摘要： 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.

摘要： The present invention teaches a backlight module and the LCD device. The backlight module includes a light guide plate and a light source located at a distance to a side of the light guide plate. The light source includes a substrate, multiple LED chips disposed on the substrate, multiple primary lenses disposed on the substrate corresponding to the LED chips, and multiple condenser lenses disposed on the substrate corresponding to the primary lenses. Each primary lens is disposed correspondingly to a LED chip, focuses light from the LED chip, and prevents the light emission face of the LED chip from being higher above the light guide plate, thereby enhancing the light coupling efficiency and reducing leakage of the backlight module. Each condenser lens is disposed correspondingly to a primary lens to further narrow light emission angle of the LED chip, enhancing light utilization efficiency.

摘要： 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.

摘要： A liquid crystal display device includes a display panel; a base utilized to support the display panel; and a split-type backlight module disposed corresponding to an incident surface of the display panel. The split-type backlight module includes a backplate, a light source plate, a diffusion plate, and an optical film. Light emitted from the light source plate passes through the diffusion plate and the optical film to form a uniform surface light source projected onto the display panel.
