Liquid crystal displays are manufactured on flat rigid substrates where the liquid crystals position between pixel electrodes and counter-electrodes. Flat is important, because bending produces unequal distances between electrodes. This difference results in color irregularities. Omron Corp.'s Material Development Department (part of the Electronic Components Business Company) is challenging the production limitation. Using a vacuum impregnation technique, Omron has demonstrated the ability to insert liquid crystals into a polymer film consisting of approximately 0.5-micron diameter spherical polyacrylate particles. Because the polymer network is finer than than conventional self-supported polymer/liquid crystal composite film, it allows a uniform color across a display whether the display is bent or not. Other potential applications for this capability include light-diffusion film, reflection film, and ink jet printing paper. For further details, contact Christopher_udell@omron.co.jp.
A bold, gold, open-air coupe may not be the ticket to automotive nirvana for every consumer, but Lexus’ LF-C2 concept car certainly turned heads at the recent Los Angeles Auto Show. What’s more, it may provide a glimpse of the luxury automaker’s future.
The complexity of diesel engines means optimizing their performance requires a large amount of experimentation. Computational fluid dynamics (CFD) is a very useful and intuitive tool in this, and cold flow analysis using CFD is an ideal approach to study the flow characteristics without going into the details of chemical reactions occurring during the combustion.
