Laser TV vs Regular TV
The most important parameters for a screen are color, brightness, and life span. What are the advantages and disadvantages of laser TV compared with ordinary TV on these several parameters?
Colour performance
As the technology matures, laser TV with RBG three-color laser is also beginning to appear. At the recent CES, Hisense announced a three-color laser TV, while Nut Project unveiled a three-color laser TV, Nut U2Pro, last week. The three-color laser brings a purer light source, and the color performance of the picture has been greatly improved.
Screen brightness
The measurement unit of laser TV brightness is usually lumens, lumens are also divided into light source lumens and screen lumens (ANSI lumens), and screen lumens is usually the brightness of laser TV mobile phone picture. Now some high-end laser TV such as just released NUT U2PRO can do 3500ANSI screen lumen, with Fister-Fresnel screen, the brightness is quite bright, even when the lights are turned off at night, people will feel dazzling.
Of course, LCD TV is brighter, but the light goes directly into the human eye, which is more harmful, so they usually have a decent viewing distance. In contrast, laser TV will be more eye protection, because it is diffuse reflection, being closing will not be too dazzling, but more cinema-like immersion.
The service life
Laser TV uses laser light source, life can generally reach 20 thousand hours, compared to the projector using light bulb light source, this life is quite long. However, LCD TV's backlight can usually reach a life of 50, 000 hours.
The reason is that the laser light source is small in size, high in temperature and easy to aging. And LCD TV light source is relatively scattered, orderly arrangement, brightness uniformity, good heat dissipation, so compared to laser, LCD TV life is much higher. Of course, with the progress of technology, the life of laser TV is gradually improving.
Write in the last
Perhaps a lot of people think that laser TV is a very short focus projector, calling it laser TV is just a marketing gimmick. What should it be called laser TV or ultra short focus projector, in fact, that depends on your definition of TV. However it is undeniable that laser TV has become a new category different from the projector.
With the maturity of three-color laser TV technology, now the laser TV is not only larger in size. Although in brightness and life it is still not as good as LCD TV, but the color performance has begun to gradually surpass the LCD TV. It is believed that with the improvement of public awareness and acceptance, as well as the more mature technology of laser TV, the price of laser TV will be further explored in the future. Laser TV may be a new direction for the big screen TV in the future.
