摘要
介绍了平板显示器(FPD)非线性校正的经典常用算法,简要说明了FED非线性校正所具有的特点。着重讨论了场致发射显示器(FED)所具有的显示特性,给出了FED显示特性的B-T预校正曲线,并基于目前所普遍采用的标准电视信号作为图像信号源,提出了FED非线性校正算法。利用行消隐时间来处理非线性校正过程的方法,达到实时图像显示和减少硬件成本的目的。给出了基于PW113的系统设计方案,该方案成功地运用于25英寸彩色FED非线性校正电路中,为系统提供了优质的图像。最后,给出了该算法与经典算法的实验对比图。
The general method of Flat Panel Display （FPD）nonlinear correction is introduced in this paper,specification of the character of Field Emission Display （FED） nonlinear correction is explained. And the characteristics of display of FED is deeply discussed. Then B- T pre-correction curve of the character of FED＇s display is given, and the arithmetic of nonlinear correction of FED is provided. A project of a system design based on PW113 is proposed. The project has been successfully used in the circuit of 25 inch color FED nonlinear correction which provides excellent video source. Finally, the contrast graphics between the arithmetic in this paper and the general arithmetic is provided.
