Touchscreens are display screens that detect the presence and location of a touch within the display area. They allow users to interact directly with what is displayed, making it easier to navigate and control devices. Touchscreens are commonly found in devices like smartphones, tablets, and computers. There are two main types of touchscreens: resistive and capacitive. Resistive touchscreens respond to pressure, while capacitive touchscreens use the electrical properties of the human body. Both types have their advantages and are used in various applications, from kiosks to smart appliances.
