Non-uniformity evaluation of flat panel display by automatic optical detection

The paper is focused on an 8k resolution on large panel generation in TFT-LCDs to detect its appearance, especially green color is the most sensitivity in human vision as well as ten million pixels resolution in the display. The experiment utilizes the machine vision associated with reflective chromaticity spectrometer to quantize the defects of the blackening and whitening onto green layer. A scientific quantization identifies the chromaticity to CIE xyY 0.001 and is foreseeable to just noticeable difference (JND) even beyond 0.3.
