【摘要】 采用国际通用的心理物理学实验,通过对点间距为1.67mm,总尺寸为1600mm×1200mm的大尺寸彩色LED显示屏进行视觉舒适性的主观评价实验,得到了不同环境照度下的LED显示屏的最佳显示亮度的主观实验数据。采用数据拟合等算法建立了与环境照度相匹配的大尺寸彩色LED显示屏亮度调节模型,实现了将主观实验数据客观化。实验结果表明:拟合数据模型与实验数据吻合较好,该模型能较好地反映环境照度与大尺寸彩色LED显示屏最佳显示亮度的对应关系;采用该数据模型,在同等观看条件下,大尺寸彩色LED显示屏与液晶LCD电视的视觉舒适性没有明显差异。更多还原

【Abstract】 This paper uses a large size LED color screen with 1. 67mm- pixel pitch,1600mm* 1200 mmsize to do the subjective assessment,gets serials subjective experiment data of LED best luminance for human visual comfort at different ambient illuminance,and builds an objective model by fitting calculation with these subjective experiment data. The results show,the fitting objective model matches the subjective experiment data well,and can show the relationship of LED best luminance of human visual comfort at various ambient illuminance; by using this model for LED color screen,there is no obvious visual comfort difference between LED color screen and LCD screen at the same viewing condition.更多还原
