摘要
随着信息化时代的到来,各种高清数字显示终端设备广泛普及,而由此导致的视疲劳发病率逐年攀升。为研究已有高清数字显示终端对视疲劳的影响,文中采用测试显示器性能指标和招募受试者进行视觉疲劳评测的两条技术路线,对市面上14个厂家生产的84种高清数字显示终端开展测试。客观测评结果表明:液晶电视的蓝光性能指标较高,LED显示屏的闪烁性能指标较高,可能导致视疲劳;平板电脑的观看亮度性能指标较低,可能导致视疲劳;LED显示屏的对比度性能指标较高,可能诱发直接眩光;平板电脑的镜面反射率性能指标较高,可能诱发间接眩光,导致视疲劳。主观评测结果表明:相同时间内,相比于观看液晶电视,观看家用投影仪和OLED电视引发的视疲劳症状更轻。
With the advent of information age,all kinds of high definition(HD)digital display terminals become ubiquitous,resulting in increasing incidence rate of visual fatigue.In order to study the effect of existing HD digital display terminals on visual fatigue,84 kinds of HD digital display terminals produced by 14 manufacturers on the market are tested by using two technical routes of testing display performance indicators and recruiting subjects for visual fatigue evaluation.The objective assessment results show that the performance indexof blue light of the liquid crystal display television(LCD TV)is high,and theperformance indexof flicker of the light⁃emitting diode(LED)display screen is high,which may lead to visual fatigue.The luminance of the tablet computer is low,which may lead to visual fatigue.The contrast ratio of the LED display screen is high,which may induce direct glare,and the mirror reflectivity of the tablet computer is high,which may induce indirect glare,resulting in thevisual fatigue.The subjective evaluation results show that the symptoms of visual fatigue caused by watching home projector and OLED TV are lighter than watching LCD TV in the same time.
