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 Universal Display Corporation and the U.S. Air Force. The researchers added their new lights nearly meet the most stringent requirements of the National Television Systems Committee (NTSC), the video standards used across most of the Americas.

    It's simple. The air force does their work in the air. The sky is made out of air. The sky is blue. Hence, blue LEDs. Q.E.D.

    Active camouflage is what you are describing.
