Driver apparatus
First Claim
1. A driver apparatus, driving an electronic paper display panel to perform a touch sensing operation, the driver apparatus comprising:
- a scanner apparatus, scanning 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 controlling 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.

Abstract
A driver apparatus configured to drive an electronic paper display panel to perform a touch sensing operation is provided. The driver apparatus includes a scanner apparatus and a sensing apparatus. The scanner apparatus scans multiple sensing blocks of the electronic paper display panel to perform the touch sensing operation. Each sensing block includes one or more sensing devices. The sensing blocks are arranged in an array. The sensing apparatus is electrically connected to the scanner apparatus. The sensing apparatus controls the scanner apparatus to scan the sensing blocks. The sensing apparatus charges/discharges each sensing block according to a first voltage and a second voltage, so that a relaxation signal is generated. A pulse difference of the relaxation signal is changed by the touch object. The touch object is a conductor. 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 sensing block.
