In addition, the panel body usually adopts a direct type backlight module as its backlight structure, and in order to achieve good backlight effect and structural stability, the conventional direct type backlight module generally needs to adopt a plurality of supporting columns to support the diffuser plate. The common support columns are made of PC and PMMA materials, are generally transparent or white and are different in shape, but the support columns made of any material have the defects, shadows are easily generated at the support columns, particularly when the size of the direct type backlight module is smaller, the shadows of the support columns are more obvious, more optical films are needed for shielding, and the cost of the backlight module is increased. In addition, the conventional direct-type display has a relatively large thickness of the screen body due to the relatively long distance between the diffusion plate and the back plate.

As shown in fig. 1 to 7, 10, 11 and 13 (reference numerals refer to fig. 1 to 20 in all embodiments of the present disclosure), an embodiment of the present disclosure provides a display main body 10 applied to a tiled smart interactive flat panel, where the display main body 10 includes a display module and a bezel assembly 5, the display module includes a backplane 1, and a diffuser plate 2, an optical film 3 and a cover plate 4 sequentially disposed on one side of the backplane 1, the bezel assembly 5 is disposed on a periphery of the display module, the backplane 1 is disposed at a distance from the diffuser plate 2, a light source assembly 6 is disposed on one side of the backplane 1 close to the diffuser plate 2, the light source assembly 6 abuts against the diffuser plate 2, at least one tiled side and a non-tiled side are disposed on the periphery of the display module, the bezel assembly 5 includes a first bezel 501 disposed on the tiled side and a second bezel 502 disposed on the non-tiled side, the edge of the optical film 3 adjacent to the splicing side is sandwiched between the first frame strip 501 and the cover plate 4, the edge of the optical film 3 adjacent to the non-splicing side is provided with a hanging hole 302, and the second frame strip 502 is provided with a hanging column 504 inserted into the hanging hole 302. By abutting the light source assembly 6 against the diffusion plate 2, the diffusion plate 2 can be supported by taking the light source assembly 6 as a supporting structure of the diffusion plate 2, so that the use of supporting columns is omitted, the backlight and display effects are improved, the distance between the diffusion plate 2 and the back plate 1 is only the thickness of the light source assembly 6, and the overall thickness of the display main body 10 is greatly reduced; the optical film 3 is fixed on the display main body 10 in a clamping and hanging combined mode, and the clamping side is positioned on the splicing side of the display main body 10, so that a suspension column 504 is prevented from being arranged on the splicing side, the width of a non-display area on the splicing side after splicing is reduced, and the display effect is improved; by arranging the suspension posts 504 for suspending the optical film 3 on the second frame strips 502, the optical film 3 can be prevented from being suspended on the back plate 1, a pressing frame for pressing the optical film 3 is omitted, and a wider display area can be formed after the pressing frame is omitted, that is, a non-display area at the second frame strips 502 is reduced.

Present straight following formula backlight unit hangs the optical film on the backplate, the pressure frame compresses tightly the optical film on the backplate, consequently, the pressure frame certainly has the part to set up the one side that is close to the apron at the optical film, the apron is transparent toughened glass, this pressure frame sees through the apron very easily and shows, in order to reduce the probability that the pressure frame shows, need set up more diaphragms and shelter from, manufacturing cost has been increased, and because the blocking of pressure frame, still can reduce the display area who shows the main part, the non-display area who shows the main part edge has increased promptly, the display effect has greatly been reduced. And the optics diaphragm 3 of this scheme hangs on second frame strip 502 for there is not this type of structure of pressure frame in the region between optics diaphragm 3 and the apron 4, and through sheltering from of optics diaphragm 3 and diffuser plate 2 layer upon layer, can hide the structure that is located diffuser plate 2 and keeps away from optics diaphragm 3 completely, and need not additionally increase the diaphragm and shelter from, has promoted display effect.

The toughened glass belongs to safety glass. The tempered glass is actually prestressed glass, and in order to improve the strength of the glass, a chemical or physical method is usually used to form compressive stress on the surface of the glass, and the glass firstly counteracts surface stress when bearing external force, so that the bearing capacity is improved, and the wind pressure resistance, the cold and hot property, the impact property and the like of the glass are enhanced.
