Detailed Successive Layer Modeling and Design Factor Analysis for Single Micro-LED Pixel

The major factors associated with the manufactured structures and photon emission intensity distribution must be accurately identified for complicated optical design parameters micro-LED pixels. This study presents methodologies reveals sequential calculating protocol in each layer pixel-level simulations, based on which boundary condition errors common simulations can corrected. Moreover, effect epitaxial of is revealed, rationality setting finite-radius receiver a pseudo-extended substrate material also explained respect to intrinsic extrinsic pixel-intensity properties. Finally, experiments DOE L 18 orthogonal array table demonstrated by Taguchi method explore principal parameter layers. results indicate that sapphire thickness, P-GaN layer, buffer layers, an additional plate are four significant primarily influence luminous power corresponding uniformity exit pupil micro-LEDs. Based uniformity, signal-to-noise ratio thickness 16.9, extended 9.8, ∼10 times > interaction parameter, such as etching angle reflective index pixel. These specific optimization cost control performance improvement.
