Chinese home display devices have been pursuing large size, when black and white television popular, or even have a special magnifying glass placed in front of the television, used to enlarge the image of the television.Nowadays this way of grounding has disappeared, LCD TV more than 50 inches Of the screen to meet the basic needs of consumers.But the pursuit of size, the desire of consumers will not be stagnant.
Large screen has always been a dream
Back in the LCD TV shine before, in fact, appeared on the market a large screen display device that is rear projection TV rear projection TV is actually a projector using the back projection of a large screen device because the projector is cast For the light is too sensitive, and the rear projection can solve this problem.But rear projection TV due to the need for a larger projection space, so the product is very thick, coupled with its light source is not durable, so gradually out of the market.
As early as 2006, the global number of rear projection TVs will be reduced by 15% to 4.4 million units from 5.2 million units in 2005. Almost no rear projection TVs have been seen since 2010. The size advantage of rear projection TVs Is obvious, but the same obvious shortcomings, so many large-scale investment in rear projection television companies have suffered losses, while the choice of liquid crystal display business is pocketed profitable.
Rear projection TV exit, the market has no home large screen devices, plasma and LCD devices can achieve 100 inches, but such products are high price, easily hundreds of thousands of price not the average consumer can get. So it can be said that the demand for oversized screens has been frozen for many years.
So the market really no home large screen program it? Laser TV recently gave the answer, laser TV attention is also increasing. Here we talk about why the laser TV so fire.
Light upgrade to new hope
Rear projection with the traditional light bulb, thousands of hours of brightness was significantly reduced. This is not acceptable to consumers. The emergence of laser light source, a complete solution to this problem. 20,000 hours of life, even 8 hours a day Also can be used for several years.And the laser light source to achieve the same brightness and more energy-saving than the traditional light bulb, for the average consumer, this is electricity, but also for the positive support for environmental protection.
Laser light source also solves the problem of brightness bulb light source requires high heat dissipation, so the need for greater body space.But the family often do not have much space, and the laser light source transmitter is small, so in achieving the highlight at the same time, Laser TV is more compact.
One of the advantages of laser light source is the color. At present, the laser light source to use more monochromatic laser, which is the blue laser with yellow fluorescent pink wheel technology. Hisense and polar rice also introduced two-color laser light projection, the use of blue laser At the same time into the red laser, which can significantly enhance the color gamut of the screen. The effect of comparable quantum dot or OLED display products.
In the end the laser light source is not in danger of blinding lights, and home use adds safety, and many laser TVs have unique eye protection features that stop working when there are any objects in front of the lens, Eyes hurt.
LCD large bottle price bottleneck
Laser TV can achieve large screen, LCD devices can also achieve large screen, above we have said that 100-inch LCD devices are expensive, in fact, in addition to the price, the 100-inch LCD devices, there are many other problems. The first is hundred Inch LCD device screen is large, high brightness, long time to watch very hurt eyes. LCD backlight design, light through liquid crystal molecules become a direction, this light is harmful to the human eye.
Second, large LCD TVs, whether it is very inconvenient to install or move, it may even be difficult to enter your living room from your home, before the news reported that because of the 100-inch LCD TV is too large, the user can only choose to use the lifting of the way The windows are shipped in.
Another 100-inch LCD TV weight of 40 kg or so, the ordinary wall simply can not support such a weight, can only choose to put it on the load-bearing wall above, this greatly limits the living room furniture placed way for the user Very inconvenient.
The last 100-inch LCD equipment, energy consumption is very high, although the small size of the LCD device with LED backlight is very energy-saving, but enlarged to 100 inches later, in order to ensure the screen brightness, LED light source energy consumption rose sharply while large-size LCD TV Thickness and borders can not be too thin, its integrated space may not be low.
Laser TV is composed of a reflective ultra-short focal projection host with a laser light source and a 100-inch or more light-resistant screen (some brands support its own brand of anti-light curtain option.) Projection hosts are usually powered by a smart operating system that enables similar intelligence TV online big-screen viewing, games and other applications.We think that laser TV is a solution that integrates projection technology, anti-light screen, sound system and intelligent system, and can not be equated with the projector simply.
This is the concept of the laser TV we are given. In fact, from a technical point of view, the laser TV and the rear projection products have similarities, the use of reflection projection, but rear projection mirror design big, while located in the fuselage Of the outside; and the reflected laser light more compact, while located in the fuselage inside the rear projector projector needs to be located in the back of the screen, as long as the laser TV can be placed in front of the screen, it can be said that the laser TV is rear projection TV Evolutionary upgrade version.
At the same time there is no smart rear projection TV system, and now the use of laser-based ultra-short-focus reflective laser technology and laser light source technology also incorporates the advantages of intelligent systems for laser TV can watch a variety of online content to solve the content source Problem.At the same time the laser TV is also equipped with anti-light curtain, which makes the laser TV screen brighter, can adapt to more scenes.
Here, we also gradually understand that laser TV is so concerned about, in fact, the essence or large size advantage.This is a frozen demand for more than 10 years, once the world's rear projection TV shipments reached the level of millions of units, The current laser TV shipments are still in its infancy.As the concept of laser TV become clearer and more reasonable prices, I believe the market share of high-end laser TVs will gradually increase.
Of course, the rapid development of laser TV, but also face many problems.Currently, traditional projection, home appliances and the Internet and other enterprises have entered this area.However, the development of the laser TV industry is still in its infancy, from concept, technology, publicity to the system and many other There is no complete standard appears, I believe that the rapid development of standards will contribute to the development of laser TV.
