Image display system utilizing light emitting material

A head-up display, comprising:

• a laminated transparency, comprising:
• a first transparent sheet having a first major surface and an opposite second major surface;
• a second transparent sheet having a first major surface and an opposite second major surface;
• an interlayer between and securing the first and second sheets to one another with the second major surfaces of the sheets facing one another;
• and
• at least one light emitting material capable of Up-Conversion of infrared energy into visible radiation defined as Up-Conversion material on the first major surface of the first sheet or between the first major surfaces of the first and second sheets;
• and
• a projection assembly having an electromagnetic radiation source, the projection assembly mounted in spaced relationship to the laminated transparency and configured to direct radiation of one or more selected wavelengths within the absorption band of the at least one Up-Conversion material toward the first surface of the first sheet to impinge on the at least one Up-Conversion material to cause selected portions of the at least one Up-Conversion material to emit light.
