Impact of the Resolution on the Difference of Perceptual Video Quality Between CRT and LCD
The incoming of the high-definition new visual experience at home has boosted the new display technologies such as liquid crystal displays (LCD), plasma and projectors. These technologies enable the increase of the screen size necessary to sense a cinema-like experience. However, they introduce some new visual shortcomings not present with the mature CRT technology. In this paper, some subjective tests are described which highlight a difference of the perceptual video quality between CRT and LCD. Moreover, it's observed that this loss of quality on LCD is more important with high resolution sequences than with standard resolution ones. This influence of the resolution is particularly explainable in the case of the LCD motion blur defect.
