Children 3D Eyeware Projection light

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 metal screens, 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 size of the screen and the 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 the head. This is mainly to see the theater front and rear seat height difference design.

Contrast: the brightest part and the darkest part of the brightness difference.

Saturation: the degree of color, depending on the color composition and color components - gray ratio. Dolby stand-alone 3D has not only a problem of saturation, color reproduction has a problem.

Glasses weight: the more natural the better, especially the glasses light to facilitate myopia students set two glasses to watch (for the two eyes of different students, we must wear glasses, or dizziness). Circle Polarized Glasses (Real D, Dolby Dual 3D, Sony 4K 3D) <Linear Polarized Glasses (IMAX 3D) = Color Doors (Dolby Pro 3D) << Sync Shutter (XPAN-D) Sharpness: Depends on resolution Rate, that is, the number of pixels, the film format can be calculated using the number of film particles. The farther away from the screen, the less important the resolution. For the current commercial theater relatively high resolution range and relatively far from the viewing distance, the human eye is generally difficult to distinguish. So the importance of the last row.
