Abstract
There is provided a parallel sensing touch control device including a capacitive sensor array processed by differential unit. In one detection interval, the device is concurrently conducting more than one sensing electrode of the capacitive sensor array so as to reduce a scanning interval of the capacitive sensor array. The differential unit performs a differential operation on detected signals to cancel out common mode noise.
