Touchscreen
input/output device usually layered on the top of an electronic visual display
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.
This brief starts where responsible research should: with the source description of “Touchscreen” as input/output device usually layered on the top of an electronic visual display. Everything that follows is an evidence route, not borrowed authority.
Why this record matters
The subject matters to the general reference register because the source frames it as input/output device usually layered on the top of an electronic visual display. Its deeper value depends on whether names, dates, institutions and citations support that framing.
Named sources, stable identifiers and responsible institutions provide the strongest route from overview to verifiable evidence. The source revision retrieved here is dated Sep 5, 2026. The linked authority identifier is Q165970. The Library of Congress control number is sh2007001536. 1 of 1 selected statements include explicit references; 1 carry qualifiers and 0 use preferred rank.
Overview language is designed for orientation and should not be treated as a substitute for the evidence cited beneath it. The source lead contains qualifying language; that uncertainty should survive quotation, summary and reuse. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
