Glass manufacturing method and apparatus

Abstract:

A glass manufacturing method. A plurality of stress values in a glass sheet are determined in a plurality of locations of the glass sheet respectively. A plurality of light leakage degrees are determined in the plurality of locations of a polarization-based display provided with the glass sheet, when the polarization-based display is in a state to block light transmissions. The plurality of determined stress values are modified based on the plurality of determined light leakage degrees. At least one additional glass sheet is manufactured in a glass sheet manufacturing process with at least one process condition of the glass sheet manufacturing process being adjusted based on the plurality of modified stress values.
