VA-IPS Simulation

Nematic liquid crystals are physically described as the same energy in the n and -n directions but have different energy states in the vector model. When simulating the LC modes which occur topologically discontinuous phase transitions such as pi-cell, OCB, and VA-IPS, the Tensor Model function should be performed by assuming n and -n directions of LC cells are the same.

Guest-Host Simulation

The movement of dichroic dye molecules is dependent on the polarization of the incident light.
Guest-host devices are being extensively researched in various fields of displays including transparent displays and smart windows.

PBS Simulation

LCOS is a sandwich-like structure that contains LC cells between silicon backplane and cover glass.
The PBS function should be selected to obtain the results considering the changing status of the polarized light because there are a reflector, a quarter-wave plate, and multiple beam splitters on the inner side of LCOS in general.

2D LC Lens Simulation

LC lens has been considered as a promising field of research in optical systems by the advantages of small size and variable focus.
It’s possible to vary the focal length within a limited space since the refractive index of LC materials can be tuned by the application of a voltage. In the LC lens structure, calculation of optical path difference and focal length, and advanced LC analysis including LC director distribution by applied voltage can be performed through TechWiz Ray 2D and 3D.

LCOS Simulation

LCOS has a lot of advantages such as high resolution because it uses silicon backplane. However, texture patterns are formed due to the interaction between electric fields with adjacent cells in reflective LCOS. Engineers have to design the cell carefully to improve the transmittance.

3D Display Simulation

3D glasses can be classified as polarized and shutter glasses types that are widely used in the 3D display industry. 3D display with polarizer which polarizes the light differently for the left and right eyes and compatible polarized 3D glasses should be required to provide depth perception to the observer as three-dimensional images. From a viewing experience point of view, crosstalk may occur through the process of perceiving 3D images. The simulation by the viewing angles should be considered for designing 3D displays to get the correct solution.

Flexoelectric Efffect Simulation

Non-uniformity of voltage distribution in positive and negative frames induced by flexoelectric effect causes residual voltage and image-flickering. To overcome the image-quality under the flexoelectric effect, panel design and defect analysis can be performed by specifying particular splay and bend flexoelectric coefficients (𝑒_𝑠 𝑎𝑛𝑑 𝑒_𝑏).
