Psychometric Evaluation of Point Defects on TFT/LCD

Abstract

A psychophysical measurement on disturbance caused by point defect on TFT/LCD was carried out. The color and the brightess of a point defect as well as background were varied. In the experiment, subjects were asked to adjust the luminance of the reference stimulus so that the amount of disturbance by both stimuli becomes the same. The results were analyzed statistically and a multi-regression model using L*, u*, v* was proposed.
