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.

Description

Technical field [0001] The present invention relates to the technical field of touch panels, in particular to a touch panel device capable of reorganizing sensing points and a sensing method. Background technique [0002] The technical principle of the touch panel is that when a finger or other medium touches the screen, it detects voltage, current, sound waves or infrared rays according to different sensing methods, and then measures the coordinate position of the touch point. For example, the resistive touch panel uses the potential difference between the upper and lower electrodes to calculate the position of the pressure point to detect the touch point. The capacitive touch panel uses the capacitance change generated by the electrostatic combination between the arranged transparent electrodes and the human body to detect its coordinates from the generated current or voltage. [0003] According to the principle of capacitive touch technology, it can be divided into two technolo...
