Abstract
A finger feature module includes a light guide seat including a frame and a plate body disposed in the frame and having an eccentrically disposed through hole, a circuit board assembly having a first portion disposed in the frame and located above the plate body and a second portion passing through the through hole to be at least partially located below the plate body, a feature sensor on the first portion of the circuit board assembly, and a plurality of illuminants electrically connected to the circuit board assembly, wherein two of the illuminants are located at two opposite ends of the through hole, and a virtual connecting line of the two illuminants overlaps the through hole.
Claims19
A finger feature module, comprising:
- a light guide seat comprising a frame and a plate body, the plate body disposed in the frame and having a through hole eccentrically disposed, wherein the plate body is connected to a middle section of the frame to define an upper room and a lower room in the frame;
- the upper room and the lower room are respectively above and below the plate body;
- the through hole communicates the upper room with the lower room;
- a circuit board assembly having a first portion and a second portion, the first portion of the circuit board assembly disposed in the frame and located above the plate body, the second portion of the circuit board assembly passing through the through hole to be at least partially located below the plate body;
- a feature sensor disposed on the first portion of the circuit board assembly;
- and
- a plurality of illuminants electrically connected to the circuit board assembly, wherein two of the plurality of illuminants are located at two opposite ends of the through hole, and a virtual connection line of the two of the plurality of illuminants overlaps the through hole.
A finger feature module, comprising:
- a light guide seat comprising a frame and a removable board, the removable board removably disposed in the frame to define a through hole;
- a circuit board assembly having a first portion and a second portion, the first portion of the circuit board assembly disposed in the frame and located above the removable board, the second portion of the circuit board assembly passing through the through hole to be at least partially located below the removable board;
- a feature sensor disposed on the first portion of the circuit board assembly;
- and
- one or more illuminants electrically connected to the circuit board assembly to emit light toward the light guide seat.
A finger feature module, comprising:
- a light guide seat comprising a frame and a plate body, the frame defining an accommodation space, the plate body disposed in the frame to divide the accommodation space into an upper room and a lower room, the plate body having a through hole communicating the upper room with the lower room;
- a circuit board assembly comprising a flexible printed circuit board, a first circuit board, and a second circuit board, the first circuit board and the second circuit board disposed on the flexible printed circuit board, the flexible printed circuit board extending through the through hole from the upper room to the lower room, the first circuit board located in the upper room, the second circuit board located in the lower room;
- a feature sensor disposed on the first circuit board;
- and
- an illuminant electrically connected to the circuit board assembly to emit light toward the light guide seat.
