Electronic technology is a new technology developed in Europe, the United States and other western countries at the end of the 19th century and the beginning of the 20th century. The Telegraph was first invented by American Morse in 1837, the telephone was invented by American Alexander Bell in 1875, and the electronic tube was invented by British physicist Fleming in 1902. Electronic products have developed most rapidly and widely used in the 20th century, and have become an important symbol of the development of modern science and technology.

The first generation of electronic products take electronic tubes as the core. At the end of 1940s, the first semiconductor transistor was born in the world. With the characteristics of compact, lightweight, power saving and long life, it was quickly used by many countries and replaced the electronic tube in a large range. In the late 1950s, the first integrated circuit appeared in the world, which integrated many transistors and other electronic components on a single silicon chip, making electronic products more miniaturized. Integrated circuits have developed rapidly from small-scale integrated circuits to large-scale integrated circuits and ultra-large-scale integrated circuits, which makes electronic products develop in the direction of high efficiency, low consumption, high precision, high stability and intelligence.
