A backlight module has a back plate having a supporting surface, a reflective sheet, a light source board, and at least one connecting structure. The reflective sheet is arranged on the supporting surface of the back plate along an assembling direction. The light source board is disposed between the reflective sheet and the back plate. The at least one connecting structure has a recess and a post. The recess has an opening and a guiding surface connected to the opening and inclined along a guiding direction relative to the supporting surface. The post has an end portion configured to pass through the opening of the recess and hook the guiding surface. The back plate and the reflective sheet are mounted via the recess and the post. A display device is also provided.

Backlight module and display device

A backlight module comprises a back plate, a reflective sheet arranged on the back plate and forming a plurality of openings, a plurality of light-emitting elements located in the plurality of openings, at least one optical element arranged on the reflective sheet, and at least a supporting element configured between the back plate and the reflective sheet. The supporting element can move along with the reflective sheet. The supporting element has a base portion and a supporting portion extending from the base portion towards the optical element. The base portion of the supporting element is located between the back plate and the reflective sheet. The supporting portion of the supporting element passes through the reflective sheet to support the optical element. The supporting element is not a fixed design and can move along with the reflective sheet. Therefore, other plates under the reflective sheet do not require openings, which can improve assembly convenience and effectively reduce the mechanism interference caused by the expansion and contraction of the reflective sheet. The invention also provides a display device including the backlight module.
