Claim 17:
18. 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, and is made of a transparent material; wherein a reflective coating is coated on a surface of the fixing portion away from the connecting portion; the surface of the fixing portion away from the connecting portion is indented toward the back plate to form an arc structure;
wherein the backlight module further comprises an optical film and a support column, wherein the optical film is arranged on the side of the assembled light plate away from the back plate, wherein the support column is arranged between the optical film and the fixing portion, wherein one end of the support column is connected to the fixing portion, and the other end supports the optical film, wherein a depth of the support column connected to the fixing portion along a direction from the optical film to the back plate is adjustable; wherein a through slot is defined in the back plate at a position corresponding to the connecting portion, and a pressure bar fixing protrusion is arranged on the side of the back plate away from the assembled light plate; wherein the pressure bar fixing protrusion is arranged at a slot edge position of the through slot, and wherein the connecting portion passes through the through slot and is fixedly connected with a side surface of the pressure bar fixing protrusion; wherein the backlight module further comprises a buffer member that is disposed in the gap and between the connecting portion and the respective light plate;
wherein the fixing portion further comprises a main body structure, and a plurality of first protruding structures and a plurality of second protruding structures that are disposed on the main body structure, wherein the main body structure covers the gap, wherein the plurality of first protruding structures and the plurality of second protruding structures are respectively arranged on both sides of the main body structure, and wherein each of the plurality of second protruding portions is correspondingly disposed in a middle of two adjacent first protruding portions; wherein there is arranged a lamp bead between every two adjacent first protruding structures, and there is also arranged a lamp between every two adjacent second protruding structures;
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; wherein the lamp beads on the pressure bar and the support column are designed to avoid each other.
