The Luckoff Display Holographic Optical Switch Technology may be incorporated into the following markets:

	Flat Panel Display/High Definition Television/Projection Displays
	Telecommunications
	Cosmetic Holographic Optical Diffractive Contact Lenses
	Hand-Held Spectra-Reflectometer
	Compact Spectrometer

Discussions involving the Luckoff Display Corporation technology in regards to the above markets is as follows:

In regards to LDC's patent US 5,613,022 "Diffractive Display and Method Utilizing Reflective or Transmissive Light Yielding Single Pixel Full Color Capability," the generic essence for this invention is that by varying the effective spacing of the diffraction pattern, this will control the selected diffracted energies generated. In otherwards, by movement of the holographic diffraction grating, such as by piezoelectric elements, manostrictive elements, magnetic coils technologies, electrostrictive, mems, and the like, generates different colors by varying the incident light on that element that would be emitted to a stationary observer at any location of viewing. This new and proprietary technology may be utilized for direct view digital flat panel displays and projection displays. One method for constructing these displays may utilize magnetic coil holographic and diffractive optics. This technology is able to generate the entire color spectrum at video speed for each individual pixel. Therefore, with this technology, an electronic display no longer requires the standard RED, GREEN, and BLUE pixel's blended together to create a pixel of color. In the case of the Luckoff Display Array, color is a function of applied voltage. An example of the feature is as follows: When viewing the Luckoff Display Array with no voltage applied, the pixel has the color green. When voltage is applied in the positive direction, the pixel changes to blue (when applied in the negative direction, the pixel changes from green to red). Consequently, by applying voltage to a magnetic copper coil material with a holographic diffraction grating on it, the colors green, blue, and red (and all other colors of the spectrum) can be obtained by applying a plus or minus voltage. Therefore, it is possible to have an array of devices where each element (each pixel) has a diffraction grating on it, which moves independently of the others. A color display can then be fabricated where each pixel is capable of generating the entire color spectrum thus increasing the color resolution over conventional techniques (which require the combination or red, green and blue lights to form the desire color).

The Luckoff Display Array is a revolutionary method of displaying electronically programmable information in standard methods and in the new digital video format. Current technology does not provide the color resolution and changeable message capabilities that the Luckoff Display Array will have. In fact, the Luckoff Display Array has eliminated many of the problems that are prevalent in other automated display systems.

The Luckoff Display will include all of the following special attributes:

1.	The first true large flat panel high-resolution display screen for outside/inside use;
2.	A clear resolution by using 625 pixels per square inch, with each pixel having full color spectrum capability thus providing a 1,875 factor improvement in resolution when compared to current systems that use three primary colored pixels to provide full color;
3.	Brilliant retro-reflective display visible at all hours of the day - including direct sunlight;
4.	Wide viewing angle;
5.	Real time video at 30 frames per second;
6.	Rugged construction;
7.	Low power usage;
8.	Low maintenance;
9.	Unaffected by temperature (hot or cold) or by humidity;
10.	Remotely programmable;
11.	User friendly operating software - based on the Windows 95 platform;
12.	Digital video capability.

Another important element of the Luckoff Display Array is its wide field of view. The display array can be rotated and viewed from a number of angles without reducing the quality of the color or resolution.

The capabilities of the Luckoff Display Array invites a plethora of possibilities for achievable applications. With its visibility in direct sunlight, full color graphics, variable update capability, low maintenance, energy efficiency and resistance to extremes in temperature and humidity, the Luckoff Display Array has the potential for transforming each potential application into reality. Please refer to patent # US 5613022 "Diffractive Display and Method Utilizing Reflective or Transmissive Light Yielding Single Pixel Full Color Capability."

In the "Diffractive Display," US 6,621,607 B1 and US 6,898,009 B2, we are rotating the holographic diffraction pattern generating a display using the diffracted light from the holographic diffraction grating. We can probably achieve pixel densities far greater than the current densities set forth for high definition TV. We are very excited about this new discovery.

In regards to telecommunications applications we are using LDC technology as an optical switch/signal within a single fiber optic cable. Our engineers feel that we can achieve up to 1000 lines of color switched within a single fiber optic cable. LDC's technology can enhance multi/demutiplexors by increasing their capacity, information mixing and decoding capability. Please refer to pending patent application # 20010033419 "Direction of Optical Signals by a Movable Diffractive Optical Element."

The technology maybe utilized to create logo's on to a contact lenses. See US 7,018,041 B2 "Cosmetic Holographic Optical Diffractive Contact Lenses." The Hand-Held Spectra-Reflectometer US 7,209,230 B2 and Compact Spectrometer US 7,233,394 B2 are our latest inventions!
