Abstract: An optical image recognition device and a method for fabricating the same are disclosed. The device includes a flexible printed circuit board, an image sensor, a glue, an optical collimator, a supporting ring, a sealant, and an optical filter. The top of the flexible printed circuit board is provided with a recess, the image sensor is located in the recess, the sidewalls of the image sensor and the recess are separated from each other, and the image sensor is coupled to the flexible printed circuit board through conductive wires. The glue adheres to the flexible printed circuit board and the image sensor and covers the conductive wires. The optical collimator is disposed on the image sensor. The supporting ring, disposed on the flexible printed circuit board, surrounds the glue and the optical collimator. The optical filter, disposed on the sealant, shields the optical collimator and the image sensor.

Abstract: An exemplary liquid crystal display (20) includes a liquid crystal panel (22), a flexible printed circuit (23) connected to the liquid crystal panel, and a backlight module (25) configured for illuminating the liquid crystal panel. The flexible printed circuit includes a first grounding member (231). The backlight module includes a metal frame (28). The metal frame includes a first holding member (281). The first holding member of the metal frame holds the first grounding member of the flexible printed circuit such that the first grounding member is electrically connected with the metal frame.

Abstract: A backlight module (100) includes a light guide plate (56), a bottom tray (50) having a spring finger (506), a radiation element (59) disposed adjacent to the light guide plate, and a frame (55) receiving the light guide plate and the radiation element. The light guide plate includes a light incident surface (560), and a side surface (564) opposite to the light incident surface. An ear (566) is formed on the side surface, and the spring finger presses the light guide plate toward the radiation element. A distance between the radiation element and the light incident surface is thereby decreased or even eliminated. This enables the backlight module to provide improved brightness and uniformity of emitting luminance.

Abstract: A backlight module (5) includes a light guide plate (56) having an incident surface (563), a frame (55) for accommodating the light guide plate, and a light source (59) accommodated in the frame and disposed adjacent to the incident surface. The frame includes at least one elastic element (5556) urging the light guide plate, thus keeping the incident surface in contact with the light source.

Abstract: An exemplary backlight module (12) includes a light guide plate (14), and a frame assembly (16). The frame assembly includes a first frame (18) and a second frame (19) integrally formed with the first frame. The first frame accommodates the light guide plate, and has a flared protrusion (184). The second frame defines a flared hole (197) therein. The protrusion of the first frame is locked in the hole.
