Embodiment Construction

[0011] refer to figure 1 and figure 2 , a preferred embodiment of the backlight module 2 of the present invention includes a frame unit 3, a light source 4 arranged on the frame unit 3, and a light source 4 arranged on the frame unit 3 and used to receive the light emitted by the light source 4 Light guide plate 5 for light. The frame unit 3 includes an outer frame 30, a side plate 31 arranged transversely on the outer frame 30, a back plate 32 arranged on one side of the side plate 31 and arranged vertically, and a back plate 32 arranged on the back The heat conducting plate 33 on the plate 32. Wherein, the light source 4 is arranged on the side plate 31, and includes a plurality of light-emitting diodes 41 arranged at intervals (due to the relationship of viewing angle figure 1 only one is displayed). The light guide plate 5 is arranged on the outer frame 30 and corresponds to the light source 4, but it should be noted that the overall structure of the outer frame 30 an...

Abstract

The invention relates to a backlight module. The backlight module comprises a frame unit, a light source arranged on the frame unit and a light guide plate which is arranged on the frame unit and used for receiving light rays emitted by the light source. The frame unit comprises a side plate transversely arranged, a back plate longitudinally arranged on one side of the side plate and a heat-conducting plate arranged on the back plate. The height of the back plate is defined as H. The back plate is provided with a bottom edge, a predetermined area and a penetrating groove, wherein the predetermined area is in the position 1 / 4 H to 1 / 3 H away from the bottom edge, and the penetrating groove is located in the predetermined area and extends transversely. The heat-conducting plate is not higher than the penetrating groove. The heat insulation design is formed through the penetrating groove, heat which is produced by the light source and conducted to the position relatively above the back plate is substantially reduced, and the phenomenon that the back plate is bent due to the heat is effectively prevented.

Description

technical field [0001] The invention relates to a light source module, in particular to a backlight module. Background technique [0002] Backlight modules have been widely used in the manufacture of various flat panel displays, and the thinning of flat panel displays has gradually become a trend. A backlight module usually includes a light source, a backplane, and a light guide plate. As the overall structure becomes thinner, the backplane is easily affected by the heat generated by the light source, resulting in bending. [0003] The most common method at present is to provide a heat conduction sheet to conduct heat generated by the light source to accelerate heat dissipation. However, the above design still cannot effectively improve the bending phenomenon of the backplane caused by heat. Contents of the invention [0004] Therefore, the object of the present invention is to provide a backlight module that effectively prevents the backplane from being bent due to heat...
