摘　　要：色串扰是PDP显示屏的一种特殊缺陷。本文先介绍了色串扰的起因,然后提出了一种新的基于光谱辐射度法的色串扰评价方法。该方法首先测量红、绿、蓝单色发光单元的光谱功率分布,然后在显示屏红场、绿场、蓝场下分别测量包含有足够象素(如500象素)显示区域的光谱功率分布,由此建立有关于串扰评价系数的关系式。选择单色发光单元测试结果中包含有足够强光谱功率的波段数据参与计算,计算得到上述串扰评价系数。本文分析了基于该方法的试验结果,并指出光谱辐射度法对于PDP显示屏而言是一种有效的色串扰评价方法。Color crosstalk is a special defect of Plasma Display Panel （PDP）. The causes of the color crosstalk are introduced firstly. Then, a novel method based on the spectroradiometry for color crosstalk characterization is presented. It measures the spectral radiance distribution of red, green and blue homochromous cells. Next, the spectral radiance distributions of the area which includes enough pixels are measured in the red, green, blue full screen. Several equations for the characterization coefficients can be built. The data in the wavelength ranges which include enough spectrum radiance power for homochromous cells are selected to calculate. These coefficients of crosstalk could be easily got in this way. Then, the experimental results of color crosstalk are analyzed. It is indicated that the spectroradiometric method is an effective method for characterizing color crosstalk.
