Abstract
A color micro-LED display chip includes light-emitting diodes (LEDs) and quantum dot (QD) containers that contain quantum dots. The QD containers are positioned to receive light emitted from the LEDs. The QD containers are shaped to have an entrance face, an opposing exit face and a waist located between the two faces. The waist has an area that is less than an area of one of the faces and less than or equal to an area of the other face.
Claims21
A device comprising:
- a plurality of light-emitting diodes (LEDs);
- and
- a plurality of quantum dot (QD) containers positioned to receive light emitted from the plurality of LEDs, the plurality of QD containers shaped to have two faces and a waist located between the two faces, the two faces comprising an entrance face and an exit face opposing the entrance face, the waist having a cross-sectional area that is less than a cross-sectional area of each of the entrance face and the exit face;
- wherein the plurality of QD containers have straight, tapered sidewalls between the waist and each of the entrance face and the exit face, each sidewall forming a sidewall angle with respect to a longitudinal axis of the QD container;
- and the sidewall angle of the sidewalls between the waist and the entrance face is different than the sidewall angle of the sidewalls between the waist and the exit face.
