Ultra-compact Highly Directional Pixel Technology

Attributes such as the Radiative Decay Rate (RDR) and the Radiation Pattern (RP) of Quantum Dots (QDs) are highly sensitive to their nearby surrounding material. To enhance the RDR and shape the RP, interspacing between the QDs and their distances from discontinuities caused by multi-layered environment in which they are immersed, must be controlled with nanoscale accuracy. State of the art in QD based micro-display has so far ignored these aspects of light-matter interaction in pixel design and therefore has been unable to harness the full potential of QDs in pixel size reduction. I propose a novel pixel technology for dynamic micro-displays with novel capabilities such as (1) Each submicron pixel being operable electrically yet independently (i.e. the ability of turning a pixel on/off being independent from the neighboring pixels, hence the infinite contrast ratio. (2) Highly directional light being emitted from each pixel and (3) Increased quantum yield and luminescence while decreasing the number of QDs per pixel, hence minimizing the power consumption
