Define touch screen

Types of touch screens

A touch screen is a device that allows a user to operate a machine by touching the screen with a finger or stylus. It consists of a sensor placed over a visual display that reacts when a user touches a part of the display. This screen seamlessly combines both the input and output functions of a computer, eliminating traditional keyboard and mouse requirements, hence, making interaction quicker and with less effort. It also provides direct access to virtual buttons, icons, and other graphical elements on the display.

In a define touch screen, there are two main components: the actual touch sensor, which is the part that detects the user's touch, and the visual display, on which everything viewed shines through. This defines a touchscreen technology that allows users to interact with electronic devices by touching the screen. To define screens, there are various kinds of touch screens according to their technologies, including resistive, capacitive, and infrared.

• Resistive touch screen: This touch screen has two layers of conductive material separated by dots or particles. The layers only touch each other when a finger or stylus touches the screen. When touched, the coordinates of that point are recorded, allowing the system to detect the user's input.
• Capacitive touch screen: Unlike resistative touch screens, these screens have a series of capacitors arranged in a grid pattern on the glass surface. When a person touches the screen, it detects the change in capacitance at that point. This change is then used to determine the user's input. Capacitive touch screens are known for their brightness and clarity as they use the electrical properties of the human body to function.
• Infrared touch screen: Infrared touch screens do not have any layers of sensors or protective glass. Instead, they use an invisible grid of infrared light beams that are broken when a finger or stylus touches the screen, thus determining the location of the touch.
