Abstract

Disclosed are a display screen and a display screen frame. The display screen includes a display screen frame and a plurality of display modules, the display screen frame includes a plurality of profile rods, the plurality of profile rods are distributed at a preset distance interval, an open slot on a same side surface of each profile rod is provided with a magnetic adsorption piece, and the display module is fixed on the magnetic adsorption piece.

First claim

What is claimed is:

1. A display screen, comprising:
a display screen frame; and
a plurality of display modules;
wherein the display screen frame comprises a plurality of profile rods, an open slot on a same side surface of each profile rod is provided with a magnetic adsorption piece, and the plurality of display modules are fixed on the magnetic adsorption piece;
wherein a back of each display module is fixed with a magnetic adsorption leveling plate, a first display module is magnetically fixed on the magnetic adsorption leveling plate of a second display module adjacent to the first display module, and both a back of the first display module and a back of the second display module are flush with a surface of a same magnetic adsorption leveling plate.

2. The display screen of claim 1 , wherein the open slot is a dual slot, a middle of the dual slot is provided with a positioning boss, and a surface of the positioning boss is in contact with a back of the display module.

3. The display screen of claim 1 , wherein the magnetic adsorption piece is a bar ferromagnetic material block, and the open slot on the same side surface of each profile rod is embedded with the bar ferromagnetic material block extending in a length direction of a corresponding open slot.

4. The display screen of claim 1 , wherein the magnetic adsorption piece is a bar magnet, and the open slot on the same side surface of each profile rod is embedded with the bar magnet extending in a length direction of a corresponding open slot.

5. The display screen of claim 4 , wherein two sides of the open slot on the same side surface of each profile rod are embedded with two L-shaped ferromagnetic pieces extending in the length direction of the corresponding open slot, and each bar magnet is provided between the two L-shaped ferromagnetic pieces of the corresponding open slot.

6. The display screen of claim 1 , wherein the magnetic adsorption piece is a magnetic adsorption fixer, the open slot on the same side surface of each profile rod is provided with a plurality of magnetic adsorption fixers, and each magnetic adsorption fixer corresponds to a magnetic point of the display module.

7. The display screen of claim 1 , wherein the plurality of profile rods are distributed at a preset distance interval along a side of the display screen frame.

8. The display screen of claim 1 , wherein the display screen frame further comprises a top crossbeam rod and a bottom crossbeam rod, top sides of the plurality of profile rods are connected by the top crossbeam rod, and bottom sides of the plurality of profile rods are connected by the bottom crossbeam rod.

9. The display screen of claim 1 , further comprising:
a plurality of electrical assemblies, each electrical assembly being firmly fixed on a lateral slot of each profile rod,
wherein the display screen frame further comprises a plurality of support plates for fixing the plurality of electrical assemblies, and a side of each support plate is firmly fixed on the lateral slot of each profile rod for installing and fixing at least one electrical assembly.
