What is the concept of laser television
What is laser television? Although there are already many laser television products on the market, the concept of laser TVs for each brand is different. Therefore, the products are not only different in shape, but also the definition of laser television for each brand is different. Is it possible to use a reflective ultra-short focal optical system and configure the laser source to be a laser television? This issue is worth discussing.
Only after understanding the basic definition of laser television, we can discuss the problem in the title: What is high-end laser television? We think that laser television is a solution that combines projection technology, anti-light screen, sound system and intelligent system. The product cannot be simply equated with the projector.
Why do you say this? Because laser TVs have a much wider customer base than traditional projectors. The application environment for laser TVs is also more complicated. Laser TVs will not always be used in dark environments. It will not be seen that they will be equipped with separate advanced speakers. How can we meet the basic application requirements of users? Obviously, laser televisions must meet three major requirements. Elements: First, laser televisions are resistant to ambient light. Second, laser televisions must have content output capabilities (intellectual systems or television signal receivers). Finally, laser televisions must provide sound output capabilities.
Although such a definition cannot be said to be absolutely free of errors, the generalization of laser television is fairly comprehensive. After the concept is approved, we can discuss the solutions that high-end laser televisions should be configured with. Here we will talk about what hardware configuration high-end laser television should have.
Core Foundation: Brightness and System
Although laser television cannot simply be considered a projector, its core indicator is still brightness. Although ordinary consumers watch the laser television to configure the anti-light curtain, this effect can be brighter. However, the light curtain is not a panacea, and the final image brightness of the screen is still based on the brightness of the projection host.
As a high-end laser TV, the brightness naturally can not be sloppy, at present although many laser TV nominal brightness reaches the level of 4500 lumens, but actually tested ANSI brightness is still less than 3,000 lumens, its average level at 2300 ANSI lumens. The author believes that the measured brightness of laser TVs in the future should reach a level of 3000 ANSI lumens, so as to satisfy the complex home environment.
Here I also want to talk about the system. There are many laser televisions that do not have a configuration system. Although some enthusiast users prefer to use Blu-ray players, laser televisions face ordinary home users, and their product integration requirements are even higher. With the smart TV already deeply rooted in people's minds, the laser television configuration system has become a general trend. So I think high-end laser television must be configured system.
Color performance two-color laser
In addition, the color performance of laser televisions has to give power, and the basis is still the light source. At present, many laser televisions are monochromatic laser products, that is, blue laser as the core, with yellow fluorescent pink wheels. This light source mode is cheap, but the final color effect is not good, because there is no native red and green in this system.
In theory, the three-color laser works best, but due to the high price of the red and green laser generators and the complex structure of the three-color lasers, the cost has not been reduced, only to appear on high-end movie projectors. Ordinary users It is impossible to accept the price of a three-color laser light source projector. So there is no laser television with three-color lasers.
So bi-color laser has become the first choice for high-end laser television. The so-called two-color laser is actually in the blue + fluorescent pink wheel mode to add the red laser, so this system will have a native red. With such a light source system, laser television can naturally tune out better picture quality performance.
Two-color lasers have significantly improved brightness and red color performance compared to the first-generation blue laser display technology. Compared with blue laser, two-color laser has increased red laser light source and will effectively improve the display effect including red and yellow. The appearance of two-color laser televisions has already been present, and Hisense and Miji have already released two-color laser television products. The future high-end laser televisions should all develop in this direction.
4K upgrade trend
The penetration rate of 4K TVs in China has exceeded 50%, but at present, there are few products that realize 4K resolution in laser TVs. China is entering the ultra-clear era, and various ultra-clear resources are constantly emerging, in the case of TVs that have been basically 4K. Obviously, laser television cannot stay in the 1080P era.
Why is the speed of laser TV 4K upgrading slow? This is because the resolution of the projector has always been a short board, in other areas have already realized when 1080P is an entry configuration, the projector is still regarded as a treasure 1024 × 768, not to mention Said 4K resolution. However, unlike laser televisions, they face no longer the traditional user groups of projectors. They have to compete with LCD TVs. In order to occupy a large screen market, it is necessary to increase the resolution.
4K resolution is not difficult for the laser television, the core index is whether the upstream chip manufacturers can provide the right chip, the current 4K laser TV chip size is larger, which led to the 4K laser TV is also relatively large, In the future, the upstream core chip provider for laser TVs will provide smaller 4K chips to promote the development of 4K laser TVs.
The advent of laser television has made it possible for families to achieve large screens. Many people think that laser TV is still a traditional projector product. In fact, this view is still a bit one-sided. Although laser television is based on projection technology, its future is to compete with LCD screens. If you want to pass a curve, you must have excellent quality. The author believes that high-end laser televisions need to be full articles on brightness and systems. In addition, they must actively expand and upgrade their color and resolution so as to further enhance the competitiveness of laser televisions.
