OSI CO.,Ltd.

An unforgettable scene that remains in our hearts. There is a scene like that in the heart of every person.

We aimed at achieving the naturalness of that beautiful scene we keep in our hearts, without adding to or taking anything away from it…

Natural and beautiful images enhance the fascination of a movie even more.

Focusing on the naturalness of images and based on its unique “Pure Mat” concept (*1), OS SCREEN developed “Pure Mat II” for home theater users who require high image quality, thus winning their acclaim.
On this occasion, “Pure Mat II plus” comes on the scene as a new variation. “Pure Mat II plus” has been added to the product line-up as a screen that takes over the technology of “Pure Mat II,” changing the dark gray coating on the backside to a black coating.
(*1) The “Pure Mat” concept
The reduction of hot spots, color shifts and moire to the maximum, to reproduce natural images.

We believe that a real screen should diffuse as effectively as possible the light coming from the projector over a large area, in a uniform way, without irregularities.
As projectors increase their output power and definition, instead of using screens with high reflectance, we directed our attention to phenomena such as hot spots, color shifts and moire, which have an adverse effect on the enjoyment of images. In order to do this, we focused on the development of technology related to the perfect diffusion of light and random contextures.

In order to reduce “luster”, which is the cause of hot spots and color shifts, Pure Mat blended titanium oxide into the spaces between the fibers. As a result, the luster of the fibers was reduced, enabling perfect light diffusion.

Moire occurs due to the interference between the screen’s organized twill lines and the fixed-pixel projector’s pixel lines. In Pure Mat, besides selecting a fabric in which twill lines are indistinctive, a contexture created by warp and weft threads randomly interweaved is used. As a result, we succeeded in reducing moire to the extreme.

When the screen is placed in front of a window, there are cases in which outside light streams in through the window, striking the screen’s backside. In such cases, outside light counteracts the light projected on the screen, affecting the contrast of the images.
The most effective light-absorbing black coating has been adopted in “Pure Mat II Plus.”

OS SCREEN actively tackles environmental problems. It has acquired ISO14001 certification and conducts activities for environmental conservation. q⑰ure Mat is made of woven fiber, which we consider to be a material that has even less impact on the environment.

Please experience the pleasure conveyed by our flagship screen, recommended with confidence by OS SCREEN.
