Abstract
A noise reduction device for use in a backlight module includes a plurality of noise reduction devices, each comprising a main body and an extension portion. The extension portion is adapted to cushion the interface between a lamp holder and a back bezel of the backlight module, so as to reduce pop noises generated by contact during temperature changes.

In a backlight module for a display device that includes a lamp holder and a back bezel having a top surface that is generally parallel to a display surface of the display device, a noise reduction device for disposition between the lamp holder and the back bezel, the noise reduction device comprising a plurality of noise reduction members each comprising:
- a main body, having at least one recess for holding at least one lamp, and having a bottom side situated at the top surface of the back bezel;
- and
- an extension portion, extending outward from the bottom side of the main body along the top surface of the back bezel, such that the extension portion is adapted to substantially isolate the lamp holder from the back bezel notwithstanding any occurrence of thermal expansion over changes in operational temperature of the backlight module.
A noise reduction device for use in a backlight module for use in a display device, the noise reduction device disposed between a lamp holder and a back bezel of the backlight module, the back bezel having a top surface that is generally parallel to a display surface of the display device, the noise reduction device comprising:
- a plurality of sequentially arranged main bodies, each having at least one recess, for holding at least one lamp;
- and
- a plurality of extension portions disposed between the plurality of main bodies and the top surface of the back bezel, and serially connected to the plurality of main bodies.
