The present invention relates to a display, and more particularly to a frameless display.

In the conventional liquid crystal display, the structural shell of the display is designed separately from the display module thereof, so that the number of components required for the entire device is large, and the structure is laminated, so that the width of the frame around the display area is difficult to be reduced. In the current frameless liquid crystal display, the structural components of the display module also support the structural support of the device, so that the width of the frame can be reduced. For example, the back cover of the display directly connects with the side surface of the plastic frame of the liquid crystal panel, and for example, the back cover of the display is connected to the rear side of the display module through another connecting member. In the former case, the width of the frame includes the thickness of the back shell in addition to the thickness of the frame, and it is obvious that the frame width of the frame has a reduction limit; in the latter, the additional independent connector will increase the complexity of the device assembly.

In view of the problems in the prior art, it is an object of the present invention to provide a display in which the outer back shell is directly joined using the original structural members of the display module.

The display of the present invention comprises an outer back shell and a display module. The outer back shell includes a first joint. The display module has a display side and a rear side opposite to the display side. The display module includes a metal plate back shell on the rear side, and the metal board back shell includes a back board portion, and the back board portion A portion of the bend protrudes from the rear side to form a second engagement portion. The outer back shell and the display module are coupled to each other via the first connecting portion and the second connecting portion.

Compared with the prior art, the outer back shell of the display of the present invention does not need to be connected to the side surface of the frame of the display module, so it can have a smaller display side border width. In addition, the outer back shell can be connected to the rear side of the display module without additional independent connectors, without increasing the assembly of the device. the complexity.
