FD Trinitron/WEGA is Sony's flat version of the Trinitron picture tube. First introduced in 1998 on Sony's 32-inch and 36-inch televisions, this technology was also used in computer monitors bearing the Trinitron mark. Flat CRTs reduce the amount of glare on the screen by reflecting much less ambient light than spherical or vertically flat CRTs. Flat screens also increase total image viewing angle and reduce overall geometric distortion.
