Competing display technologies for the best image performance

摘要

Cathode-ray tubes (CRTs) have been the dominant display technology for years, having the best image performance and low cost. During the last several years, flat-panel-dis-play technologies, such as liquid-crystal displays (LCDs), began to replace the CRT mainly because of its favorable form factor. Today, the image performance of LCDs are equal to that of a CRT, and attractive flat-display products have become so affordable that they have replaced the CRT from its dominating market position and have obtained the largest market share. In the past, the CRT set the standards for digital imaging technologies, but today, modern image capturing, storage, transport, signal processing, and printing technologies have improved to such high levels that they demand better display technologies and standards. At present, the LCD is at the forefront of this display-technology evolution. This paper will focus on the latest image-quality improvements in LCD technology and briefly touch alternatives such as plasma-display panels (PDPs) and microdisplay projection. Special attention will be given to the latest developments in wide-color-gamut technologies and methods to reproduce accurate colors within a display device.
