APPARATUS FOR TESTING DISPLAY DEVICE AND DISPLAY DEVICE FOR PERFORMING MURA COMPENSATION AND MURA COMPENSATION METHOD

摘要

The inspection apparatus for inspecting the display device detects a speckle region based on a detected image signal, a speckle detection filter that outputs location information of the speckle region and a filtered detection image signal, and applies the filtered image signal based on the location information. an image enhancement processor for performing deblurring of the image signal and outputting a deblurred image signal, a spot corrector generating first compensation data for the speckle area based on the deblurred image signal, and based on the detected image signal and a sampling compensator for generating second compensation data for the non-stained region, and a final compensator for receiving the first compensation data and the second compensation data, and outputting compensation data.
