Off‐axis image quality of a mobile PVA (mPVA) LCD has been improved by active level‐shifting technology and optimization of pixel and polarizer structures. The measured gray distortion index is reduced to 0.25, compared to 0.51 for a conventional mPVA LCD, resulting in decreased color shift at off‐axis viewing positions.
