May 18, 2021 By WatElectronics

This article lists 100 Touch Screen Technology MCQs for engineering students. All the Touch Screen Technology Questions & Answers given below includes solution and link wherever possible to the relevant topic.

Touch screen technology is common across the globe, the first touch screen system was created in 1965 by E.A. Johnson. Scientists at the University of TORONTO invented the first multi-touch display in the 1980s.

The touch screen has made various devices so simpler to use, and the required task will be done by a simple tab with little swap and will find a touch screen everywhere on smartphones, laptops, computer screens, etc.

The basic touch screen has three components they are sensors, controllers, and software. There are six types of touch screen systems like resistive, capacitive, infrared, SAW, optical imaging, and acoustic pulse recognition touch screen.
