Title:
TOUCH PANEL DEVICE AND CALIBRATION METHOD FOR TOUCH PANEL DEVICE
Document Type and Number:
WIPO Patent Application WO/2019/135280
Kind Code:
A1
Abstract:
A touch detection unit (11) detects the capacitance at each coordinate in a capacitative touch panel (2) and outputs same as capacitance detection values. A region specification unit (12) specifies a region at which an operation device (7) is present on the capacitative touch panel (2), on the basis of the capacitance detection values at each coordinate as detected by the touch detection unit (11). A calibration control unit (13) commands the calibration of regions at which the operation device (7) is not present on the capacitative touch panel (2), on the basis of the specification results from the region specification unit (12). A calibration processing unit (14) calibrates the detection sensitivity of the capacitance in regions where the operation device (7) is not present on the capacitative touch panel (2), in accordance with the instructions from the calibration control unit (13).
