  • Light mixing chamber for use with color converting material and light guide plate and assembly
    Patent number: 9851497
    Abstract: A light mixing chamber of a backlight includes a housing having a channel and a chamber exposed to the channel, an LED positioned within the chamber, and a capillary containing quantum dots positioned in the channel. A light guide plate is positioned adjacent the housing and adjacent the capillary. Relative dimensions of the elements of the light mixing chamber, as well as features added to the elements of the light mixing chamber, can be varied to balance efficiency and uniformity of light generated in the backlight.
    Type: Grant

  • Component attach methods and related device structures
    Patent number: 7993940
    Abstract: A method, and associated apparatus, for attaching a component (e.g., an electronic and/or optoelectronic component) is provided which can facilitate low-voiding of an attachment layer. The method includes disposing an attachment material layer over a surface, providing the component having a backside surface, disposing a portion of the backside surface of the component over a first portion of the attachment material layer such that a substantial portion of the backside surface of the component is not disposed over the attachment material layer, and moving the component such that the component is attached to at least a portion of the attachment material layer that is substantially larger than the first portion of the attachment material layer. The attachment material can include a solder.
