Then, we defer to these two broad heading ray ban australia technology to carry on separately 11 introduced that first we have a look not to need to wear the special-purpose eyeglasses' open hole 3D technology. Tristar promotes does not need to wear the special-purpose eyeglasses' great size 3D monitor At present already had including Tristar's many monitor manufacturer promotes has exempted wears the specialized eyeglasses to be able to see the 3D three-dimensional picture the graphic display device, they biggest superiority is may the people not need to wear the effect which completely the eyeglasses can experience experience personally. Exempts the special-purpose eyeglasses 3D display technology image formation way .

This technology one is called "the open hole multiple-point" rayban australia the technology, also about cannot let two eyes through any tool from the screen see that has the parallax to two, to have the difference picture, will reflect the cerebrum them, the human will have the stereoscopic effect. It has also used the human eye parallax principle, through gives about the viewer two to send to the different picture separately, thus achieves the three-dimensional visual effect. Because observes may not wear the eyeglasses, therefore these technologies are suitable in the public place demonstration large screen monitor, is advantageous for the multi-people to watch. However, the open hole 3D display technology's shortcoming is also obvious: The people when watch the screen, must be located in the scope which, as soon as decides to be able to observe the three-dimensional picture, if is too far from the screen position, or the observation angle is too big, the 3D effect is not obvious. In addition, if is away from to the screen is too tight, the human will have the obvious dizziness phenomenon, therefore this technology has not suited temporarily on the light-sized monitor uses. In addition, this kind of technology is relatively bad in the demonstration effect aspect.

Recently, Kodak announced that has promoted one kind of new open discount sunglasses hole 3D display technology, with the preceding text in mentioned that what is different, Kodak issued this technology has used two high definition LCD display monitor's broad sight and the hypothesized phantom, this kind of table model monitor sight scope for 45°×36°, resolution for 1280×1024. However this kind of technology uses in manufacturing the video frequency game, molecular and chemistry model and so on many aspects, even more pays great attention the specialized level user. Because in the demonstration effect and the size factor, in the present 3D technology, the overwhelming majority technology through special-purpose 3D eyeglasses' auxiliary, like this can the 3D technology application on the light-sized tabletop liquid-crystal display, and can guarantee the 3D picture the effect. Believed that the majority readers most start to contact the exploded view are appreciate the 3D movie in the movie theater.
