Enhanced dynamic response of the in-plane switching liquid crystal display mode through polymer stabilization

Abstract: A significant improvement in the dynamic response time of the in-plane switching nematic liquid crystal mode, useful in flat-panel display applications, is achieved through polymer stabilization. This improvement is achieved by introducing a low-density, stabilizing polymer network that causes the nematic director to favor the zero-field orientation at the expense of transmission and slightly higher drive voltages. We present a simple model that treats the polymer network as an effective field in the general f… Show more

“…The nematic LC / polymer composite system has also been applied to a polymer stabilizing and polymer-sustained technologies to enhance the cell performance [19][20][21][22][23][24][25]. The RM of typically less than 5 wt% is dissolved in the LC to get the polymer stabilized effect.…”

“…This consists of a reorganization of the nematic director -initially aligned by the polymer network -by applying an external electric field producing changes in electric capacitance, optical transmission, light scattering, etc [3,[6][7][8]. Thus studies of formation and properties of liquid crystaldispersed network systems (LCDNS) are very timely, also for the next generation of LC displays [4,6]. In the past there have been several studies devoted to LCDNS, both experimental and theoretical [6][7][8], but so far the effect of such complex confinement was described only phenomenologically in terms of an effective field [6], while there have been virtually no investigations at the microscopic level [9].…”

In this Letter we investigate the field-induced changes of molecular ordering in LCDNS by means of Monte Carlo (MC) simulations, starting from a simple pairwise potential and giving great emphasis to the role of polymer network topography.…”

“…4 The model of the polymer matrix as a series of planes perpendicular to the x-, y-, and z-axes of the Cartesian coordinate system was introduced by Hikmet. 5 None of these models explicitly account for the observed dependence of the critical field on polymer concentration.…”

“…1 Thus, we assume that the polymer network has planar alignment identical to the alignment of the liquid crystal. 3,4 A schematic illustration of the experimental set up for measuring the transmission properties of a PSLC cell is shown in Figure 1(a). The cell is situated between a pair of parallel polarizers, with the nematic director oriented at 45 o to the transmission axes of the polarizers.…”
