[0024] Further explanation, the area ratio of the heat dissipation seat 31 on the back of the display screen body 1 is not less than 30%, so that the heat dissipation seat 31 can provide a large enough heat dissipation area for the display screen body 1, and ensure the heat dissipation effect.

[0025] Further explanation, the front of the heat dissipation seat 31 is paved with a silicone gasket 31a, and the area ratio of the silicone gasket 31a on the front of the heat dissipation seat 31 is not less than 90%, so that the silicone gasket 31a can fill the gap between the heat dissipation seat 31 and the display screen body 1, so as to improve the heat conduction efficiency.

[0026] Further explanation, the air outlet of the heat dissipation fan 35 is directly opposite to the heat dissipation seat 31, so that the airflow blown by the heat dissipation fan 35 can flow horizontally along the through slot formed between the heat dissipation fins 32, so as to quickly take away the heat on the surface of the heat dissipation seat 31, and realize high-efficiency heat dissipation.
