    Abstract: Packaged chip-on-board (COB) LED arrays are provided where a color conversion medium is distributed within a glass containment plate, rather than silicone, to reduce the operating temperature of the color conversion medium and avoid damage while increasing light output. In accordance with one embodiment of the present disclosure, a lighting device is provided comprising a chip-on-board (COB) light emitting diode (LED) light source, a light source encapsulant, a distributed color conversion medium, and a glass containment plate. The COB LED light source comprises a thermal heat sink framework and at least one LED and defines a light source encapsulant cavity in which the light source encapsulant is distributed over the LED. The glass containment plate is positioned over the light source encapsulant cavity and contains the distributed color conversion medium. The light source encapsulant is distributed over the LED at a thickness that is sufficient to encapsulate the LED and define encapsulant thermal conduction paths TPE extending through the light source encapsulant to the thermal heat sink framework from the distributed color conversion medium.

    Abstract: Methods of forming polarized panes for variable transmission windows are disclosed. The polarized panes are formed from transparent substrates that are brushed with a brushing pattern that varies continuously in a select direction over each of one or more periods. A layer of polarizable material such as POLARCOAT material can be deposited on and responds to the brushed surface by forming a polarization pattern that substantially matches the brushing pattern and thus also includes one or more periods.

    Abstract: A lighting device is provided comprising a chip-on-board (COB) light emitting diode (LED) light source, a phase transfer fluid disposed in a hermetically sealed phase transfer fluid chamber, a phase transfer fluid wicking structure, a distributed color conversion medium, and a glass containment plate. The color conversion medium is distributed in two dimensions over an emission field of the lighting device within the glass containment plate. The COB LED light source comprises a thermal heat sink framework and at least one LED and defines the hermetically sealed phase transfer fluid chamber in which the phase transfer fluid is disposed. The glass containment plate is positioned over the hermetically sealed phase transfer fluid chamber and contains the distributed color conversion medium. The phase transfer fluid wicking structure is transparent to at least a portion of the operating wavelength bandwidth of the LED and is configured within the hermetically sealed phase transfer fluid chamber to encourage transport of phase transfer fluid, permit vaporization of transported phase transfer fluid, and receive condensed phase transfer fluid vapor.

    Abstract: Methods and apparatus provide for a touch sensitive display, in which a transparent layer is disposed over a display layer; light is directed to propagate into and/or through the transparent layer; scattered light is measured in response to an object touching a surface the transparent layer and disturbing the propagation of the light therethrough; and one or more positions at which the object touches the transparent layer are computed based on signals obtained by the step of measuring the scattered light.

    Abstract: A storage medium includes a base substrate, a first metallic layer, a first border region, and a first cover substrate. The base substrate includes a first side and a second side. The first side and the second side oppose one another. The first metallic layer defines a first pattern. The first metallic layer directly abuts the first side of the base substrate. The first border region extends about the first pattern. The first cover substrate is positioned against an exposed surface of the first metallic layer such that the first metallic layer is positioned between the first side of the base substrate and the first cover substrate. The first cover substrate is coupled to the first border region.

    Abstract: A backlight includes a substrate, a plurality of light sources proximate the substrate, a first reflective layer on the substrate, and a plurality of patterned reflectors over the plurality of light sources. Each light source includes a size measured in a plane parallel to the substrate. Each patterned reflector is aligned with a corresponding light source and includes a thickness profile.
    The thickness profile includes a substantially flat section and a curved section extending from and surrounding the substantially flat section. The substantially flat section varies in thickness by no more than plus or minus 20 percent of an average thickness of the substantially flat section. The substantially flat section includes a size in a plane parallel to the substrate equal to or greater than the size of each light source.

    Abstract: A projection screen for displaying an image is disclosed. The projection screen may comprise an electrode, a plurality of cavities, an upper and lower substrate, and a hydrophobic liquid. The electrode may be disposed on a lower substrate. The hydrophobic liquid may be disposed between the upper substrate and lower substrate. The plurality of cavities may be disposed between the upper and the lower substrates. The projection screen may be associated with the electrode. The projection screen may be configured such that an application of an appropriate voltage to the electrode changes optical properties of the projection screen. Optical properties of the projection screen may comprise transparent and opaque states. Modulation between transparent and opaque states may be in such speed that a viewer sees the projection of a projector on the projection screen in the opaque state as well as sees through the projection screen in the transparent state with no perceived interruptions.
