Brightness
F P D s on average are brighter than CRTs. A CRT may have brightness of about 100 c a n d e la s/square meter, while a high-quality 15-inch FPD might be rated at 300 nits. This brightness disparity decreases a bit in larger sizes.

The ability to display a high-contrast image is an important aspect of image quality, particularly for text. An average CRT monitor ratio of 200:1 and An inexpensive F P D contrast ratio of 200:1.
3. Usability in bright environments
