New Technologies and Products

In addition to the mainstream twisted nematic, vertical alignment, and in-plane switching liquid crystal display modes, there are other molecular-level orientation structures, such as the liquid crystal polymer composite, the cholesteric nematic bistable, the ferroelectric chiral smectic-C, and the blue phase, as well as a cousin to the liquid crystals, the electrophoretic liquid suspension display. Another major display mode is the organic light-emitting diode (OLED), which is an emission display rather than a transmissive or reflective display, and thus fundamentally different from liquid crystal displays. These display modes are suitable for small portable devices, such as mobile smart phones, GPS navigation systems, tablets, e-readers, mid-size flexible displays, and large-size optical shutters for advertising displays and privacy windows. Also, other than the direct-view transmissive display, particularly for handheld and near-eye displays, there are the reflective and transflective displays, and for large-screen applications, the projection display. The functionality and attractiveness of the different display modes are further enhanced by brightness enhancers, touchscreen user interfaces, and the thrilling 3D display.

Following are very brief descriptions of the technologies and products listed above, meant only for an introduction to the subjects; the reader is encouraged to delve further by accessing the references noted.
