Their Trinitron picture tube was a universally well received technology and made a number of important improvements on the standard color picture tube. This is the story of its creation. **The trinitron CRT wasn't impervious to Moire patterns. However, it was less prone to them because of the lack of a phosphor grid. Vertical misalignment could still occur with the aperture grille, so moire patterns could still appear on patterns with strong vertical stripes. However, moire patterns wouldn't appear with horizontal image components due to the lack of distinct phosphor groupings. **The patent expired in 1996, not 1998.
