Abstract: A light mixing chamber includes a housing having a channel formed therein, with the channel exposed to an exterior of the housing. A chamber is formed in the housing, and an aperture formed in the housing connects the chamber to the channel. The chamber may house an LED, with an optical member being retained within the channel. A light guide plate may be positioned on an exterior of the housing outside the channel.

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.
