Is a screenless TV a real innovation or a gimmick?

Since last year, the micro-smart projector industry has taken off, and many emerging brands and crowdfunding products have emerged. Its representative brands are mainly BenQ, nuts, extremely rice, and divine paintings. These miniature intelligent projection products are very small in size, and have built-in relatively powerful hardware configuration, integrated smart TV operating system, and with a rich external interface, can put 50-inch to 100-inch projection screen size. It can be said that apart from the screen, these smart projections and smart TVs are not much different. Therefore, in the industry, this is also called "non-screen TV."


With the fierce market competition, there is currently a considerable number of “non-screen TVs” in the price between 2000-3000 yuan, so it was exclaimed that the Terminator of TV came, and projection will replace TV! Is that really the case? The author believes that this is only a publicity gimmick, in order to fight the eye alarm.

First of all, the current micro-projection uses DLP technology, the projection brightness is limited, the ambient light is a bit stronger, the projection quality will drop sharply, and only in the night can we get a better projection effect. From the perspective of the projected area, due to the influence of the intensity of the projection light bulb, the projected area increases, and the brightness and the projection quality exhibit geometrical attenuation, and it is almost impossible to achieve an ideal audio-visual experience. High-definition television can achieve stable video display in all weather conditions, regardless of the environment.


To cool the newly released K2 series, for example, cool open 43K2 uses 43-inch LGD IPS hard screen, 19201080 resolution, screen brightness 240 nits, response time 9ms, refresh rate 120Hz, honeycomb matrix backlight, lamp beads evenly distributed in the TV On the back, the brightness of the lamp beads can be adjusted according to the brightness of the TV screen, and the heat can be evenly distributed to reduce the performance of light leakage. Cool open 50K2 uses a 50-inch Innolux 1920-1080 resolution screen, brightness 300 nits, corresponding time 9ms, refresh rate 120Hz. With such a display level, any "micro-investment" on the market cannot be the same.

Secondly, the projection is more constrained by space, not only requires a certain spatial projection distance, but also requires a higher degree of environment around the projection and viewing angle, and there must be no interference and obstacles between the projection and the screen. This is obviously less than watching TV easily. Cozy.


Third, stability is still the fatal weakness of microfinance. Micro-projection products are constrained by factors such as heat dissipation and endurance, and it is generally difficult to work continuously for more than two hours. This kind of endurance capability is very difficult even after reading a movie. The television can work for a dozen or even dozens of hours in a row. Stability does not affect the projection of a few streets. In addition, the micro-projection is obviously not as good as the service life of the TV.


Fourth, still limited by the size of the volume, poor sound quality has become a common problem in all non-screen TV products, and today's smart TV in the sound of the promotion is very rapid, sound quality direct "second kill" without screen TV.


Fifth, on the price, micro-investment also has no obvious advantage. Since the beginning of this year, major smart TV brands have launched new products and continuously reduced TV prices. The K2 series launched by Coocaust, with its “economics of living”, has a very high price/performance ratio. The price of configuration upgrade remains unchanged, which is more attractive to users.


As a 4K high-definition TV, cool open U50 price is only 2399 yuan, 55-inch U55C price is not to 300 yuan. Such TV pricing makes micro-investment products lose their competitiveness in an instant.

In short, there is no screen television, micro-investment is worth mentioning, although the hype is relatively hot, but as consumers must be an objective and rational analysis, we must not blindly and enthusiastically. With a price of 2,000 yuan, you can already buy a high-definition TV with high performance-to-price ratio and achieve a perfect digital audio-visual experience. If you are not a digital product enthusiast and fancier, it is recommended that you do not try to "innovate" the "rat". Before the micro-projection technology has a big breakthrough, it is still more reliable to choose high-definition television.
