<p>A multipoint touch device and a method for carrying out multipoint touch detection on the same, belonging to the field of touch of touch screens. The multipoint touch device comprises a touch screen, a signal detection unit, a processor and a storage, wherein the processor controls the signal detection unit to carry out self-capacitance detection on the touch screen and stores the detected touch points into the storage; the processor controls the signal detection unit to carry out mutual capacitance detection on the detected touch points to obtain real touch points therefrom. The solution can effectively remove ghost points and remarkably lower the scanning times on a coil induction line, thereby remarkably shortening the detection time, increasing the detection speed and the touch reaction speed, and being widely applied to the field of the touch of the touch screens.</p> |
