However, the advertising information or manufacturer information in this type of LCD screen is fixed in the LCD screen. If you want to replace the advertising information, you need to re-burn new advertising information, which cannot be replaced in real time.
[0003] In addition, the use occasions of this type of commercial liquid crystal display are too small to receive and broadcast satellite TV signals from satellites. Composed of a feed source and a high frequency head, the parabolic reflector is used to receive the weak signal from the satellite and converge it in the feed source and high frequency head at the focal point
The paraboloid-shaped reflective surface prevents it from being effectively integrated with the existing flat commercial liquid crystal display, and the parabolic-shaped reflective surface requires high machining accuracy, large volume, and expensive cost

Embodiment Construction
[0040] 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 a commercial liquid crystal display screen based on a metamaterial satellite antenna. The commercial liquid crystal display screen comprises a metamaterial satellite antenna system for receiving satellite signals and the liquid crystal display screen for displaying advertising information. The metamaterial satellite antenna system comprises a tuner, a flat metamaterial arranged vertically and a reflecting plate located at the back of the flat metamaterial, the flat meta material comprises a plurality of layers of metamaterial sheet layers, and each layer of the metamaterial sheet layers comprises a substrate and artificial microstructures distributed on the substrate periodically. According to the commercial liquid crystal display screen, the flat metamaterial satellite antenna is prepared by adopting a metamaterial principle, the flat metamaterial satellite antenna is integrated with an existing commercial liquid crystal display screen well so as to enable the commercial liquid crystal display screen to change display frames in real time according to the satellite signals, and commercial liquid crystal display screen can play the satellite signals. Simultaneously, the commercial liquid crystal display screen based on the metamaterial satellite antenna is simple in preparation process, low in cost, small in volume and convenient to install and maintain.
Description
technical field [0001] The invention relates to a commercial liquid crystal display, in particular to a commercial liquid crystal display based on a supermaterial satellite antenna. Background technique [0002] At present, commercial LCD screens are installed on the outer surfaces of various high-rise buildings in the city, mainly used to broadcast advertisements, such as the commercial LCD screens installed in Times Square in New York, and the commercial LCD screens installed on various high-rise buildings in pedestrian streets. These commercial LCD screens are mainly used to display product advertisement information or manufacturer information. However, the advertising information or manufacturer information in this type of liquid crystal display is fixed in the liquid crystal display. If you want to replace the advertising information, you need to re-burn new advertising information, which cannot be replaced in real time. [0003] In addition, the use occasions of this ...
