Abstract
(EN)
Provided is an optical sensor and an electronic device for suppressing a decline in light-dispersion characteristics. The optical sensor includes a light-receiving element, an optical filter (140) through which light of a specified wavelength among incident light passes onto the light-receiving region of the light-receiving element, and an angle-limiting filter (120) for limiting the incidence angle of incident light passing through the optical filter (140). Taking θA to be the limit angle of the angle-limiting filter (120) and the RTP as the height from the top surface of the angle-limiting filter (120) to the top surface of the optical filter, then if the distance from the edge of the optical filter (140) in plan view in relation to the top surface of the angle-limiting filter (120) to the edge of an opening of the angle-limiting filter (120) is defined as an overlap distance (OV), then tan-1(OV/RTP)>θA is fulfilled.

La présente invention porte sur un capteur optique et un dispositif électronique pour supprimer un déclin de caractéristiques de dispersion de lumière. Le capteur optique comprend un élément de réception de lumière, un filtre optique (140) à travers lequel une lumière d'une longueur d'onde spécifiée parmi une lumière incidente passe sur la région de réception de lumière de l'élément de réception de lumière, et un filtre de limitation d'angle (120) pour limiter l'angle d'incidence d'une lumière incidente passant à travers le filtre optique (140). En prenant θA comme étant l'angle limite du filtre de limitation d'angle (120) et le RTP en tant que la hauteur depuis la surface supérieure du filtre de limitation d'angle (120) vers la surface supérieure du filtre optique, puis si la distance depuis le bord du filtre optique (140) dans une vue en plan par rapport à la surface supérieure du filtre de limitation d'angle (120) vers le bord d'une ouverture du filtre de limitation d'angle (120) est définie en tant que distance de recouvrement (OV), alors tan-1(OV/RTP)>θA est rempli.
