| 摘 要： | 针对等离子体显示普遍存在的大面积闪烁现象,提出了一种基于时变光信号亮度测量系统的大面积闪烁客观评价方法。时变光信号亮度测量系统利用光电管和亮度计,实现了对显示屏输出光信号亮度值随时间变化的快速、准确记录。基于阴极射线管显示临界闪烁频率估算模型,通过主观视觉感知实验,利用测量系统得到亮度随时间的变化关系,建立了平均感知闪烁程度估算模型。估算模型输出结果与视觉感知实验数据相关系数达到0.98。该测量系统与估算模型实现了对等离子体显示大面积闪烁的客观度量,并与主观视觉感知实验结果相吻合,是等离子体显示屏优化设计和显示行业标准建立的有效工具。

| Abstract: | An objective characterization method for large area flicker of plasma display panel is proposed.A measuremental setup based on a photo diode and a luminance meter,was built to record the light behavior quickly and accurately.Based on model of critical flicker frequency calculation for cathode ray tube,an analytical model was built to predict the perceived large area flicker seriousness level based on the measured light behavior.The output of the analytical model had a coefficient of correlation as high as 0.98 with perception experimental results.The measuremental setup and the simulative model enable objective evaluation for large area flicker of plasma displays,it is consistent with experimental results.It helps with plasma display panel design optimization and industrial standardization. |
