In-Plane Switching of a Liquid Crystal Cell
Application ID: 118771
This model demonstrates the switching capability of a liquid crystal (LC) display cell in In-Plane Switching (IPS) configuration.
The Oseen-Frank model is used to solve for the LC director (optical axis) distribution when a static electric field is applied. A Weak Form PDE interface is used to define the Oseen-Frank weak equation, whereas the Electrostatics interface is used to solve the electric potential distribution.
For the given inhomogeneous anisotropic LC material, a full-wave simulation is performed using the Electromagnetic Waves, Frequency Domain interface. The results show that the cell exhibits a large dynamic range in transmission, when the polarizer and analyzer are orthogonally oriented.
This model example illustrates applications of this type that would nominally be built using the following products:
however, additional products may be required to completely define and model it. Furthermore, this example may also be defined and modeled using components from the following product combinations:
The combination of COMSOL® products required to model your application depends on several factors and may include boundary conditions, material properties, physics interfaces, and part libraries. Particular functionality may be common to several products. To determine the right combination of products for your modeling needs, review the Specification Chart and make use of a free evaluation license. The COMSOL Sales and Support teams are available for answering any questions you may have regarding this.
