A method of reducing distortion in a glass sheet is described and comprises the steps of: forming a glass ribbon in a glass manufacturing process; separating a glass sheet from the glass ribbon, the glass sheet having a substantially flat surface; measuring a retardation through the surface of the glass sheet; defining a retardation parameter indicative of the retardation of the glass sheet; cutting the glass sheet into a plurality of sub-sheets; measuring a distortion of the sub-sheets; defining a distortion parameter indicative of the distortion of the sub-sheets; and determining a correlation between the retardation parameter and the distortion parameter such that the distortion parameter of sub-sheets of a subsequent glass sheet can be predicted based on the correlation.

Pastes for use in producing sintered frit patterns () on glass sheets (), such as the glass sheets used as covers for OLED () display devices (), are provided. The pastes include glass particles, filler particles, and a vehicle. The sizes of the filler and/or glass particles are reduced compared to prior art pastes. Reductions in porosity and surface roughness of sintered frits produced using the pastes, as well as improvements in the available process window for producing OLED packages and the hermeticity and strength of those packages, are reported.
