High fidelity mini-LED backlit liquid crystal displays

Abstract

Mini-LED backlit liquid crystal display (LCD) exhibits premium display performance, benefiting from the new design space enabled by the mini-LED backlight unit: the flexibility in subframe sequential illumination enables motion blur reduction; the selective illumination of bright zones and dark zones offers high dynamic range, good sunlight readability and power saving; the high zone density suppresses the visual artefact of ‘halo effect’ that is commonly observed in conventional local dimming LCDs. In this paper, we discuss limiting factors and solutions to achieve high display fidelity regarding the abovementioned performance metrics.
