More and more players and friends have realized this point. A good projection screen is important for improving the quality of movies. Many practical experience has proved that an ordinary home projector will have a better effect on a good screen. The effect of hitting directly on a white wall is much better. After understanding the importance of screens, many entry-level friends don’t know which screen to buy. They are afraid that buying a bad screen will not improve the quality of the screen, but will waste money. Let’s talk about the consumers in the purchase process. Let's talk about the questions we have received, hoping to be a reference for your purchase. 1. What are the mainstream screen types of home projection screens at present? To solve this problem, it is mainly distinguished from the material. At present, the most popular and mainstream in the home projection field is undoubtedly the white plastic screen, because the price is relatively cheap, and it has the characteristics of true color reproduction. 2. What are the mainstream screen brands in the home projection market? Stewart (viewer special), kikuchi (Kikuchi or Kikuchi), OS (Aoaisi), Liping, Da-lite, Meishi, SNOWHITE(), etc. 3. What is a gray screen? What is a gray screen is believed to be a problem that bothers the most friends. In fact, gray screen is not a new type of screen independent of white plastic screen, glass bead screen or metal screen. In fact, it is more inclined to say that it is a new technology-'gray screen technologyAny type of curtain can actually be made into a 'gray screen' through the 'gray screen technology'. Therefore, the 'gray screen' can include a gray screen with a white plastic screen, a gray screen with a glass bead screen, or a gray screen with a metal screen. However, through the 'gray screen technologyGray screens are often referred to as 'high-contrast screens' because they were originally designed to improve the contrast of data projectors in a lighted audio-visual room environment. Its working principle is: the gray screen uses gray paint to absorb more environmental interference stray light than the white screen, so that the black of the picture becomes darker due to the interference of the ambient light, and the white of the picture is basically not lost. It is well maintained, which directly causes the gap between black and white contrast on the screen to increase, so as to achieve the purpose of improving the contrast. 4. Is the image quality of the gray screen necessarily better than that of the white screen? Not necessarily, it depends on the situation. There are good and bad gray screens. High-end and high-quality white screens will have better effects than low-end gray screens. To do a good gray screen, a certain technical content is required. Not every brand can launch a good gray screen. 5. The installation method will affect the choice of screen type? If the projector is ceiling mounted, it is best to buy a reflective screen. If the projector is installed locally, such as on a coffee table or low table, it is best to use a retro-reflective screen. Diffuse reflective screens are suitable for both hoisting and floor mounting, and diffuse reflective screens are generally white plastic screens at low prices and are affordable by more users, so they have become the mainstream. And even 'gray screens' are more popular with white plastic screens. 6. How to determine whether you want a 16:9 screen or a 4:3 screen? Many people are troubled by this problem. Some people say that you buy a 16:9 screen for a 16:9 projector and a 4:3 screen. For the 4:3 screen, you need to buy the screen corresponding to the screen. This sounds the best, and the utilization rate is high. However, I believe that the ratio of the screen to buy is not directly dependent on the projector, but depends on your usual time. The most frequently played signal format. In other words, what do you use the projector mainly for? If you mostly use it to watch DVDs, 90% of DVDs are now 16:9 screens (although there are many 2.35:1, but the 16:9 area including subtitles can be fully displayed), then buy a 16:9 screen; If you mainly play games and the resolution supported by the game is still 4:3, then buy a 4:3 screen. Don't be afraid to take both into consideration. The 4:3 screen can also display the 16:9 screen, but there are some areas on the top and bottom of the screen that are vacant. The 16:9 screen can also display the 4:3 picture, and it is also possible to vacate the left and right parts of the screen. To make full use of the screen, the screen ratio is determined by the information sources you use. 7. How to determine the size of the screen you need? The size of the screen generally refers to the length of its diagonal. The size of the projection screen should be determined according to the size of the theater space. Generally speaking, a room with an area of u200bu200b20 square meters or more can choose a screen of 100 inches or more; a room of 15-20 square meters can choose an 80-100 inch screen; for a room of 10-15 square meters, a 60-80 inch screen can be selected. . Because the best viewing position for the front projection should be at a distance of about 1.5 times the diagonal size of the screen, that is to say, if it is a 100-inch 4:3 aspect ratio screen, the position of the seat from the screen should be About 3.8 meters (100*0.0254*1.5). If the distance is too close or the screen is too big, it will cause the eyes to keep turning when watching the movie because they can't come over, and it will be very tired after a long time. 8. How to correctly calculate how much gain you need? The formula is: current white wall gain 1 / current screen area u003d expected screen gain / expected screen area. The function of the formula is as follows: After starting the projector, directly cast it on the wall and use it for a period of time to maximize the performance of the projector, and then adjust the size of the projected screen to see how big the screen can be obtained by adjusting the size of the projected screen. The picture quality, of course, can be as large as possible, but you must keep the picture quality within the range you think you are satisfied with, and then measure the current picture size.
