SYSTEMS AND METHODS FOR IMPROVED DISPLAYS

This abstract first appeared for US patent application 18464201 titled 'SYSTEMS AND METHODS FOR IMPROVED DISPLAYS

Original Abstract Submitted

An optical element includes a planar body having a circular profile including a plurality of annuli of decreasing width with increasing radius, where the circular profile includes a sequential arrangement of: (a) a first annulus including alternating azimuthal segments of high and low refractive index materials, (b) a second annulus including the high refractive index material, (c) a third annulus including alternating azimuthal segments of the high and low refractive index materials, and (d) a fourth annulus including the low refractive index material. The optical element may be configured to increase the light extraction efficiency and directionality of light output from a light emitting diode.
