Status of TFTLCD color and metrology

The changes in TFTLCD color with pixel level and with viewing angle are critical issues, which need to be understood for TFTLCDs to gain acceptance for color-intensive applications in the marketplace. The latest wide-viewing angle technologies have adequate color performance for most applications, yet far from ideal. These developments, when combined with the high pixel density, high local contrast ratio, and lack of distortion achievable with TFTLCD technology, will lead to displays with image quality superior in many ways to both CRTs and print. As TFTLCD image quality improves, many challenges remain for meaningful characterization, especially to compare image quality to other media.
