Paper Abstract

Liquid-crystal-displays (LCDs) and cathode-ray-tubes (CRTs) are compared with regard to color-calibration and color gamut. Applicability of common display calibration models to LCDs and CRTs is experimentally tested. Color-calibration accuracy, ease of calibration, and achievable color gamut are evaluated for the displays. An offset, matrix, and tone-response correction model is found to be suitable for color calibration of LCDs for most applications. The model, however, results in larger calibration error for LCDs than for CRTs, and unlike CRTs a power law tone-response correction is unsuitable for LCDs. A very significant color variation is seen with change in viewing angle for the prototype LCD display employed in the study. The LCD display provides a significantly larger color gamut under typical viewing conditions than CRTs, primarily due to higher luminance.
