Laser Projector

Nowadays, we consumers are surrounded by all kinds of edgy products and new trends. If there is a big witness for this whole consuming development, TV definitely has a say in this. Starting with the ancient black-and-white television, we’ve come to the ERA of laser TV, in the foreseeable future.
Laser TV, in a nutshell, is an ultra-short-throw projector using laser light source, which is equipped with anti-light curtain. Commonly used in living rooms, barely influenced by the lighting environment compared with traditional LCD and DLP projectors.

For Laser TV, it adopts the laser as its own light source by name, which can provide higher color saturation and better luminous efficiency. At the same time, it does not have the problem of service life, so it does not need to change the bulb after one or two years of using. It can be said that laser TV is the more advanced product than ordinary projector, which is the development direction in the future. Compared with projector, laser televisions use less energy than projector, and it has a longer service life and does not require the frequent replacement of expensive projection bulbs. Laser projection requires a shorter focal length than light bulb projection, it can project a screen of 100 inches even placed only 50 cm to the wall.

First of all, the difference between laser projectors and ordinary projectors as we call them is in the service life of the light source. The service life of the laser light source can be about 25,000 hours, and the service life can be calculated by 8 hours per day for at least 10 years. While the service life of ordinary projector basically only has 5,000 hours or so, if calculate by 8 hour per day, resulting in less than 2 years. Relatively speaking, the laser projector does not need to replace the light bulb. Secondly, the laser projector reflects the light of the laser machine directly into people’s eyes, so people will see the clear picture. However, the traditional projection requires a certain distance. In order to make people feel more comfortable to watch the screen, these projectors adopt the principle of diffuse reflection to avoid direct reflection of strong light. Therefore, their performance of anti-ambient light is relatively weak. Therefore, compared with ordinary projectors, laser projectors has higher contrast ratio and better image clarity.

In fact, there are brands like Optoma, BenQ, and Epson, already selling ultra-short throw projectors, whose claimed service life is 5,000 hours. However, the brightness and contrast performance would decay after 2,000-3,000 hours of using, which does exist, may not be often spoken of.

Some say laser TV is just a form of advanced projectors. Well, when it comes to laser projector, it might just refer to the machine itself. For laser TV, the projection screen, the speaker, and other attached accessories are also included, which indicates the application difference between laser TV and laser projector.  

Light source of Laser TV, inevitably, would decay over a long period of using. 20,000 hours in theory, 5 times longer than other light sources, almost the same as the service life for the LCD TV. The color gamut of the laser light source should be much wider than that of the bulb with the same price. However, for the monochrome laser, if the manufacturer hasn’t adjusted it properly, there will be a bluish situation when playing the white scene, which most customers won’t even be aware of. For those who have high requirements on the color accuracy, you need to pay attention to that. For the moment, laser TV, with 100 inches screen, seems a great choice.
