The downturn of the color TV industry in 2017 was most intuitively reflected in the decline in sales. According to data from Aowei Cloud Network, the retail volume of domestic color TVs in the first half of 2017 decreased by 7.3% year-on-year, and the net profit rate fell below 1%. Whether it is OLED TVs or quantum dot TVs, the growth rate has been declining, but laser TVs have attracted the attention of the market and sales have gradually increased. Peng Xiandong, general manager of China Consumer Electronics Co., Ltd., told the media that due to the increase in panel prices, the laser TV market in 2017 will grow at a rapid rate of 200%, especially in the 80-inch and above market, and laser TV sales will account for more than 60%. How can laser television "secondarily kill" OLED screens and quantum dot screen televisions? What are its advantages and disadvantages?
The advantages of laser television
1. Big screen has immersion
The big screen is indeed the most intuitive advantage of laser television. Laser TVs are mostly over 100 inches, and 120-inch and 150-inch products are also everywhere. Although the sales volume of TVs was decreasing in 2017, large-screen TVs came to the fore. As of the end of May 2017, the share of large-size TVs with a size of 55 inches and above was maintained at approximately 33%, compared with a growth rate of 52% in January last year. It can be seen that the large screen more and more satisfies the needs of users. Laser TV is born with the advantage of a big screen, and therefore it will receive more attention from users who plan to purchase large-screen TVs. Since the screen is large and IMAX's stereo technology is used, there is a strong sense of immersion when watching a movie. This is one of the reasons that users love it.
2. Rich HD color gamut
Compared to other televisions, laser television uses a high-processing optical engine and high-resolution lens, using 4K resolution, and its color gamut can theoretically reach a human visual gamut range of more than 90%. Therefore, it looks like the colors will be more vivid and the level will be more clear. Compared with other types of TVs, the picture quality will be better.
3. The price advantage
Hundred-inch laser TVs generally cost more than 10,000 yuan, which may seem expensive. However, compared to traditional LCD TVs, prices actually have a lot of advantages. Due to the problems of LCD TVs' own materials, it is difficult to realize large screens. The maximum size of most screens is about 7, 80 inches, and if the screen size of LCD TVs is 100 inches or more, the price will be several hundred thousand dollars, which can be hundreds of inches compared to 1,200,000 yuan. For television, the price difference is not a little bit worse.
Laser TV disadvantage
1. Product installation difficulties
Laser TV uses a laser projector + a special metal screen. It is similar to a projector in its installation method. However, it is more convenient than a projector. It can be mounted on a TV cabinet without lifting. However, since the projected image must match the screen 100% to achieve a good viewing effect, the most troublesome problem is that the projection focus of the product at the time of installation is too bad, or the effect is very bad. Shadow ghosting, or the screen is trapezoidal.
2. Not moveable
Due to the problem of picture mobilization, the already placed and adjusted projection television cannot be moved any more. Even if it is only slightly moved or moved after it is touched, the focus must be re-adjusted and the normal focus and position must be restored again. It is very troublesome again.
3 laser light source eye damage
Laser light source is a strong light source, although the light projected onto the screen is actually softer and more invisible than the light of the LCD TV, but looking directly at the light source is too bright and it will irritate the eye, especially if there is a child in the home. When eye development is not yet complete, direct stimulation of the eyes by a bright light source may affect the child's vision and cause serious injury.
In any case, laser television has broken the product structure and viewing experience of traditional television for so many years. As a large-screen television product, it is undoubtedly a more cost-effective television for families living in large-sized houses. The choice, as to whether it can spike other types of televisions, regardless of the user, there must be a market, spike, or wait to observe it.
Splitter: To divide the input signal equally among the different sets; At the same time, these televisions are isolated from each other. Usually there are :2 distribution (divided in two), 3 distribution, etc. Cable TV also has a distributor, which is different from a distributor. The branching device transfers some of the energy to the next stage. Branch devices are often used in cable television networks
