One year ago, researchers from the Korea-based ETRI (Electronics and Telecommunications Research Institute) demonstrated an 370x470 mm OLED array that use graphene transparent electrodes.

At this year's SID DisplayWeek trade show, ETRI researchers will demonstrate a flexible OLED panel that use a transparent graphene electrode. The researchers developed a "fully operational" 40x40 mm OLED panel that uses a pixelated graphene film as electrodes.
