Announces a Demonstration Model for Its First Outdoor LCD Billboard AUSTIN, Texas, Jan 30, 2001 /PRNewswire via COMTEX/ -- SI Diamond Technology, Inc. (OTC Bulletin Board: SIDT) through its subsidiary, Electronic Billboard Technology, Inc. (EBT) announces the completion of a demonstration model of an outdoor LCD billboard. The LCD billboard is based on U.S. Patent #5,469,187 issued November 21, 1995, which permits EBT to use discreet LCD's to achieve an outdoor full color, sun-visible electronic billboard. The LCD billboard demonstration model consists of four, one square foot modules with a resolution and structure similar to the electronic billboard installed by EBT at Eckerd stores (see press release of February 1, 2000 "Eckerd and SI Diamond announce an agreement to install digital billboards for outdoor point-of-sale advertising."). The modules are assembled without any visible inter-modular seams and the demonstration model is driven by an exclusive scheme that allows each pixel to directly receive the voltage necessary for optimal operation without the need for an expensive active matrix design. The LCD billboard will enable EBT to utilize multiple manufacturing sources to produce the outdoor billboards at an expected cost of approximately one-third of similar existing outdoor electronic billboard products. EBT is now moving to the manufacturing engineering stage and is initiating discussions with a number of overseas manufacturers for licensing and manufacturing rights. More information is available on the website www.carbontech.net under "LCD billboard." "Due to the vastly reduced cost of the LCD Billboard relative to other outdoor display technologies, we believe the business models for outdoor advertising using digital billboards will be greatly enhanced," stated Marc Eller, Chairman and CEO of SI Diamond Technology.
