Taiwan-based PMOLED maker Wisechip announced it is developing transparent and flexible PMOLED displays last year, and the company has presented new prototype displays in a trade show in Germany last week.
Wisechip demonstrated three flexible OLEDs - a 1.8" 160x32 panel and a 1.36" 128x16 panel. Both are monochrome (white) panels as you can see in the photo above. The third display is a 256x64 one. The curvature radius of Wisechip's displays is 40 mm. The photo also includes a demonstration of a PMOLED display embedded in a credit card form.
