摘要

本文介绍了一种用于TFT-LCD单元模块缺陷检测的硬件，该硬件封装在带有FPGA和DSP处理器的pci板中。TFT-LCD单元模块的图像通常包含周期性的单元图案，这使得检测缺陷变得困难。我们提出了一种利用幅度谱分析消除小区图案的有效而强大的算法。

Fourier spectrum based periodic cell pattern elimination in thin film transistor liquid crystal display cell image

This paper presents a hardware that inspects defects on TFT-LCD cell modules and packed in a PCI-board equipped with FPGA and DSP processors. Images of TFT-LCD cell modules normally contain periodic cell patterns which make it difficult to detect defects. We propose an efficient and powerful algorithm for elimination of the cell pattern using magnitude spectrum analysis.
