Description

technical field [0001] The present invention relates to the technical field of display devices, and more particularly, to an outdoor display screen with an air purification function. Background technique [0002] Outdoor display screens are exposed to the natural environment and experience wind and sun, dust adhesion, and rain spraying, and it is very easy to accumulate dust and rain. Especially the display screens installed on the roof or the side of high-rise buildings are subject to strong wind and dust. Or when the haze passes through the display, it is easy to stick to the front of the display, causing the display to be blurred; also, the road is very dusty, and the display on the roadside is also prone to dust accumulation, which affects the display effect. Due to the influence of dust accumulation and rain spray, outdoor display screens require frequent maintenance, which requires a lot of work and high costs. [0003] The outdoor display screen stands in the natural...

Problems solved by technology

[0002] Outdoor display screens are exposed to the natural environment and experience wind and sun, dust adhesion, and rain spraying. It is very easy to accumulate dust and rainwater. Especially the display screens installed on the roof or on the side of high-rise buildings are subject to strong wind and dust. Or when smog passes through the display, it is easy to adhere to the front of the display, causing the display to be blurred; similarly, the dust on the road is very large, and the display on the roadside is also easy to accumulate dust and affect the display effect

Due to the impact of dust and rain spray, outdoor display screens need frequent maintenance, heavy workload and high cost
