Advantages and disadvantages of laser tv or LCD TV in laser tv.

1. Is laser tv better or LCD TV better?

1, image quality comparison

The image quality of LCD TV is generally recognized as good. Take TCL75Q 10 as an example. Its QLED quantum dot technology has an ultra-high color gamut of 157% and1000 billion colors. The color purity is increased by 58.3% and the color lasts for 6000 hours. In this picture quality, the pores of stars and desert particles can be seen clearly, which is very realistic and delicate. Not only that, it also adopts Dolby vision technology, which greatly improves the brightness, contrast and color of TV, further strengthens the visual experience and gives people a more realistic feeling.

2. Visibility comparison

Laser tv is subject to the shortcomings of diffuse reflection imaging and is easily influenced by ambient light. The brightness is low, it turns white when the light is bright, and it is easy to see the picture paste during the day, not to mention the details of the film and television, which is difficult to meet the needs of watching movies. On the other hand, the viewing angle of laser tv is only about 20 degrees, beyond which you can hardly see clearly, while LCD TV can reach 70 degrees, which is quite different.

3. Life comparison

Relevant research shows that the life of laser light source is about 15000 hours, while the life of LCD module is over 30000 hours, which means that the life of laser tv is only half that of LCD TV. Converted into a home TV, it is equivalent to a family buying two laser TVs to match an LCD TV, and the cost of family expenditure has also increased, which is not worth the candle.

4. Blue light contrast

The LCD TV has a clear picture, and the skin color of the imaged characters will be more natural, and the eyes will not be tired. Taking TCL75Q 10 TV as an example, its eye protection function is a highlight. MEMC omni-directional motion anti-shake technology is adopted to make the moving picture stable, clear and without tailing, watch the ball more smoothly, see the fighting scene more clearly and the picture will not flicker. Secondly, in terms of lighting, technologies such as mixed dimming and natural light are adopted, and the light source is not dazzling. More importantly, it also has the function of preventing blue light, so even if children and the elderly face the TV screen for a long time, they don't have to worry about eye fatigue.

Second, the advantages and disadvantages of laser tv

Advantages of laser tv:

1, ultrashort focus

Laser tv is also a kind of projection in essence, but the screen size of laser tv is larger than the general projection, and the projection ratio is smaller. Even if the equipment is placed on the wall, it can project a picture of 80- 100 inch. At present, the mainstream laser tv projection size is generally around 150 inch.

2, the radiation is small

Laser tv's image captures the light reflected by the host computer in laser tv from the laser tv screen, which is consistent with the principle that human eyes see everything in the world. Compared with LCD TV, it does little harm to human eyes and will not feel tired even if it is watched for a long time.

3. Long service life

Generally, after the projector is used for a period of time, there will be a problem of insufficient brightness. At this point, the user needs to buy and replace the projection bulb. Because laser tv uses laser light source, not only the brightness is higher than that of ordinary projection, but also the brightness decays slowly, and the use time of tens of thousands of hours is enough to meet the needs of families.

4, intelligent

At present, laser tv basically has its own intelligent system, which supports intelligent voice function, which reduces the learning cost to a certain extent, and is also very practical for families with old people and children.

Laser tv's shortcomings:

The disadvantage of laser tv is that the resolution is less than 4K. Due to technical reasons, the projection equipment used in laser tv can't show movies with 4K resolution, and it can only reach the picture quality level of 1080P, so it is a great harm to consumers who pursue picture quality. In addition, compared with LCD TV, the price in laser tv is 1-2 times higher, which is unbearable for ordinary families.
