[Home Theater Network HDAV.com.cn] Home theater screen is not a white cloth of the same size, the mystery of which is generally unknown to outsiders, today we will find out. Users need to match the appropriate projection screen according to the size of the room, the model of the projector and their viewing habits.
Is the home theater screen the same as the screen of a commercial cinema?
Using a projection screen will increase the sensory experience of watching a home theater, but if the screen is not suitable, it will be counterproductive. The screens in the home theater screen and the commercial cinema work the same way, either by projecting light from the front onto the screen or by projecting light onto the screen from the back.
Although the two projection screens have the same function and look similar on the surface, they are actually quite different, different in size, shape and arrangement. These factors will affect whether the screen can display clear and accurate images. effect. For example, some screens are good for bright rooms, but when all the lights are off, the effect is not as good as expected. The ability to adapt to ambient light is a key technology challenge for manufacturers, so this condition is the pre-requisite for what kind of screen to buy, in order to create the best quality home audio and video space.
The effect of ambient light on the screen:
Although sophisticated professional cinemas attract more and more viewers, at the same time, people are beginning to turn their home rooms or other empty rooms into home theaters. New products from other brands such as Vutec, Screen, Innovations, Stewart FilmScreen, Seymour Sceen Excellence, Elite Screens, etc., have become more adaptable to ambient light, even if the sun shines through the windows or the room to keep the picture bright and bright. Manufacturers call this technology "photo-rejection" technology, which depends mainly on the material composition of the screen.
Electric blind + screen combination:
There is also a “combat with light†trend that adds an addition to the main screen with a shading material. For example, the Stewart screen's Plexus multi-roller system uses a blackout curtain in front of the main screen, which automatically expands when the light is needed. Another example is the Elite Prime version of the screen, which uses an optical filter between the materials of the DartStar screen to absorb ambient light to improve contrast.
Uniform flatness of the screen:
In order to be able to make the screen appear the most dazzling picture under any lighting conditions, "uniformity" has always been the pursuit of good screen. Uniformity refers to the consistency of the projected image over the entire width plane, that is, the display is consistent whether in the middle or at the edge of the screen. The yield limit for uniform flatness is 0.8, and if it is lower than this threshold, the gain will not increase linearly. Another solution is to use an ultra-bright projector, because the brighter the projector's projection, the screen's reflectivity requirements will be reduced.
3D, 4K, 8K era:
A few years ago, the 3D screen was all the rage, and now it is starting to hype 4K. Manufacturers are taking the 4K route with great fanfare. The ultra-fine screen surface can handle the ultra-high-pixel projection of 4K projectors. After many years of mature ultra-fine screens have been improved and entered the market, the manufacturers soon It will start to pursue the 8K projector and screen.
On the surface, the projection screen is similar to the flat panel display, the design is slimmer, and the design is more and more popular. There is no narrow side or ultra narrow side design. This screen design style has an ultra-modern feeling and can better with the house. The structure and decoration style are integrated. For example, the screen slot can be parallel to the wall, into the cabinet or suspended from the ceiling. Another popular trend today is the curved screen and the deformable screen using a shadowing system.
A heart-warming "video wall":
American network streaming video sites like NetFlix, Hulu and Amazon Prime are similar to our domestic websites such as Youku, Tudou, and Iqiyi. Users can get a lot of videos when they raise their hands. The design style and size of the home theater screen are all in Follow the video source style of these video sites. With the choice of entertainment video more spatially, users are beginning to be keen on the "video wall", that is, playing several video programs simultaneously on the screen on the wall. This screen can be composed of several screen displays, or it can be a large screen. Divided into several quadrants, the "video wall" works by using a video stitching system, but this video stitching system is expensive because of its cutting-edge technology. This is not a concept with the picture-in-picture on our TV. The function of the video wall is very attractive. For example, sports fans can watch 4 games at the same time, for example, the user is also watching another movie in the same screen as the child. Playing games is very cool.
