    摘要: A light emitting sign comprising a plurality of blue LEDs operable to generate blue excitation light and a light emitting display surface comprising a light transmissive substrate and at least one phosphor overlaying at least a portion of one face of the substrate. The phosphor is configured to absorb at least a portion of the blue light generated by the LEDs and, in response, to emit light of a selected color other than blue. Regions of the display surface intended to generate blue light do not include the phosphor.

    摘要: Reflective, low-cost display pixels and displays incorporating magneto-optical elements wherein an externally applied magnetic field is perpendicular to an axis of rotation of the magneto-optical elements and parallel to a viewing plane of a display made from these elements. The display elements have a restricted rotation about their long axis which can be actuated by an external magnetic field to produce a bistable, electronically writable image. In addition, architectural modifications to this arrangement can be made such that the power required to write the image to such a display is decreased, overall display efficiency is increased and cross-talk between pixels is nearly eliminated.

    摘要: A light emitting sign comprising a light box housing a plurality of blue LEDs operable to generate blue excitation light and a light emitting display surface overlaying the light box opening. The light emitting display surface comprises a light transmissive substrate configured as a light transmissive window such that light generated by the sign is emitted from the substrate and a phosphor overlaying at least a portion of one face of the substrate. The phosphor is configured to absorb at least a portion of the blue light generated by the LEDs and, in response, to emit light of a selected color.

    摘要: A light source comprises a blue emitting LED operable to generate blue excitation light and a light emitting surface comprising a light transmissive substrate and a phosphor. The LED is configured to irradiate the light emitting surface with excitation light such that the phosphor emits light of a second wavelength and wherein light emitted by the source comprises a combination of blue light from the LED and the second wavelength light from the phosphor. The light emitting surface is interchangeable thereby enabling the source to generate different selected colors of light using the same LED. The phosphor can be provided as a layer on the substrate or incorporated within the light transmissive substrate. The light emitting surface can be configured as a waveguide or as a light transmissive window.
