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.
► We used optical coherence tomography (OCT) to perform nondestructive inspection of liquid crystal display (LCD) for defects. ► We construct 3D images of the LCD panel and confirm the 3D shape and vertical location of eventual defects in the LCD panel. ► It gives users more direct and relevant information about defects than other display inspection technique.
