Everdisplay recently also unveiled a 5.6" WQHD (2560x1440, 525 PPI) flexible OLED prototype. Everdisplay started mass producing 5" 720p AMOLED displays towards the end of 2014. Since then the company seems to be accelerating its OLED program, and besides the new transparent and flexible prototypes, we know it is developing larger displays (5.5", 6" and an 8" AMOLED for the automobile market), round AMOLEDs (a 1.4" 400x400 circular AMOLED for the wearable market) and high density (734 PPI) AMOLEDs.

It seems that transparent OLED displays are finally being seriously developed by display makers. Samsung Display has been playing around with transparent OLEDs for a long time, and lately the company unveiled large-size (55") mirror and transparent OLED display panels, with plans to mass produce these by the end of 2015. According to reports, they are also thinking about starting to make transparent OLEDs in smaller sizes, with an aim to use these in home appliances such as refrigerators.

LGD is also developing large sized flexible and transparent OLEDs, and the plan is to produce such displays by 2017.
