Organic light-emitting diodes (organic light-emitting diode, OLED) are also known as electromechanical laser displays, organic light-emitting semiconductors.
Dengqingyun (Ching W. Tang), a Chinese-American professor, was found in the laboratory in 1979. OLED display technology has the advantages of spontaneous light, wide viewing angle, almost infinite contrast, low power consumption and extremely high reaction speed. However, as a high-end display, the price will be more expensive than the LCD TV.
