Bright Blue PHOLEDs Almost Ready for TV: Deep blue lights could make smartphones, flat panel displays more ene...

A new energy-efficient organic LED (OLED) that glows a deep blue is finally close to meeting the most stringent U.S. video display brightness requirements, researchers say. OLEDs have enabled a new generation of bright, high-quality, low-cost, power-efficient, flexible, lightweight flat panel displays. Each pixel in an OLED display typically consists of red, green, and blue OLEDs that shine with different brightnesses to produce any desired color. Phosphorescent OLEDs (PHOLEDs ) use only one quarter the energy of conventional OLEDs. Green and red PHOLEDs are already used in smartphones and TVs, leading to longer battery lives and lower electricity bills, but developing the kind of bright deep blue PHOLEDs needed for video displays has proven challenging. Now scientists have developed what they say are the brightest deep blue PHOLEDs reported so far, work sponsored by Unive...
