INPUT DEVICE
Document Type and Number:
WIPO Patent Application WO/2024/004279
Kind Code:
A1
Abstract:
Provided is an input device comprising an input detecting unit, the input detecting unit comprising: a circuit board; an electrostatic electrode which is for electrostatic capacitance detection and is provided on the circuit board; a light source provided on the circuit board; a light-guiding plate provided below an operating surface and above the electrostatic electrode, and having a first side surface facing the light source and a second side surface not facing the light source; and a light-shielding member that forms a frame that surrounds the light-guiding plate, and has a light-shielding wall that is in contact with the second side surface of the light-guiding plate. The first side surface and the second side surface of the light-guiding plate, which are adjacent to each other, form an obtuse angle, the first side surface is perpendicular to the upper surface and the lower surface, the second side surface is slanted downward, and the light-shielding wall of the light-shielding member is slanted upward.
