An apparatus (e.g. a display) including a display substrate and a waveguide. The waveguide may guide ultraviolet light from the light source onto the display substrate. The display substrate may include light emitting material configured to emit visible light in response to absorption of the ultraviolet light.

Waveguide display

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.

Display having integrated light emitting material

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.

Excitation light emission apparatus

Emission of visible light in response to absorption of excitation light

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.
