Backlight Module

摘要

A backlight module includes a back frame, a light guide plate and a cushion disposed inside the back frame. The back frame includes a base and side walls perpendicular to the base. The cushion is arranged on an area between one of the side walls of the back frame and the LGP, used for fixing the LGP inside the back frame. Air chamber is disposed inside the flexible cushion. At least one exhaust vent is disposed on a non-contact outer wall of the cushion. The air chamber communicates with the outside air via the exhaust vent, and the cushion is fixed on one of the side walls of the back frame. The backlight module is capable of stabilizing an LGP on its position when bearing instantaneous impact forces. Besides, there is enough room for the LGP to swell without being intervened by the backlight module.

1. A backlight module, comprising:
a back frame, comprising a base and a plurality of side walls perpendicular to the base; a light guide plate (LGP), disposed inside the back frame; a cushion, arranged on an area between one of the plurality of side walls of the back frame and the LGP, used for fixing the LGP inside the back frame, and being flexible; an air chamber disposed inside the flexible cushion, at least one exhaust vent disposed on a non-contact outer wall of the cushion, the air chamber communicating with the outside air via the exhaust vent, and the cushion fixed on one of the plurality of side walls of the back frame; wherein the internal diameter of the exhaust vent is far smaller than the internal diameter of the air chamber, and when the cushion bears instantaneous impact forces, the quantity of the air in the air chamber exhausting via the exhaust vent is far smaller than the quantity of the air in the air chamber.
