With this metric, one can predict, in any direction of the color space, the detection threshold of sinusoidal color variations. The metric includes the angular size, spatial frequency, luminance, and chromaticity of the grating. The metric is based on the Riemannian color difference metric for split fields that we developed earlier and models for contrast sensitivity functions of the isolated achromatic, red–green, and blue–yellow detection mechanisms. We validated the models of the contrast sensitivity functions against various datasets. The color difference metric was validated against datasets of isoluminous chromatic Gabor gratings at various spatial frequencies and various color centers. We found adequate agreement with these datasets.

A number of these artifacts stem from conflicts in the visual system. Vergence–accommodation conflicts (VAC), that is, the mismatch between vergence demand (driven by the horizontal binocular disparity of the augmentation) and the accommodative demand (driven by the focal distance of the display), and their impact on visual processing have been well described. However, other conflicts such stereopsis–occlusion conflicts, stemming from the absent or erroneous occlusion of the augmentations when rendered in depth behind a physical object, remain rather underexplored. In this study, we mainly focused on the impact of stereopsis–occlusion conflicts on visual performance.

Conventional mura compensation methods rely on long-exposure imaging to accurately capture subtle brightness inconsistencies, but this approach is time-intensive and unsuitable for high-throughput manufacturing. In this study, we propose a novel method that leverages underexposed image enhancement to estimate mura compensation data using short-exposure imaging. Specifically, we introduce a novel mura compensation loss function designed to minimize discrepancies in compensation data derived from long- and short-exposure images. To facilitate supervised training, we construct a dataset comprising paired long- and short-exposure images of display panels with real and synthesized mura patterns. Our experimental results demonstrate the effectiveness of the proposed approach, showing that the enhancement network trained with the proposed loss function achieves precise mura compensation while significantly reducing imaging time, offering a practical solution for efficient manufacturing processes.</p>\u0000 </div>","PeriodicalId":49979,"journal":{"name":"Journal of the Society for Information Display","volume":"33 9","pages":"955-963"},"PeriodicalIF":2.2,"publicationDate":"2025-07-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144934784","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study explores how they impact visual cognition and reaction efficiency using a dual-phase experimental approach. In Experiment I, a subjective evaluation classified DBC into low, medium, and high levels based on static driving scene images. This was followed by an objective assessment of the complexity of color variety, edge density, and texture features for the selected L-DBC, M-DBC, and H-DBC images. Experiment II then employed eye-tracking metrics (reaction time, mean pupil diameter, and AOI fixation duration) to evaluate participants' visual performance across 10 opacity gradients (0.1–1.0). Results revealed significant interactions between DBC and opacity levels. Under L-DBC, M-DBC, and H-DBC conditions, the relationship between information opacity and reaction times exhibited different phases. To optimize visual cognitive performance, AR-HUD opacity should be set at a minimum of 0.6. When opacity levels are below 0.7, the greater the DBC, the longer the response time for the same opacity. When the information opacity is above 0.7, quicker reaction times can be achieved, regardless of whether the DBC is high or low. These findings offer valuable design guidelines for optimizing AR-HUD text opacity in complex driving backgrounds.</p>\u0000 </div>","PeriodicalId":49979,"journal":{"name":"Journal of the Society for Information Display","volume":"33 8","pages":"919-936"},"PeriodicalIF":2.2,"publicationDate":"2025-07-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145128871","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Metal bonding between the Micro-LED chip and the substrate is one of the most important factors to the light-up yield.
