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.

The present invention provides a backlight module having a backplate, a position-limiting unit, a reflective sheet, a light guiding plate, and a light-emitting unit. The position-limiting unit is disposed on the backplate and has a position-limiting surface, a guiding surface, and a gap. The reflective sheet is disposed on the backplate and has a first side edge, a second side edge, a cutting line extending inward from the first side edge, and a bendable portion formed between the cutting line and the second side edge. The bendable portion abuts the position-limiting surface of the position-limiting unit and is guided by the guiding surface to extend into the gap as the reflective sheet expands along the position-limiting surface. The present invention also provides a display device having aforementioned backlight module and a display panel.

A frame structure includes a back frame and a fixing frame combined on the back frame. The fixing frame includes multiple buffering zones, and each of the buffering zones has an upper extension and a lower extension. The upper extension and the lower extension are spaced apart from each other along a first axis without contacting each other and extending toward each other along a second axis. The first axis is not parallel to the second axis. The deformation of the fixing frame can be absorbed when it expands by utilizing the design that the upper extension and lower extension of each buffering zone without contacting with each other. It can avoid the possibility of the fixing frame warping or falling off from the back frame due to thermal expansion, thereby prolonging the service life of the frame structure. The present invention also provides a backlight module and a display device including the frame structure.

A frame assembly has a front side, a back side, at least one first assembly and a second assembly. The first assembly has multiple assembling portions disposed at spaced intervals. The second assembly has multiple engaging portions disposed at spaced intervals, and each one of the multiple engaging portions has two engaging surfaces disposed at a spaced interval, a bottom surface connected with the two engaging surfaces, and an opening opposed to the bottom surface and located on an outer edge of the second assembly. A width between the two engaging surfaces near the opening is smaller than a width near the bottom surface. Locations of the multiple engaging portions correspond to locations of the assembling portions, and multiple assembling portions and the multiple engaging portions are capable of being engaged together. A backlight module and a display device are also provided.

A backlight module comprises an outer frame unit, a light guide plate arranged in the outer frame unit, a light-emitting unit, a plurality of adhesives for fixing the light-emitting unit on the light guide plate, and a plurality of abutting structures. The light-emitting unit includes a flexible circuit board and a plurality of light-emitting elements arranged on the flexible circuit board at intervals. Part of the flexible circuit board is deformed at a specific position by the abutting structures, and the position of the light-emitting elements relative to the light guide plate can be adjusted. Thereby, the light-emitting elements can be aligned with the light incident surface of the light guide plate, prevent light from leaking from the light emitting surface of the light guide plate close to the light-emitting elements, and reduce the generation of bright lines and improving the overall uniformity. The present invention also provides a display device including the backlight module.

The frame assembly has a first direction and comprises a first frame, which has at least one exhausting passage, an adhesive layer, which has at least one through hole, and a second frame, which is connected to the first frame via the adhesive layer. A containing space is defined by the first frame and the second frame together and extends along the first direction. The exhausting passage fluidly communicates with the containing space and the external environment. The adhesive layer is disposed inside the containing space to divide the containing space into two venting passages that fluidly communicate with each other through the through hole. Residue air in the containing space is evacuated through the exhausting passage, increasing an adhered area and adhesion completeness of the adhesive layer, thereby increasing an adhesion-bonding strength of the two frames and structural stability of the frame assembly.

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.

A frame device includes a first frame, a plurality of fasteners and an second frame. The first frame includes a base wall and a side wall extending transversely from one end of the base wall. The fasteners are disposed on the side wall opposite to the base wall. The second frame is assembled to and covers an upper end of the first frame and has a plurality of spaced-apart positioning holes. A portion of each fastener passes out of a respective positioning hole and presses against the second frame when the second frame is assembled to the first frame.
