Touch Screen Controllers are devices that can convert a user's physical touch operations (such as tapping, swiping, zooming, etc.) into digital signals that can be recognized by a computer or other electronic device. Designed to detect and parse user input on touch screens. It is responsible for receiving signals from the touchscreen panel, processing these signals to identify the position, force and duration of the touch, and then converting this information into digital signals that are sent to the main processor for subsequent instruction processing.
