Problems solved by technology

While the method has some advantages, some fabrication techniques (for example, fusion processes that result in rapid quenching of glass sheets from the melt and higher temperature structures) are "frozen"
While partially controlled cooling is possible with this manufacturing process, it is difficult to control

Embodiment

[0093] The following examples are set forth below to illustrate methods and results in accordance with the disclosed subject matter. These examples are not intended to be inclusive of all aspects of the subject matter disclosed herein, but are intended to illustrate representative methods and results. These examples are not intended to exclude equivalents and variations of the invention that would be apparent to those of ordinary skill in the art.

[0094] Efforts have been made to ensure accuracy with respect to numbers (eg, amounts, temperature, etc.), but some errors and deviations must be accounted for. Unless indicated otherwise, temperature is in °C or is at ambient temperature, and pressure is at or near atmospheric. The compositions themselves are given in mole % based on oxide and have been normalized to 100%. There are numerous variations and combinations of reaction conditions such as component concentrations, temperature, pressure and other reaction ranges and co...

Abstract

The invention relates to glass with improved total pitch stability. Described herein are alkali-free, boroalumino silicate glasses exhibiting desirable physical and chemical properties for use as substrates in flat panel display devices, such as, active matrix liquid crystal displays (AMLCDs) and active matrix organic light emitting diode displays (AMOLEDs). In accordance with certain of its aspects, the glasses possess excellent compaction and stress relaxation properties.
