摘要

冷阴极荧光灯(CCFL)作为液晶显示器的背光源被广泛使用。检查CCFL缺陷最常见的方法是用肉眼检查。这种肉眼检查可能导致检查不一致和工业灾难。拍摄环境和检测算法是实现CCFL缺陷自动检测的关键。本文提出了一种基于侧光拍摄环境的CCFL缺陷检测算法。实验结果表明,CCFL缺陷检测过检率为4.65%,缺陷检测不成功率为5.37%。

LCD BLU Defects Detection System with Sidelight
A Cold Cathode Fluorescent Lamp(CCFL) is used as a LCD Monitor`s backlight widely. The most common way to check CCFL`s defects is an examination with the naked eye. This naked eye examination can cause examination inconsistencies and industrial disasters. A shooting environment and detection algorithms are important for finding CCFL defects automatically. This paper presents CCFL defect detection algorithms using images captured under the shooting environment with sidelight which is one of the shooting environment we have suggested. The experimental result shows 4.65% of overdetection and 5.37% of unsuccessful defect detection of CCFL.
