Abstract

The present invention relates to a backlight module, comprising a back plate, a light guide plate, at least one light source, an optical film, and a glue frame; wherein, the light guide plate is arranged on the back plate, and has at least one light-in surface and one light-out surface; the at least one light source faces to the at least one light-in surface; the optical film is arranged at the light-out surface of the light guide plate; the glue frame is arranged at a periphery of the light guide plate, and has a rib part and a plurality of column parts, the rib part is arranged at a relative position over a periphery of the light-out surface, the column parts are connected with the rib part and arranged between the rib part and the back plate, so that an end face of the column part is lower than the light-out surface. Therefore, the backlight module can reduce processing time and part cost, prevent the problem of fracture and melt of the light guide plate after being heated, and fix the optical film and the light guide plate.

Description

technical field [0001] The invention relates to a backlight module, in particular to a backlight module which has a plastic frame and the end faces of a plurality of pillars of the plastic frame are lower than the light-emitting surface. Background technique [0002] Figure 1A A top view showing the existing backlight module disclosed in Taiwan Patent No. I287664; Figure 1B A cross-sectional view showing a conventional backlight module disclosed in Taiwan Patent No. I287664; Figure 1C A top view of an optical film of a conventional backlight module disclosed in Taiwan Patent No. I287664 is shown. with reference Figure 1A to Figure 1C , the existing backlight module 1 includes a backplane 11 , a light guide plate 12 , a light source 13 , a plastic frame 14 and a multilayer optical film 15 . The light guide plate 12 is disposed on the back plate 11 and has a light emitting surface 121 . The light source 13 is close to a side wall of the light guide plate 12 . [0003]...
