Abstract: A backlight module and a display panel are provided. The backlight module includes a first engagement structure and a second engagement structure. By engaging the first engagement structure with the second engagement structure, a sealant and a bottom frame are fixed to each other to fix an optical film, thereby preventing the optical film from shifting and vibration scratches. Therefore, it is prevented to provide a positioning post for fixing the optical film on the light guide plate, and the applicability of a thermal-pressing process of the light guide plate is improved.

Abstract: The present disclosure provides a backlight module and a display panel, wherein the backlight module includes a backboard and a widening member, the widening member is disposed on at least one side of the outer frame opposite to the accommodation chamber and detachably connected to the outer frame. As such, when on-board display screens having a same visual area size but different appearance sizes are used, only the widening member needs to be changed to meet the requirements of the overall appearance size. The outer frame can be used in common, and thus a mold for the outer frame can be used in common, thereby significantly reducing the number of mold of the outer frame of the backlight module, and thereby reducing a cost of the backlight module.
