Abstract

The embodiment of the invention discloses a display device, a backlight module and a frame unit. The frame unit comprises a rubber frame and a back plate which are matched with each other. The back plate consists of a bottom and a first side wall which are integrated as a whole, the bottom is used for bearing an optical diaphragm of the backlight module; the rubber frame consists of a bearing part, a second wall and a supporting part which are integrated as a whole, the bearing part is used for being matched with the bottom so as to fix the optical diaphragm and for supporting a liquid crystal panel, a holding channel is formed between the second side wall and the supporting port, the first side wall is arranged in the holding channel, the supporting part consists of a supporting main body and a positioning block which are integrated as a whole, the supporting main body is connected with the bearing part, and the positioning block and the bottom are matched with each other so as to prevent the rubber frame from doing translation motion relative to the back plate. With the invention, the stability and firmness of the rubber frame can be effectively improved, the display property of the display device is stable, the condition of product damage does not occur easily, and the service life of the product can be further prolonged.

Description

technical field [0001] The invention relates to the technical field of liquid crystal display, in particular to a backlight module and its frame unit, and also to a display device using the backlight module. Background technique [0002] In the prior art, the frame unit of the backlight module includes a plastic frame and a backplane, and the glue frame and the backplane are connected and fixed through side walls. [0003] Specifically, the plastic frame is provided with side walls, and correspondingly, the back plate is provided with side walls. When mating, the side walls of the plastic frame and the side walls of the back plate can be fixedly connected by snap connection or screw connection. However, only through snap-fit ​​connection and screw connection, the plastic frame is easy to loosen and shake, resulting in poor stability of the plastic frame. [0004] In addition, if the extension of the plastic frame is provided to support the liquid crystal panel, a bump can b...
