Samsung Display on Sept. 16 released a foldable OLED display panel with the world's smallest curvature of 1.4R for a smartphone.
The 1.4R rating refers to the curvature of a 1.4-mm radius circle. The smaller the figure, the more perfectly a device can be folded.
Samsung Display's breakthrough of the smallest OLED curvature on the market means a near-perfect fold for such smartphones.
This is Samsung's third foldable OLED panel and has a resolution of 2,208×1,768 pixels and a 7.6-inch screen, bigger than previous models.
The new display has received praise for its slim and sleek design thanks to the lower curvature rating of the folding area. It was first applied to the Galaxy Z Fold 2 of Samsung Electronics launched last month.
LG Electronics has also introduced a smartphone innovation through the LG Wing.
Released online on Sept. 14, the new model has a rotatable main display that enables multiple shapes.
The LG Wing can be used as an ordinary smartphone but when needed, the main screen can be moved clockwise to unveil the hidden 4-inch secondary screen that can be used with the main one. One app can run both screens or one app can be used for each screen.
Equipped with Gimbal Motion Camera for the first time in the world, the Wing allows more stable and gentle video shooting.
From next month, the model will be launched in Korea, North America and Europe in phases.

A TV that rolls up into a speaker when not in use and a robot that monitors the user's health and calls 911 in case of emergency. These were among the most exciting tech products unveiled on Jan. 7 by Samsung Electronics and LG Electronics at this year's Consumer Electronics Show (CES) in Las Vegas.
The world's first rollable OLED TV unveiled by LG has a screen that can appear and disappear from a rectangular base with the click of a remote control. The TV has traditionally belonged in the living room in front of the sofa but this new model is good anywhere within the home.
The base can be connected to a smartphone and used as speakers. Consumers can also set the screen into the base about three-quarters of the way for use as a clock or monitoring panel for other smart devices. This mode allows users to also look at photos or play videos.
Samsung also showcased its Robot Companions, or AI-powered automated helpers for the elderly designed to serve as digital nurses. Samsung Bot Care, which debuted at this year's CES, is a next-generation health aid that monitors vital signs like blood pressure and heart rate while keeping track of medication intake. It also sends a report based on a user’s health monitoring stats to family members and calls rescue services in the event of an emergency.
Future mobility products featured at CES 2019 included Elevate, a walking car developed by Hyundai Motor Company, and Hover Car, a flying two-seater by Volkswagen. The latest models of AI-powered speakers like the Amazon Echo and Google Home were showcased as well.
CES, along with the Mobile World Congress in Barcelona, Spain, and IFA (Internationale Funkausstellung) in Berlin, Germany, is considered one of the world’s three biggest tech events. To run from Jan. 8-11, CES 2019 will showcase more than 4,500 exhibiting companies from over 150 countries.
