Automatic Detection of Region-Mura Defect in TFT-LCD
Visual defects, called mura in the field, sometimes occur during the manufacturing of the flat panel liquid crystal displays. In this paper we propose an automatic inspection method that reliably detects and quantifies TFT-LCD regionmura defects. The method consists of two phases. In the first phase we segment candidate region-muras from TFT-LCD panel images using the modified regression diagno...
متن کاملAutomatic TFT-LCD Mura Defect Detection using Gabor Wavelet Transform and DCT
Recently, mura defect inspection techniques are receiving attention in LCD production procedure since demands of TFT-LCD are growing. In this paper, we propose an automatic mura defect inspection method using gabor wavelet transform and DCT. First, we generate a reference panel image using DCT based method. For original panel image and generated reference panel image, we apply a gabor wavelet t...
متن کاملAutomatic Detection of Region-Mura Defects in TFT-LCD Based on Regression Diagnostics
In recent days, large-sized flat-panel display (FPD) has been increasingly applied to computer monitors and TVs. Mura defects, appearing as low contrast or non-uniform brightness region, sometimes occur in manufacturing of the Thin-Film Transistor Liquid-Crystal Displays (TFT-LCD). Implementation of automatic Mura inspection methods is necessary for TFT-LCD production. Various existing Mura det...
متن کاملLcd Mura Detection with Multi-image Accumulation and Multi-resolution Background Subtraction
We integrated the techniques of multi-image accumulation and multi-resolution background subtraction to detect mura defects in low-contrast and high-noised TFTLCD images. First, several images of an LCD on a moving product conveyer are contiguously captured and then a synthesized LCD image is used to calibrate the non-uniform illumination of these images. Second, the images are aligned in posit...
