Key technologies for the τ-Vmin mode FLCDs (Ferroelectric Liquid Crystal Displays) were developed. An FLC material with negative dielectric anisotropy was developed, realizing fast line address time of 23µmicro;sec/line at 25˚C. The C2-uniform (C2U) orientation with chevron layer structure was achieved by using an aligning film with medium pretilt angle.(More)
In this research, we proposed a new image quality evaluation index Color Distribution Index (CDI). It considers color gamut, contrast ratio, maximum luminance, electro-optical characteristics such as gamma, bit depth and JND as human visual system to evaluate the ability for reproducing visually smooth gradation. When the CDI cell was defined, we verified(More)
