LG Display announces it is mass producing 1.3" circular plastic-based flexible OLEDs

A few days ago LG Electronics launched the beautiful G Watch R smartwatch, with its 1.3" (320x320) flexible plastic-based OLED panel. Today LG Display announced that it started mass producing those OLED panels.

While it was pretty clear that LGD is behind this flexible OLED, it's good to hear a formal confirmation. LG Display further tells us that the panel is less than 0.6 mm thick and features a 100% color gamut (not sure which standard is that), 300 nit peak luminance and of course an "unlimited" contrast ratio.

The display module includes a special Power Save Mode (PSM) which is aimed towards wearable devices - allowing them to be turned on at all times with a "static" image while using less power (I'm not sure how this works, though).

To produce this circular plastic-OLED display, LG Display developed a special circular mask for the organic materials vacuum deposition process - and this mask enables the organic materials to be deposited simultaneously (?). LGD's new production process improves deposition efficiency while employing a highly precise laser cutting and processing technology.


Besides the round display, the G Watch R features the Android Wear OS, a 1.2 Ghz Snapdragon 400 CPU, 512MB of RAM and 4GB of storage. It has a 410 mAh battery which should last about a single day.
