Abstract: 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.

Abstract: 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.

Abstract: 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.
