P-124: Effect of Curvature Profile on Light Leakage of VA Curved LCDs

Light leakage was observed evidently when the panel was bent following the uniform circular arc curvature profile due to the residual stress. By simulation and experiment, we found that the curved panel stress and leakage can be significantly minimized when the uniform profile was modified into the...

Description
Summary:Light leakage was observed evidently when the panel was bent following the uniform circular arc curvature profile due to the residual stress. By simulation and experiment, we found that the curved panel stress and leakage can be significantly minimized when the uniform profile was modified into the un‐uniform profile, which is meaningful to guide the curved LCDs design and manufacture.
