Both have the disadvantage of not being able to update the advertising information in real time. When the information needs to be updated, it is necessary to manually paste a new poster or re-record a new picture and then fix it in the LED. Both have the defects of labor-intensive and inconvenient replacement.
The paraboloid-shaped reflective surface brings a series of defects, such as not being able to effectively integrate with the existing flat-shaped advertising display screen, and the parabolic-shaped reflective surface requires high processing precision, large volume, and expensive cost

Embodiment Construction
[0035] Light, as a kind of electromagnetic wave, when it passes through glass, because the wavelength of light is much larger than the size of atoms, we can use the overall parameters of the glass, such as the refractive index, rather than the detailed parameters of the atoms that make up the glass to describe The response of glass to light. Correspondingly, when studying the response of materials to other electromagnetic waves, the response of any structure in the material whose scale is much smaller than the wavelength of the electromagnetic wave to electromagnetic waves can also be described by the overall parameters of the material, such as the dielectric constant ε and magnetic permeability μ. By designing the structure of each point of the material, the dielectric constant and magnetic permeability of each point of the material are the same or different, so that the overall dielectric constant and magnetic permeability of the material are arranged in a certain order, and ...

The invention discloses an advertisement display screen based on a metamaterial satellite antenna, which comprises a metamaterial satellite antenna system used for receiving satellite signals, as well as a display device used for displaying advertising information, wherein the metamaterial satellite antenna system comprises a tuner, a vertically placed panel metamaterial and a reflecting plate located on the rear surface of the panel metamaterial; the panel metamaterial comprises multiple metamaterial sheet layers; and each metamaterial sheet layer comprises a substrate and artificial microstructures periodically distributed on the substrate. According to the advertisement display screen, the metamaterial principle is used to prepare the panel satellite antenna to enable the satellite antenna to be well integrated with the conventional advertisement display device, so that the advertisement display device can change display frames in real time according to the satellite signals, and manually detaching the device for fixedly arranging a new frame again can be omitted. Meanwhile, the advertisement display screen based on the metamaterial satellite antenna is simple in preparation technology, low in cost, small in size and convenient to mount and maintain.
Description
technical field [0001] The invention relates to an advertisement display screen, in particular to an advertisement display screen based on a supermaterial satellite antenna. Background technique [0002] At present, advertising display screens are usually erected beside highways, rivers, and tracks to display product advertising information or manufacturer information. Existing advertising display screens usually adopt two methods: one is to display advertising information through large posters, and the other is to display advertising information by repeatedly playing text information or picture information in the LED display screen. Both of them have the disadvantage of not being able to update the advertising information in real time. When the information needs to be updated, it is necessary to manually paste a new poster or re-record a new picture and then fix it in the LED. Both of them have the defects of labor-intensive and inconvenient replacement. At the same time, ...
