Abstract
A touch panel device with reconfigurable sensing points includes a panel, a plurality of sensing points, a plurality of selectors, and a controller. The sensing points, are arranged on the panel for sensing a touch generated from an external object and generating a corresponding signal. Each selector has a first terminal connected to a corresponding sensing point, a second terminal connected to a common output terminal, and a control terminal. The controller is connected to the control terminal of each selector for controlling the plurality of selectors to be electrically connected to the common output terminal or not. The controller configures the control terminals of the plurality of selectors to allow some of the sensing points to be electrically connected to the common output terminal, so as to proceed with a hierarchical block touch sensing.
