Analysis and Application of Laser TV
2016年11月2日 時事ニュースSince the advent of television, with the development and improvement of technology, many families have become one of the essential items. At present, the mainstream of the LCD TV has dominated our living room for more than 20 years, and now the LCD TV prices are very favorable, but the screen size already reached a bottleneck. Although the market appeared more than 100-inch large-screen LCD TV, but the price is not expensive to the average family can afford to play. How to meet the majority of people on the pursuit of a larger screen, the display industry has become a barrier to break.

But the home has a large screen does not account for space, I believe many people will think of home projectors, mainly because of their own problems difficult to make home projector popularity, into more people’s living room. First of all, ordinary home projector brightness is limited, during the day on the living room to watch the picture is really difficult to see, followed by the projection distance problem, because the projector projection screen size and projection distance is directly proportional to the living room of many people in the home is limited , So want to see a larger screen or some difficult, and finally the problem of light source life, the traditional projector bulb light source is generally only a few thousand hours of life, brightness decay fast, need to replace the lamp on a regular basis to improve the maintenance costs.
Laser TV two years in the display circle is a novel and hot words, and blue laser pointer TV is also a solution to the family to watch the big screen one of the best programs. Now most of the laser TV lenses using reflective ultra-short focal length design, generally only need tens of centimeters of distance can achieve about 100 inches of the screen. At the same time, laser TV laser light source in brightness and service life compared to the traditional home projector has been greatly improved, which is one of its greatest strengths.

First of all, what with everyone about science and technology laser TV. Laser TV consists of two parts, the first is the laser projector itself, the reason is called laser TV, because the projector uses a laser light source, so the essence of laser TV is a reflective ultra-short focal projection laser technology Light projector; the other part is the projection screen, because the laser TV must meet the specific screen can be, not just a white wall or soft screen can be.
Currently on the market most of the laser TV using DLP imaging technology, as long as a small number of Japanese products in the use of LCD technology. The main reason for this phenomenon is DLP digital technology is used, the image contrast, gray scale (256-1024 level), color (2563-10243 kinds), image signal noise ratio, picture quality and stability, outstanding performance, Second, the current mainstream laser TV are using reflective ultra-short focal projection technology, and DLP imaging principle is also reflective technology, the current technical point of view on the advantages of DLP should be significantly greater than the LCD. However, 50mw laser pointer TV why the use of reflective ultra-short focus lens? Because this lens can be achieved in a very short distance cast a hundred inches of screen effect, that is close to the wall from the laser TV on the place, and do not need to consider the traditional projector as the projection distance Problem, but also do not have to worry about moving around in the living room to the screen. Said so many DLP technology does not mean that LCD technology is not good, but at this stage of the DLP laser technology than the LCD technology advantage is more obvious. These two technologies has been the projection market, the two main camps, have their own advantages and disadvantages, the Japanese manufacturers have made use of LCD technology, laser TV, I believe that with the development of technology, such laser television will appear in our eyes.

A laser TV is good or bad for consumers, mainly to see how it works, as a projector channel evaluation editor, evaluation of the laser light source projector also has a number of units, the laser projector in the brightness of the Performance has been very good, but the color test is always flawed. Today, give you a simple reason to talk about one of them. In theory, RGB 20000mw laser pointer light source color is the best, but the price of this program is too high. So the industry began to use blue laser semiconductor with fluorescent wheel way to achieve the RGB three primary colors, this "simplified" program, the accuracy of the color in fact has been a problem. First of all, because the current blue laser light wavelength slightly shorter 2-6 nano-effects, the screen appears the case of color purple. After the use of blue laser + blue, green, red phosphor mode to improve this problem, but the blue is not the case still appears.
Followed by the blue laser mixed fluorescent pink color wheel mode fox color gamut value is not high, although the theoretical value of the laser light source color gamut is very high. But that refers to the performance of RGB laser light source, for this monochrome laser light source, the color gamut is the numerical value and the gap is still great theoretical. Color gamut is not high led to the level of the screen color is not enough, a lot of color distinction or difficult to show. Take red, for example, a variety of red a lot of the projector are difficult to distinguish, but the human eye in nature is able to distinguish this difference. Overall, the laser TV in the screen color performance is still not quite satisfactory, and hope that the major manufacturers can come up with more and better solutions, whether it is to use two-color light source or the real RGB light source, or Adjust the color wheel range of color range worth mentioning as soon as possible to repair this shortcoming of 100mw laser pointer TV is the future direction of the development of this industry.

Today, many people like to see 3D movies, if you can at home watching 3D movies, then it is a lot of people’s dreams. In fact, the 3D movie is good or bad largely depends on the brightness of the screen, because 3D technology, passive 3D glasses will now greatly reduce the brightness of the film. The brightness is an important part of the picture quality is good or bad. There is no brightness of the screen contrast to get out of light and shade, the 3D film, the brightness of the glasses to bring the attenuation of the real impact of the screen greatly reduced. Therefore, if you want to watch 3D movies at home, the projector brightness is not enough, the impact is quite large. With the application of laser light source and the emergence of laser television, projection brightness control finally have a way. Laser light source has a bright, energy saving, color and long life characteristics. These features make the laser light source in the home market has a natural advantage. Especially the characteristics of long life, to ensure that the brightness of the laser light source decay is not so fast.

And the laser light source energy efficiency is also better, the laser light source can now reach 10 lumens / watt, so the energy consumption, the output of the same brightness, laser light source is more power. At present, some light source manufacturers and projector manufacturers have also given 30000 hours of warranty time, if the brightness of the laser light source in 30,000 hours to 70% attenuation below the visible 30mw laser pointer light source technology has been more mature, from brightness to life, Home projection market, laser TV has an overall advantage. Therefore, want to feel at home more shocking 3D film, laser TV is a good choice. I believe that with the technology continues to mature, 3D video screen brightness of the problem will be laser TV fundamentally solve. The current cost of laser light source is continuing to decline, laser TV pricing will gradually be more acceptable.
Said the subject of so many laser TV, then for everyone to talk about it another part of the curtain. As I mentioned earlier, 3000mw laser pointer TV is composed of two parts, both of which are indispensable, because laser TV needs to overcome the ambient light, highlighting a more bright picture. This screen uses a special optical jagged structure, above the sawtooth structure for the black light blocking absorber layer, below the special coating structure, allows true feedback of the projected image, the resulting high-contrast images. Such a curtain has the advantage of resisting ambient light and increasing contrast. In fact, this principle is not difficult to understand, the structure and material on the screen more complex, but the essence of the principle is in fact oblique laser TV obliquely below the light refraction to the observer’s eyes. White wall is the effect of diffuse reflection, that is, following the light above the white wall, the light to launch around, so the brightness of the screen will be reduced, and specially designed anti-light curtain is the focus of light projection viewers The brightness of the screen is higher. Anti-light curtain according to the principle of anti-light, there is the use of physical structure to achieve anti-light effect, but also the use of optical coating to achieve anti-light.

Buy laser TV at the same time, must be with a special anti-light curtain, and this curtain does have the effect, which I evaluate the process of laser TV on the deep experience, even the evaluation room lights open, the screen is still clear to the force, Color is no particular big change. On the other hand, for the purchase of laser television, the cost of the curtain or can afford to play, or buy home is difficult to experience the advantages of 10000mw laser pointer TV. Anti-light curtain of the scientific and technological content is still a lot of good anti-light curtain can provide good anti-light effect, while increasing the contrast, with good visual performance, etc., need to study a special physical structure or optical coating. Do not covet cheap to buy some cheap imitations, as the effect will be greatly reduced. So the best choice and laser TV specifically configured anti-light curtain products.
