2 . The backlight module according to claim 1 , wherein the cover is of a plate-type structure.

3 . The backlight module according to claim 2 , wherein an adhesive overflow groove is disposed on an upper surface of the cover.

4 . The backlight module according to claim 1 , wherein an adhering layer is disposed on a lower surface of the cover.

5 . The backlight module according to claim 4 , wherein the adhering layer corresponds to a non-display area of a liquid crystal panel.

6 . The backlight module according to claim 5 , wherein the adhering layer is a double-sided adhesive tape.

7 . The backlight module according to claim 1 , wherein a protruded platform is disposed at an inner side of the frame close to the middle part of the backlight module, and a first supporting elastomer is disposed on the lowersurface of the cover and a position of the first supporting elastomer corresponds to the protruded platform.

8 . The backlight module according to claim 7 , wherein a second supporting elastomer is disposed on a surface of the protruded platform, and the liquid crystal panel is arranged between the first supporting elastomer and the second supporting elastomer.

9 . The backlight module according to claim, wherein a first protruded platform and a second protruded platform are disposed at an inner side of the frame close to the middle part of the backlight module, and a first supporting elastomer is disposed on the lower surface of the cover and a position of the first supporting elastomer corresponds to the first protruded platform.

10 . The backlight module according to claim 9 , wherein a second supporting elastomer is disposed on a surface of the first protruded platform, and the liquid crystal panel is arranged between the first supporting elastomer and the second supporting elastomer.

11 . The backlight module according to claim 7 , wherein the first supporting elastomer is an adhesive tape.
