Abstract
Description
Technical Field
[0001] This utility model relates to the field of wireless conductive technology, and more specifically, to a wireless conductive billboard based on a metal mesh. Background Technology
[0002] In today's advertising signage industry, traditional illuminated signs typically rely on electrical wires for power. This not only results in exposed wires, affecting the aesthetics of the sign, but also involves complex manufacturing processes and high maintenance costs, especially in complex installation environments such as building facades and glass shop windows, where wire installation becomes particularly cumbersome. Furthermore, traditional wired power supply methods are susceptible to damage from external environmental factors such as rain and sandstorms, increasing maintenance frequency and costs. Therefore, the industry has gradually developed a demand for more aesthetically pleasing and convenient wireless power supply solutions. Wireless conductive signs have emerged to meet this need, especially wireless conductive glass illuminated signs, which, as a new form of advertising, offer advantages such as no exposed wires, easy installation, and overall aesthetic appeal. This new type of signage is now widely used in various settings such as shop windows, store signs, and architectural decorations, solving the aesthetic problems of traditional illuminated signs by eliminating the need for exposed wires.
[0003] However, most existing wireless conductive illuminated signs rely on traditional conductive materials such as indium tin oxide (ITO). While these materials possess some conductivity, they exhibit several shortcomings in practical applications. First, ITO has limited conductivity, especially under low-voltage power supply conditions, often resulting in uneven brightness and "dark areas" in the illuminated signs. Second, ITO has low mechanical strength, making it fragile and susceptible to environmental influences. Utility Model Content

Metal mesh electrodes, with their excellent conductivity, corrosion resistance, and high mechanical strength, are gradually becoming the preferred material for the conductive layer in wireless conductive billboards. Compared to traditional conductive materials such as ITO, metal mesh not only provides efficient current transmission with low resistance, ensuring uniform brightness and no dark areas in illuminated signs, but its conductive layer also has high light transmittance, ensuring a clear and bright display without affecting the billboard's transparency. Furthermore, the mechanical flexibility of the metal mesh allows it to adapt to the needs of billboards of different shapes and sizes.

The metal mesh conductive layer is made of a highly conductive, flexible, and corrosion-resistant metal with extremely low resistance. In the circuitry of the illuminated characters, power loss is significantly reduced, ensuring the overall brightness uniformity of the illuminated characters. Simultaneously, this highly conductive, low-resistance material allows the billboard to maintain stable current transmission even in large-area applications, thus achieving efficient energy utilization. Furthermore, it possesses good corrosion resistance and mechanical strength, maintaining stable performance over long-term use.
