为了改善FED显示器的显示质量,从FED所特有的光电特性入手,给出了FED显示特性的B-T预校正曲线;并基于目前所采用的标准电视信号作为图像信号源,介绍了FED非线性校正算法。在分析FED三基色色度特性的基础上,介绍了FED色度还原算法的理论模型，并把该校正算法成功应用到FED的视频显示中去,使图像质量得到较好的改善。

Beginning with the FED photoelectric characteristics unique, the B-T pre-calibration curve of the character of FED′s display is given to improve displaying quality of the color field emission display. Base on standard TV signal which used as a image source, the non-linear correction algothm for FED is presented.On the basis of the analysis of characteristics of trichromatic color,theoretical model of the FED chromaticity algorithm is built up.Then the correction algorithm apply to the FED video display to improve the image quality.
