Five Changes in Multi-Dimensional Look at the Evolution of Laser Television for Four Years

Since the beginning of the development of laser television, laser light sources have been the main focus. Laser light source is a kind of cold light source, with characteristics of high brightness, longevity, and good color performance. In general, the lifetime of the laser light source of the laser television can reach about 20,000 to 30,000 hours, which is enough for the average family. Compared with traditional light sources, laser light sources have advantages. However, the laser light source also has a certain cost, which is why at the beginning of the development of laser television, we can only see blue monochromatic laser light source products on the market, rather than two-color or three-color laser light sources.

The monochromatic laser television mainly uses a blue laser generator and a color wheel with a phosphor to realize the effect of simulating a three-color light source. Due to the lack of green and red laser generators, the cost is lower, and the final price of the product can also be improved. Recognized by consumers. The two-color laser television mainly uses a red and blue laser generator with a phosphor-added color wheel to achieve the effect of simulating three colors. Both of these have not adopted green laser light sources, mainly because the cost of the green laser light source is relatively high and it is difficult for consumers to accept it.

Expensive green laser light source

With the gradual development and improvement of the market, and the decline in the price of red laser generators, we ushered in consumer-grade two-color laser light source laser television in 2017. In the demonstration, its brightness performance and color performance have been improved. This also allows us to look forward to the emergence of consumer-grade tricolor laser televisions in the market.

Resolution is a basic parameter of display products. Since the online video content has been hot, the production level of film sources has been increasing. Therefore, having a high-resolution display device is still necessary for individual home users because it can slow down the elimination of products.

At the beginning of the development of laser television, we saw a large number of products with 1920×1080 resolution in the market. However, LCD TVs achieved the popularity of 1080P resolution in 2010, and that year was also known as the first year of popularization of 1080P. Therefore, this resolution standard is only the entry-level level of LCD TVs in the same period. At that time, there were still viewing regrets for some large movies on the Internet, and it was difficult to meet the actual needs of users.

Visual contrast between 1080P resolution and 4K resolution

After four years of continuous development, the market has already reached a resolution of 4K or 4096 × 2160 resolution laser television products, which is already ultra-high resolution. Such a clear picture quality allows users to see more refined image details on the same size picture. In addition, since the laser television is a large-screen display device, only when the high resolution is satisfied, it can be guaranteed that the picture quality will not decrease after outputting a large-size picture.

Good friend of laser television: anti-light screen

During these four years, laser television also experienced the development stage of scratch-resistant screens from scratch. The light curtain is a kind of screen product with a special coating. The principle of its realization of light resistance is mainly through the incident light from the bottom of the screen to enter the human eye, and reflect the Ambient Light in other directions to ensure the projection in the screen. The picture is clear and bright.

From the definition of laser television, we can see that laser television is a combination. This combination not only includes ultra-short-focus projectors that use laser light sources, but also includes a 100-inch or more light-resistant screen. This shows that the laser television host and the anti-light screen are good friends. Separating from each other, it is bound to degrade the picture quality.

The current situation is that laser televisions have been equipped with a light-resistant screen as a standard at the time of sale, and users can choose to purchase them separately. A 100-inch light-resistant screen, the market price is basically more than 5,000 yuan. For laser televisions, the light curtain is a must-have accessory, and this concept has now basically been recognized by the industry.

Accurate electric focus is convenient

Laser TV lens section

Since the laser television uses an ultra-short-focus lens, it is basically a fixed-focus lens and cannot achieve the effect of adjusting the focal length. If you want to adjust the picture to a clear state, it can only be done by manual or electric focus. This kind of focusing method can not only achieve a clear picture, but also ensure that the screen size of the projector is not adjusted to be too large. For laser televisions with a fixed-size light-resistant screen, this solution serves two purposes.

Manual focus lever for laser television

In the past, the manual focusing process of laser televisions mainly achieved the focusing operation through a manual focus ring or a manual focus lever. After four years of development, we can also achieve the electric focusing operation of the laser television on the remote control, which saves time and effort.

Home installation diagram is peace of mind

The main reason why people buy laser televisions is because the screen size is large enough. However, the larger the screen size, the more effort it takes to move the product and the more tedious the installation process. According to previous LCD TV installation experience, more than 50-inch LCD products are more difficult to move. And the hard LCD screen cannot fold and roll up.

In order to solve the installation of laser TVs, manufacturers have gradually introduced on-site installation services, which can reduce the user's troubles, which is a good way. However, what should we do after the installation workers have gone? Is it possible for the user to easily correct the entire picture?

Bidirectional trapezoidal correction function

The traditional laser television picture correction is mainly based on trapezoidal correction, and the finer ones may add two-way adjustment, and the adjustment range can also achieve about 40 degrees. With people’s increasing attention to laser television, we have also seen continuous improvement in product production. There has been a free-range correction in the four corners. In this way, the user can easily adjust the picture at home and apply the entire picture to Anti-light screen corners, complete the adjustment.

After four years of development, laser TVs have gone from monochromatic laser sources to two-color laser sources, 1080P resolution to 4K resolution, no anti-optical screens to standard anti-light screens, manual focusing to electro-focusing and picture adjustments. Trapezoid correction to two-way trapezoidal correction and even the four corners of the five transformations. These five changes mean that the gradual self-change of the laser television, also represents the market demand for product promotion.

Finale for the year 2017 Laser TV Hengping Review

Compared with the market, Zhongguancun Online formally launched the first full-screen laser TV review from the perspective of professional media. In the Hengping review, we measured a total of 8 popular laser TVs, and the evaluation results were very good, because almost every model has its own bright spots. Whether starting from the price of a product or from the point of view of practical applications, a new generation of laser television products has a remarkable place.

Judging from the above results, in fact, laser television has also been significantly improved in other aspects, such as style, sound quality, color performance, etc., which can be said to be the benign development of such products. After four years of development, we have seen the advantages of laser television and LCD TV contending. Perhaps in a few years, laser television will be able to occupy half of the big-screen display market, and even more. It took only four years for laser television to realize the transformation of monochromatic light sources into two-color light sources. This shows that the potential of this product is huge, and the introduction of laser television into the daily lives of ordinary consumers may not be far away.
