48.2: Advanced VA Mode with Fast Gray Scale Response and Wide Viewing Angle in a Bend Liquid Crystal Configuration

We have developed “Transverse Bend Alignment (TBA) mode”, an advanced VA mode where liquid crystal materials are driven by a combination of a lateral field and a vertical field. We have made TFT-LCDs with different spacings of comb-shaped electrodes to reduce the steepness of the V-T characteristics. By adjusting cell parameters, the LCD has wide viewing angle without color wash-out in oblique directions and fast response between all gray scale levels.
