Title:
DETECTOR
Document Type and Number:
Japanese Patent JP2020087375
Kind Code:
A
Abstract:
To provide a detector that is capable of higher speed detection.SOLUTION: A detector comprises: a plurality of detection electrodes Rx; a detection circuit that is connected to the detection electrodes Rx and detects a detection signal according to a change in capacity of the detection electrodes Rx; and a connection circuit that connects or disconnects the detection electrodes Rx and the detection circuit. The detection electrodes Rx connected to the detection circuit are determined based on a Walsh type Hadamard matrix, and the detector can execute a first mode in which detection with a connection pattern of the detection electrodes Rx and the detection circuit corresponding to part of the rows included in the Walsh type Hadamard matrix is performed over a first elapsed time.SELECTED DRAWING: Figure 9
