The sense of TV existence is getting weaker and weaker. Everyone from the elderly to children has a mobile phone. TV is purely an active atmosphere. In the past two years, laser TV has become popular and popular among young people.
So what is laser TV? Is it easy to use? Today, I will show you a real experience of laser TV.
What is Laser TV?
To put it simply, laser TV is an Ultra Short Throw Projector+Screen.
However, the projector of laser TV is different from the traditional projector mainly in these two aspects:
- First, the laser TV uses an ultra short throw projector, which has a small projection, while the traditional projector is a medium long throw projector, which has a large projection ratio.
- Second, the projection light source of laser TV is laser, while the traditional projector is LED lamp.
Therefore, the laser TV can be regarded as an advanced version of the projector. Its principle is that the light source provides brightness, and then the light source is processed by the imaging chip, and the light signal is converted into a picture, which is finally projected onto the screen by the lens.
Pros of Laser TV
1. Large Screen Size
The reason why people like laser TV is that the screen is large, generally 100 inches, 120 inches and 150 inches. The super large picture looks very cool.
The size of traditional LCD TV is 70~80 inches, and the maximum size is 100 inches. Otherwise, it will be very expensive.
In addition, if the traditional projector wants to project a 100 inch picture, the projection distance must be very far. It requires a certain space, which is difficult for an ordinary living room to reach.
Laser TV does not have this kind of trouble. It can be placed on the TV cabinet and can be projected at close range.
2. Great Watching Experience
With a large TV screen, you can enjoy an immersive cinema experience. You can create a feeling of cinema at home. You don’t have to go to the cinema.
And although the laser TV is a projection, it is placed on the front TV cabinet, so people will not walk around to interfere with the viewing experience.
3. Long Life Cycle
The service life of laser TV is closely related to the light source. The light source used by the laser TV is the laser light source. The temperature is relatively low during operation, so the aging speed is relatively slow, so the service life is relatively long, generally more than 25000 hrs.
4. Eye protection
The image of the laser TV comes from the light reflected by the screen from the host. It is the same as the principle that people use their eyes to see everything in the world. Compared with the LCD TV, it is less harmful to the eyes, and the eyes will not be tired when facing the screen for a long time.
Moreover, some laser TVs have the function of automatic screen rest. When you are too close to the screen, it will automatically stop the screen and recover the image after leaving to protect your eyes.
5. Save Power
For the same size, the energy consumption of laser TV is at least half lower than that of ordinary LCD TV. If it is used for many years, the energy consumption saved is also considerable.
Cons of Laser TV
The price of Laser TV on the market is generally more than 1500 USD. If the size is larger, the quality is higher, and the price is more than 5000 USD, which is very expensive.
LCD TVs are relatively cheap, generally 500 USD (below 65 inches), 1000 USD (60~75 inches) for better ones, and 1500 USD for more than 80 inches.
2. Low brightness and poor contrast
Laser TV has low brightness and poor contrast because of its imaging principle.
Low brightness means that the laser TV is affected by the ambient brightness and has poor light resistance. If the indoor light is sufficient, you will not be able to see the screen clearly.
Contrast is the color of the picture. If the contrast is not good, the bright parts of the picture will become dark, and the dark parts will become bright. The picture quality is poor.
3. High installation difficulty
In fact, the laser TV machine is very easy to install, mainly because it is difficult to install the screen, which mainly includes the black grid screen and Fresnel screen.
The former is a soft screen, which can be curled, but the anti light effect is not good. The latter is a hard screen, which cannot be curled, but has better anti light effect.
It should be noted that the curtain of large size may not be able to enter the elevator of the community during installation and handling. It needs to be lifted by a crane, which requires additional installation and handling costs.
There is also a kind of screen for laser TV, which is assembled by the manufacturer in advance and does not need to be assembled on site. This screen is generally called a hard screen. The hard screen is mainly difficult to transport and transport into the home, and the on-site installation is relatively simple.
To tell the truth, when we buy TV, what we value most is the watching experience, and whether the watching experience is good or not mainly depends on two aspects: picture size and picture quality.
Each kind of thing has good or bad points, which should be selected according to needs, and should be combined with the watching conditions of your own house.
Therefore, when you buy a TV, you can consider these aspects and buy a TV that is really suitable for your family.
