Study on Glass Strength at High Speed Edge Rounding for LCD

Abstract:

Article Preview

With increasing in size of glass substrates for flat panel, both high productivity and high quality are required for its edge rounding process. In order to understand the effect of process speed on the strength of glass substrate, this study performs a profile grinding at the substrate edge with varied feed rate. The obtained glass substrate then undergoes a four-point bending to evaluate its strength. Weibull distribution is used to analyze the fracture strength of glass substrate after edge-rounding process and to correlate the removal rate with the quality of the process.
