Introduction
Smartphone touchscreens are a ubiquitous part of modern life. We use them every day to access information, communicate, and entertain ourselves. But who invented this revolutionary technology? It’s a question that has many answers, depending on who you ask. In this article, we’ll explore the history of smartphone touchscreens, from the first concept to the present day. We’ll also look at the people behind the development of the touchscreen, from Eric A. Johnson to John F. Elias.
A Historical Timeline of Smartphone Touchscreens: Who Invented This Revolutionary Technology?
The concept of the touchscreen dates back to the mid-1960s, when Eric A. Johnson invented the first capacitive touchscreen. Johnson was an engineer at Royal Radar Establishment in Malvern, England. He developed the touchscreen as an alternative to the traditional keyboard and mouse. His invention used capacitors to sense when a finger touched the screen, which allowed users to interact with a computer without a physical input device.
Johnson’s invention was the foundation for the development of the smartphone touchscreen. Over the next few decades, numerous innovators worked to refine the technology, including John F. Elias. Elias was a researcher at the University of Delaware and developed the first resistive touchscreen in 1982. His invention used a pressure-sensitive material that allowed users to interact with the screen by pressing down on it. This technology was later adapted for use in consumer electronics, such as smartphones and tablets.
The Pioneers Behind the Revolutionary Technology of Smartphone Touchscreens
Eric A. Johnson and John F. Elias are two of the most important figures in the history of the touchscreen. They both made significant contributions to the development of the technology, but there were many other innovators involved in the process. These include researchers from universities and companies around the world, as well as scientists and engineers from various fields.
A Profile of the Innovators Who Brought Us Smartphone Touchscreens
Eric A. Johnson
Eric A. Johnson is credited with inventing the first capacitive touchscreen. Born in 1927, Johnson was an engineer at the Royal Radar Establishment in Malvern, England. He studied electrical engineering and physics at the University of Birmingham, where he earned his PhD in 1964. In 1965, Johnson developed the first capacitive touchscreen, which used capacitors to sense when a finger touched the screen. His invention laid the groundwork for the development of the smartphone touchscreen.
John F. Elias
John F. Elias is best known for inventing the first resistive touchscreen. He was born in 1946 and studied electrical engineering at the University of Delaware, where he earned his PhD in 1981. In 1982, Elias developed the first resistive touchscreen, which used a pressure-sensitive material that allowed users to interact with the screen by pressing down on it. His invention was later adapted for use in consumer electronics, such as smartphones and tablets.
Other Innovators Involved in Developing the Touchscreen
In addition to Johnson and Elias, there were many other innovators involved in the development of the touchscreen. These include researchers from universities and companies around the world, as well as scientists and engineers from various fields. Some of the most notable innovators include Andrew H. Van Dam, who invented the first graphical user interface; David Y.G. Lee, who developed the first commercial touchscreen device; and Peter J. Hughes, who created the first touch-sensitive display.
A Closer Look at the Invention of the Smartphone Touchscreen
The invention of the smartphone touchscreen was a complex process that involved many different people and technologies. The initial concept of a touchscreen was developed by Eric A. Johnson in 1965. He used capacitors to sense when a finger touched the screen, allowing users to interact with a computer without a physical input device. John F. Elias then developed the first resistive touchscreen in 1982, which used a pressure-sensitive material that allowed users to interact with the screen by pressing down on it.
The development of the touchscreen also involved the filing of several patents and licensing agreements. For instance, Andrew H. Van Dam was granted a patent for his graphical user interface in 1983. And in 1988, Apple licensed the touchscreen technology from Elographics for use in its Newton PDA. These patents and licensing agreements paved the way for the development of the modern smartphone touchscreen.
Taking a Deeper Dive into the History of Smartphone Touchscreens
The early years of the touchscreen saw slow but steady progress. In the 1980s, the technology was primarily used in industrial applications, such as ATMs and medical equipment. It wasn’t until the late 1990s that the technology began to be adopted by consumers. This coincided with the development of more advanced mobile devices, such as PDAs and smartphones.
The popularity and demand for touchscreen devices grew exponentially in the 2000s. As technology improved, touchscreens became more responsive and accurate, allowing for more precise interactions. This led to the widespread adoption of the technology, with touchscreens now being used in virtually all smartphones and tablets.
Today, touchscreens are an integral part of our lives. They allow us to interact with our devices in ways that would have been unimaginable just a few decades ago. From ordering food to playing games, the possibilities are endless.
Exploring the People Behind the Development of Smartphone Touchscreens
The development of the smartphone touchscreen was a collaborative effort involving many different people and technologies. Eric A. Johnson and John F. Elias are two of the most important figures in the history of the touchscreen. Johnson developed the first capacitive touchscreen in 1965, while Elias developed the first resistive touchscreen in 1982. Both inventions laid the groundwork for the development of the modern touchscreen.
The development of the touchscreen also involved the filing of several patents and licensing agreements. Andrew H. Van Dam was granted a patent for his graphical user interface in 1983, and Apple licensed the touchscreen technology from Elographics for use in its Newton PDA in 1988.

In addition to Johnson and Elias, there were many other innovators involved in the development of the touchscreen. These include researchers from universities and companies around the world, as well as scientists and engineers from various fields. Their contributions helped make the touchscreen what it is today.
Conclusion
The invention of the smartphone touchscreen changed the way we interact with technology and revolutionized the way we live our lives. While the concept of the touchscreen dates back to the mid-1960s, it took decades of research and development to bring it to the level of sophistication we enjoy today. The development of the touchscreen was a collaborative effort involving many different people and technologies, from Eric A. Johnson to John F. Elias. Their contributions helped make the touchscreen what it is today.
