Touch Panel

In 1948, the Electronic Sackbut completed by Hugh Le Caine is considered the world's first touch-sensitive music synthesizer, laying the foundation for the development of touch technology.

In 1965, E.A. Johnson of the Royal Radar Research Institute of the United Kingdom first proposed the concept of touch screen in his paper, and two years later he made the first capacitive touch screen in human history, a bulky composite glass screen with ITO metal oxide coated on the inner surface and four electrodes at the four corners.

In 1971, Dr. Samuel Hurst of the United States invented the resistive touch screen.

In 1972, the Plato IV terminal at the University of Illinois was equipped with an infrared touch panel for students to answer questions in class. This was the first touch screen device that was widely known and used in classrooms.

In 1982, Joseph Harman of the United States invented a resistive sensor for touch screens, which made touch screens more widely used.

In 1984, Bob Boie of Bell Labs developed the first multi-touch screen.

In 1993, Fujitsu of Japan launched the first commercial capacitive touch screen product.

In the same year, Apple used a resistive touch screen for the first time on the Newton MessagePad.

In 1994, IBM's pressure screen mobile phone Simon Communicator came out, which was the world's first touch screen mobile phone.

In 2003, the three founders of the French company Jazzmutant developed a multi-touch screen that can track any number of fingers, and in 2005 launched the music controller Lemur with this screen, which was the first transparent multi-touch screen technology product available to consumers.

In 2007, Apple launched the first generation of iPhone, equipped with a multi-touch screen, leading the trend of smartphones.

In 2010, Apple launched the iPad, introducing touch screen technology into the tablet computer field, further promoting the popularization of touch panels.

In recent years, touch panel technology has been continuously innovating, and new technologies such as flexible touch panels and pressure-sensitive touch screens have emerged. The scope of application has also been expanding. In addition to smartphones and tablets, it is also widely used in automotive displays, industrial equipment, public information equipment and other fields.
