49.1: Visual Quality System ‐ A Simulation Solution for Mini‐LED LCD Backlight Unit Optimization Targeting on High Quality and Accurate HDR Image Display

Abstract

Local dimming technology has largely increased the effective contrast ratio of mini-LED displays. With suitable backlight and algorithm design, these devices are capable of rendering HDR images with extreme quality. A solution for mini-LED backlight optimization is presented in this work. VQS utilizes deterministic light propagation simulation and spectral analysis to predict display quality from design parameters. It provides display system manufacturers and local dimming algorithm developers a framework to easily optimize their designs.
