    Abstract: Disclosed is a backlight module and a display module. The backlight module includes a backboard, a light bar, and an atomization layer. The backboard includes a bottom board, a plurality of side boards connected to the bottom board, and a top board connected to the plurality of side boards, and the plurality of side boards are enclosed to define a receiving chamber of the backboard. The light bar is located in the receiving chamber and is fixed at one side of the bottom board facing the top board. The atomization layer is located in the receiving chamber and is fixed at one side of the top board facing the bottom board. The atomization layer is capable of replacing the diffuser plate and the optical film in the current backlight module, thereby reducing the cost of the optical film and the diffuser plate.

    Abstract: Provided are a direct type backlight module and a liquid crystal display device. The direct type backlight module comprises: a back frame, a backlight source disposed in the back frame and an optical frame disposed relatively spaced from the backlight source; a top edge and two side edges of the back frame are respectively and fixedly connected with a top edge and two side edges of the optical film, and a bottom edge of the back frame is elastically connected with a bottom edge of the optical film. By elastically connecting the bottom edge of the back frame and the bottom edge of the optical film, the optical film is flattened by an elastic force generated by the elastic connection to avoid the collapse of the optical film. Thus, the diffuser can be eliminated and the thickness of the backlight module can be decreased to lower the production cost.

    Abstract: The present disclosure relates to a direct-type backlight module and a liquid crystal display. the direct-type backlight module includes a back frame, a backlight source, optical films and the elastic rope. The install pillars are arranged on the first edge and the second edge opposite to the first edge of the back frame. The backlight source is arranged within the back frame. The elastic rope and the install pillars cooperatively defines the supporting net opposite to the backlight source. The optical films are arranged on the supporting net, and thus may be supported by the supporting net. In this way, the optical films may be prevented from collapse, so as to exclude the diffusion plate. Not only the cost of the manufacturing process may be reduced, and the thin design of the backlight module may be realized.
