Abstract
Description
Technical Field
[0001] This utility model relates to the field of rotating displays, and more specifically, to a toner-resistant structure for rotating display devices. Background Technology
[0002] Rotating display devices are becoming increasingly common in society, with many shopping malls, airports, and service areas using them for commercial advertising. Due to their rotating nature, these devices typically consist of a rotating part and a fixed part. Continuous power supply is a critical issue for rotating devices, and carbon brush slip rings are a widely used power supply structure. The internal structure of a carbon brush slip ring uses carbon brushes in contact with a copper ring for power supply, offering a long lifespan and the ability to transmit a relatively large current. Holographic screens require infrared photodiodes for signal transmission, consisting of a transmitter and a receiver. These two photodiodes communicate through a central hole. However, because the carbon brushes and slip rings supply power through contact, prolonged friction between the graphite brushes generates carbon dust. This carbon dust contaminates the light guide column, affecting light transmittance and causing abnormal signal transmission. Summary of the Invention
