Print Page6. During the installation, the distance between the polarizer and the projector should be over 5cm to avoid
thermal damage due to high temperature from the projector. Higher lumens projector will create more heat
and the distance should be larger. The polarizer can only tolerate up to about 60~70℃.
7. Pay attention to the HDMI compatibility due to different cables, equipment and connection distance. If the
distance is too long, HDMI extender shall be considered. It may extend the distance up to 50m to 100m.
Screen selection guide for 3D display
1. Silver Matte screen is required for polarized 3D display. Spectrum filter 3D system can use conventional
screen. Some factors are important in polarized 3D display screen:
i. The ability to retain polarization: higher value will have less ghost cross talk.
ii. Gain value: high value will have better brightness but may have viewing angle and hot spot issues.
iii. Flatness of the screen: Viewer may see wave screen and dis-alignment in geometry, especially in short
throw ratio projectors. It may be OK for 3D display but it will yield blurred image in 2D display.
2. The prices in different 3D screens have big range. Paint for 3D screen is available in the market.
3. If 2D & 3D display is required. User can select a screen with 2D/3D ability in the market.
4. Cheap silver paint and cloth with silver paste coating can be used as a temporary means to verify the
function of the 3D system if no 3D screen is available.
Projector selection guide for 3D display
1. It is necessary to select projectors with lens shift or keystone correction function for the image alignment.
2. A normal projector can be chosen for 3D display (no need to have 3D ready). Usually, XGA resolution will
create acceptable 3D video quality. A projector with higher native resolution, output brightness and contrast
ratio, will yield better performance similar to Movie Theater.
3. The output light from a projector with 3x LCD micro display (such as Epson) or LCOS (JVC or Sony) may
preserve polarization and the polarizer and glasses need to be carefully selected. Linear polarized system
can be used in most of Epson 3x LCD projectors. Optical spectrum type filter and glasses can be an
alternative in this case. DLP type projector is easier in polarizer and glasses selection.
4. The projector with throw ratio under 0.8 is not recommended because it will be more sensitive to the flatness
of the screen and create difficulty in image alignment.
5. DLP projector for business purpose may use different color wheel for higher brightness but degrade the
color performance. Please select video projector with HDMI or DVI input for home theater application.
6. For use in public area, the projectors with higher brightness should be considered. Projector with more than
3,000 lumens will be acceptable in limited ambient light presence. More than 4,000 lumens will create better
3D effect. Projector with full HD resolution and above 1,800 lumens will be recommended for home theater.
