Rear projection screen material

Rear Projection Screens

A UV or electron beam curing resin composition is applied to the molding surface of an emboss roll mold, and a sheet-shaped substrate is supplied to the emboss roll mold. Here's a YouTube Video of just the conceptualized function and not the practical application: The way they made the film puzzled me for at least six months but after several theories I settled on the one which entails a type of electrolysis process to deposit the cobalt though I cannot say for certain because I moved on.

Note that the wall can be lit to any color. Sharkstooth is a stretchy knit fabric. Each optical screen type gives you the freedom to choose between several features including enhanced contrast, brightness, resolution and image uniformity.

If you want the distortion this approach is good. The rationale behind this approach relies on having the image source placed near the audience, so that the audience will actually see the increased reflected light level on the screen. When setting up a rear projection keep in mind that the hot-spot of the projector is unpleasant to look at.

Screens with high gain also have a narrower usable viewing angleas the amount of reflected light rapidly decreases as the viewer moves away from front of such screen.

Black Diamond Film

We custom cut the film to the size you specify. More specifically, the hard coat treatment can be used to make the outermost layer of the protective resin substrate 41 or 61 resistant against external scratching or flaws.

An optical projection screen from dnp is not a traditional front projection or rear projection screen. Switchable projection screens can be switched between opaque and clear.

They are often used in home theater and professional environments where the screen does not need to be recessed into the case. Sample PS2 according to the present invention The sample PS2 was formed from a double-side lens sheet 20, first horizontal lenticular sheet 30 having a black light-shielding layer 35, and second horizontal lenticular sheet 50, as shown in FIGS.

This means that for the screen having the second horizontal lenticular sheet 50, the observer senses no incompatibility because the luminance gradually decreases from a certain viewing angle. Moire and sharpness A projected image was visually observed.

Some examples of this are planetariums and virtual-reality cubes featuring front-projection technology. The main material of the resin substrates 41 and 61 must apply rigidity to the horizontal lenticular sheets 30 and The geometric behavior of a grey screen is different from that of a white screen of identical gain.

These commonly use painted fabric that is rolled in the screen case when not used, making them less obtrusive when the screen is not in use. I've built unique functions into my coatings composition by selectively using a combination of materials whose refractive index allows for varying exit angles.

Viewers closer or farther away will see a pincushion or barrel distortionand the curved nature of the screen will become apparent when viewed off-axis. The protective resin substrate 61 is bonded to the front side of the resin substrate 51 via an adhesive layer This decreases the luminance brightness of both the projected image and ambient light, so while the light areas of the projected image are dimmer, the dark areas are darker; white is less bright, but intended black is closer to actual black.

Best colors for rear projection are light colors.

Gray Rear Projection Film Screen Material is the perfect surface to use when the situation does not allow projection equipment to be in front of the screen. The translucent gray surface works best with a bright projector (2,+ lumens) and narrower viewing angle/audience seating area.

Grey projection screen material is a matte, high comparison gray/grey surface area which provides a brighter image and also better contrast with deeper blacks in atmospheres with low ambient light concerns.

It works ideal with a brilliant projector (2,+ lumens). June 12, Totally transparent projection screens can now become part of interior architecture with the invention of a rear projection screen that looks simply like a piece of glass when it's.
