Abstract: An exemplary backlight module (20) includes a light guide plate (250) including a light incident surface (251), a frame (280) accommodating the light guide plate and including a side wall (281), light emitting units (270) adjacent to the light incident surface of the light guide plate, and elastic members (240). The elastic members are detachably engaged with the side wall of the frame. Each elastic member is configured to elastically urge a corresponding light emitting unit such that the light emitting unit abuts the light incident surface of the light guide plate. In other examples, each elastic member elastically urges the side wall of the frame, or elastically urges the light guide plate. A liquid crystal display device using the backlight module is also provided.

The first ear is received in the notch, and a top surface of the first ear is coplanar with a top surface of the supporting board at the notch.

Abstract: An exemplary backlight module includes a light guide plate (14), a frame (15), and an illuminator (16). The light guide plate includes a light incident surface (142), and a side surface (149) opposite to the light incident surface. The illuminator is adjacent the light incident surface. The frame receives the light guide plate and the illuminator, and includes an elastic member (156) either elastically pushing the side surface toward the illuminator or elastically pushing the illuminator toward the light incident surface.

Abstract: A backlight module (2) includes a light source (21) and a light guide plate (23). The light source includes a lamp (231) and two electrode cases (233), the two electrode cases engage with opposite ends of the lamp. The light guide plate includes a light output surface (212), a bottom surface (213), two adjacent light incident surfaces (211), two side surfaces (214), and two holding devices (215). The two holding devices are respectively provided at diagonally opposite corners of the light guide plate, where the light incident surfaces are respectively adjacent the side surfaces, and the holding devices are for retaining electrode cases. The light source is disposed adjacent to the light incident surfaces. The lamp are not liable to shock, so the lamp can not be damaged. Further, the backlight module eliminates the need for rubber rings. Thereby reducing the cost of the backlight module.

Abstract: An exemplary backlight module includes a light guide plate (330) and a frame (340). The light guide plate includes a light emitting surface (331) and a bottom surface (332) at opposite of the light guide plate. The frame is configured for accommodating the light guide plate. The frame includes a bottom plate (341). The bottom plate includes a reflective surface (343) abutting the bottom surface of the light guide plate.

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.
