Title
Nondestructive defect inspection for LCDs using optical coherence tomography.
Abstract
In this study, we used optical coherence tomography (OCT) to perform nondestructive inspection of liquid crystal display (LCD) for defects. By using OCT, we obtain tomograms and two-dimensional images of LCD panels. Based on these images, we construct three-dimensional images of the LCD panel and confirm the three-dimensional shape and vertical location of eventual defects with in the LCD panel. This nondestructive and effective defect-inspection method for LCD using OCT that gives direct results and is applicable for detecting defects in flat panel or flexible displays.
