FD Trinitron

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.

There were four primary variants of the FD Trinitron as used in televisions.

Super Fine Pitch refers to Sony's line of Trinitrons with high horizontal resolution and very fine aperture grille stripe pitch. By the end of CRT's market dominance, only Sony and JVC had released such high-resolution CRT HDTVs to the non-professional consumer market.

Hi-Scan is Sony's trademark for all Trinitron displays capable of processing a 1080i signal. Super Fine Pitch tubes naturally fall into this category, as do some Sony Trinitron SDTVs that cannot physically resolve 1080 lines of vertical resolution, but the term Hi-Scan is commonly used to refer to Sony Trinitron HDTVs that do not feature an SFP tube.

16:9 Enhanced WEGA models differ from original WEGA models mainly in their ability to display anamorphic video content in its proper screen aspect ratio. This is not a distinction of the tube itself; this capability is a function of the display circuitry in compatible television sets.

FD Trinitron CRTs were available in several screen aspect ratios. 4:3 and 16:9 were used on the WEGA line of televisions. Many 4:3 monitors were produced as well as several models using an aspect ratio of 16:10 (such as the GDM-W900 and GDM-FW900).

Competitors included Mitsubishi with their Diamondtron NF brand of flat aperture grille CRT displays, as used in certain computer monitors from Mitsubishi, NEC, and Apple.
