Abstract
The present disclosure discloses a terminal, a touch control unit, a touchscreen, a screen protector, and an operation detection apparatus and method, and pertains to the field of terminal control. The terminal includes a touchscreen, a controller connected to the touchscreen, and at least one touch control unit, where the touch control unit includes a detection electrode, an induction electrode, and a conducting wire connecting the detection electrode and the induction electrode. The detection electrode is located outside a touch area of the touchscreen, the induction electrode is located in the touch area of the touchscreen, and the induction electrode is coupled to at least one capacitance node on the touchscreen. An existing capacitance node on the touchscreen identifies a touch operation performed by a user on the detection electrode disposed outside the touchscreen, and the terminal is controlled according to the touch operation.
