“The semiconductors are known as quantum dots and are made from naturally occurring organic compounds called peptides, short chains of amino acids, the building blocks of proteins. In a demonstration, Mr. Rosenman shone a blue light (the backlight in an LCD TV is blue) onto tubes containing different solutions of quantum dots. The tubes lit up in red, green and blue—the constituents of any display. “There is a cost saving of about 10 times compared to other displays,” said Mr. Myersdorf. “The manufacturing process is the same as for making OLEDs.” An OLED is an organic light-emitting diode, commonly found in some smartphones and TVs.” via The Wall Street Journal
