LIGHT MIXING CHAMBER FOR USE WITH COLOR CONVERTING MATERIAL AND LIGHT GUIDE PLATE AND ASSEMBLY

摘要

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.
