Children 3D Eyeware Technical Parameters

Children's 3D glasses

Early 3D movies using red and green (blue) glasses, different colors of the lens filter out the corresponding color, so that we see a different image, this technology will not affect the screen effect is not complete, long wear, easy eyes Soreness.

The new children's 3D glasses technology mainly has the following standard:

1, IMAX standard: linear polarizer lens, the left eye horizontal polarized, vertical deviation of the right eye

Polarized glasses are the use of light characteristics, in the movie screen, the special emitter shows a 90 ° polarization angle of the screen. Two images polarized in different directions, while the glasses only accept the direction of the image, the combination of the brain to produce stereoscopic vision. Do not wear glasses to see the picture is overlapping image, some fuzzy.

2, X-PanD time-sharing system: also known as electronic shutter system

This technology is about the eyes of the screen alternately play, through the electronic signal synchronization, making the glasses corresponding to the left eye or the right eye a light, an opaque, alternating. Play the image and the frequency of the same glasses, you can see the three-dimensional image.

3, RealD spectral system: circular polarized lenses, 3D TV is now the mainstream standard, is currently the largest cinema system standard.

4, MasterImage spectral system: circular polarized lenses, has been RealD acquisition, no longer use this standard.

5, Dolby color system: red and green (blue) lenses of new technology improvements. Dolby 3D principle with the previous generation of red and blue 3D is the same system, but the effect is much better. In the ordinary digital projector on the installation of filter wheel and synchronization controller can be achieved, the cost is relatively low, and the filter wheel is easy to disassemble, but the higher the cost of glasses. The current use of the theater has been very little.

Reference to the technical parameters:

Brightness: The unit is lumens, largely depending on the projector's lamp power. The farther away from the screen, the more the brightness reaches the human eye. Do not consider the curtain, then the two systems better, and the single system is the problem is more serious (if you do not use the metal screen, XPAND only 2D movies 1 / 5-1 / 6, Dolby stand-alone 3D in 1 / 3-1 / 4). If you use a metal screen (such as RealD, Dolby dual-machine 3D, the specific circumstances, please contact the Studios), you can greatly improve the problem.

Visual deformation: the location of sight line of sight with the greater the angle of the projection light, the greater the visual deformation. The closest seat from the screening window is certainly the least. Visual deformation of the three-dimensional effect of the show is fatal. Sitting in a very partial position, will directly lead you to actually see the screen, with the projector projection of the original screen is very different, seriously affect the three-dimensional effect. So for 3D movie viewing, pick a good location is essential, even more than what to see the version is more important.

Field of view: one is the size of the screen in the field of view - depending on the screen size and distance from the screen; the other is the normal sitting position when the screen in the field of view is too biased - generally the last few rows of the middle position is the best. In addition it is best not to be blocked by his head. This is mainly to see the theater front and rear seat height difference design.
