Understanding `glass relaxation` and why it`s important for next-generation displays
(PHYSorg.com Physics)

Next-generation displays will feature increased resolution and performance, but getting there will require a shift to smaller individual pixel sizes and a tightening of the tolerance for glass relaxation. Display manufacturers can account for a certain level of relaxation in the glass, referring to the intermolecular rearrangement, if it`s known and reproducible. But fluctuations in this relaxation behavior tend to introduce uncertainty into the manufacturing process, possibly leading to misalignment of pixels within displays.
