There are two types of light emission by OLED: fluorescence and phosphorescence. Fluorescent organic materials have been used since the beginning of development, but phosphorescent organic ...

Efficiencies and lifetimes vary depending on the colour of the OLED emission. Lifetimes in particular vary with the brightness of the pixel, according to an approximately square power relationship ...

One issue in realizing practical flexible OLED displays is the durability of OLED devices. Thin film substrates are permeable to oxygen and water vapor in the air, so that using materials ...

A research team has developed the world's first smartphone-type OLED panel that can freely transform its shape while ...

In a direct emission OLED display, the red, green and blue subpixels each emit their own light. See WOLED. THIS DEFINITION IS FOR PERSONAL USE ONLY. All other reproduction requires permission.

This green material demonstrates a light emission efficiency of 25 cd A −1 and excellent colour coordinates (0.26, 0.65). Furthermore, a high-performing red solution OLED material developed by ...

POSTECH Unveils World’s First Dynamic Shape-Morphing Smartphone sized OLED Panel with Built-In Speaker — All While Maintaining Ultra-Thin Flexibility.

Previously, blue OLED technology was restricted to less efficient fluorescent emission tech, while red and green OLED could be manufactured with more efficient phosphorescence emission.

Sony has unveiled a groundbreaking display system, dubbed "New RGB LED," promising superior color reproduction than ...
