Brief description of embodiments of a display panel comprising a slab has dimensional stability improved

摘要

A display panel production process involves dimensionally stabilizing a glass sheet by molten alkali metal salt treatment. A display panel production process involves immersing a glass sheet in a molten alkali metal (preferably potassium, sodium or lithium) salt at above 450 (preferably 460) deg C for more than 1 (preferably 8) hours to provide dimensional stability during heat treatment in an electrode, dielectric layer, spacer and/or barrier deposition operation.
