  • Patent number: 9535282
    Abstract: A system and method are disclosed employing a dielectric mirror layer, highly reflective at wavelengths below a cut off but highly transparent at wavelengths above the cut off, is placed within a display assembly. This dielectric mirror layer creates a very efficient reflecting cavity for a portion of a Light Emitting Diode (LED) pumping spectrum. Accurate dielectric filter tuning allows an increased portion of the pumping spectrum to be converted to desired wavelength spectrum and also raise the luminance ratio of the display to a useful value for display applications. Variable and active tuning of the cut off wavelength value functions to optimize system performance.

  • Patent number: 9529220
    Abstract: In the electro-optical device, a pillar-shaped protrusion is formed on an insulating film (a first insulating film) provided below a pixel electrode in the downward direction, and thus a conduction section of a second electrode layer (a conductive layer) overlaps the highest surface of the pillar-shaped protrusion. An inter-layer insulating film (a second insulating film) is provided between the second electrode layer and the pixel electrode, but the conduction section is exposed on a surface of the inter-layer insulating film. For this reason, the pixel electrode is electrically connected to the conduction section, when the pixel electrode is laminated on the inter-layer insulating film.
