Reasons to buy the projector should be only one, is the huge screen can bring immersive feeling , whether you are watching movies or playing games, this feeling is the television can not provide.
With a simple setup, you can create a visual experience at home that is almost the same as in a movie theater. In a private space, whether it is you, a loved one, or about three or five friends, this feeling is more relaxed and comfortable than in a movie theater.

The more common projectors on the market illuminate the light source on the original image, and then project it on the wall or curtain through the lens. Among them, the more traditional light source is projected with a halogen lamp or a mercury lamp as a light source, which is somewhat similar to the halogen lamp on a car.
The basic figure above shows how it works, though the bulb is life , but the general projectors have reached 4,000 hours and above life, so use a few years is more than enough. In addition, as the bulb requires a certain warm-up and wait to reach a certain brightness, so in turn the projector on and off all the time need to wait a little before they can start slideshow . I believe that all the friends who have used projection to make PPT lectures in the class have experience.
In addition to the conventional lamp of a projector, there is used an LED or laser as a light source of the projector start commercial, and long life, color accuracy, high contrast, and other characteristics are their advantages.
The above picture is the working principle of a simple laser projector. RGB (Red, Green, Blue) three-color laser clearance reflection is projected on the screen through the lens to achieve the effect of displaying the picture. However, many manufacturers currently produce such projection types Use two blues and subdivide one of the blues into red and green with the lens.
TV vs. Projector
Talked about so much, is not the focus , really focus on why buy a projector. The characteristics of TV are long life, clear picture quality, and brightness is not affected by external brightness. Optional projection is also simple. This is just like why you should go to the cinema. The projection can easily display 100-inch, 120-inch or even higher screen sizes. Compared to TVs, 80-inch TVs, aside from the price, it is a headache to think about how to move it home.
Things you need to know to buy a projector
1. Brand
Brands are very important, good brands naturally have good projections, and later quality assurance services are also very good
Recommended: Sony, BenQ, ViewSonic, Epson, Optoma, JVC, JmGo, etc.
2. Throw ratio and resolution
This depends on what you intended to be placed in the room space projected from the projection screen to the projection distance and you want to project a ratio between the screen size . The data for different projections is different. Here it is recommended to determine how big the screen size you want to be, and then choose the projection that can meet your requirements according to the distance of your room.
In terms of resolution, if you just look at the movie in general, 1080P is basically enough to play Xbox. 720P is not recommended here because it is really a bit stretched under the large screen size. In addition, if you pursue a high-quality picture, it is completely Can be projected on 4K, that effect lever.\
3. Lumen / Lumen ( the physical unit describing luminous flux-from Baidu Encyclopedia ) and contrast
Lumen can be understood as brightness here, and the brightness of home projection is sometimes not high. According to the actual situation of the person, if you just turn off the light and watch a movie at night, the lumen only needs to be normal, but if you want to It is recommended to use a projection with a larger lumen if it is used during the day even when the projector is turned on.
Of course, the higher the contrast, the better, the color will be more gorgeous under high contrast, and the details will be more clear .
4. Noise and others
Personally think that the size of the noise is also very important here. During the use of the projection, heat will be generated and the fan needs to be cooled. However, if the fan sound is too loud and affects the overall viewing experience, it is really very stifling. In Before purchasing, please note whether the noise was clearly identified size, or be judged according to those who have purchased a comment .
5. The darker the viewing effect, the better
The brightness of the projection is limited, so if you watch it in the daytime or under strong light, even if the lumen is high, or the contrast is high, the effect will not catch up with the TV, so the first thing to determine is the time you want to watch the video. , but if you are very busy during the day, they want to see the movie and so on, we should first pay attention to not be able to create a good environment for you to watch the projector , otherwise, or select TV now.
6. The projection screen is very important
Please consider a good curtain before starting the projector. Compared with the wall, the curtain will really bring a very different effect. In addition, the curtain will take up a certain space. If you need to hang the roof and need some For the installation of hands-on ability, friends must consider these factors in advance. If it is a stent-type curtain, consider whether there is enough space in the home to place the curtain.
7. Audio output
I found that access to information, some of projection will be with speaker equipment inside, but is very basic, no sound at all, some of the more expensive projector will still be a good speaker effect, but for higher quality Video and audio, and speakers are inevitable , so partners need to consider these issues at the point of purchase.
6. Price
In fact, the market price is really good projection did not imagine so high, and sometimes have an advantage compared with television, but the price considerations must not only stay on the projector single price, you have to consider the need for post-wire audio The price of equipment, curtains, etc. , budget is very important.
