Plasma TV, flat panel televisions, high definition television, when these next-generation digital television is still
approached our lives, scientists in the development of the laser TV has achieved significant progress.
Laser TV is the use of diode-pumped solid-state laser materials, red, green, blue three-wavelength continuous-wave laser
light source, as a color laser TV is controlled by trichromatic laser television signals scanned images. Laser TV and
traditional TV has the following characteristics:
(1) Laser TV color distinctive, high brightness, the screen size is flexible, bright image on the surface of various
materials, can be expected to, or even a curved surface. The system also can be adapted to all television standards,
currently using the PAL system, numerical control systems, and SECAM VGA or high-definition television.
(2) Laser TV is the most powerful competitors in the TV market in the 21st century, it is higher than such as plasma TV
technology is simple, colorful; Laser TV is brighter than bright, large-screen LCD TV perspective direction.
(3) The laser is a 100% monochromatic laser TV red, green and blue light modulation, the color effect is very satisfactory.
Life expectancy of up to 10 hours of high temperature aging test up to 10,000 hours at room temperature in order to calculate
the room temperature lifetime, so it is the product of a long life and high reliability.
(4) Laser TV can develop into a special big-screen television, film and projector integrated multi-function products.
Laser TV
The LDT, Germany, Samsung, Sony Corporation, Japan and Japan s Mitsubishi Corporation Laser TV in Japan Sony Laser TV
developed "direct scan line scan, the LDT, Germany, Samsung has used the" spot scan "mode. Mitsubishi Corporation Japan has
recently launched its three-color laser light source DLP rear projection rear-projection TV, support for the latest
international standard of color space, eliminating the color wheel, a single DMD chip, with good color performance of the
laser DLP rear projection TV DLP with the previous rear projection projector biggest difference is to cancel the light bulb
as a light source, color separation wheel, steering the three semiconductor lasers primary colors of light transmitted
through the optical fiber to the DMD chip, due to multiple reflections in the fiber, reducing the laser interference fringes.
Meanwhile, in order to achieve the image to restore, Mitsubishi also developed the image modulation NCM (Natural Color
Matrix), the video signal and color signal separation model of brightness, the color signal into 12 independent tone control
to get the best color reproduction color reproduction capability of the laser projector has been recognized by the
International Electrotechnical Commission (IEC), the color space can achieve a wide color gamut, color space, than the
currently used radio and television signals, an increase of 1.8 times. Mitsubishi Corporation of Japan produced a new
generation of color laser light high-definition television, the image quality can be more than the film quality, the product
is expected to be listed at the end of next year.
