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.
These new 3D-printing technologies and printers include some that are truly boundary-breaking: a sophisticated new sub-$10,000, 10-plus materials bioprinter, the first industrial-strength silicone 3D-printing service, and a clever twist on 3D printing and thermoforming for making high-quality realistic models.
Ear-based heart-rate monitoring gained momentum recently, as sensor maker Valencell Inc. announced it has licensed its biometric earpiece technology to Samsung Electronics Co. Ltd for use in so-called “hearable devices.”
