Blue LED won the Nobel Prize and caused dissatisfaction: the efforts of early scientists should not be erased

Three Japanese scientists won the Nobel Prize in Physics the day before for their blue light-emitting diode (LED) technology. However, this news caused dissatisfaction with a technology founder in the LED industry.
According to a report in Hong Kong's "Wen Wei Po" on October 9, before the advent of blue LEDs, scientists had already developed red LEDs, which became the basis for all LED technologies. The 85-year-old American physicist Holenyak, who invented the red LED in 1962, is indignant at the latest announcement of the Nobel Prize in Physics, and believes that the blue LED award "insults" all scientists involved in early research on LEDs.
Holonyak, known as the "Father of LED," said that he and other scientists laid the cornerstone for blue-light LEDs in the 1960s and should not be ignored or forgotten. "Blue LED? It wouldn't have happened without us," he said.
According to reports, for more than 10 years, Holenyak has been regarded by his colleagues as one of the favorites for the Nobel Prize. However, after waiting for many years, he has long since given up the idea of ​​winning the prize. He believes that the entire LED technology cannot be divided. While the world recognizes later inventions, it should not deny the efforts of early scientists.
