Especially when the partial area of the display screen assembly is located on the airflow flowing path of the ventilation part, the airflow flows into the shell from the ventilation part, hot air in the shell can be blown out, and the airflow can flow through the surface of the display screen assembly to exchange heat with the flowing display screen assembly, so that the display screen assembly is subjected to heat dissipation and temperature reduction, the temperature of the display screen assembly is further reduced, and the operability and sensitivity of the display screen body 10 are guaranteed.

Optionally, the ventilation part comprises an air inlet part 401 and an air outlet part 402 which are communicated; wherein the air inlet portion 401 and/or the air outlet portion 402 includes a plurality of air vents 403. As shown in connection with fig. 2 to 5.

Through the air inlet 401 and the air outlet 402 which are communicated, external air flows into the shell from the air inlet 401, flows out of the shell from the air outlet 402, and blows hot air in the shell out of the shell, so that the purpose of radiating and cooling in the shell is realized.

The term "communicating air inlet portion 401 and air outlet portion 402" is understood to mean that the two portions are communicated with each other in the airflow path, that is, the airflow flows in from the air inlet portion 401 and flows out from the air outlet portion 402.

Illustratively, in the case where the housing 40 has a square ring-shaped structure, the air inlet portion 401 is located at one of the side portions of the housing 40, and likewise, the air outlet portion 402 is located at one of the side portions of the housing 40.

Alternatively, the air inlet portion 401 may be one hollow structure of the side portion of the housing 40, and the air outlet portion 402 is another hollow structure of the other side portion of the housing 40. And the air flow is in and out through the hollow structure.

In the case of vertically mounting the display device, the air inlet portion 401 is provided at the bottom of the housing 40, and the air outlet portion 402 is provided at the top of the housing 40. According to the dynamics, the hot air within the housing moves upward and can be considered to be near the top of the housing 40. In this way, the air flow enters from the bottom of the casing 40, and then the hot air is blown out of the casing from the air outlet part 402 rapidly, so that the phenomenon that the hot air exchanges heat with the surface of the main board 20 again when flowing downwards is avoided, the temperature of the main board 20 is increased, and the heat dissipation and cooling effects are affected.
