Most people think that the bigger the TV picture is, the better, but the most suitable TV is the metaphysics. Starting from 9-inch black-and-white TV, there are various arguments. 12-inch, 18-inch, 21-inch, and 27-inch TVs have become the best size for TVs in the CRT era. The estimated number of children after 00 has little impression. In the era of flat-panel TVs, the early 40-inch screens were big screens. Now that mainstream TVs in the market are basically 50-inch, they can buy sixty-seven inches for a little extra money. Beyond this level, there is a rapid rise in prices, ranging from RMB 30,000 to 100,000.
30,000 yuan to buy Taiwan 80-inch TV, compared to less than 10,000 yuan will be able to buy Taiwan projection, projection 100-inch screen, obviously the projector is more attractive. The general publicity of laser projection television can replace the TV and use the projection TV to watch TV directly in the living room. 100-inch TV to 100,000, and now million projector can do it, do not rush to buy buy? Stop it first.
The ultra-short-focus projector does solve the problem of the troublesome installation of the conventional projector. As long as the TV cabinet is not too small, it is very easy to project images of more than 100 inches. However, there is a major difference between projection and television. The use of laser projection to replace television applications is currently somewhat difficult.
The TV screen is the light source behind the screen (or the panel itself), and the projector's light is projected from the light source through the lens onto the wall or curtain, and can be seen by the user through reflection. So turning off the TV you see is a black screen, and closing the projector you see is a white curtain or wall, both of which have very different environmental requirements.
Traditional projectors need to have a better shading environment to watch video content, because the brightness level expressed by the projector is actually a contrast between different strong and weak rays formed on the white screen. If ambient light hits the curtain, the shadows on the projected screen will be seriously affected. The same light shines on the TV screen, and the black material reflects light much weaker than the screen. So watching TV can turn on the lights, and the cinema must be dark after it starts.
In order to solve the impact of ambient light, laser projection TVs are mostly equipped with a special gray screen. The gray of the gray screen itself can inhibit the scattering of ambient light better than white, and these gray screens use special materials that can directionally reflect the projector's light and reduce ambient light interference. Although it looks good, the problem is that the price of this screen is not cheap, so the price of laser projection TV sets is also very high.
In the bright living room, even with the much higher price of the laser projection kit with curtain, I feel that the effect is not perfect, and the brightness, contrast and gradation of the screen are obviously insufficient. The price of millet laser projection TV 9999 does not include a special screen. As an ultra-short-throw projector, it is indeed very cost-effective, but when used directly as a TV, you will be disappointed.
Laser light source and ultra-short focus lens have obvious advantages on the projector. Laser light sources can provide higher color saturation, better luminous efficiency, and significantly improved light source life; ultra-short-focus lenses can reduce the difficulty of installing and arranging equipment, but they cannot directly overthrow traditional TVs. They are not competitive. Relations, but complement each other.
The projector in the prior art, the best home application environment is still the occasion to block the ambient light - pull on the blinds, turn off the lights, and only the large screen in front of you, allowing you to exclude interference immersed in the movie scene. Regardless of the size of the screen, the TV is better used in the normal light and family to watch variety shows or TV shows, chat, snacking or moving around more easily. The applications of the two seem to overlap, but the requirements and application environment are different. Just like sports cars and cars in the automobile field, there are excellent products that can be run by people. However, one must control one to be comfortable without competition.
The reason why the ultra-short-focus laser projector was hung on the name of a TV, I think more is to attract users attention. When TVs are seriously homogenized, manufacturers have to find new technologies and new selling points. Although various advanced technologies have been applied, the products are indeed different from the past, but if you look at the promotional materials and save money, and you simply want to use this thing instead of TV, users may be disappointed.
