A few days ago we posted on Konica Minolta Pioneer OLED (KMPO) and its demonstration of simple flexible OLED lighting panels integrated into packaging. My friend Takatoshi Tsujimura, CTO at KMPO, sent me this nice Christmas greeting card, which arrived yesterday, with an integrated small red OLED. The OLED has a mirror finish when off.
This was exciting to get, and the whole card is very well done and feels great. It's a very nice surprise to see something light up in such a thin paper card. KMPO calls this concept "thin paper products with functionality".
