Mixed Field Controlled-Vertically Aligned Nematic Mode with High Transmittance

We propose a new LCD mode, mixed field controlled vertically aligned nematic (MFVA) mode to improve demerit of patterned vertically aligned nematic liquid crystal (PVA) mode that has lower transmittance due to flat electrical potential in vicinity of central region between top and bottom slits. The...

Description
Summary:We propose a new LCD mode, mixed field controlled vertically aligned nematic (MFVA) mode to improve demerit of patterned vertically aligned nematic liquid crystal (PVA) mode that has lower transmittance due to flat electrical potential in vicinity of central region between top and bottom slits. The proposed mode which produces higher transmittance and faster response speed than PVA mode is composed of the two stripe type ITO common electrodes, wholly ITO coated common electrode, and wholly ITO coated pixel electrode. The simulated results show that the proposed LCD mode has excellent electro-optical characteristics.
