Korean scientists announced Monday they have developed a new kind of highly efficient light emitting diode (LED) that can help develop next-generation displays and computer chips. The research team of Seoul National University said they have perfected a new production method that can produce high-quality green quantum dot LEDs with superior brightness and purity characteristics that are easier to make than existing products. The development was published in the latest edition of "Advanced Materials," and was featured in the April 22 issue of "Asia Materials."
