LG Develops Better Material for Foldable Displays

-
LG Chem has developed a new top layer for flexible displays that it claims is both "hard as glass" and "flexible as plastic", while offering several key advantages over materials currently used in folding displays. LG calls the new material Real Folding Window. Compared to existing materials, Real Folding Window should offer "significantly improved fold lines in the folding area", meaning less-visible creases. The material is also designed for both inward- and outward-folding displays, unlike current commercial products that are optimized for inward-folding displays. The mew material is thinner than tempered glass and cheaper than existing polyimide film products. LG's new material consists of a thin, proprietary coating on both sides of a thin PET (plastic) film. LG plans to begin "full-scale" sales of Real Folding Window from 2023. The company is already working on an improved version that removes the need for a PET base layer, which will be even thinner and better-suited to "rollable" displays.

Google Optimizes Android so Apps Take Up Less Space

Google has released a new version of the Android Runtime (ART), a core component that turns app code into lower-level code that can run directly on that specific device. The update contains new optimizations that reduce the resulting code size by about 9.3%. This means most apps now take up less space in both storage and RAM. On the average Android phone, this means a savings of about 50–100 MB in storage. Thanks to Google's modular design of the Android architecture, the ART update does not require a full OS update. http://dlvr.it/Sz0yKl

Xiaomi's Mi Mix Fold is First Phone with a Liquid Lens

-

Xiaomi today announced its first foldable phone, the Mi Mix Fold. The phone is also the first in the world to use Liquid Lens technology on one of its cameras. The Liquid Lens consists of transparent fluid wrapped in film. The radius of curvature of the spherical surface can be accurately changed thanks to a high-precision motor. This enables one 8 megapixel camera to serve as both a 3x optical zoom telephoto camera as well as a macro camera that can focus at a distance of 3cm. Philips first announced liquid lenses for phones in 2004, followed by Varioptic in 2006. Varioptic and partner Seiko even announced manufacturing ramp-up of two specific models of liquid lenses designed for phones in 2008. But none of these made it to shipping phones at the time. Those early designs used electric current to bend the liquid, which differs from Xiaomi's more mechanical approach. The Mi Mix Fold sports a design very similar to Samsung's Galaxy Fold and Z Fold2, with a tablet-size flexible s...
