　　In 2007, the first generation of iPhone was released by Steve Jobs. Once launched, it amazed the world with its epoch-making touch screen and touch screen interactive technology.

　　Today we are talking about touch screens.

　　I bet you are seeing this article through the touch screen now, am I right?

　　Touch screens can be seen everywhere around us, covering fields such as communications and automobiles. It is simple, convenient and natural.

　　But, do you know when the touch screen appeared? How was it invented?

　　The history of touch screen can be traced back several decades, and the 1982 Knoxville Expo was the venue for the first public display of this technology.

　　Energy: the driving force of the world

　　In the 1970s, the United States experienced two oil crises, and the energy issue once became the focus of attention across the United States. Energy has changed the world, bringing new technology and a new industrial revolution. The holding of the World Expo has also changed the small city of Knoxville in the southern United States.

　　Looking back at the 1982 World Expo, Knoxville proved to the world that a small town relying on a valley was also capable of organizing such an event.

　　This is a typical American World Expo. Entertainment, food, carnival, shopping and curiosity were the favorite life content of Americans in the 1980s.

　　The most important significance of the Knoxville Expo is the choice of a far-reaching theme-Energy: the driving force of the world. Energy has changed the world, bringing new technology and a new industrial revolution. The holding of the World Expo has also changed the small city f Knoxville in the southern United States.

　　Accutouch

　　The 1982 professional exposition with the theme "Energy Changes the World" was the center of new digital technologies, but few people could have predicted that the Accutouch exhibited by George Samuel Hurts at the US Pavilion would be Success.

　　This invention is a touch-sensitive panel installed on a TV screen, which occupies a prominent place in the exhibition hall, encouraging visitors to try future technologies on one of the 33 available screens.

　　Accutouch is not the first touch-sensitive screen to be developed. Previous devices were designed using different types of technology in the UK in the 1960s. However, it was the "resistive" technology that was demonstrated at the 1982 World Expo: lower production costs and more practical, which has been further developed, making it widely adopted worldwide.

　　Touch screens appeared in human society earlier than we thought.

　　1960s: the first touch screen was born

　　The technical concept of touch control has been proposed in the 1940s. The first real touch screen was developed by Eric Arthur Johnson, an engineer of the Royal Radar Company, in 1965. Manufactured.

　　This is a clunky but refreshing screen. Under Johnson's design, there is even a magical effect: no matter where the finger is touched, the screen will shine there.

　　70s: Resistive touch screen was born

　　The inventor of the resistive touch screen is the American inventor Dr. G. Samuel Hurst.

　　Dr. G. Samuel Hurst

　　Professor Sam Hurst, who is a teacher at the University of Kentucky at the time, invented a resistive touch that uses pressure to change current transmission. Although the college that funded the project did not believe that this invention could stepping out of the laboratory for commercial production in a short time, Dr. Hurst believes that only through further improvements, the combination of this technology and the computer screen will replace the mouse as a more convenient way to control the computer.

　　After the 1980s: the promotion of touch screen

　　Since the 1980s, as the portability of computers has gradually improved, technology companies have seen business opportunities for the combination of touch screen and computer.

　　In the 1990s, the technology can realize multi-touch has become more and more mature. In 1993, IBM and the telephone company BellSouth jointly released the first mobile phone product Simon that combines a touch screen with a telephone.

　　The turning point came in 2005.

　　This year, Apple acquired FingerWorks, together with all its multi-touch patented technologies and products, and applied this technology to upcoming products.

　　In 2007, the first smartphone iPhone with full touch screen control came out. Steve Jobs showed people this compact and concise mobile phone, stylish body and user-friendly control interface design, especially from the left. The classic unlocking interface that swipes to the right has left a deep impression on people.

　　It is also from this year that touch screen has gradually entered and integrated into our lives, becoming an indispensable part.

　　By 2021, touch screen can no longer be considered a novelty, not only the mobile phones and tablets we use daily, but also we can see touch screens on the streets.
