Abstract: An exemplary backlight module (20) includes a light guiding plate (240) with a light incident surface (241), a frame (230) receiving the light guiding plate, and at least one point light source (260) disposed between the light incident surface of the light guiding plate and the frame, the at least one point light sources includes a light emitting portion (262) and an elastic member (263). The light emitting portion and the elastic member are at opposite sides of the at least one point light source, and the elastic member elastically urges the frame such that the light emitting portion firmly contacts the light incident surface. A liquid crystal display using the backlight module is also provided.

Abstract: A liquid crystal display includes a liquid crystal panel and a backlight module parallel to the liquid crystal panel. The backlight module includes a light guide plate, a light source and a flexible printed circuit. The light guide plate includes a light incident surface. The light source is provided adjacent to the light incident surface of the light guide plate. The flexible printed circuit includes a light source driving end. The light source driving end is electrically connected with the light source. The light source driving end is bent and is sandwiched between the liquid crystal panel and the light guide plate. The light source driving end abuts the light guide plate.

Abstract: An exemplary backlight module (3) includes a light guide plate (32) and a frame (34) accommodating the light guide plate. The light guide plate includes a main body including two side surfaces (321), and two sliding strips (325). The sliding strips extend outward from the side surfaces of the main body. Each sliding strip includes a flexible detent (326). The frame includes two opposite first walls (341). The first walls defines two sliding guides (3411) slidably receiving the light guide plate whereby the light guide plate is slidable into the frame and detachably fixed in the frame by snapping engagement of the flexible detents with the frame.

Abstract: An exemplary backlight module (20) includes an optical film assembly (22) having at least two optical films, each optical film having at least one ear (221) attached together; a frame (24) having at least one concave groove (243) receiving the at least one ear.

Abstract: An exemplary liquid crystal display (1) includes a liquid crystal panel (13) and a frame (12) receiving the liquid crystal panel. The frame includes a stopper (126) configured for blocking the liquid crystal panel from being pulled up. The liquid crystal display further includes a light guide plate (17) having a light incident surface (172). Light beams emitted from a plurality of point illuminators (18) enter the light incident surface (172) of the light guide plate 17, and the desired optical performance of liquid crystal display is stably maintained.

Abstract: An exemplary backlight module (2) includes a frame (22) having a plurality of side walls (221), a light guide plate (23) having a light incident surface (231) and a light output surface (233) contained in the frame, at least one optical films (21) disposed adjacent to the light output surface of the light guide plate, and a light source assembly (25) disposed adjacent to the light incident surface of the light guide plate. The frame has at least one elastic fixing clip (225) for fixing the at least one optical films therein. With this configuration, the elastic fixing clip can firmly fix the optical films in the plastic frame. Therefore, the backlight module having the optical films and the plastic frame can be mechanically stable and operate properly.
