Abstract
Spatial computing hardware is challenged by power consumption and thermal management. This research proposes the implementation of brightness foveation using electroluminescent quantum dot (ELQD) displays to dynamically reduce peripheral brightness proportional to human retinal sensitivity. To validate the concept, a custom Python simulation modeling elliptical foveal eccentricity was developed, projecting display power savings of up to 30% by tuning the dimming coefficient k. This would reduce heat generation, increase battery life, and significantly improve user comfort within the computer. The project’s objective is to move from simulation to hardware by executing a feasible fabrication protocol for a bottom-emitting ELQD device, incorporating a core-shell InP emissive layer and a solution-processed layer stack. This work aims to establish reproducible methods for constructing high-efficiency ELQD panels and physically anchor the simulated power-saving models against real device luminance-current-voltage (LIV) characteristics. Psychophysical results via prototype headsets are a separate objective to refine the cited perceptual threshold and brightness presets for peripheral dimming.
