As cutting-edge high-tech continues to refresh the eye, from the previous rear-projection TVs and plasma TVs to today's LCD, QLED, OLED technology, etc., people are also arguing about the development direction of future display technology. Some people think that OLED is the future trend and is a special existence beyond traditional LED. Some people think that the cost of OLED is too high, it is difficult to popularize the public, and it may not become the mainstream in the future. In the past two years, the display technology industry has been turbulent, and more and more companies have begun to switch to laser TVs. In the future, there is a new choice in the direction of display technology. Is laser TV really promising? Will it threaten the survival of LCD TVs?
What is a laser TV?
Laser TV is actually not a new concept. It had a basic prototype in the 1990s. In 2006, Mitsubishi had launched a 40-inch laser TV prototype, but because the technology was not mature at that time, it did not get a better one. Promotion.
Laser TV is divided into two parts. One is the machine itself, which is a reflective ultra-short throw projector. The reason why it is called laser TV is because there is a laser light source inside the machine, which is a laser. The other part is the projection screen. The laser TV must use a specific screen, not just a white wall or a soft screen.
The core part of a laser TV is of course the laser. The laser can emit light of a certain wavelength and color. The three primary colors of red, green and blue are generated through the crystal or light guide material in front of the laser, and then the laser is focused and combined into the color we expect to display. .
What is the difference between a laser TV and a projector?
After understanding the principle of laser TV, some people can't sit still. Isn't this just a projector? Will it become a laser TV after packaging? In fact, this sentence itself is wrong. The projector itself may only contain a body, and it may not even need a screen. However, the laser TV itself is composed of a host speaker and a special screen, and both are in form. There is a big difference.
From the light source point of view, the projector is the light source provided by the bulb, and the light emitted by the bulb is projected onto the curtain or white wall, and then reflected to our eyes, so that we can see the real picture. The laser TV is a short-focus laser light source. Compared with traditional light bulbs, this light source has a higher color gamut and a longer lifespan. When matched with a light-resistant screen, the picture fidelity and brightness will be better than those of a projector, and there is no problem of changing the bulb.
What are the benefits of laser TV?
Advantage 1: Flexible size
In terms of size, laser TVs are more flexible than ordinary LCD TVs. The maximum size of laser TVs on the market is more than 100 inches, and can project a 100-inch screen around 55cm. The principle is basically the same as that of projection, and it can be free according to the size of the living room. Adjust the size, so for different living room environments, the laser TV fits better.
Advantage 2: Ultra-low power consumption
Perhaps most people don't think that the LCD TV in the home consumes high energy. Compared with the big power consumers such as rice cookers and air conditioners, it is indeed not considered high energy consumption. However, due to the small screen size of the home LCD TV, the energy consumption is not high. If the LCD TV achieves a 100-inch screen, the energy consumption is quite exaggerated. A 98-inch LCD TV from Philips has a power of 500W, while a 50-inch LCD TV has a power of only about 100W.
Although the size of the laser TV can reach more than 100 inches, its energy consumption is quite low. The power consumption of a 100-inch laser TV is only equivalent to the level of a 40-inch LCD TV. The laser TV does achieve large size and low energy consumption.
Advantage three: high cost performance
Although the price of laser TVs on the market is about 10,000 yuan, the size can easily reach 120 inches or even 150 inches. This size can be put on an LCD TV at a price of 500,000 to 600,000 yuan, which ordinary consumers will not. Buying such high-end products, laser TVs of the same large size seem to be particularly cost-effective, and the price is more affordable and easier for most people to accept.
Will laser TV replace LCD TV?
As a new type of TV, laser TV inevitably has to be compared with traditional LCD TV. As two completely different TV display technologies, laser TV and traditional TV must have their own advantages and disadvantages. The color TV industry will have a major technological reshuffle every ten years. Ten years ago, the CRT TV market was completely eliminated, and manufacturers began to pursue plasma TVs. Today, ten years later, will laser TVs replace LCD TVs?
Whether it can surpass LCD TVs and become the mainstream must be analyzed from many aspects. The most important and direct one is sales, and sales are closely related to consumer concepts, prices, and the products themselves.
From the perspective of consumption concept, no matter how the TV technology evolves, the size is always inseparable from the "large" development, and it has become a continuous publicity point for TV manufacturers in recent years. Nowadays, when consumers buy TVs, TVs below 40 inches will hardly be considered, and TVs above 65 inches will be sought after by more people. The emergence of laser TVs suddenly pulled the TV size to more than one hundred inches, bringing a stronger visual impact and being more likely to be favored by consumers.
From the perspective of price, ordinary households spend more on TVs at around 3,000 yuan. At this price, there are many choices for LCD TVs, but for laser TVs, you can’t buy anything at all. A set of products. Although laser TVs are more cost-effective than large-size LCD TVs, it still costs about 10,000 yuan. From the current price, there is no possibility of popularization or even replacement of LCD TVs.
In addition, the core indicator of laser TV is brightness, which is a flaw that laser TV has had since its birth. At present, many laser TVs on the market have the problem of false brightness. The nominal brightness can reach 4500 lumens, but in fact, the ANSI brightness is only about 2500 lumens. This brightness is almost not enough for the living room with very good lighting. of. A certain brightness standard must be met to adapt to the complex living room environment.
Judging from the above indicators, although the laser TV is overtaking on the screen size, due to the price and brightness of the flaws, it still cannot be popularized in a short time. The only way to reduce the price is to reduce the price to a level that consumers can adapt, and Only by formulating a qualified and unified brightness standard can it be popularized.
Summary: Laser TV represents the future
Laser TV is known as the fourth generation TV. Compared with traditional LCD TV, it has absolute advantages in power consumption and size. Therefore, many manufacturers are committed to taking laser TV as the future development direction. Its potential is immeasurable. I believe After laser TVs are better regulated in terms of prices and standards in the future, they can gain a firm foothold in the family and seize the huge market of 100-inch screens.
