Abstract

The present disclosure provides a display device, including a housing, an air tunnel, and a functional device. The housing includes an air inlet and an air outlet, wherein the air inlet and the air outlet are disposed on two sides of the housing opposite to each other. The air tunnel is disposed in the housing and extends from the air inlet to the air outlet; and the functional device is disposed in the housing and located outside the air tunnel.

First claim

What is claimed is:

1. A display device, comprising:
a housing, comprising an air inlet and an air outlet, wherein the air inlet and the air outlet are disposed on two sides of the housing opposite to each other;
an air tunnel disposed in the housing and extending from the air inlet to the air outlet;
a first functional device disposed in the housing and located on an upper side of the air tunnel;
at least one partition plate disposed in the housing and located between the first functional device and the air tunnel; and
a second functional device disposed in the housing and located below the air tunnel, wherein the second functional device comprises a backlight module;
wherein the air tunnel is formed by a side of the partition plate toward the backlight module and a side of the backlight module toward the partition plate; and
wherein a surface roughness of the side of the partition plate toward the backlight module and a surface roughness of the side of the backlight module toward the partition plate are greater than Ra0.04.

2. The display device as claimed in claim 1 , further comprising:
a blower fan disposed on a terminal of the air tunnel close to the air inlet; and
an ejector fan disposed on a terminal of the air tunnel close to the air outlet.

3. The display device as claimed in claim 1 , further comprising:
a heat dissipation layer disposed on an inner wall of the air tunnel.

4. The display device as claimed in claim 1 , wherein the first functional device comprises a motor device, and wherein the second functional device comprises a display screen disposed on a side of the backlight module away from the air tunnel.

5. The display device as claimed in claim 4 , wherein the motor device comprises:
a sealed chamber provided on the air tunnel; and
a power plate and a core plate disposed in the sealed chamber.

6. The display device as claimed in claim 5 , wherein the motor device further comprises:
a heat dissipation fan disposed in the sealed chamber and facing the power plate and the core plate.

7. The display device as claimed in claim 4 , wherein the display screen comprises:
a liquid crystal display panel disposed on a side of the display screen away from the air tunnel.

8. The display device as claimed in claim 4 , further comprising a cover plate disposed on a display surface of the display screen.
