For most of the analog television era, Sony was the virtually undisputed king of television. Their Trinitron CRT was widely praised for making a number of important improvements to the standard color CRT. ** The Trinitron CRT was not immune to moiré patterns, but was less susceptible to them due to the lack of a phosphor grid. The aperture grid still has a vertical offset, so moiré patterns may appear on patterns with sharp vertical stripes. However, moiré patterns will not appear on horizontal components of the image due to the lack of sharp phosphor groupings. **The patent expired in 1996, not 1998.
