Abstract

IPS and VA have evolved in various structures such as H-IPS, AS-IPS, and S-PVA gain more competitiveness. The new pixel structures inherently have more domains which cause disclination areas. The effect of disclination is no longer neglected in those structures. A new simulation tool based on FAST Q-tensor method enables one to predict the shape of disclinations and the resulting optical properties. It ensures more accurate results compared to vector-based simulation. We applied this simulation tool for the development of 26-inch wide monitor having H-IPS mode.
