Response times in Pi‐cell liquid crystal displays

Abstract

The response times of Pi‐cell liquid crystal displays with an arbitrary pretilt angle were calculated under different drive methods. Using the normal drive method, the results show that the rise and off times of the cell driven by high voltage are faster than those driven by low voltage. However, the off time is very fast for the cell with non‐zero critical voltage driven by low voltage when we use the under‐shoot method.
