Subjective evaluation of motion picture quality on LCDs

摘要

We compared motion picture quality of LCD with that of CRT display. TN, IPS and STN LCD were tested by subjective evaluation. Two moving patterns were tested, one was the white rotating lice on the black background and the other was the checker pattern moving horizontally. The results showed that picture quality on the STN display was significantly worse than that on both TN and IPS display however, there was no significant difference in picture quality between TN and IPS LCD in most test conditions. Comparing to the CRT display there found significantly lower quality on all three LCDs, especially when the checker patterns moving horizontally.
