41.5L: Late‐News Paper: Novel Field‐induced Pre‐tilt Alignment Technique Using a Photo‐reactive Alignment Layer for VA LCD

We developed a novel LC alignment method for controlling molecular tilt angle by applying a field with photo—reactive polyimide as an alignment layer. This innovative technology establishes a high level VA-LCD whose characteristic is not only fast response time but also a lower black level even more high reliability.

Field-induced photo-reactive alignment technology for the vertical-alignment liquid-crystal mode

— An advanced vertical-alignment liquid-crystal (VA-LC) technology based on field-induced photo-reactive alignment (FPA) as an advanced alignment mode for VA is proposed. FPA realizes uniform alignment and a faster rising response time, especially at high voltage. This technology can generate a pre-tilt angle only by using photo-reactive alignment material so that the tact time is shorter and the long-term reliability is higher than that of conventional photo-reactive processes, which require additional photo-reactive monomers. The advanced hybrid FPA was developed by adopting both the tilted alignment with a pre-tilt angle and conventional vertical alignment. By using an advanced hybrid structure, the response time and contrast ratio can be further improved.

AnyLight: an integral illumination device

We introduce AnyLight, a novel programmable lighting device that can mimic the illumination effects of a broad range of light sources ---both real and imagined---using the principle of integral imaging. The flat, panel-shaped device functions in essence as a type of light field display, relying on custom, 3D printed optics to precisely control light rays emanating from each point on its surface, simulating the existence of arbitrary light sources concealed within the device, e.g., spotlight, candle, skylight, etc. A room illuminated with AnyLight would allow occupants to manipulate ambient lighting with a degree of freedom unreachable using existing programmable lighting setups, where typically color is the only adjustable parameter.

AnyLight: Programmable Ambient Illumination via Computational Light Fields

In this paper we describe AnyLight, a lighting device that uses computational light fields to offer highly programmable illumination for architectural environments. Relying on integral imaging--a technique commonly used to realize stereoscopic 3D displays--AnyLight can mimic the illumination effects of various light sources, both real and imagined. A combination of high-output, narrow-beam LED backlight and custom, 3D printed optics give the device the capacity to shoot out strong, targeted light rays from its surface in arbitrary directions. The paper will provide extensive discussions covering the devices technical details, usage scenarios, and possibilities for future extensions; quantitative and qualitative results from our initial evaluation sessions will be reported as well.
