近眼显示设备用液晶显示屏亮度非均匀性及人眼视觉感知实验研究OA

This study aims to investigate the impact of brightness non-uniformity in liquid crystal displays(LCDs)used in near-eye display devices on human visual perception.First,in accordance with the International Display Measurements Standard(IDMS),brightness non-uniformity was adopted as the core metric to test the non-uniformity of a batch of typical 5.46-inch LCDs for near-eye display devices from a development institute.Second,based on two core indicators—monocular brightness non-uniformity and binocular brightness non-uniformity difference—10 sets of samples were selected as research objects for further analysis.Finally,human factors experiments were conducted to explore the correlation between these two core optical indicators and human visual perception.The experimental results showed that when the monocular brightness non-uniformity is below 20%and the binocular brightness difference does not exceed 10%,90%of the participants failed to perceive any obvious visual difference when observing through a dedicated inspection machine that simulates the performance of a full 5.46-inch near-eye display device.Therefore,this paper emphasizes that when evaluating the brightness non-uniformity of LCDs for near-eye display devices,focus should not only be placed on monocular brightness non-uniformity,but the binocular brightness non-uniformity difference should also be comprehensively considered.This research provides technical support for LCD manufacturers and near-eye display device integrators to formulate scientific product acceptance benchmarks,which holds significance for enhancing the visual experience of near-eye display devices.
