    摘要: A diffusion plate (20) includes at least two diffusion units (21), each diffusion unit including at least one connecting portion (23). The connecting portions (23a, 23b) of each two adjacent diffusion units mate with each other, thereby connecting all the diffusion units together. The number of diffusion units may be increased or decreased according to the size of a liquid crystal display to be produced. This eliminates the need to alter the production means for differently sized backlight modules, thereby reducing costs and increasing production efficiency. In another embodiment, a diffusion plate (50) includes at least two diffusion units (51). Each diffusion unit includes at least one connection protrusion (53a). At least one interconnecting member (53) is disposed between each two adjacent diffusion units. The interconnecting member and the connecting protrusions mate with each other, thereby connecting all the diffusion units together. A related backlight module (500) is also provided.

    摘要: An exemplary light guide plate (20) includes a transparent body (21) having a major surface (24) and a light diffusing structure (28) coated or embossed on the major surface of the transparent body. The light diffusing layer makes light beams emitting out from the light guide plate more uniform. Therefore the backlight module does not need a thick light diffusing plate. This means the backlight module is thin, assembly of the backlight module is simplified, and costs are reduced.

    摘要: An exemplary backlight module (2) includes a light guide plate (23), a light source (25), a light source driver (27), and a frame (21). The light source is provided adjacent to the light guide plate. The light source driver is directly connected with the light source. The frame includes an upper frame (211) and a lower frame (212). The upper frame and the lower frame cooperatively form a space to accommodate the light guide plate, the light source, and the light source driver.

    摘要: A backlight module (5) includes a light guide plate (51) and a light source (52). The light guide plate includes a first light incident surface (510), a second light incident surface (512) adjacent the first light incident surface. The first light incident surface and the second light incident surface cooperatively define a first groove (54) therebetween. The light source is disposed in the first groove. With this configuration, there is no need for additional space for the light source beyond an end of the light guide plate. Thus an overall length of the backlight module is shortened. Furthermore, a top end (533) of the reflector can be disposed in a second groove (59) defined between two adjacent side surfaces at the end of the light guide plate. Thus an overall height of the backlight module is shortened. The reduced overall length and height of the backlight module makes it compact.

    摘要: A backlight driving circuit includes a light driving unit, which includes a constant current unit, and a light source operated by the constant current unit. The light driving unit further includes a feedback control unit and a detection circuit. The detection circuit detects the light source and outputs at least a voltage feedback signal to the feedback control unit. The feedback control unit obtains a prestored power parameter corresponding to the voltage feedback signal and outputs an adjusting signal to the constant current unit to adjust the constant current of the light source.

    摘要: An exemplary light guide plate (2) includes a light output surface (21) on one side of the light guide plate; a bottom surface (22) on an opposite side of the light guide plate; and a plurality of V-shaped refraction interfaces (24) disposed between the light output surface and the bottom surface. The V-shaped refraction interfaces are formed in the light guide plate, which prevents the V-shaped refraction interfaces being pressed by other optical elements. That is, the V-shaped refraction interfaces are secure during assembly and transportation of a backlight module employing the light guide plate. Moreover, the V-shaped refraction interfaces do not occupy a large amount of space, which means that the backlight module can be made thinner.
