Frequently Asked Questions 2017-02-24T07:12:41+00:00
Q : Where can I buy the screen?? 2017-02-24T06:45:14+00:00

A :Go to the Contact Us and to check for distributors in your area. If there are no distributors in your area, please contact us  directly at this email address info@mocomscreens.com. If you are interested in becoming a distributor or dealer, please fill out the application found here .

Q : How do I adjust the screen angle for optimum light output? 2017-02-24T06:42:59+00:00

A : It’s easy. Start by adjusting the vertical angle of the screen so that the center of the screen is exactly perpendicular to the line drawn from the light source (projector).

Then, adjust the vertical angle for the highest brightness when observed from the main viewing positions.

※ Please refer to the “ Mocom concaved Screen Assembly & Installation guide

Q : How do I mount it? 2017-02-24T06:42:15+00:00

A : Screens below 150″ come with a fiberglass back-bracket that has two vertical rows of threaded studs set approximately 6″ above the centerline of the screen. These can be mounted on hooks which will allow the screen to be swung into the correct angle for viewing.

※ Please refer to the “ Mocom Screen Assembly & Installation guide

Q : What is the best viewing position? 2017-02-24T06:41:33+00:00

A :In general the best viewing position is behind the projector. The optimal viewing position is equal to or further away from the screen than the center of the sphere represented by the screen’s curvature. For the larger Mocom screens, the center of the sphere is approximately 19.5 feet from the face of the screen. However, a large number of our screens in use are actively viewed at shorter distances and still achieve very satisfactory results. Please be aware that as you get close to the screen, limitations in the projector such as– pixelation, etc. — become visible due to the sharpness of Mocom screens.)

Q : What projector do I need? 2017-02-24T06:40:47+00:00

A : It’s all depending on your needs. Bigger screen or brighter images will require higher lumens. We do not recommend short throw projectors because the curvature of the screen is calculated using a normal projector’s throw distance. For short throw projector’s, the curvature of the screen has to be calculated differently, so please check with us for more information if you need to use a short throw projector.

Q : Can I use Mocom concave screen (Solstice) in direct sunlight? 2017-02-24T06:21:59+00:00

A : We do not recommend that you to use them it applications where the sunlight will be at the same angle as the projector light source for obvious reasons or in wet or windy condition. The off-axis ambient light rejection of these screens is astonishingly high, allowing them to be used as billboards under full vapor lighting in trade shows and other public facilities.

Q : How do you clean a Solstice screen? 2017-02-24T06:21:11+00:00

A : Mocom concaved front projection screens have an ultra-fine grain which can pick up figerprint and dust. They can be cleaned using lint free cloth. In addition, you can use a hair dryer on COOL air to clean out the dust.

Q : What are the key differences between Mocom’s front-projection screens and conventional front-projection screens?” 2017-02-24T06:20:00+00:00

A :Mocom’s front-projection screens outperform conventional front-projection screens in every performance category. They provide higher gain, higher resolution, better contrast ratio, and better color accuracy than traditional screens. They also offer outstanding off-axis light rejection to allow them to be used in brightly lit spaces without the need for projector  shroud or similar devices. Another benefit of the perfect lens shape is that images at the center of the screen reflect back to the viewing audience as if they were coming from the screen itself.

 

Traditional paper and glass-bead screens are only primarily more suitable than Mocom screens in where the screens need to be rolled up (Mocom 18-23gain front-projection screens are solid lenses, so they cannot be rolled up.

This performance benefits of Mocom screens will  enable customers to place Mocom’s 18/23-gain screens into situations that previously would have required either rear-projection or video (e.g. plasma) displays.  Mocom screens far outperform rear-projection or plasma displays. In addition, they provide far lower maintenance costs.

Q : What are the Mocom concaved screens made of? 2017-02-24T06:17:52+00:00

A : The Mocom concave screens are made from multiple lay ers of aluminum film, pressed using precision-ground lens molds against a fiberglass backing material to provide contour stability and strength. Larger screens (150″ and larger) employ a steel frame for rigidity and mounting, while smaller models use an attached fiberglass back bracket for mounting.

What are the primary applications for these screens? 2017-02-24T06:15:44+00:00

A : Mocom’s front-projection screens are outstanding for public facilities, corporate training, gaming, and house of worship, and in home theater. A major application in development is dynamically-controlled advertising in public spaces.

Q : What are the cleaning instructions? 2017-02-24T06:44:27+00:00

Mocom’s Dupic screens can be simply cleaned with mild detergent and water, using a lint-free cloth.

Q : What are the key differences between Mocom’s Dupic dual projection screens and conventional rear-projection screens?” 2017-02-24T06:43:46+00:00

A :The Dupic film material has been specially formulated to provide exactly the same amount of reflection as transmission (50:50) while conventional rear screens have different brightness and clarity on each side. With Dupic screen, you don’t get the hot spots and corner fading found with other rear screen systems. The result is that for the first time 360° viewing is possible for projected images on glass panels suspended in mid-air. With no large box required behind the screen, weight and cosmetic issues are removed, and servicing is simplified to maintaining easy access to the video projector.

ANSI Lumen of projector 2017-02-24T06:53:05+00:00

ANSI lumen is a measurement of the overall brightness of a projector. ANSI lumen is calculated by dividing a square meter image into nine equal rectangles, measuring Lux (or brightness), reading at the center of each rectangle, and averaging these nine points. ANSI lumen is, in general, a more accurate measurement of  image brightness than other measurement techniques.
The brightness of the larger screen will decrease proportionally.
The brightness of the screen cannot be resolved by the brighter projector only.
Please contact Mocomtech for more information about the vivid, bright image.

Viewing angles of the screen 2017-02-24T06:53:11+00:00

Generally, the half-gain angle of the screen is defined as 50% of the value of the brightness of the image received in the center of the screen at a zero degree viewing angle. However, it should be applied for normal screens.
The specially designed Mocom Solstice screen with optical lens-like concavature is very different from normal screens. The viewing area of a Mocom Solstice screen must be considered accordig to the width of the screen and the maximum viewing distance.

Resolution of the screens 2017-02-24T06:53:17+00:00

The rough surface of the screen cannot express high resolution even with the HD projector.
The particles of the screen’s surface are required to be under 20micron for larger-than-100’’ for HD display.

Seam of the screens 2017-02-24T06:53:22+00:00

Generally, screens with a size above 100’’ have visible seam lines. It is important to check the thickness and the negative effect of the seams on the image.

Flatness of screen 2017-02-24T06:47:26+00:00

The screen’s surface must be flat to achieve uniformity of brightness and resolution.
When a roll-up screen is used for years, the screen’s surface will not have the same flatness and will look like it is curling.
Eighty percent of customers in the world use a fixed-type screen.

3D stereoscopic effect 2017-02-24T06:46:54+00:00

The 3D stereoscopic effect by the left and right viewing angle difference cannot be expressed on flat screens.
The Mocom Solstice Screen (lens-type concaved screen) or cylindrical (curved-type) screens are usually used in various types of simulators to achieve a vivid stereoscopic image.

What is a screen gain ? 2017-02-24T06:46:15+00:00

Screen gain is defined as the ratio of luminance produced by a projector’s beam of white, falling 360° onto the screen surface, compared with the luminance of reference standard with gain of 1.0 Reflectance (gain 1.0) measured on a tile of white carbon black.
Simply, the gain of white carbon paper is 1 and the gain of a mirror is 100.
Generally, asthe gain of the screen gets doubles, the price increases two to four times.
