Zusammenfassung:The four‐point bending test, pure bending, is one kind of common test to evaluate LCD panel strength. From lots of four‐point bending experiments, we conclude that LCD panel strength is strongly correlated with manufacturing process. Also, St Venant flexure theory could not have properly analytical result to explain physical defect symptom of LCD panel after bending tests. This article aims at finding a numerical model to align both numerical and experimental results and obtains fracture stress under stabilized manufacturing condition.
