Backlight module and display device

A backlight module, comprising a back plate and an assembled light plate, wherein the assembled light plate is made up of a plurality of light plates, and wherein a gap is defined between every two adjacent light plates;

• wherein backlight module further comprises a pressure bar, and the assembled light plate is fixed to the back plate through the pressure bar;
• wherein the pressure bar comprises a fixing portion and a connecting portion, and wherein one end of the connecting portion passes through the gap, and the other end is connected to the fixing portion;
• wherein the fixing portion extends from the gap to the light plates on both sides to form a first abutting portion and a second abutting portion, wherein surfaces of the first abutting portion and the second abutting portion adjacent to the respective light plates are level and flush with each other;
• wherein the first abutting portion and the second abutting portion respectively abut and firmly press light emitting surfaces of the light plates on both sides;
• wherein the fixing portion covers the entire gap;
• wherein a light supplementation structure is arranged on a surface of the fixing portion away from the connecting portion;
• wherein the pressure bar further comprises a plurality of lamp beads that are arranged on the fixing portion and are uniformly arranged on a surface of the fixing portion away from the connecting portion along a length of the gap.
