“…Today, liquid crystal displays (LCDs) are widely prevalent because of the flat-panel type display, low weight, and low power consumption requirements. However, there are still some unsolved problems on LCDs [22]. For example, an image-sticking [23] occurs when a residual image is displayed as a result of continuous display of the same image for long periods of time.…”

In this review, we introduce a variety of surface sensitive techniques for the study of organic thin films, and applications to organic devices. These studies include surface plasmon emission light, organic thin film transistors, combination of quartz crystal microbalance and optical waveguide spectroscopy, evaluation of alignment of liquid crystal molecules at surfaces, and biosensor applications.

“…18 Afterwards, many efforts were devoted to explore the physical mechanisms behind the adsorption and desorption processes, both experimentally and theoretically. [19][20][21][22][23][24] Recently, based on Yasuda's model Mizusaki et al 24 proposed a more comprehensive kinetic model to evaluate the ion adsorption and desorption processes in homogeneous LC cells. This model is based on the assumption that ion adsorption is uniform over the entire interface under uniform longitudinal electric field, thus it does not apply to FFS or IPS cell, in which the electric field is in lateral direction and the field distribution is not uniform.…”

We propose a kinetic model to account for the nonuniform adsorption and desorption processes in fringe field switching (FFS) and in-plane-switching liquid crystal displays. An equation is proposed to describe the generation mechanism of residual DC voltage and good agreements with experiment are obtained. Based on this model, the mechanisms underlying the formation and relaxation processes of residual DC voltage as well as their dependences on offset DC voltage and temperature are investigated. Moreover, the residual DC voltages of FFS cells employing positive and negative dielectric anisotropy LCs are compared and the physics responsible for the observed difference is explained.

“…It was proposed for applications in displays as well as in other liquid-crystal optical devices, e.g., modulators and attenuators. [8][9][10][11] The role of the flexoelectricity in the stability of the hybrid aligned flexoelectric nematic (HAFN) layer subjected to an electric field was analyzed theoretically 12 and numerically. 13 It was shown that three different states can be stable under hybrid boundary conditions, namely, uniform planar, uniform homeotropic, and non-uniform which is intermediate between the former two.…”
