[0073] The radiator 500 is connected to the bottom of the display panel 100. The radiator 500 is in direct contact with the dot matrix screen 300 and is used to dissipate heat from the dot matrix screen 300. The radiator 500 is also used to enclose the dot matrix screen 300 and the light-emitting component 200 within the display panel 100, so that the radiator 500 can protect the dot matrix screen 300 and the light-emitting component 200 while dissipating heat from the dot matrix screen 300.

[0074] The display device provided by the embodiment of the present application includes: a display panel 100, a dot matrix screen 300, a light-emitting component 200, a decorative ring 400, and a radiator 500.
