INPUT DEVICE
Document Type and Number:
WIPO Patent Application WO/2024/024150
Kind Code:
A1
Abstract:
Provided is an input device in which the influence of a light-emitting state of a light-emitting diode on the detection capacity of an electrostatic sensor is suppressed. This input device includes: a light-emitting diode; a switching element which is connected in series to the light-emitting diode and switches on/off the light-emitting diode; an electrostatic sensor which has a detection electrode capacitively coupled with a circuit portion between the light-emitting diode and the switching element; and a capacitor having a first terminal connected to the circuit portion and a second terminal connected to a fixed potential point.
