Field-induced 1D/2D switchable grating based on a polymer-dispersed liquid crystal.

This letter proposes a 1D/2D switchable grating that is fabricated by injecting a mixture of polymer and liquid crystal (LC) into a LC cell with in-plane switching (IPS) electrodes and using a photomask for polymer-induced phase separation. The switching between 1D and 2D gratings is achieved through an external electric field. In the absence of an external electric field, a 1D polymer dispersed LC (PDLC) grating is presented; under the presence of an external electric field, the PDLC grating couples with the IPS electrode to form a 2D grating.

Viewing angle controller based on dual hybrid alignment nematic cells for automotive co-driver displays.

We proposed a viewing angle controller (VAC) for automotive co-driver displays (CDDs). This VAC, integrated with the CDD, provides essential information to the co-driver while minimizing distractions for the driver. It consists of two hybrid alignment nematic (HAN) liquid crystal cells, two -C films, and two polarizers.

Viewing angle controller using two parallel alignment liquid crystal cells for automotive systems.

We proposed a viewing angle controller (VAC) for car co-driver displays (CDDs). This VAC, integrated with the co-driver display, provides necessary information to the co-driver while minimizing driver distraction. It comprises two parallel alignment liquid crystal cells and two negative C films.
