Abstract: A white light generating device has at least four pixels where each pixel is a different colored light emitting device (LED) such that the combination of the pixels produces a white light of a desired color temperature upon demand. The LEDs can be organic light emitting devices (OLEDs) or inorganic LEDs. The LEDs can have a microcavity structure for enhanced light output and additionally permitting a broader range of color temperatures than can generally be achieved without the microcavity structure. The color temperature provided by the white light generating device can be changed to achieve different effects. By having at least four colors, more natural aesthetics of illuminated surfaces is achieved, as the reflected light from non-white surfaces is similar to that of reflected natural light.

Abstract: Embodiments of the invention are directed to a layered organic light emitting diode (OLED) device comprising a buckled structure that provides an improved light output relative to flat OLED devices. The buckled structure has a fine buckling with a quasi- periodicity of 100 to 700 nm and a gross buckling of 10 to 20 μm. Embodiments of the invention are directed to a method of producing the OLED device comprising a buckled structure, where a transparent substrate is coated with a transparent elastomeric layer, upon which a thin metal layer of 20 to 100 nm is deposited at an elevated temperature. Upon cooling to ambient temperature, the metal layer buckles with the formation of a fine buckling with a quasi-periodicity of 100 to 700 nm and a gross buckling of 10 to 20 μm. The metal layer is oxidized to a transparent metal oxide layer with the retention of the buckling. Subsequent steps comprising deposition of at least an anode layer, an electroluminescence layer, and a cathode layer forms an OLED that has a buckling structure resulting from the buckled metal structure formed upon cooling.

Abstract: A layered organic light emitting diode (OLED) device comprises a buckled structure over a portion of the light emitting face to provide improved light output relative to flat OLED devices. The buckled structure has a fine buckling and a gross buckling, which are quasi-periodic. Embodiments of the invention are directed to a method of producing the OLED device comprising a buckled structure, where a transparent substrate coated with a transparent elastomeric layer has a thin metal layer deposited on a portion of the elastomeric layer at an elevated temperature. Upon cooling the metal layer buckles with the formation of the quasi-periodic buckling. Subsequently the metal layer is oxidized to a metal oxide layer that retains the buckling. An OLED with a buckling structure over a portion of the emitting face is constructed on the metal oxide layer and retains the buckling of the metal oxide layer.
