A Touch Panel is an interactive display interface that allows users to control and interact with electronic devices through touch input. Widely used in smartphones, tablets, kiosks, and industrial control systems, touch panels enable intuitive and efficient user experiences. They respond to finger or stylus gestures, such as tapping, swiping, and pinching, to perform various functions. Touch panels can be made using resistive, capacitive, or infrared technologies, each offering different levels of sensitivity and durability. These interfaces support multitouch capabilities, provide clear visual feedback, and can be integrated into various applications to enhance usability and functionality.
