The projection is hot! Talking about the selection of home theater curtains
The development of laser projection technology in the past two years has once again set off a boom in projector applications. The matching projection screen will naturally not be lonely, so the projection screen once again returns to our sight with a new attitude. For users who are not familiar with us, how should we choose?
Take the family home theater as an example. According to the environment built by the theater system, the choice of the screen is not complicated. It is clear that the choice of this type and the advantages of this type reflect the professionalism.
1, electric screen
The electric screen is currently the most widely used screen, its price is relatively low, easy to use, there are two kinds of control methods: wireless remote control and wired control. Generally, synchronous motor or tubular motor is used to control lifting, and the speed of slower lifting is synchronous motor. Fast is a tubular motor. The curtain material is generally made of white plastic cloth or fiberglass cloth material. Because of its low cost, white plastic screen is the most widely used in low-end curtains. Because of its material properties, glass fiber fabrics are often used in high-end curtains. The flatness of electric screens depends almost entirely on the curtain substrate. quality.
The other branch of the electric screen is the electric cable screen, which is made of flexible PVC material. Unlike the ordinary electric screen, on the two sides of the electric cable screen, there are two curved side wires to stretch the screen. , giving the screen a horizontal pulling force, plus the longitudinal pulling force of the hanging rod, thereby flattening the entire screen. This kind of curtain structure can ensure that the long-term use of the screen surface is flat as a mirror. Generally, it is mostly used for reflective optical screens with high requirements on the flatness of the screen surface. Because the structure and the production are complicated, the price is also high. There are some low-cost electric wire-drawing curtains on the market, which are often made of hard-white plastic or fiberglass cloth as the curtain surface. This kind of side pull line basically does not play the role of flattening, and it has its own form.
Under normal circumstances, in the "living room" or "bedroom" two scenes, recommended electric screen, according to the use of the living room and needs to raise or lower the curtain at any time, so the functional experience will not have an impact, and the overall decoration visually Gives the atmosphere, full of sense of science and technology.
2, the frame curtain
The frame curtain is a curtain that is stretched by a rigid frame through a connecting member (such as a spring, a drawstring, a fastener, etc.) to form a projection plane. The most common is the picture frame screen used in the home theater. A sturdy aluminum alloy frame stretches the screen surface. Because of its simple structure and mechanical principles, the screen surface can always maintain the best flatness, so it becomes a family. The theater's first choice.
There is also a picture frame screen, which refers to the screen style of the cinema, and the frame is designed to be curved, giving a superb image enveloping feeling, which is more common in the 2.35:1 screen. Because there is no corresponding standard in the industry, the arc screen of the home often refers to the arc ratio that is usually used in commercial theaters: the arc width is 5% of the screen width. Of course, to get the best display, it is essential to equip the projector with an anamorphic lens.
In view of the coexistence of various formats of the current video programs 4:3, 16:9 and 2.35:1, an electric variable-format frame frame has appeared, but the price is relatively high.
Some very large screens often use a steel frame or an aluminum alloy truss to build a large frame, and then the curtain is stretched on the frame with a rope, such as a large-scale event screen, a cinema screen, and the like.
Under normal circumstances, for a special room, such as the basement of a villa, such a professional "audio room" recommended frame frame, because it is different from the "living room", "bedroom" cross-use scene, audio-visual room It is used to enjoy as audio and video, so the immersion of this created theater can not be ignored.
