It is no longer a dream for a home theater to enter the home. As people live in surplus, the needs of spiritual life are not satisfied with the cinema display of only a small picture. The dream of people is to move the theater home. You can enjoy your favorite movies at home without leaving your home and it is a large screen of more than 80 inches. In addition to the projector speaker amplifier DVD in the home theater system, the curtain and the brothers that are inseparable from the projector are very important. Today I will talk about wide screen cloth.
I have been selling home theater equipment in AV for almost seven years. Some customers have suggested how to choose a curtain and choose which screen is right for me. I am not good at answering it for a while, because the question is more general, I can only give him advice based on his family's situation. Is the bigger the curtain, the better, the curtain in the living room, the proportion of the curtain to suit, the installation requirements of the curtain, etc., I will choose the conditions of the curtain and the previous installation experience and talk about it here.
There are two kinds of curtains, commercial and household. I mainly talk about home widescreen cloth.
Does the screen choose white or gray?
In fact, the curtains are usually made of white curtains and gray curtains (mainstream colors. Light gray, gray curtains, etc.). The choice of curtains depends on the size of the room, the degree of light obstruction, the height of the user's seat, and so on. Choose a screen to consider comprehensively. Don't fit in one aspect to meet the needs of one aspect.
Many of my friends asked very directly whether it was a good white screen or a gray screen. In fact, the simple talk about white or gray is very general. Because other materials can also make these two colors, which color is used is determined by the principle of brightness and contrast of the projector (from the perspective of the projector). The advancement of technology, the improvement of home projector technology, the black performance of LCD projectors is not gray, the continuous improvement of the chip, the contrast is getting higher and higher, you can choose the white screen. If the brightness is high, the contrast is not very high, the performance of the black is not very strong, and it is LCD. It is recommended that the gray screen can compensate for the shortcomings of insufficient black and black. If it is a DLP projector, you can choose a white curtain without special factors such as the environment. It has improved the vividness of color. If the light is not very dark and it is a living room, you can also choose a gray screen. The benefits of the gray screen, in addition to making it darker under black, add contrast, and it resists the reflected light from the environment. Choose what color is right, you should use the home according to your actual situation or consult a professional audio and video consultant to help you choose.
Is it appropriate to choose the form of the curtain?
In terms of common methods of installation, the curtains are mainly divided into drop-off curtains (manual and electric), frame curtains, and ground curtains. At present, the main pull screens and picture frames are mainly used in households.
The picture frame curtain, as the name suggests, is fixed on the wall like a painting. The general curtain is made of aluminum as a frame to stretch the curtain. This is the simplest type of screen setup, all you need to do is fix it to the wall. The advantage is flat. The disadvantage is that it can not be collected, it is easy to be dusty and polluted, and it is easy to oxidize and discolor (except for high-quality curtains) when exposed to the air for a long time. This is also the biggest drawback of this type of screen, because the position cannot be changed once installed. One advantage of a fixed installation projection screen is that it is usually not easy to wrinkle, which maintains a smooth, flat projection surface. This kind of curtain is suitable for a friend who has a dedicated audio-visual room and usually does not need to close the curtain. Another type of retractable screen can be a manual or electric motor controlled lift (electric screen). The advantage of the manual screen is that it is cheap and easy to install. It can be considered when the quality of the screen is not high. The shortcoming is that during the long-term use, the “V†type ripple will occur due to the central pull-down force and the like, which affects the flatness of the screen. Moreover, for home users, it is difficult to ensure that the curtain is in the same position every time, thereby affecting the picture effect.
The electric screen is the most common one among all kinds of products. The advantage is that the flatness is slightly better and easy to maintain. The curtain is evenly laid down from the two ends of the motor to ensure that the screen is not affected by external forces. It has easy lifting and easy to hide and install. It can maintain the smoothness of the curtain for a long time and does not generate ripples for long-term use. Usually this type of screen is more expensive, but people are still happy to use this type, after all, value for money. It is used in the living room (wall mounted TV and special wall (wall with window or special structure).
What is the ratio of the curtain?
The curtain can now be divided into: 4:3, 16:9, 2.35:1, etc. Here we generally talk about home wide screen 16:9 and 2.35:1 curtain. Some people say that the 16:9 projector buys a 16:9 screen, and the 4:3 buys a 4:3 screen. The projector and the screen correspond to the purchase, but the fact is not entirely true. But in general, the choice of a 16:9 screen for a home projector is the right choice. But what proportion of the screen you buy does not depend on the projector, but on the signal format that you usually play most often. This is because, as a projector, regardless of the proportion of the input signal, it can be projected normally. If you use a lot of movies, then 90% is a 16:9 picture (although there are a lot of 2.35:1, but the area with 16:9 subtitles can be displayed completely). I will single out the 2.35 ratio screen. Explain, then buy a 16:9 curtain.
The size of the curtain is chosen?
The first thing to be clear is that in the formation of a home theater, the size and pre-installation position of the curtain is the first consideration. The curtain can be hidden from the installation and the bright surface. If the installation is hidden, the size of the curtain should be considered. Once the size is determined, it cannot be changed.
Some people may say that the size of the curtain is of course as large as possible, if conditions permit. But this sentence should be viewed from two aspects. The first thing to be sure is that the bigger the picture, the more natural it is, but if the picture is too large, the picture quality will drop and the brightness will drop. To ensure picture quality, the quality of the projector is high and the price is relatively expensive. Generally, the size of the curtain is 80 inches to 120 inches, and the maximum is 150 inches. So how do you determine the size of the curtain? The first thing to determine is the width of the curtain wall, because for a 16:9 screen, the width is an important condition that limits the size of the curtain. Also consider that the speakers should be placed on both sides of the screen, and the speakers should be at least 15 cm away from the wall. Also look at your viewing distance. For example, the distance specification can be considered from 80 inches to 100 inches from 3 meters to 4 meters. If it is 4 meters to 5 meters, it can be considered from 100 inches to 120 inches. If it is 5 meters. A screen of 120 to 150 inches can be considered up to 7 meters (the farthest distance you can see). (except for special vision and keen perception).
Precautions to be installed in the early stage of the curtain. If you want to hide the curtain, you should consider the reserved screen slot. The size of the slot should be larger than the width and height of the screen. Also consider the installation and position of the power supply (generally the power supply is on the left side of the screen). For a 100-inch screen, it is necessary to reserve 3000*150*150MM for the 2600*150*150MM.120-inch screen. If there is a TV to leave the thickness of the TV, prevent the TV from blocking the curtain from unfolding. The top of the tank preferably covers the large core. For heavy curtains, it is necessary to pre-lay two large core plates for reinforcement. The manual curtains do not need to consider the power supply. If the frame curtains are to be inlaid with recesses, it is recommended that the grooves be larger than 5 cm of the outer frame of the curtain. installation.
The choice of curtains is not blind follow-up. It is necessary to choose the screen that suits you according to your actual situation. With the popular release of "Avatar" 3D movies in 2010, people's desire to introduce 3D movies into the family is getting stronger and stronger, and 3D screens are also bred. On the basis of the basic curtain, there are now curved curtains, sound-permeable curtains and 3D curtains. Customers choose more products, so customers must decide on their own situation and do what they can.
It is recommended that customers decorate the theater, if there is time to go to the professional home theater company to go to the site to see the demonstration (Fashion Video Experience Hall) can provide such services, learn about the latest audio and video dynamics, understand the configuration of home theater equipment, home theater Features of the device, specific installation precautions. I hope that the home theater shock screen will bring you a new visual enjoyment.
