The invention relates to the technical field of display screens and discloses a large outdoor display screen with a purification function. The large outdoor display screen comprises a display screen body and is characterized in that an air purification structure is arranged in the accommodating cavity of the display screen body; the front end of the display screen body is provided with a display screen, an air inlet gap is formed in the display screen, the rear end of the display screen body is provided with air outlets; the air purification structure comprises a pre-filtering layer, an electrode layer and a composite filtering layer which are sequentially arranged along an extending direction from air inlet to the air outlets the pre-filtering layer is used for filtering large particles in the air, the electrode layer is used for adsorbing charged particles in the air, and the composite filtering layer is used for adsorbing small particles in the air; air guide channels are arranged in the electrode layer, electrode plates are adhered to the inner walls of the air guide channels, the air guide channels are arranged in an extending direction from the air inlet to the air outlets and penetrate the electrode layer. The large outdoor display screen has the advantages that the air enters the air purification structure under the flow guide effect of an exhaust fan and flows in a circulating manner in the air purification structure so as to be purified, and the large outdoor display screen is good in purification effect, capable of avoiding city land occupation when being arranged in a city, capable of being popularized and used and capable of effectively purifying city air pollution.
Description
technical field [0001] The invention relates to the technical field of display screens, in particular to large outdoor purification display screens. Background technique [0002] The display screen is a display tool that displays a certain electronic file on the screen through a specific transmission device and then reflects it to the human eye. [0003] At present, the display screens installed outdoors are generally used to broadcast advertisements, road signs and other information, which brings great convenience to our life. By placing the display screen in the air or attaching it to the wall, the display screen is greatly reduced. The floor area of the screen is reduced, saving land resources. [0004] However, these outdoor display screens are generally located in urban areas with a large population, and the locations where large outdoor display screens are installed are places with a large population, and the air quality in these places is extremely poor, which is h...
