Why do more and more people choose “laser TV”? After reading, I understand

(Last Updated On: December 24, 2022)

The year 2022 is coming to an end. Do you still like watching TV?

It has to be said that with the rapid development of science and technology, TV has gradually changed from cable TV to wireless TV/TV box, and the technology for making TV has also become more and more advanced, such as the “laser TV” that young people love nowadays.

Some insiders have said that traditional TV will be eliminated by laser TV in the near future. With the passage of time, the technology of laser TV has become increasingly mature. While the product performance has been improved, the production cost has also decreased. It is believed that in the near future, laser TV will become the first choice for consumers to purchase household display devices.

Whether traditional TV will be replaced by laser TV is unknown for the time being, but it is necessary to chat with everyone about the following things about laser TV.

Laser TV is a projector?

When it comes to laser TV, everyone will have a question. Is laser TV a projector? What is the difference between the two?

In fact, the difference between laser TV and projector lies in the type of bulb light source. To put it simply, laser TV uses R, G, and B wavelengths of continuous laser as the light source, which is different from most projectors that use xenon lamps or LED+color wheel to obtain R, G, and B colors.

This also determines that laser TV has advantages in color and service life. It does not have the problem of bulb service life, so it does not need to replace the bulb after one or two years of use. It can be comparable to TV in service life.

At the same time, different from projectors, the biggest feature of laser TV is that it can project a larger size picture at an ultra short distance. Most ordinary projectors use telephoto projection, with a projection ratio of more than 1.2:1. It takes 2-3 meters to project a large screen image. The projection ratio of laser TV is smaller, generally below 0.3:1. It can project a 100 inch large screen image only about 30 cm from the wall.

Laser TV display equipment refers to the display equipment that uses laser projection display technology and is equipped with a dedicated projection screen to display broadcast TV programs or Internet TV programs. The specification also specifies that the brightness unit of laser TV is “nit” rather than “lumen”. Nit is the unit of TV brightness, and lumen is the unit of projection brightness.

Equipped with a screen and using “nit” expression for brightness, it is directly related to the image quality of the product, which has also become a significant difference between “laser TV” and “projection”.

Does laser TV hurt your eyes?

When many people hear the word “laser”, they will feel that this kind of TV “hurts the eyes”. In fact, the highlight of laser TV is “more eye protection”!

From the perspective of imaging principle, the laser display adopts the diffuse reflection imaging mode. The light first reflects to the screen, and then enters the human eye. Therefore, the light received by the human eye is very soft, which is most suitable for the human eye. This is in fact consistent with the formation process of human vision, and the same principle as the human eye watching nature. For example, when flowers, clouds, sea and other images enter the eyes, it is the process that objects enter the eyes after reflecting sunlight.

In addition, the light source in the laser TV imaging process needs to be projected, reflected and transmitted for many times to filter the short wave blue light harmful to vision. The blue light wavelength is close to 460nm, which is more pure. The light that shows to the human eye has no harmful blue light, does not harm the eyes, and is naturally more conducive to protecting vision health.

From the perspective of working principle, laser TV is full pixel reflection when it works, reflecting images and colors onto the screen. There is no edge effect between pixels, and the transition is smooth. It can achieve full pixel light emission, rather than a small point light emission. In order to meet the brightness of the whole screen, the small point light emission makes the light emission points very bright and relatively dazzling. Full pixel lighting effectively reduces the light intensity per unit area, which is neither dazzling nor dazzling, and it is not easy to cause visual fatigue when watching for a long time.

Therefore, the advantages of laser TV eye protection are traceable.

How to choose laser TV?

Now all the major brands on the market are launching laser TVs. With the high price, the product quality is mixed. To select a truly cost-effective laser TV, you can refer to the following two suggestions:

1. Look at the brand – choose traditional projection manufacturers

When choosing a laser TV, the first thing to do is to choose the brands. It depends on which brands have been deeply involved in the projector field for many years, whether they have strong technical strength, and whether they constantly upgrade and improve the projector technology and image quality effect to pursue more authentic images.

We suggest that you choose some brands that focus on the projector industry and have been recognized by the market. Brands like Sony, Epson, BenQ, Hisense, Optoma, Wemax, etc., which we are familiar with, have a good guarantee in terms of technical strength and user reputation.

2. Look at the projection effect – choose a high-quality machine

The quality of the machine will also directly affect the viewing experience. We should pay more attention to the three indicators of brightness, color technology and intelligent system when selecting laser TVs.
The first is brightness. As mentioned earlier, the brightness of a real laser TV is expressed in “nit”.

Generally speaking, the brightness of laser TV needs at least 200 nits if you want to watch it under light conditions. To achieve a more ideal viewing experience, the above values need to be doubled.

Secondly, if you want to achieve the effect of a home theater, you must choose a laser TV with a high color gamut and strong color accurate reproduction ability. A wide color gamut means a more outstanding color experience.

Finally, a laser TV is also cheap at about 2000 USD. To meet the diversified life needs of modern families, whether the laser TV system is intelligent or not needs to be considered.


Looking at the moment, laser TV is developing rapidly and iteratively. With higher performance experience, better home integration, and lower cost, it is driving laser TV to enter more ordinary people’s homes and become an important part of a green, friendly, and high-tech high-quality lifestyle.
