The bottom side end of the iron backplane radiator is a flanging structure, flanging from the back side to the whole surface, and the tail end is embedded between the liquid crystal panel and the glass light guide plate, and fits the glass light guide plate, being in the same plane as the film sheet. And the bottom side end of the iron backplane radiator protrudes towards both sides at the position close to the lamp bar, forming a heat dissipation space for the convenience of the lamp bar to dissipate heat.

[0006] One of the major inventive points of the present utility model lies in the fixation of the F-shaped frame.

More preferably, in an embodiment of the present utility model, the number of the bridge snap connections is 8; and the distance between the midpoints of the two bridge snap connections at both ends is 500 to 520 mm.

[0013] Furthermore, positioning snap connections are provided at the midpoints of the two bridge snap connections at both ends, and the rear shell is provided with blocks that cooperate with the positioning snap connections. To facilitate the positioning of the bridge snap connections, it is preferably designed with positioning snap connections in the present utility model, which are designed at the midpoint of the straight line where the bridge snap connections are located, improving the snap - fitting efficiency.

[0014] Furthermore, multiple groups of trapezoidal clamping columns are provided on the edge - wrapping part, and multiple snap - holes for clamping the trapezoidal clamping columns are provided at the bottom of the rear shell. Each group of trapezoidal clamping columns is divided into two, and the outer - facing side is in a slope shape, facilitating sliding into the snap - holes of the rear shell for quick fixation.
