Caramel's newest fiberglass Matt White
Caramel to create new types of projector screens-fiberglass Matt White
For most users who just came into contact with the projector, projector screens tend to be a little knowledge, the most overlooked, even considered dispensable, even if the projection screen on the white wall, too, can enjoy the movie. In fact, this kind of thinking is very wrong, the reasoning is like amplifier matching speakers, a good amplifier, to fully demonstrate its advantages, must be rendered through a good set of speakers, but also different speaker sound can vary widely.
Projector screen mix that is very similar. From the optical point of view, it is not difficult to understand, no matter what projector, projecting out of the image, is through a projector screen has developed in the reflection of light to the human eye. As the projector screen is a receiving surface, from a physical point of view is passive and therefore different curtain material and viewing angle, light reflection intensity, spectrum and transmission modes have different, such images have difference reaches our eyes. For home theater demands, among other things, images not only to see clearly, also in brightness, contrast, color, detail and noise have higher requirements. So not only requires to for a good projector, a suitable projector screen, with a properly, attributes can cater for the different nature of the projector, projecting out to maximum image quality improved and modified, as projector advantages play out.
Also because of this, the projector screen come out already for more than a century, but still continues to develop new materials, new processes, pursuit of a more perfect results.
In General, before you choose a projector screen, you need to understand the projector screen on top of several technical indexes, including gain, perspective, proliferation, etc. First, the gain is reflecting the projector screen reflecting projection light indicator. In the projection angle must, projected light flux invariable situation, projector brightness on the screen in one direction and the brightness ratio of the ideal State, is called the luminance coefficient in the direction, called a projector screen gain maximum value. Usually as a matte white wall gain 1, gain projector screen is less than 1, weakening spot light; if the projector screen gain is greater than 1, more projection will be reflection or refraction of light.
Different materials, gain varies, usually Matt white screen gain at around 1, common grey screen gain of only 0.8~0.9, and glass bead screens gain can be as high as 2.8~3. Followed by perspective. Projector screen reflection is different in different directions. In the horizontal direction, as far away from the center of the screen, lower the brightness; when the brightness falls to 50% viewing angle, defined as the angle.
Watch images in perspective, brightness is satisfactory; viewing images outside of the angle, brightness is not sufficient. As regards the proliferation, depends largely on the projector screen material type.
Three most common projector screen materials including white plastic curtain, silver Pearl and glass bead projection screen projector screen, their optical characteristics are not the same. Matt White projector screen is diffusion, in theory, all displays gain value in the direction of (GS) is 1, but its real value is close to 0.9. When it is used in the home environment, you can avoid infiltration of external light and indoor light control and reflect light to create the best projection environment, so as to achieve the most satisfactory result, evenly spread the light is one of the most important functions of the projector screen.
Glass bead projection screen is the return type, the reflection characteristics of the projector screen is somewhat similar to the optical characteristics of reflective road signs, road signs at the front of the light exposure is very bright. When ray casting glass beads on, the light will return, in short, the maximum radiation intensity returns to the light source, or projector. This type of screen gain (GS) is approximately 1.5 to 3. View images from the close to the projector, a good method for evaluating performance projector screen, note with the optical axis of the projector, left, at the corner of 20-30 and image seem darker than the white projector screen.
Increase the incidence angle of the projector, glass bead projection screen will reduce the harmful rays returned to the viewing position. Silver Pearl screen is reflective of the projector, projector screens of this type provides the greatest radiation intensity, like mirror-reflected light. Projector screen gain and spread interactive, if inadequate diffusion of light, you can obtain a higher projector screen gain value, but easily noticeable bright spot. If projectors and viewers get more distant, the projector can be set looked like a mirror on the achievements, screens of this type may be a good choice. Silver Pearl projector screen gain wide, from 1.5 to 10.
The projector screen brightness high, but gains a higher value, the cost is the narrower the angle.
Integrated advantages and disadvantages of these various acts, together with the company exported to European and American markets with many years of experience, caramel company uses the latest technologies in Europe and America, and launched the new page of projector screens: fiberglass Matt white screen! Fiberglass Matt white screen in Matt White original made by special technology on the basis of processing.
In Matt white screen on the basis of merit of reservations, bridge differences and adds the following several points:
1, first of all moisture mildew, does not turn yellow after uses storing for a long time, curling.
Up plain white plastic bead is durable.
