We propose a new light direction controlling backlight for nonglasses field sequential stereoscopic LCD. This backlight using a double‐sided prism sheet can change the direction of light by switching the light sources. We made a prototype, and demonstrated that the light from the backlight could be separated into the required directions

15-in. XGA TFT-LCD with fast response time is developed. The response time between grayscale transitions is reduced to less than 20ms by adopting newly developed Feedforward Driving (FFD) technology. High brightness, high color saturation, and wide viewing angle characteristics are also achieved, which are significant for multimedia applications.

Molecular orientation of nematic microdroplets in polymer-dispersed liquid crystal (PDLC) films has been investigated by time-resolved FT-IR (TR/FT-IR) in the presence of an applied electric field. Two kinds (fast and slow) of reorientation processes are found, and these may be attributed to reorientation of liquid crystal molecules at the surface and the central region of droplets. In addition, an induction time has been observed before the onset of the actual reorientation. It is suggested that there are no essential differences between rigid and flexible molecular segments with respect to reorientation dynamics of at least 1 ms time resolution. TR and micro-FT-IR techniques have been combined in order to study the reorientation dynamics of the different regions of droplets.
