The new OLED panel developed by Korean researchers can be rolled up like a newspaper. The highlight is that it can remain highly efficient in spite of repeated bending. This means that the new flexible OLED technology can be used in varied wearable monitors. At present, flexible OLED technology can be found curved edges of TVs as well as smartphones. The researchers also succeeded in raising the display brightness by making the most of resonance within OLED. Resonance is an occurrence that displays a strong response to particular frequency windows and laser is a perfect example of resonance.
