Title:
TOUCH PANEL DEVICE AND TOUCH PANEL DEVICE CONTROL METHOD
Document Type and Number:
WIPO Patent Application WO/2021/205712
Kind Code:
A1
Abstract:
Provided is a touch panel device capable of reducing a processing load of a noise filter. A touch panel device (100) includes: a mutual capacitance touch panel; an extraction unit (6) that extracts, from a plurality of first electrodes (2), at least one specific first electrode corresponding to touch coordinates; and a coordinates identification unit (7) that identifies the touch coordinates by extracting, from a plurality of second electrodes (3), at least one specific second electrode corresponding to the touch coordinates, and applying a first noise filter to a measurement value corresponding to the intersection between the extracted first electrode and the extracted second electrode.
