Abstract: This application discloses diaphragms, backlight modules and display devices. According to an example of the present application, a diaphragm includes a diaphragm body; and diaphragm lugs located on edges of the diaphragm body and each having a diaphragm lug hole. The diaphragm lug hole includes a first wall and a second wall opposite to each other. The first wall includes a first protrusion, and the second wall includes a second protrusion. The first protrusion and the second protrusion are arranged in a staggered manner, and a difference between a distance of a top portion of one of the first protrusion and the second protrusion from a wall opposite to the one of the first protrusion and the second protrusion, and a height of another one of the first protrusion and the second protrusion is less than or equal to 0.

Abstract: The present disclosure provides a backlight module and a display panel including the backlight module. The backlight module includes a back plate, a front housing and a membrane structure. The front housing is arranged in front of the back plate and coupled to the back plate. The membrane structure is arranged between the back plate and the front housing. A light-shielding structure is placed on at least one of the back plate and the front housing, the light-shielding structure on one of the back plate and the front housing abuts against the other one of the back plate and the front housing, and each light-shielding structure is arranged at a side of the membrane structure distal to a central axis of the backlight module, so as to shield light emitted by the membrane structure in a direction away from the central axis of the backlight module.
