Abstract

An LED screen includes a back shell, for containing a power source and a master control board, wherein the power source supplies electricity to the master control board; an LED module mounted on the back shell through a first fixer, and connected to the master control board, wherein the LED module comprises a display face, the master control board controls the LED module, so as to display through the display face; a decoration baseboard provided around the LED module and mounted on the back shell through a second fixer, wherein the display face of the LED module is not blocked; and a decoration board mounted on the back shell through a third fixer, wherein the display face of the LED module is not blocked; meanwhile, the decoration board blocks the fixers, in such a manner that the first fixer, the second fixer and third fixer are not externally visible.

Claims

1. An LED screen, comprising:

a back shell (9), for containing a power source (8) and a master control board (15);

an LED (Light Emitting Diode) module (5) mounted on the back shell (9) through a first fixer, and connected to the master control board (15), wherein the LED module (5) comprises a display face (20), the master control board (15) controls the LED module (5), so as to display through the display face (20), wherein the power source (8) supplies electricity to the master control board (15) and the LED module (5);

a decoration baseboard (3) provided around the LED module (5) and mounted on the back shell (9) through a second fixer, wherein the display face (20) of the LED module (5) is not blocked by the decoration baseboard (3); and

a decoration board (1) mounted on the decoration baseboard (3) through a third fixer, wherein the display face (20) of the LED module (5) is not blocked by the decoration board (1);

meanwhile, the decoration board (1) blocks the first fixer, the second fixer and the third fixer, in such a manner that the first fixer, the second fixer and third fixer are not externally visible.

2. The LED screen, as recited in claim 1, wherein the LED module (5) is mounted on a plurality of module installation boards (6) through a plurality of first tapping screws (4), and the module installation boards (6) are mounted on the back shell (9) through a plurality of module mounting bolts (7).

3. The LED screen, as recited in claim 1, wherein the decoration baseboard (3) is mounted on the back shell (9) through a plurality of second tapping screws (2).

4. The LED screen, as recited in claim 1, further comprising a button panel (14), which is embedded in the back shell (9), wherein the button panel (14) comprises a plurality of buttons (19) exposed on an external surface (21) of the back shell (9).

5. The LED screen, as recited in claim 1, further comprising a power switch (13) mounted on an external surface (21) of the back shell (9), wherein the power switch (13) controls the power source (8) to supply the electricity to the master control board (15).

6. The LED screen, as recited in claim 1, further comprising an indicator light (16) mounted on an external surface (21) of the back shell (9), for displaying a working state of the LED screen.

7. The LED screen, as recited in claim 1, further comprising a wire inlet port (17), in such a manner that an external wire is connected to the power source (8) or the master control board (15), wherein a wire sleeve (12) is provided at the wire inlet port (17), for protecting the external wire.

8. The LED screen, as recited in claim 1, further comprising a plurality of belt bolts mounted on the back shell (9), for connecting a belt for lifting the LED screen.

9. The LED screen, as recited in claim 1, further comprising a nut (11) in conjunction with a bolt, for mounting the master control board (15) on the back shell (9).

10. The LED screen, as recited in claim 1, further comprising a luminance sensor (18) mounted on the decoration board (1), wherein the luminance sensor (18) is connected to the master control board (15), for sensing an external environment luminance and sending a sensing signal to the master control board (15);

the master control board (15) treats the sensing signal for adjusting a display brightness of the LED module (5).
