This Copytele has a Technology License Agreement with an Indian TV maker Videocon:
Technology License Agreement with Videocon Industries Limited
On November 2, 2007, we entered into a Technology License Agreement (the "License Agreement") with Videocon. Under the License Agreement, we provide Videocon with a non-transferable, worldwide license of our technology for thin, flat, low voltage phosphor displays (the "Licensed Technology"), for Videocon (or a Videocon Group company) to produce and market products, including TVs, incorporating displays utilizing the Licensed Technology. Under the License Agreement, we will receive a license fee of $11 million from Videocon, payable in installments over a 27 month period, with the first installment of $2 million
payable 15 days after the License Agreement is effective. The License Agreement
will be effective after Videocon has obtained the necessary regulatory approvals
in India for the payment of the license fees and royalties and may be terminated
if the required approvals are not obtained in a reasonable period of time. We
will also receive an agreed upon royalty from Videocon based on display sales by
We will continue to have the right to produce and market, and to
utilize Volga Svet Ltd., a Russian display company that we have been working
with for more than ten years, and an Asian company that we have been working
with for more than four years, to produce and market, products utilizing the
Licensed Technology. Additional licenses of the Licensed Technology to third
parties require our joint agreement with Videocon.
Are we and/or Keesmann aware of this and what are we and/or Keesmann doing about it, now, in the past or in the future??

Our new technology improves on our prior carbon nanotube and proprietary
low voltage color phosphor display technology. We have developed various
engineering models using such prior technology, which demonstrated the display's
ability to show movies from DVD players by controlling the brightness of
selected individual pixels. The carbon nanotubes, which are supplied to us by a
U.S. company, require a low voltage for electron emission and are extremely
small - approximately 10,000 times thinner than the width of a human hair. The
5.5 inch (diagonal) display we developed has 960 x 234 pixels and utilizes a new
memory-based active matrix thin film technology with each pixel phosphor
activated by electrons emitted by a proprietary carbon nanotube network located
approximately 10 microns (1/10th of a human hair) from the pixels. As a result,
each pixel phosphor brightness is controlled using a maximum of only 40 volts.
The carbon nanotubes and proprietary color phosphors are precisely placed and
separated utilizing our proprietary nanotube and phosphor deposition technology.
We have developed a process of maintaining uniform carbon nanotube deposition
independent of phosphor deposition. We have also developed a method of enhancing nanotube electron emission to increase the brightness of this type of display.
Some other characteristics of our display technology are as follows:
o We have developed a proprietary system which allows us to evacuate our
display; to rapidly vacuum seal it at a low temperature to accommodate
the matrix; and to create lithographic type spacers to assemble our
display utilizing only 0.7mm glass. We thus obtain a display thickness
of approximately 1/16th of an inch, thinner than LCD (liquid crystal)
and PDP (plasma) displays.
o The display matrix, phosphor excitation system, and drivers are all on
o Our display is able to select and change the brightness of each
individual pixel, requiring only 40 volts on each pixel phosphor to
change the brightness from black to white. This compares to thousands
of volts required for other video phosphor based displays, which leads
to inherent breakdowns and short life.
o Our display has no backlight. Because power is only consumed when a
pixel is turned on, low power is needed to activate the whole display.
The display requires less than 20% the power required by an LCD. This
low power consumption could potentially allow use of rechargeable
batteries to operate TV products for wireless applications and extend
the battery operation time for portable devices.
o The same basic display technology could potentially be utilized in
various size applications, from hand-held to TV size displays.
o Our proprietary matrix structures can be produced by existing mass
production TFT (thin film technology) LCD facilities, or portions of
o Our display eliminates display flicker.
o Our display has an approximately 1,000 times faster video response
time than an LCD, and matches the response time of a cathode ray tube
o Our display can be viewed with high contrast over approximately a 180
degree viewing angle, in both the horizontal and vertical directions,
which exceeds the viewing angle of LCDs.
o Also like CRTs, our display is capable of operating over a temperature
range (-40(degree)C to 85(degree)C) which exceeds the range over which
LCDs can operate, especially under cold temperature conditions.
We believe our displays could potentially have a cost similar to a CRT and
thus less than current LCD or PDP displays (our display does not contain a
backlight, or color filter or polarizer, which represent a substantial portion
of the cost of an LCD).
