Applied Nanotech, in conjunction with six Japanese display component manufacturers has completed its proof of concept of a high resolution, full color, 25-inch diagonal carbon nanotube prototype TV, that is brighter than the ones in stores today.
A demonstration video of the proof of concept in operation is available to view on the Company's
. The video clip clearly shows that, the video image of the 25-inch TV screen does not suffer from the "ghost images", that can be observed in large LCD and plasma TVs as a tail of the image moving across the screen.
As expected, the image and its characteristics are similar to the cathode ray tube, since CNT (Carbon Nanotube) TVs are a flat and thin extension of the CRT technology.
In conventional CRT TVs, an electron gun fires electrons at a phosphor-coated glass divided into pinpoints to create images. The electrons, however, need to disperse in a large vacuum, which is why TV tubes are so large and bulky.
In so-called field emission display (FED) TVs, electrons get filtered into an array of thousands of tips only a few nanometers wide, which then deliver electrons to illuminate the screen. As a result, these TVs can be thin, like LCDs or plasmas.
The proof of concept has a 25-inch diagonal glass substrate with a 22-inch diagonal viewing area, and
operates at a voltage that is fully compatible with low cost CMOS drivers. The distance between
subpixels, which is a little larger than 0.5mm, was selected so that the printing techniques utilized are compatible with 60-inch diagonal Advanced TV format and 80-inch diagonal High Definition TV.
"This proof of concept is a critical achievement in that the processes, including printing-like processes,used in creating the display will allow manufacturers to dramatically reduce the capital investmentneeded to produce CNT TVs," said Dr. Zvi Yaniv, Chief Executive Officer of Applied Nanotech.
As the industry moves from ATV format to HDTV format (720 x 1280 lines), the 25-inch diagonal
concept proves that ANI CNT technology is fully capable of HDTV format on 80-inch diagonal TVs
(defined by the Japanese National Broadcasting Corporation NHK as the main target for consumer
"Although we are obviously not television manufacturers, I am extremely proud of our team's
accomplishment of perfecting the processes necessary for the production of CNT TVs,"said Marc Eller,
Chief Executive Officer of Nano-Proprietary, Inc. "This greatly improves the chances of getting a
partner to initiate pilot production."
Toshiba, Samsung, Canon and other consumer electronics companies are experimenting to see if carbon nanotubes, diamond dust and other materials could blend the superior picture quality of conventional cathode ray tube, or CRT, televisions with the slimmer designs of LCD and plasma displays.
Canon and Toshiba have cooperated since 1999 on these type of screens--which the two call surface conduction electron emitter displays, or SEDs. Both companies plan to start selling SED TVs in 2006.
