Description
Technical Field
The invention relates to the technical field of display, in particular to a frame structure and a display device.
Background
The design mode of the traditional CCFL (Cold Cathode Fluorescent Lamp) television is to install a loudspeaker, a remote control board and a key board on a front shell of the television, fixedly install a main board and a power board of the television on a module backboard, and arrange a rear shell outside the module backboard to protect the main board and the power board of the television.
In order to make a television (other display devices such as a display and the like) ultrathin, the traditional liquid crystal television omits a front shell and a rear shell of the television, uses a front frame of a display module as the front shell, and uses a back plate as the rear shell of the television, so as to reduce the components of the television and make the television thinner. The power panel and the mainboard are continuously installed on the backboard, a protective cover is additionally arranged outside the power panel and the mainboard, the effect of the protective cover is similar to that of a rear cover of a television, and the conventional common module backboard component is also formed.
At present, ultra-thinning is one of the main development directions of display devices, and the thin, light and large display devices have higher requirements on the structural strength, wherein the module backboard mainly influences the structural strength.
In order to improve the structural strength of the module backboard, the conventional display device usually adopts a thicker module backboard and/or integrally forms a reinforcing rib on the module backboard; however, increasing the thickness of the module backplane increases the product cost, and adding the reinforcing ribs interferes with the layout and fixation of the internal components of the display device.
In order to solve the above technical problem, the prior art provides a module backplane assembly, as shown in fig. 1, which includes a module backplane 10, a stiffener 20, and a base 30.

The base 30 is disposed at the bottom of the module back plate 10, and the reinforcing ribs 20 include first reinforcing ribs 21 disposed corresponding to the base 30, and second reinforcing ribs 22 disposed horizontally. Therefore, the strength of the module backboard can be prevented from being increased by thickening the backboard material, and the production cost is reduced; also need not to design concave-convex structure's strengthening rib and increase the intensity of module backplate when the module backplate shaping (be connected strengthening rib 20 and module backplate 10 respectively the shaping back, integrated into one piece no longer), can avoid interfering the overall arrangement and the fixing of the inside spare part of TV set (the strengthening rib deviates from the optical diaphragm, consequently, does not interfere the overall arrangement and the fixing of the inside spare part of TV set).
