LG Display unveiled a new mobile phone prototype that uses a 6" plastic-OLED display that is curved on two sides. LG Display calls this panel an "Active Bending" OLED, and it's currently just a prototype panel.
The 6" panel features a disappointing 1280x720 resolution (LGD is already producing 5.5" FHD flexible OLEDs). It is only 0.7 mm thick and can reach a brightness of 300 nits.
Samsung's Note Edge phone curves on just one side, but at CES Samsung Electronics reportedly privately demonstrated a dual-edge curved GS6 variant.
