We describe Coliseum, a desktop system for immersive teleconferencing. Five cameras attached to a desktop LCD monitor are directed at a participant. View synthesis methods produce arbitrary-perspective renderings of the participant from these video streams, and transmit them to other participants. Combining these renderings in a shared synthetic environment gives the illusion of having remote p...

The progress in high technology has led to the wide use of thin film transistor-liquid crystal display (TFTLCD). The evolution of the manufacturing technology of TFT-LCD keeps increasing the size of TFT-LCD since a larger TFT-LCD allows a larger display application and an improved productivity. However, as the size of TFT-LCD increases, the size of TFT-array substrates and color filter substrat...

An autostereoscopic display with parallax barrier attached onto a liquid crystal panel suffers from the trade-off between brightness and crosstalk. One approach for making improvement by modifying the layout of light blocking components, such as thin film transistor, storage capacitor, and protrusion, in the liquid crystal pixel has been proposed. Ray tracing simulation shows that the aperture ...

A patterned polymer dispersed liquid crystal transparent display using one-time UV exposure is demonstrated. The device fabricated by exposing the cell with a uniform light through mask selective attenuation of light. voltage-transmittance response different for corresponding regions. Thus, three states total scattering, transparent, and can be realized controlling applied voltages. proposed us...

The term liquid crystal describes a fluid in which geometrical structure of individual molecules can induce a tendency to align in certain ways with other molecules or with external magnetic or electric fields or with container boundaries. The degree and nature of molecular alignment strongly influences the optical properties of the liquid crystal, a phenomenon that lies at the heart of the cur...

Liquid crystal photo-alignment using azo-dyes for display and photonics applications is discussed. Various types of the glass and plastic substrates are used. Special types of 3D LC alignment, LC alignment inside thin micro tubes, and LC cladding layers in Si based waveguides and grating surface are concerned. The azo-dye photoalignment of polymerized LC films used as optical elements, such as ...
