In the area of ​​ultra-large-size TVs, the cost of LCD or LED TVs is very high and the prices are quite expensive. The Japanese manufacturer Sony's 100-inch LCD TV is priced at 500,000 yuan, and the LG's latest OLED TV is 77 inches at a price of nearly 200,000 yuan. So on a large-sized display, projection becomes a low-cost solution. In the past two years, major manufacturers have introduced laser projections.
What exactly is the symbol of the rise of laser television, the fourth generation of television technology?
Laser projection TV is still a relatively unfamiliar term for the public. To be precise, laser projection TV is also a kind of projection device. It is a device for short-distance large-size picture placement based on ultra-short-focus projection technology and laser light source technology.
As a new product following black-and-white television, color television, and high-definition television, laser television is seen as a sign of the rise of fourth-generation television technology. The reason why laser television dares to call “television†is because of its ultra-short focus feature, which can deliver 100-inch or even larger images in a short distance. Laser light source can provide higher brightness and better color performance. Moreover, laser televisions generally have their own audio systems to ensure the unification of the user's audiovisual experience.
One, long time watching is not easy to fatigue
In fact, it is not accidental that manufacturers compete for laser television. Due to the difference in technology with LCD TVs, laser TVs are not only easy to grow in size, but also have outstanding advantages such as health, energy saving, and low cost. Laser TV is based on the principle of diffuse reflection. Its radiation and power consumption are much lower than those of LCD TVs. It is not easy to watch fatigue.
Second, the stability is very good
There is also the stability of the laser. Users who have used projection for a long time should have such an experience, that is, after the long-term use, the conventional light bulb will have problems such as brightness decay and fading. If you replace it, the cost is too high. Sticking to use and influencing the viewing experience is simply chicken ribs. The laser light source is stable in performance and will not suffer from the above problems when used for a long time, which not only saves trouble but also saves costs.
Third, the screen performance is more clear
At the same time, the screens used by laser televisions seem to be like LCD TVs. In fact, there are big differences. Laser TV panels use cold screens, which are screens that do not require power. In addition to the glass substrate, a multilayer film was added to reduce the diffuse reflection of light and make the picture appear clearer.
Fourth, long-term use will not produce color failure
In addition, the color saturation of laser televisions is high. We are familiar with CRT TVs, with a rich color palette. By the LED TV era, color performance has declined. This is an indisputable fact. The imaging principle of laser television determines the high degree of consistency of color performance. Even if it is used for a long time, there will be no color fading phenomenon. Unlike the use of CRT TVs for a long time, there will be a decline in color.
