How to install a projection screen in the living room?
My home is not large, can I install a home projector? I don't have a special room to do the audio-visual room at home. Where do I buy a home projector? I have always advocated that projectors enter the ordinary family. One of the most important factors is that there are quite a few urban families living in the environment that can satisfy their own private theaters. On the other hand, in order to expand the influence, home projector manufacturers have also introduced a number of short focal length products to meet the needs of ordinary home users. For the average family, the living room is undoubtedly the best projector installation. Therefore, from the projection needs of most home projectors at present, as long as your living room is more than 4 meters, it can meet the requirements of installing the projector (for example, projecting a 100-inch screen). Of course, friends who are less than 4 meters in the living room are not able to install the projector, but the size of the projection screen will be reduced accordingly, and the impact of watching the movie is not enough. The projector is installed in the living room and generally has two installation methods: forward projection and side projection. Forward projection Just like the picture above, forward projection is the most common projection installation in an average home. The projection screen is on the side of the TV wall and the projector is on the side of the sofa. The advantage of this layout is that the viewers are in the same position when watching movies and when watching TV programs, but the biggest problem to be solved is how to make the curtain and the TV set together in front of the TV wall: the wall-mounted TV can't block the curtain. When the curtain is put down, it can block the TV screen, and it can't destroy the overall home decoration style. There are two key points to achieve this goal: First, the distance between the front end of the screen and the wall should not exceed 15cm after the TV wall is hung; the second is to open the curtain groove on the TV wall (the room decoration needs to be dug) . Regarding the first point, the LCD TVs currently using LED backlight technology can basically meet the requirements. The thickness of this type of TV body is generally less than 10cm, plus the thickness of the wall mount, the screen distance after hanging on the wall of the TV set. The distance between the walls can generally be kept within 15cm. If you buy a TV body with a large thickness, you can use the tape measure to measure the distance of the wall-mounted display TV from the wall before buying. The curtain groove on the TV wall is a very important part, focusing on the length, width and depth of the groove. This data is mainly to see the size of the curtain you are going to hang. The screen for the ordinary family living room is about 100 inches to 120 inches. Of course, the bigger the curtain, the more shocking the big picture will be, but it will still depend on the width of the room. The width of the general family living room (distance from the TV wall to the sofa wall) is about 4m, and the maximum projection size of most home projectors at this distance is 106 inches, so the screen size can only be 106 inches at most (if your living room is big enough) , you can also use a larger size curtain). The case that everyone saw, because the owner used a 100-inch curtain. The 100-inch curtain requires a screen slot length of 3 to 3.2 m, a width of 25 to 30 cm, and a depth of 25 to 35 cm. As long as the room size allows, it is recommended that you try to take the maximum value, because it can ensure that the curtain can be hidden in the slot, without affecting the home style, and easy to install the screen. Since the ceiling cannot be dug directly, the curtain groove can only be formed by the ceiling. It is only necessary to note that the top of the trough and the side against the wall are preferably the original cement wall, not the lightweight material used for the ceiling, as it is possible that the mounting surfaces are used to secure the anchor bolts in the mounting screen. If you are going to install an electric screen, you should also pay attention to reserve a power cord at the top of the slot and reserve a power switch control in the living room. This is very important, otherwise you will only be able to use the manual screen. Lateral projection The way to project sideways in the living room is common in many enthusiasts' families, the main reason is because they want a larger projection screen. The lateral projection screen is usually installed in the curtains of the living room, as shown above. Side projection has many advantages. Firstly, there is no problem of TV interference. The living room TV can be placed or wall mounted. Secondly, because the vertical length of the living room is generally large, a longer projection distance means that a larger size can be installed. The curtain. The last point is that because the curtain is installed in the curtain, when the curtain is lowered, it is equivalent to another layer of blackout cloth, which makes the living room more opaque. Lateral projection also has certain shortcomings. Accurately speaking, it should be insufficient: the layout of home theater audio needs to be changed. For example, the center speaker needs to be designed to be movable and easy to move. Home theater network decoration network welcomes you. Although the lateral projection does not require a TV set, it also has a requirement for the curtain groove. At this time, the curtain groove and the curtain track are grooved together, so it is conceivable to share a large groove. The specific size is recommended to be 40 to 50 cm in width and 25 to 30 cm in depth. The length of the slot is the longest depending on the length of the curtain and the length of the curtain rail. Taking a 120-inch screen as an example, the curtain requires a slot having a length of about 3.5 m. Similarly, since the weight of the curtain needs to be withstood, the top and side of the curtain groove at this time is preferably the original wall. If some decoration is used, thick planks are also required as the sides of the groove, and cannot be used. Gypsum board commonly used in ceilings. As with the forward projection, if you decide to use the electric screen, you need to reserve the power cord at the top of the screen slot, and the living room needs to reserve a switch to control the power on and off. Another detail to note is that since the curtain is installed in the curtain, the height of the curtain must be close to the ground, otherwise you will see a light leaking under the curtain when watching the movie during the day, greatly reducing the viewing time. effect. The installation of the above two projection screens in the living room is basically suitable for most families.
