Detail All The Way to the Edge – A pure flat tube displays everything with amazing accuracy. Squares are really square, circles appear circular and straight lines are actually straight. Pure flat tubes deliver outstanding image detail, not only at the screen centre, but all the way to the edges; Wide Viewing Angle – Approach the side of a TV and you’ll really appreciate the difference a pure flat tube makes. As you walk towards a conventional TV, the screen bulge tends to block part of the picture. However, you can view a pure flat tube through almost a full 180-degree angle–without losing any picture; WEGA – the first flat screen TV in the world. For decades, many have tried to create a pure flat tube but someone had to be first to actually do it. First to overcome the enormous obstacles. First to solve the riddles. First to make a television picture tube with a flat screen. That someone was Sony. The Sony KVEF29M31 Sony’s first Flat Screen FD Trinitron TV was launched in 1997 to coincide with the 100 year anniversary of the Cathode Ray Tube (CRT).
