Halo visibility data of measured FALD LCDs is used to test different halo perception metrics. A focus is the determination of the evaluation area as it highly impacts the setup conditions of mask-free halo measurements. Some of the metrics show an excellent correlation to human perception and can be considered as possible halo perception candidates for future studies.
