1. A driver apparatus, configured to drive an electronic paper display panel to perform a touch sensing operation, the driver apparatus comprising:

  • a scanner apparatus, configured to scan a plurality of sensing blocks on the electronic paper display panel to perform the touch sensing operation, wherein each of the sensing blocks comprises one or a plurality of sensing devices, and the sensing blocks are arranged in an array; and

    a sensing apparatus, electrically connected to the scanner apparatus, and configured to control the scanner apparatus to scan the sensing blocks, wherein the sensing apparatus charges/discharges each of the sensing blocks according to a first voltage and a second voltage, so as to generate a relaxation signal, a pulse difference of the relaxation signal is changed by a touch object, and the touch object is a conductor,wherein a touch position of the touch object on the electronic paper display panel is determined according to a relaxation frequency of the relaxation signal of each of the sensing blocks.
