Abstract: Viewable images may be displayed from a substantially dark substrate. Light emitting material may be integrated into a substantially dark substrate. The light emitting material may be configured to emit visible light in response to absorption of ultraviolet light. The light emitting material may include a plurality of light emitting particles and each of the plurality of light emitting particles has a diameter less than about 500 nanometers. For example, emitting visible light from a substantially dark substrate may allow for images to be displayed with relatively high contrast. These high contrast images may appear clearer to a viewer and may result in less eye strain by a viewer.

Abstract: In accordance with embodiments, viewable images can be created in glass. Viewable images may be created in glass by using a projector which projects ultraviolet light to excite light emitting material. Clear images may be created in glass because the size the light emitting particles in the glass is less than 400 nanometers. In embodiments, the visible illumination of a transparent substrate to display an image is possible, while the transparent substrate remains transparent. Accordingly, for example, drivers of automobiles may view images (e.g. map images) on their windshield while they are driving. As another example, window shoppers may view enhanced advertisements in the windows of stores that they are approaching.

Abstract: In accordance with embodiments, viewable imagines can be created in glass. Viewable images may be created in or on glass (or other at least partially transparent substrate), by using microstructures to scatter light from a projector, while the glass maintains transparent or translucent properties. In embodiments, the microstructures are integrated into glass in patterns.

Abstract: A system and a method of a transparent color image display utilizing fluorescence conversion (FC) of nano-particles and molecules are disclosed. In one preferred embodiment, a color image display system consists of a light source equipped with two-dimensional scanning hardware and a FC display screen board. The FC display screen board consists of a transparent fluorescence display layer, a wavelength filtering coating, and an absorption substrate. In another preferred embodiment, two mechanisms of light excitation are utilized. One of the excitation mechanisms is up-conversion where excitation light wavelength is longer than fluorescence wavelength. The second mechanism is down-conversion where excitation wavelength is shorter than fluorescence wavelength. A host of preferred fluorescence materials for the FC screen are also disclosed. These materials fall into four categories: inorganic nanometer sized phosphors; organic molecules and dyes; semiconductor based nano particles; and organometallic molecules.
