Quarterly Question
Q: Can a ChLCD be backlit?
A: Cholesteric Liquid Crystal Displays are reflective and therefore illumination is from the top side - if necessary. Contact us for topside lighting options.
If you have a question regarding Kent Displays' products or technology please submit your questions . We will select a question from those submitted and publish it along with the answer in a future newsletter.
Announcements
American Display Engineering and Applications Conference 2005 (ADEAC)
Kent Displays will exhibit at the American Display Engineering and Applications Conference to be held at the Doubletree Lloyd Center Hotel & Executive Meeting Center in Portland, Oregon October 24th – 27th. Our standard product line as well as our latest product developments will be exhibited at booth 13.
ADEAC
Presenting: Cholesteric LCDs: Applications, Interface and Integration
The integration and interface issues of bistable reflective ChLCDs will be discussed.
The newly designed interface architecture enables easier and faster integration into OEM devices.
Presenter: Duane Marhefka
October 27, 2005
Portland, OR.
25th International Display Research Conference: EuroDisplay 2005
Presenting: Novel Coated and Transferred Cholesteric Liquid Crystal Display.
A novel reflective ChLCD coated on a single ultra-thin substrate with adhesive back layer is reported. All functional display layers are coated sequentially using conventional coating techniques. After fabrication the display is separated from the preparation substrate and then transferred to any final substrate or surface including fabrics.
The paper also describes the integration of the transferable display with flexible photovoltaic cells to create self-powered displays.

Editor's Notes
Welcome to the Volume 1, issue 4 of Kent Displays, Inc. Quarterly Newsletter: The Liquid Crystal Twist. As the world leader in the research, development and manufacture of Cholesteric Liquid Crystal Display products, it is our hope to bring you interesting and useful information regarding ChLCD technology, products, distributors/representatives and customers each quarter.
In the News
A 16,500 square foot expansion to Kent Displays manufacturing facility at 343 Portage Blvd in Kent, Ohio began in September. The addition will more than double the current size of the operations and is necessary to meet the increased demand for ChLCD products from both the commercial and military sectors.
The addition will include an expansion of the existing 1,350 square foot Class 100 clean room to over 2,000 square feet. Target completion date for the clean room is December 1, 2005. The Production, R&D and Engineering areas will also benefit from the expansion with scheduled staged move-in of those departments starting in Q1 of 2006.
New DARPA Phase Two Funding.
A significant increase in Phase Two funding from past levels has been announced by DARPA (Defense Advanced Research Projects Agency). The funding will be used primarily to continue work in the area of alternative substrates including the commercialization of plastic and fabric displays. Both plastic and fabric displays were demonstrated at The Society of International Display (SID) Conference in Boston this past May.
Photovoltaic Display Advancement Continues.
The Department of Defense Small Business Innovation Research (SBIR) Program has awarded Kent Displays $730,000 over two years to develop a commercial display that is self powering by the integration of a photovoltaic cell and ChLCD. The project is based on Kent’s Combined ChLCD and Solar Cell Assembly Patent: 6, 518,944. Unlike conventional LCDs, Cholesteric Liquid Crystal Displays (ChLCD) absorb all light not reflected. The addition of the photovoltaic cell as the absorbing background permits energy harvesting from light sources.
Legal Action Initiated Against Magink for ChLCD Patent Infringement.
A patent infringement lawsuit was filed by Kent Displays, Inc. against Magink in United States District Court in New York for infringing on its Cholesteric Liquid Crystal Displays (ChLCD) patents. “It is our policy to protect our intellectual property.” according to Joel Domino President of Kent Displays.
He went on to say that “Kent Displays and Kent State University bore the R&D for this technology and Kent will not allow others to unfairly profit from Kent’s and KSU’s innovations.” The lawsuit alleges infringement of Patent Numbers 6,377,321, 5,453,863 and 6,654,080 all owned or exclusively licensed to Kent by Kent State University.
