1. The viewing distance of the viewing space is below 4 meters, and the LCD TV is directly purchased;
The viewing distance is more than 4 meters. The reason is very simple. If you want to go to the cinema, we all choose the middle position, because the size of the screen is related to the best viewing distance.
If you are in the viewing room to the projection wall or the TV is below 3 meters, congratulations, you don't have to die too many brain cells, and decisively choose an ultra-thin LCD TV to go home.
2, the experience of watching the experience if 70 inches can satisfy your stomach, it is recommended to buy LCD TV, because this Size is now mature LCD, not afraid of light, and durable.
More than 70 inches of large screen, even 300 inches in the giant screen, you only need LCD TV and projection cost on the balance, the projection is 70-inch start, the giant screen is the projection of the trump card, the home theater does not have a big screen The best show is no good.
Living in the era of reading screens, the TV and tablet of the home have long been a display. The mobile phone has solved almost all my entertainment and information needs. Without a mobile phone, it can't live like oxygen, but holding a 5.5-inch screen to watch movies. Really heartbreaking, I can't find the feeling of watching movies in the theater. I miss the theater in a dark, full-heartedness, and I am relaxed. This is the mobile phone has wiped out a lot of traditional digital products, but in the giant Screen viewing is always a small one.
3, the purchase budget is below 5,000, decisively buy LCD TV, within 5000, it is impossible to buy the necessary combination of 1080P projection + curtain. The relationship between the projector and the curtain is like the relationship between fish and water. If it is not equipped with the corresponding professional curtain, it will definitely be full of grass mud horse after booting. I have a deep understanding, haha...
With a budget of 5,000 to 10,000, you can consider the ultra-short-focus projection of the LED light source of DLP imaging technology, which is perfect and inexpensive;
If you have a budget of more than 15,000, you can consider the projection of high-brightness LED or laser light source. With a budget, you can fly in a wide sky, you can choose laser TV + screen + sound system + K song system....., I feel a bit off the mark, haha ;
4, family members this is mainly to consider the elderly will not operate the projection, if the family has young people and children do not have to worry about operational problems. Just like our family has an old man, the living room hangs a 65-inch Sharp, and the projection is placed in the bedroom, so I want to make a picture. Unfortunately, if the home is too messy, it will not disgust everyone:)
LCD TVs are now very popular, and which brand TV is good, everyone already knows. In China, before 2010, just like the second lady of the local family, it would be a good day to look at it. The price is too high, it is not affordable for the masses. The projection is mainly commercial, which makes the general consumer strange to the projection. .
With the rapid development of projection technology, the projection cost is greatly reduced, the market price is very close to the people, and the popularity of mass consumption has soared, the projection has begun to attract the attention of many families, but how to choose the projection is still foggy, I have done it below. Share your homework and help everyone have a basic ability to identify:
First, the projection ratio, simple understanding is the importance of focal length: ★★★★★
The smaller the projection ratio is, the better the image will be projected when you purchase it. The nearest one of your projection wall will be added. The closer the projection distance is, the more selective the TV cabinet is.
The focal length refers to the distance from the projector to the screen screen. The home projection must choose ultra-short focus, which is the projection TV, laser TV, etc. on the market. Because the shorter the focal length, the lower the depth requirement for your TV cabinet, this can Look at the parameter projection ratio as small as possible, international brands include the United States Polaroid, Japan's NEC, domestic brands have nuts, rice, etc., the shortest should be Polaroid, NEC, 50cm deep TV cabinet, you can project 180-inch large Picture; no matter whether the new house is renovated or the old house is upgraded, in the era of modern multimedia entertainment, the choice of home appliances is more and more diversified. For example, whether multimedia entertainment at home is equipped with TV or projection makes it difficult for many small partners to choose. In fact, it lists the main factors and makes a simple For comparison, you can make a wise choice soon:

If you have a budget of more than 15,000, you can consider the projection of high-brightness LED or laser light source. With a budget, you can fly in a wide sky, you can choose laser TV + screen + sound system + K song system....., I feel a bit off the mark, haha ;

First, the importance of brightness: ★ ★
Originally this is a very important parameter, but for the general public is just a reference, our people still believe that they are in the eye. The higher the true brightness, the better, the attention is real, because we do not have professional instrumentation, it is difficult to grasp.
Now many domestic manufacturers are full of mouths running trains, a lot of virtual standards, we can not buy a meter to buy a metering instrument. Another factor is that in fact, according to the standard of brightness testing, the short-generation projection of the new generation of products is simply not suitable for the previous measurement of brightness in the standard.
How to judge the brightness parameter indicator?
(1) Brightness is analyzed from the light source:
(1) Light bulb source. Brightness can be, but there are too many drawbacks in the home, eliminating technology, and now the home theater directly says NO.
(2) The projection of the LED light source can be marked with 3,500 lumens or more, and there is no moral bottom line. I think this kind of person can't stand it.
The true brightness of the LED is between 800-1000 lumens. This light source technology has been out for a long time. It is relatively mature, and the cold light source has no noise. The table 2000 to 3000 lumens is still understandable;
(3) Laser source. This is an emerging light source with high brightness, real brightness can reach 3000+ lumens, too bright for a long time, the eyes can not stand, so in other light sources are racking their brains to enhance the brightness, the laser is desperate to do low brightness, and It is power consumption, which is understood by the principle of conservation of energy. SONY's latest research report proves that the brightness is about 1000 lumens.
At present, lasers are plagued by cost. Almost all manufacturers only do two-color light in RGB, and one color is based on synthesis. This is too complicated to say...
(b) Brightness is selected from imaging technology:
At present, the mainstream projection imaging technology is nothing more than DLP and LCD, and its brightness is generally law:
Brightness: 3DLP>DLP≥3LCD>LCD
Second, the importance of color brightness: ★ ★ ★ ★ ★
At present, there are very few manufacturers that mark color brightness, but we can still make a judgment through the imaging technology used in projection:
Color brightness: 3DLP>3LCD≥DLP>LCD
This also means that the color of the projection screen is in one parameter, which refers to the brightness value tested when the three primary colors RGB are respectively projected, and the brightness values ​​of the R, G, and B color tests are added, if the brightness is white (the brightness parameter mentioned above is only the brightness of white light). The closer the better, the ideal state is equal.
Modern display devices have long since bid farewell to the "black and white era". Modern displays targeting the colorful world of color use only the "white light brightness" that characterizes the highest white picture display capability. It is obviously "outdated" and "insufficient." "Standard. The color brightness output (color brightness) standard provides the first time for the end user to provide scientific indicators for comparing the color display capabilities of different display devices.
The color brightness is equal to the sum of the average brightness of the three primary colors of RGB, and the brightness we generally recognize (white light brightness) is measured when a pure white picture is projected. We correspond to the RGB color standard, and the color harmony makes people feel very magical. The appearance of each color is generated by the RGB three primary colors by different hue saturation. When the three colors of red R, green G, and blue B overlap, white can be obtained.
Epson, Polaroid and other projection manufacturers to measure the brightness, the projector's color brightness CLO performance indicators need to be equal to the white light brightness, so the projector's color display is accurate and vivid, which is the same principle as the RGB three primary color superimposed white.
Third, the importance of contrast: ★ ★ ★ ★
My judgment method is to observe the black characters on white. The clearer the words are, the better. The manufacturer's albums can be referenced in the contrast digital reference. I hope that China's industry and commerce and consumer associations will make early moves, and manufacturers will be more self-disciplined...
The larger the contrast number, the better. The larger the display, the better the level and richness of the display color, just like the 12 color pen box and the 32 color pen box. It is precisely because our consumers are dying to recognize this parameter index, the parameters of the manufacturer's standard are getting higher and higher, and the kind of over 10,000 yuan will give up directly. The pedestrians know that the blow is big, of course, the project projection is not included, haha.
Fourth, the importance of projection screen: ★ ★ ★ ★ ★
Must be equipped with a professional projection screen, must be equipped with a professional projection screen, must be equipped with a professional projection screen, important things say three times. The most fearful of any projection is the uneven wall and the interference of ambient light. These two can only be solved by professional projection screen. Like the American Baoli I bought, people are selling with the projection and the curtain, and the light of the bedroom ceiling light. It will hardly affect the look and feel. It is also possible to turn on the lights, but I prefer to close the doors and windows and turn off the lights to find the cinema.
Fifth, the importance of projector life: ★ ★ ★
This will always have the right to speak only when it is actually used. Although it is important, it can only look at the parameters. I believe that it is impossible to participate in a few years. Anything has a time of use, and the projection is the same. The most important thing is because of the light source. At present, the life of LED and laser light source is very long, and it can reach 30,000-40,000 hours. Like my enthusiast fan, I watch it for 6 hours a day. Calculation, at least for 13 years, I really feel that I can live up to this time, haha.
In general, when you choose to purchase a projection, you must observe the color brightness and contrast, do not blindly parameter, you must do more homework and start again; high budget can choose laser projection, but I am more conservative, do not like to be small White rat, so I still choose LED light source projection, must be now what LED is LED, green, technology is also very mature; no budget or buy an LCD TV, but the screen is a little small.
Regardless of the renovation of new homes or the upgrade of old homes, in the era of modern multimedia entertainment, home appliances are becoming more and more diversified. For example, whether multimedia entertainment at home is equipped with TV or projection makes it difficult for many small partners to choose. In fact, the main factors are listed, and a simple comparison is made. And soon make a wise choice:
