TV or will die? Ultra short throw projection occupy the future living room

What is an ultra-short home projector? As the name implies, home projection using ultra-short focus technology. This type of projector can generally project one-hundred-inch large screens within a distance of one meter, which can achieve wall projection. From the screen size, it easily defeated the LCD TV, which is also an inherent advantage of the projector. TVs are subject to the cost of liquid crystal panels, and the cost of making large-size LCD TVs is too high. Therefore, it is rare to see oversize LCD TVs.


In the past, most of the projectors that we were able to reach were commercial and educational projections used in classrooms and conference rooms. These traditional projectors have certain requirements for space, that is, they project 100-inch and 120-inch screens. It takes a certain projection distance. There is a certain gap between the projectors of different brands and different models. However, for these high-definition home projectors tested by the author, most 120-inch screen projections require more than 4 meters. . However, for small-sized users in cities, the lack of space has become the only constraint.

å•¥ is ultra-short focus technology


In fact, the emergence of ultra-short-focus projection technology has just changed this situation. A lot of my friends are not really clear about the specific definition of a short focal projector. The projector has a projection ratio, which is the ratio of the projection distance to the length of the bottom side of the projection image. Generally speaking, if the projection ratio is less than 1, we can call it a short focal projector. Of course, the smaller the value is, the more effective the short-focus projection is. The projection ratio can be simply divided into three categories: the first category, which has a lens projection ratio of less than 0.4, is now a reflection-type ultra-short-focus projector; the second category, a product with a projection ratio between 0.4 and 0.7, can Abbreviated as ultrashort focus projectors; the third category is ordinary short focus products with lens throw ratios between 0.65 and 1.



Some of the current ultra-short-focus home projectors can project a large 100-inch screen at a distance of about 0.5 meters, such as a meta projection P10. In this case, at home only need a 100-inch screen and an ultra-short-throw projector is OK, and has completely replaced the TV to become the overlord in the living room.
