New Jersey-based Universal Display and LG are showcasing a futuristic OLED display that can be worn like a wrist watch at the SID Display Week 2009. The bendable color display has been jointly developed by the two companies.
The futuristic OLED bracelet has a 4-inch display with a 100ppi resolution/QVGA (320 x RGB x 240 pixels), shows 1.67 million colors and features a luminance of 100cd/m2. Weighing 8g, the panel is just 0.3mm thick (as thin as an OLED screen Sony showed last year). 
This is certainly a cool prototype (just like Samsung’s much larger and thinner “flapping display”), but it’s just a prototype and it seems we have to wait a few more years before we can lay our hands on large-sized OLEDs.
