Frameless liquid crystal display device

A frameless liquid crystal display device, comprising a rear enclosure, a backlight module arranged inside the rear enclosure, a mold frame arranged on the backlight module and fixedly coupled to the rear enclosure, a liquid crystal display panel arranged on the mold frame, and a surface decoration arranged at a lower end of the liquid crystal display panel and mounted to the mold frame, the liquid crystal display panel being coupled to the mold frame by a plurality of coupling sections, each of the coupling sections comprising a rectangular plate, an engagement section, and a connection section that connects the rectangular plate and the engagement section, the mold frame forming corresponding retention slots that correspond respectively to the coupling sections, each of the retention slots comprising a first opening, a second opening located below the first opening, and a channel communicating with the first and second openings, the first opening being greater than the second opening, whereby in assembling, the rectangular plates of the coupling sections are bonded to the liquid crystal display panel and the engagement sections of the coupling sections are first put through the first openings of the retention slots of the mold frame to be located at an upper end of the channels and are then moved down to a lower end of the channels so that the connection sections of the coupling sections are respectively received in and retained by the second openings of the retention slots to mount the liquid crystal display panel to the mold frame;

• wherein the plurality of coupling sections is uniformly distributed in non-displaying zones at an upper end portion and a lower end portion of the liquid crystal display panel;
• wherein the mold frame is fixed to the rear enclosure by screws;
• wherein the surface decoration is fixed to the mold frame by screws;
• wherein a cushioning pad is arranged between the liquid crystal display panel and the mold frame;
• wherein the liquid crystal display panel comprises a color filter (CF) substrate and a thin film transistor (TFT) substrate laminated on the CF substrate, a step being formed between the CF substrate and a lower edge of the TFT substrate, the surface decoration being positioned on and holding down the step and being mounted to the mold frame;
• wherein a top face of the surface decoration and a top face of the CF substrate are located on a same plane and a cushioning structure is arranged between the surface decoration and the liquid crystal display panel;
• wherein the liquid crystal display panel comprises liquid crystal interposed between the CF substrate and the TFT substrate and a top polarization plate and a bottom polarization plate respectively laminated to the CF substrate and the TFT substrate;
• wherein the backlight module comprises a backplane, a backlight source arranged inside the backplane, a reflector plate arranged inside the backplane, a light guide plate positioned on the reflector plate, and an optic film assembly positioned on the light guide plate;
• and
• wherein the backplane comprises a bottom board and a side board connected to the bottom board, the backlight source being mounted to the side board, the reflector plate being arranged on the bottom board, a heat dissipation board being arranged between the backlight source and the side board of the backplane, the backlight source being attached to the heat dissipation board, the heat dissipation board being attached to the side board of the backplane so as to fix the backlight source to the side board of the backplane.
