Abstract
A sensing electronic device includes a substrate, and a reference voltage control unit. The sensing array is arranged on the substrate, and includes a first sensing electrode and a second sensing electrode. The reference voltage control unit is electrically connected to the sensing array. In an operation period, the reference voltage control unit has a first voltage, the first sensing electrode has a second voltage, and the second sensing electrode has a third voltage, wherein a difference between the first voltage and the second voltage is different from a difference between the first voltage and the third voltage.
