摘　　要：针对轨道交通车载LED显示屏滚动显示过程中,当滚动速度较慢,即滚动间隔时间较长时,人眼会感觉到屏幕存在亮度闪烁的问题,文章开展了相关研究与分析。首先介绍了项目中LED显示屏产品的系统构成、LED显示屏显示原理,随后考虑了人眼视觉暂留、人眼亮度对比效应等人眼视觉特性,并对LED显示屏滚动显示过程的人眼感知影像强度进行了建模与定量分析,提出了问题解决建议。In course of scrolling display of the on-board LED display screen for rail transit,at a lower scrolling speed,that is,a longer scrolling interval,human eyes can feel the luminance flicker of the screen.The article studies and analyzes this problem.It firstly introduces the system composition and the display principle of the LED screen,then takes into account the human visual system such as persistence of vision and luminance contrast effect,and it makes modeling and quantitative analysis of the intensity of the images precepted by human eyes in course of scrolling display of the LED screen and proposes solutions for this problem.
