularly polarized light of incident is become linearly polarized light realize analyzing in the face polaroid front of liquid crystal light valve glasses.
Fig. 2 shows the theory of constitution of the liquid crystal light valve spectacle 3D display system that the utility model embodiment provides, and for convenience of description, only shows the part relevant with the utility model embodiment.
With reference to Fig. 2, in the outside of the face polaroid of the light-emitting face of frequency multiplication LCD 1 with quarter wave plate 11, quarter wave plate 11 becomes the linearly polarized light of frequency multiplication LCD 1 outgoing into circularly polarized light, liquid crystal light valve glasses 2 and frequency multiplication LCD 1 driven in synchronism, in the outside of the face polaroid 21 of its light entrance face equally with a quarter wave plate 22 that is used for analyzing, quarter wave plate 22 becomes the circularly polarized light that receives into linearly polarized light and is incident to human eye by liquid crystal light valve glasses 2, because the direction vector of circularly polarized light is atwirl, show as isotropy, even the head part swings like this, light and shade can not appear in the image that human eye is seen yet to be changed, the cross-color problem also can correspondingly be improved, the 3D display effect is unaffected, and it is tired that spectators are not easy to feel.
Further, the face polaroid of quarter wave plate 11 and frequency multiplication LCD 1 can also be integrated into an optical compound film, have the effect of polarisation and phase compensation concurrently, specifically can divide the mode of layer growth to realize by bonding or crystal, the optical compound film after use integrating when fitting to the light-emitting face of frequency multiplication LCD 1 with convenient.In like manner the face polaroid 21 of quarter wave plate 22 and liquid crystal light valve glasses 2 also can be integrated into an optical compound film.
