Abstract
The utility model relates to a liquid crystal light valve for stereoscopic glasses, which is used for improving the watching effect of a stereoscopic television or film. The technical scheme is as follows: the liquid crystal light valve is formed by using two glass plates to clamp liquid crystal at the middle part; one surface of the glass plate, facing the liquid crystal, is provided with an ITO film and PI directional materials in sequence, and the other surface thereof is stuck with a polarizer; the thickness of the liquid crystal is 6 micrometer; and the twist angle of the two layers of PI directional materials is 120 degrees. The liquid crystal light valve improves all the properties of the stereoscopic glasses by optimizing all the special values of the box thickness of the liquid crystal light valve, the liquid crystal twist angle and the refractive index, leads people to be capable of watching clear and vivid three-dimensional stereoscopic films, stereoscopic televisions and stereoscopic games comfortably and leads the people to obtain the great vision enjoyment.
Description
Technical field
The utility model relates to a kind of liquid crystal light valve (single-pixel liquid crystal display) as the crystal glasses eyeglass, belongs to optical technical field.
Background technology
In order to reach visual effect on the spot in person, strengthen the sense of reality, people have invented three-dimensional film, stereotelevision, stereo game.But watch the 3D picture, need wear the 3D glasses, crystal glasses is exactly wherein a kind of.During crystal glasses work, two eyeglasses alternate conduction under the driving of synchronizing circuit, make left eye and right eye alternately watch image, what just left eye was seen is the left side picture, what right eye was seen is the right side picture, and promptly the switching frequency of left and right sides liquid crystal lens has cooperated left and right sides picture presentation speed, and this speed is very fast, can produce stable persistence of vision phenomenon, so in brain, just produced the stereoscopic picture plane effect.The key member of crystal glasses is the liquid crystal glasses sheet, traditional liquid crystal glasses sheet adopts conventional liquid crystal light valve, it is the single-pixel liquid crystal display, as TN type LCD (distortion angle 90 degree), HTN type LCD (distortion angle 110 degree), STN type LCD (distortion angle 220 degree, 240 degree) etc., because unreasonable structure, it is improper that each parameter is selected, viewing effect is had a greatly reduced quality, the poor definition that has, the stereoscopic sensation that has is not strong, have in addition cause image fault.Therefore, the structure of liquid crystal glasses sheet is improved, made people can see that stereo-picture clear, true to nature is very important.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, provides a kind of rational in infrastructure, the anaglyph spectacles liquid crystal light valve that viewing effect is good.
The purpose of this utility model realizes with following technical proposals:
A kind of anaglyph spectacles liquid crystal light valve, be made of the liquid crystal in the middle of the two sheet glass sheet double teams, glass sheet is disposed with ito thin film and PI directional material towards the one side of liquid crystal, and another side posts polaroid, the thickness of described liquid crystal is 6 microns, and the twist angle of two-layer PI directional material is 120 °.
Above-mentioned anaglyph spectacles liquid crystal light valve, the refractive index anisotropy of described liquid crystal are that Δ n value is 0.108.
Every performance that the utility model is thick by the box of optimizing liquid crystal light valve, liquid crystal twist angle and refractive index anisotropy value improve anaglyph spectacles, allow people can cosily watch three-dimensional film clear, true to nature, stereotelevision and stereo game, make people obtain great visual enjoyment.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Each label is among the figure: 1, PI directional material; 2, ito thin film; 3, liquid crystal; 4, glass sheet; 5, polaroid; 6, edge sealing frame.
Embodiment
Referring to Fig. 1, the crystal glasses sheet is a kind of liquid crystal light valve, has the essential structure of liquid crystal display device.Usually liquid crystal display device divides TN type, distortion angle 90 degree; The HTN type, distortion angle 110 degree; The STN type, distortion angle 220 degree, 240 degree.
Through macromethod, research, grope and test discovery, liquid crystal display device also is not suitable for anaglyph spectacles usually, and the liquid crystal light valve that is used to make the crystal glasses sheet should possess following feature:
1, adopt 6 microns box thick, the twist angle of 120 degree.
A large amount of experiments show, box is thick during less than 6 microns, and three-dimensional level is not obvious, and stereoscopic sensation is just not strong, and box is thick during greater than 6 microns, and stereoeffect is too strong, stiff, the distortion of picture.Similarly, the twist angles less than 120 degree will make stereoeffect become not obvious, and twist angle occurs distortion again, anamorphose when spending greater than 120.
2, the refractive index anisotropy is 0.108.
Light is a kind of light wave, and light is the form side-to-side vibrations with ripple, and propagates forward.The distance of side-to-side vibrations is the speed of vertical direction, and velocity of propagation is the speed of parallel direction.The light velocity of vertical direction and the light velocity of parallel direction have the speed difference, and it is that Δ n finishes that control is leaned on the refractive index anisotropy of liquid crystal by the vertical light velocity peace row light velocity difference size of the light of liquid crystal layer.Obviously, only make vertically and mate, just can not make light produce unusual distortion with the light velocity of parallel two branches.Be the big again or littler unusual distortion that can produce light of Δ n, all be unfavorable for improving viewing effect.
In addition, optimize the threshold voltage of chromaticity coordinates, polarization efficiency and the liquid crystal of polaroid.
Chromaticity coordinates, the polarization efficiency of polaroid integrate, and simply say to be exactly the color of polaroid, the color of liquid crystal display just, and it has determined human eye to accept the color really degree of light.As everyone knows, see the very clear of thing color identifying daytime, if yellow or other have under the color light and see thing, it is different that color relation and daytime are seen, color distortion.So we optimize chromaticity coordinates and polarization efficiency, the result of optimization is that to select model for use be the polaroid of EGW1225DUHC.
Liquid crystal glasses sheet essence is exactly a liquid crystal display, the blackening of an energy integral body, the liquid crystal light valve screen that bleaches, and the incidental Circuit Matching of liquid crystal light valve and glasses produces stereoeffect.Liquid crystal glasses institute making alive is high more, and LCD panel is black more.If the glasses black and white alters a great deal, human eye can be subjected to very big stimulation, and is very uncomfortable.Have only black and white to change when suitable, it is comfortable that human eye could be felt.Experiment shows, selects 1.6 volts of threshold voltages the most suitable.
