Both types scan the display, one pixel at a time. Active matrix displays have a transistor associated with each pixel that keep the pixel turned on longer, it is in fact very similar to Dynamic RAM. Active matrix pixels are turned on for a longer percentage of the time, this is known as duty cycle. The higher the duty cycle the wider viewing angle and better overall image quality. Active matrix displays look much sharper and can be seen at a wider viewing angle. -- Clark Martin Redwood City, CA, USA Macintosh / Internet Consulting [EMAIL PROTECTED] "I'm a designated driver on the Information Super Highway" -- PowerBooks is sponsored by <http://lowendmac.com/> and...
