With display technology continues to progress, people are increasingly seeking greater picture screen. Traditional CRT and the monitor's size from 9 inches to 47 inches back is very difficult to develop. The simultaneous occurrence of LCD, plasma display and rear-projection machine, etc, the maximum screen size and also although 60-70 inches. In pursuit of greater dimensions, people turn our gaze to the screen of up to 300 inches above the area of the projector.
With CRT cathode ray tube projector to be eliminated, the popularity of LCD projectors LCD and DLP digital projector in the emerging, the volume of the projector getting smaller and smaller, lighter weight and more from the original hundred kilos to lightest are insufficient 1.3 kg, more and more portable; the increasingly high picture quality and sharpness, contrast ratio from 200: 1 to present 1600: 1, resolution is as high as $ 2500 * 2000, more uniform color, sharpness and higher; manipulation easier; price cheaper, from past 1000 lumens more down to the present lack of proofreading, 1500 lumens; function from a single display to present multiple data inputs, picture-in-picture and seamless source switching; the lamp service life is longer; brightness from past centuries lumens, up to now, even tens of thousands of lumens lumens. Barco company in April 2003, published in the United States LasVegas Convention Center and shows 3 tablets DLPTM technology based, brightness up to 10, 000ANSI lumens projector. Judging from the many projector brightness is pursuing the goal of one of the most important goals.
Projector image material carrier-projection screen is to focus on its brightness gain the pursuit of goals. The early centuries lumens projector only in a dark environment presentation screen, glass bead screen and white plastic screen brightness gain than its already quite satisfactory, to gain the advantage of nearly 2 brightness eliminated gain less than 1 in white plastic curtain. But as the projector lumens, in bright environment projection has become the needs and potential. And glass bead curtain is designed for dark environment, in a bright environment, glass bead makes glass bead screen produce strong mist white background, the background nearly projector pursuit of colourful all attempts. So there is no atmospheric light mist white background beauty creation metal screen appears.
Metal screen English name "Super Wonder-Lite". Literal translation is "Super, another surprising ore". Only view its impracticality its effect is not generic. Tatsu metal hard screen in addition to the extra long life and resistance characteristics of dirty, its high brightness (spherical gain up to 7-8) and color reproduction (in atmospheric light no mist white background) made a deep impression. Tatsu metal hard screen is more suitable for the more fixed without mobile specific occasions.
Due to a variety of highly reflective metal beauty invasive metal soft screen is the optical, chemical, metallurgy, mechanics, physics, fluid interfaces, multi-layer printed and coated, polymer materials, producing high-tech products. The gain and perspective are not lower than the flat metal hard curtain. In view of its installation, ease of use, portability, more suitable in light of the classroom, conference rooms, etc.
