Effectively, this was used for temporarily drawing arrows or circles onto a live television broadcast, as described in US 2487641A, Denk, William E, 'Electronic pointer for television images', issued. One predecessor of the modern touchscreen includes stylus based systems.ġ946 DIRECT LIGHT PEN - A patent was filed by Philco Company for a stylus designed for sports telecasting which, when placed against an intermediate cathode ray tube display (CRT) would amplify and add to the original signal. This was a further development of the self-capacitance screen (right), also developed by Stumpe at CERN in 1972. The prototype x-y mutual capacitance touchscreen (left) developed at CERN in 1977 by Frank Beck, a British electronics engineer, for the control room of CERN's accelerator SPS ( Super Proton Synchrotron).

Display manufacturers and chip manufacturers have acknowledged the trend toward acceptance of touchscreens as a user interface component and have begun to integrate touchscreens into the fundamental design of their products. Historically, the touchscreen sensor and its accompanying controller-based firmware have been made available by a wide array of after-market system integrators, and not by display, chip, or motherboard manufacturers. Touchscreens are found in the medical field, heavy industry, automated teller machines (ATMs), and kiosks such as museum displays or room automation, where keyboard and mouse systems do not allow a suitably intuitive, rapid, or accurate interaction by the user with the display's content. The popularity of smartphones, tablets, and many types of information appliances has driven the demand and acceptance of common touchscreens for portable and functional electronics. Touchscreens are important in educational settings such as classrooms or on college campuses. They play a prominent role in the design of digital appliances such as personal digital assistants (PDAs) and some e-readers. They can also be attached to computers or, as terminals, to networks. They are common in point-of-sale (POS) systems, automated teller machines (ATMs), and electronic voting machines. Touchscreens are common in devices such as smartphones, handheld game consoles, and personal computers. The user can use the touchscreen to react to what is displayed and, if the software allows, to control how it is displayed for example, zooming to increase the text size.Ī touchscreen enables the user to interact directly with what is displayed, instead of using a mouse, touchpad, or other such devices (other than a stylus, which is optional for most modern touchscreens). Some touchscreens use ordinary or specially coated gloves to work, while others may only work using a special stylus or pen.

The display is often an LCD, AMOLED or OLED display.Ī user can give input or control the information processing system through simple or multi-touch gestures by touching the screen with a special stylus or one or more fingers. Touchscreens are commonly found in smartphones, tablets, laptops, and other electronic devices. The touch panel is typically layered on the top of the electronic visual display of a device. It consists of both an input device (a touch panel) and an output device (a visual display). Input and output device A user operating a touchscreen Smart thermostat with touchscreenĪ touchscreen (or touch screen) is a type of display that can detect touch input from a user.
