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.
More often than not, with the purchase of a sports car comes the sacrifice of any sort of utility. In other words, you can forget about a large trunk, extra seats for the kids, and more importantly driving in snowy (or inclement) weather. But what if there was a vehicle that offered the best of both worlds; great handling and practicality?
Science fiction author Isaac Asimov may have the best rules for effective brainstorming and creativity. His never-before-published essay, "On Creativity," recently made it to the Web pages of MIT Technology Review.
Much has been made over the potentially dangerous flammability of lithium-ion batteries after major companies like Boeing, Sony, and Tesla have grappled with well-publicized battery fires. Researchers at Stanford University may have come up with a solution to this problem with a smart sensor for lithium-ion batteries that provides a warning if the battery is about to overheat or catch fire.
