Another note regarding the background gray level needed for the indexing to work. Plasma panels had a similar problem at first, but ways were found to reduce the unwanted "fog" as time went by. It's quite possible that Indextron design could eventually have been improved incrementally to a point where it was acceptable compared to a shadow mask CRT too, but it died before enough effort could be concentrated on it.
