38.4L: Late‐News Paper: A New Vertical Alignment Mode for TFT‐LCDs

A simple and cost-effective vertical alignment mode, named Smart Viewing Angle(SVA) mode, for active-matrix (AM) LCDs was developed where all the domain dividers are fabricated only on the TFT substrate side. The crucial component is the director control electrode (DCE) under the openings of the pixel electrode. The DCE maintains higher voltage than that of the pixel electrode via additional TFTs, which distorts the electric field in such a way that stable domain division is accomplished. Compared to the conventional VA modes where the additional process is required, SVA mode can achieve the wide viewing angle without any additional processes.
