In this paper, we introduce color washout-free liquid crystal display (LCD) with thin layered color filter (CF) technique. The thickness of 1.5 thin layered CF was achieved by optimizing the performance of color resist. Thin layered CF can reduce color differences (ǻu'v') for RGB displays in oblique viewing angles, which means reduced color mixing.

In this paper, we propose new dye colorants of color-filter resister to increase color gamut area based on the new LED Backlight. The new dye materials showed good performance to enhance color gamut and transmittance in display. Also, it was verified that dye materials for color-filter resister have the excellent reliabilities and advantages in real panel test conditions. As well as color gamut increases from sRGB 100% to sRGB 145% with new LED Backlight.

Color characteristic degradation of color filter photoresist is occurred under high temperature, high humidity, and strong light environments. The effect of dispersant in color filter photoresist to color characteristic degradation was studied, and it depends on the dispersant in color PR, which has been experimentally verified.

In this research we study the motion of a defect in a homeotropic liquid crystal director with an inhomogeneous patterned electrode by using the fast Q tensor method, which can calculate the order parameter S in addition to the director orientation. An inhomogeneous solid surface with a step function is applied for modelling. The simulation includes defect nucleation, motions on the inhomogeneous surface, and the dependence of defect behavior on the shape of the electrode. In addition, we calculate the defect motion in the homeotropic in-plane switching liquid crystal cell. We believe that the calculated results using the fast Q-tensor method can provide a basic design rule of the electrode for better optical performance.
