Touchscreen

Article summary

with touchscreen A touchscreen (or touch screen) is a type of display that can detect touch input from a user to do a specific task. It consists of both an input device (a touch panel) and an output device (a visual display). The touch panel is typically layered on the top of the electronic visual display of a device. Touchscreens are commonly found in smartphones, tablets, laptops, and other electronic devices. The display is often an LCD, AMOLED or OLED display. A person 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. Some touchscreens use ordinary or specially coated gloves to work, while others may only work using a special stylus or pen. 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. A touchscreen allows users to interact directly with on-screen content, rather than using indirect input devices such as a mouse or touchpad. Touchscreens are commonly found on smartphones, tablets, kiosks, and many modern laptops, where they allow tapping, swiping, and pinching to perform actions on the screen. Touchscreens are common in devices such as smartphones, handheld game consoles, and personal computers.…
