AB - The present communication reports a study on polarized light emission from sidewalls of light-emitting-diode (LED) dies with future interest in color display applications, e.g., liquid-crystal display (LCD) backlighting. Commercial LED dies with three primary colors were subjected to polarization characterization via a confocal microscope. AlInGaP red LED dies (cube shape) were shown to emit polarized light with a polarization ratio of 0.47. InGaN-based blue (sapphire substrate) and green (SiC substrate) LED dies were revealed to possess polarization ratios as high as 0.9 on side emission from epitaxial layers. These results ensure the potential of commercially available LED dies for LCD backlighting experiments. Discussions were made on improvement in polarization characteristics.
