In daily life, there are many ways to enhance happiness: sometimes after a thorough cleaning, a clean and tidy room; sometimes a small object that is not expensive but full of experience; sometimes a potted plant that is not usually noticed grows small shoots. Different people have different feelings, but in general, household items have the most obvious improvement in the happiness of daily life, because good household products can make the home warmer and more comfortable, and they want to stay at home to experience life in their leisure time.
For us office workers, the happiest moment of the day is to come home at night, take a beautiful shower, make a cup of tea, and then dive into the soft quilt, open the projection brush drama to watch movies, the quiet environment plus the immersion of the big screen, a small luck flowing in the heart, the pressure of the backlog of work during the day, at this moment to get unprecedented relief.
Bedroom + projection, can be called the ultimate version of the home happy partner. Projectors do not need to be fixed like televisions, and they will take up a lot of space. Advances in projection technology have made it possible for today's projectors to be as portable as mug size. Very friendly for the bedroom scene, you can directly cast it on the white wall or ceiling, and then lie down and watch TV, and enjoy the beauty that technology brings to life.
But the premise of all this is to choose a good projector, bad products certainly can not bring excellent experience, and many friends just do not know how to projector, Lingying will come to tell you in detail:
In general, it is sufficient for consumers to buy a projector that focuses mainly on portability and imaging results.
Portable is very easy to choose, beautiful and small, easy to carry, you can choose according to personal preferences. Important is the imaging effect, and there are several key parameters that need special attention.
In terms of expansion, there are mainly brightness, resolution, and projection ratio.
Brightness determines whether you can see the picture clearly during the day, lumens as the brightness indicator of the projector, when purchasing, you must see clearly what the "ANSI lumens" value is. In general, indoors with better lighting, corresponding to the projector 1000-1500 ANSI lumens are more suitable.
After the brightness is selected, it is the resolution. The higher the resolution, the clearer the quality of the projection and the better the viewing experience. Everyone will see the resolution, but pay attention to distinguishing between standard resolutions and compatible resolutions.
The standard resolution is the resolution of the final output of the projector, which is the clearest picture effect you can see. Compatible resolution is the resolution that the projector supports decoding, for example, a projector standard resolution is 1080P, compatible resolution 2K, 4K, that is to say, it can decode 2K, 4K movies, but the resolution of the broadcast is still 1080P.
Therefore, the compatible resolution is useless to blow no matter how crazy, and the final picture clarity still depends on the standard resolution, the higher the better!
Once the brightness and resolution are determined, the projection ratio remains, which determines how large you can see in a limited area.
Projection ratio refers to the ratio of projection distance to the width of the picture, here we need to explain, we usually call the length of the projection screen as the width, width as the height, so do not misunderstand.
The projection ratio of ordinary projectors is usually between 1.5-1.9, and when the projection ratio is less than 1, we usually call it a short-throw lens, and when the projection ratio is less than 0.6, we usually call it an ultra-short-throw lens. For example, if your bedroom has a bed-to-wall distance of three meters and you want to see a 100-inch frame, the projector's throw ratio is recommended to be below 1.35:1.
The last sentence summarizes: buy a projector to see the degree of portability, two main imaging effects, including brightness, resolution, projection ratio.
