摘　　要：针对场致发射显示器(FED)自身的器件特性,提出了一种基于改进型Newton算法的缩放方案。FED缩放系统采用改进型Newton算法,针对FED的对比度低和低灰阶丢失的器件自身特性,在Newton插值算法基础上选择最优的参数和加入补偿系数,在补偿效果和运算复杂度上比传统的缩放算法具有明显的优势。将采用本文算法的FED缩放系统应用于驱动FED显示上,视频显示图像的对比度得到提高,低灰度丢失部分得到一定的补偿,图像画质更为细腻。Due to the features of the field emission display（FED）,a zooming scheme based on improved Newton algorithm is proposed is this paper.The FED zooming system is based on the improved Newton algorithm,which can effectively alleviate the low contrast and the low gray-scale lost of the FED.The final effect and complexity have more obvious advantages than the traditional zooming methods by selecting the optimal parameters and adding compensating coefficients on the basis of the Newton interpolation algorithm.When applied to the display of the FED,the zooming system with the proposed algorithm can significantly enhance the contrast and compensate the lost of low gray-scale,so that the final image will be more delicate.
