Screens: LG shows transparent, foldable and flexible OLED displays


Like many events during the corona crisis, Displayweek 2020 also took place as an online event. LG showed new concepts and application scenarios for its OLED panels. For example, a 65-inch TV with 4K resolution can be built, which switches between a curved and a flat mode. The built-in panel of the prototype shown is convexly bendable. In addition to the curved display, other versions were shown, including folded, transparent and rolled displays.

LG has often presented the latter at trade fairs as a signature OLED display that can be rolled up like a canvas after use. However, the company also imagines other applications – such as a roll-up display in vehicles with a bending radius of one centimeter, which can be used as an entertainment system for passengers. LG also names screens on the dashboard, the center console, as a sun visor or in the roof of the vehicle.

Fold and see through

Foldable OLEDs are already used in smartphones such as the Samsung Galaxy Fold (test). LG presented a panel with a diagonal of 13.3 inches, a resolution of 1,536 x 2,048 pixels and a brightness of 300 cd / m². In addition, a pen digitizer is built into the panel, which makes it possible to use a stylus. In one concept, the company is showing a tablet that can be folded in the middle, the screen edges of which also arch around the case and can be used as a quick display for new messages.

The transparent OLED display measures 55 inches, supports touch operation, a resolution of 1,920 x 1,080 pixels and can be adjusted in terms of light transmission. LG shows the concept in a wardrobe, which can also be used as an information board with weather information, news and other functions. At IFA 2019, the Japanese competitor Panasonic also presented such a concept – initially as a television.
