Sharp develops super high-def screen for future TV
Baku, May 20 (AZERTAC). Japan`s Sharp has developed an 85-inch LCD (liquid crystal display) panel with resolution equivalent to 16 times that of today`s HDTV panels. The screen, which is only a prototype, was developed for Super Hi-Vision, a next-generation television system currently under development in Japan. Japan`s Sharp has developed an 85-inch LCD (liquid crystal display) panel with resolution equivalent to 16 times that of today`s HDTV panels. The screen, which is only a prototype, was developed for Super Hi-Vision, a next-generation television system currently under development in Japan.
At 7,680 pixels by 4,320 pixels, Super Hi-Vision images will have four times as much detail horizontally and vertically than the best of today`s HDTV images. The system is being developed by Japan`s public broadcaster, NHK (Nippon Hoso Kyokai), and demonstrations of early prototypes have shown a very detailed image with beautiful colors. The images are so good, the viewer can feel immersed in a scene in a way not possible with current 3D TV technology. The first public trials of Super Hi-Vision are due to start around 2020 and the development of the LCD screen is the latest in a number of steps towards that goal.
Because of the large amount of detail in each Super Hi-Vision image -- each frame is equivalent to a 33-megapixel picture -- highly complex cameras, mixing and switching systems, and recorders and transmission equipment need to be made to handle the huge bandwidth of the video image. Recent years have seen a number of developments towards smaller, lighter and cheaper Super Hi-Vision prototypes. Earlier this year, JVC unveiled a Super Hi-Vision projector that is less than half the size and a quarter the weight of previous devices. The projector is still fairly large, heavy and expensive, but its development serves as a further indication that work towards the 2020 goal is progressing. Development of Super Hi-Vision began in 1995, just as analog HDTV broadcasting was beginning to take off in Japan. NHK, which is one of the few broadcasting companies to heavily invest in R&D, began work on HDTV in 1964 and was the first broadcaster in the world to launch regular HD broadcasting. It`s hoping to repeat that with Super Hi-Vision in the next decade.
