Laser TV

What is Laser TV?

There are three kinds of  traditional television: LCD TV, Plasma TV and Rear-projection TV. The looks is quite similar, but technology is different. Now Plasma TV and Rear-projection TV is going to end, just some brand insist to launch some new models, like Sharp select the Plasma way, and Philips launched Laser backlight 8000 series LCD TV.

Another road is Home Theater Projector, there are so many brands, such as Epson, Sony, NEC, BenQ, Viewsonic, Optoma, Vivitek and JmGo, etc… But common home theater projector is not Laser tv.

So what is Laser Television?

Laser Source.  Of course, be laser tv, the source of light should be Laser! For the traditional projector, the source is LED lamp, the life of lamp is about 4000~5000 hours,  Only after 2 or 3 years you should replace the lamp, it is not a Laser TV. If select Laser source, the life is extend to 30000 hours! Can be used for 10 years. The brightness of screen of laser source is more than common LED source.

Big Screen. Be a future technology, Laser TV should fulfill the trend of television revolution: more bigger screen. 55~65 inches is the main steam of LCD TV until now. How much if the screen bigger than 100 inches of LCD TV ?Maybe over 100K USD. But for the laser TV, the price should below 10K USD, only 1/10 of the LCD TV.

So what is the secret of Laser TV, how can them get such performance with low cost? They are ultra short throw projector with laser source!

What is Ultra Short Throw Projector?

Projection ratio of the ordinary projector, usually between 1.5-1.9. When the ratio of the project is less than 1, it is called a short throw porjector, and when the ratio of the projection ratio reaches 0.6, it is called the ultra short throw projector! At fact, most of the UST (ultra short throw) projector, the actually projection ratio below 0.5, even reach to 0.2.

Can you image projection ratio reaches 0.6, or even below it? For 100 inches screen, the length of screen is about 2m, so the distance between screen and projector is only 1m or even less.

Why need Laser Light Source?

Laser is the highest intensity of artificial light. The science and technology industry has made great efforts to make the laser beam used in projection imaging.
Compared to other light source, the laser imaging efficiency is high, the optical performance is stable, color is more pure, brightness is more uniform.

Traditional projector can only show the 30% color of the nature which people can identify, resulting in another 70% of the color can not be intuitive to feel. Solid LED or laser is an ideal light source for digital imaging, laser film screening performance more than 90% of human color recognition, laser film projection function to the viewer to restore a more perfect colorful real horizon, to better meet the needs of film broadcast on demand.

Traditional projector in use after a period of time with light decays rapidly and the image becomes dark yellow (such as luminance attenuation, color saturation and contrast decreased), at the cinema the high requirements of use occasions, even if the lamp is still glowing, also had to the replacement of lighting, resulting in high use cost. Laser projector is laser as the light source, the service life can reach more than 30000 hours. The decline process is slow, making the output quality to maintain long-term high brightness, color saturation, contrast, color image is always bright as new.

What is the Problem of Laser Technology?

At present, the bottleneck of laser technology industrialization is that the cost of light source is high, the industrial chain collaboration is difficult, the lack of resources and the comprehensive environmental facilities and industrial investment is not enough. Laser technology can solve the current technical problems, and the market is still need time. At present, some industries are still struggling with the laser display standards, more product placement attempt is the trend.

As we all know, Epson is the KING of projectors. Every projector with Epson logo, means better image quality and high stability. Epson LS100 also has such characteristic.Most laser TVs use TI DLP solution, for the cost issue and want much more small size. DLP need rolling color wheel to get different colors. Sometimes besides RGB rolling wheel, a Yellow color will put into the wheel to get more image brightness, or just white light passthrough. 3LCD has not such features, it has 100% RGB color and very sharp contrast of color. Without rainbow and color overflow, eye watching is more comfortable and products are more comfortable. At most times, 3LCD solution need more cost.
