Image display system utilizing light emitting material

A display system comprising:

• at least one light emitting material having an absorption band carried on a support;
• a protection assembly having an electromagnetic radiation source, the protection assembly configured to direct radiation of one or more selected wavelengths within the absorption band of the light emitting material toward the light emitting material to cause at least a portion of the light emitting material to emit light;
• wherein the support comprises a sheet having at least one light emitting material having a predetermined absorption band and a major surface, and further comprising a layer substantially non-transparent to wavelengths within the predetermined absorption band over a portion of the second major surface of the sheet, wherein the electromagnetic radiation source of the protection system is capable of generating at least one beam having at least one selective wavelength within the absorption band, the protection assembly further comprising a movement device configured to direct the beam toward the sheet to impinge the beam on the light emitting material and to move the beam over the major surface of the light emitting material to cause at least a portion of the light emitting material to emit wavelengths at least in a range of 380 nanometers to 760 nanometers of the electromagnetic spectrum defined as the visible region, and
• further comprising a member passing less than 50% of the wavelengths within the predetermined absorption band impinging on the member, the at least one light emitting material between the member and the first ply.

A head-up display system, comprising:

• at least one light emitting material having an absorption band carried on a laminated transparency, the 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 having an absorption band on the first major surface of the first sheet or between the first major surfaces of the first and second sheets, and
• a protection assembly having an electromagnetic radiation source, the projection assembly mounted in spaced relationship to the laminated transparency and configured to direct the radiation of one or more selected wavelengths within the absorption band of the at least one light emitting material toward the first surface of the first sheet to impinge on the at least one light emitting material to cause selected portions of the at least one light emitting material to emit light.

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.

A method of displaying images, the steps of:

• providing a support having at least one light emitting material, and controlling and directing electromagnetic radiation from a radiation source to cause the at least one light emitting material to form an image, wherein the controlling and directing step is practiced by:
• selectively moving at least one beam of radiation of one or more selected wavelengths in a direction defined as a first direction toward a surface of the support defined as a first surface, the first surface of the support having the light emitting material, wherein the light emitting material is selected from materials having an absorption band, a material capable of Up-Conversion into visible radiation and mixtures thereof;
• and
• displacing the radiation beam and the light emitting material relative to one another during the practice of the selectively moving step to selectively impinging at least one radiation beam having a wavelength in the electromagnetic spectrum on the light emitting material to cause the light emitting material to emit light to form the image, the image having a predetermined configuration, while
• preventing transmission of radiation of wavelengths within the absorption band in a direction toward a surface defined as a second surface of the support, wherein the first surface of the support is opposite the second surface of the support.
