防眩显示屏闪耀点的研究进展

Research progress of sparkle on anti-glare display

闪耀点(Sparkle)是影响防眩屏幕显示效果的重要因素之一,为满足人们对显示屏分辨率日益提高的要求,闪耀点越来越受到关注。但目前对闪耀点的确切定义,产生原因,表征手段及评价指标等尚无统一的认识和标准。本文从闪耀点现象入手,介绍了目前闪耀点主要的研究表征方法,例如Gollier和Becker各自提出了表征闪耀点的评价测试体系并给出了一系列相关参数;Evans等人在Gollier和Becker工作的基础上进行了一系列心理物理学实验来评价闪耀点现象的实际效果等等。本文就闪耀点的研究现状进行了详尽的综述,为后续屏幕闪耀点研究,建立统一的评价方法与标准提供了宝贵的参考资料。

Sparkle is one of the main factors which have a significant influence on anti-glare display.As the requirements of display resolution continue to improve,more and more attention has been focused on the sparkle.But up to now,there is no uniform knowledge and standards on the exact definition,the cause,the characterization methods and evaluation indicators of sparkle.The Sparkling phenomenon and definition are introduced in this paper.According to measurement,sparkle＇s current representation methods are divided into two categories：artificial identification and objective analysis,and the main research methods are summarized in this paper.For example,Gollier and Becker presented the evaluation systems of the sparkle and give the related parameters respectively.Other researchers like Evans did some psychophysical experiments to evaluate the effect of the sparkle based on the work of Gollier and Becker.The research progress of sparkle on anti-glare display are reviewed systematically in this article.It will provide a valuable reference for further study on the sparkle and help to set standardized evaluation methods and criterion in the future.
