Backlight module having elastic structures at frame and liquid crystal display using same
An exemplary backlight module ( 42 ) includes a light guide plate ( 47 ) and a frame ( 46 ) for receiving the light guide plate. The frame includes a plurality of side walls ( 462 ) and a plurality of elastic structures ( 463 ). The elastic structures extend from top surfaces of the side walls.
1 . A backlight module, comprising:
a light guide plate; and
a frame for receiving the light guide plate, the frame comprising:
a plurality of side walls; and
a plurality of elastic structures extending from top surfaces of the side walls.
2 . The backlight module as claimed in claim 1 , wherein the elastic structures are elastic plates.
3 . The backlight module as claimed in claim 2 , wherein the elastic plates are oblique elastic plates.
4 . The backlight module as claimed in claim 3 , wherein the elastic plates intiltedly extend towards inner side of the frame.
5 . The backlight module as claimed in claim 3 , wherein each of the elastic plates together with the corresponding top surface of the side walls cooperatively define an acute angle.
6 . The backlight module as claimed in claim 5 , wherein the acute angle varies in the range from 1 degree to 60 degrees.
7 . The backlight module as claimed in claim 2 , wherein the elastic plates and the side walls are integrated into one body.
8 . The backlight module as claimed in claim 2 , wherein each of the elastic plates is in the form of a separate body with the frame.
9 . The backlight module as claimed in claim 2 , wherein each of the elastic plates is an arc-shaped elastic plate.
10 . The backlight module as claimed in claim 9 , wherein each of the elastic plates intiltedly extends toward inner side of the frame.
11 . The backlight module as claimed in claim 2 , wherein the elastic plates are symmetrically located at two opposite side walls.
12 . The backlight module as claimed in claim 2 , wherein the elastic plates slant upwards from the top surfaces of the side walls.
13 . The backlight module as claimed in claim 1 , wherein the frame is made of plastic.
14 . A liquid crystal display, comprising:
a liquid crystal display panel; and
a backlight module having a frame, the frame comprising:
a plurality of side walls; and
a plurality of elastic structures extending from top surfaces of the side walls for supporting the liquid crystal display panel.
15 . The liquid crystal display as claimed in claim 14 , wherein the elastic structures are elastic plates.
16 . The liquid crystal display as claimed in claim 15 , wherein the elastic plates are oblique elastic plates.
17 . The liquid crystal display as claimed in claim 16 , wherein each of the elastic plates together with the corresponding top surface of the side walls cooperatively define an acute angle varying in the range from 1 degree to 60 degrees.
18 . The liquid crystal display as claimed in claim 14 , wherein the elastic structures support the liquid crystal display panel in a thickness direction of the liquid crystal display.
19 . The liquid crystal display as claimed in claim 14 , wherein the backlight module further comprises a light guide plate, the side walls of the frame being joined end to end and cooperatively forming another space for receiving the light guide plate.
20 . The backlight module as claimed in claim 14 , wherein the elastic plates and the side walls are integrated into one body.
