LED transparent screen signal transmission method [Copy link]

LED transparent screens have been widely used in leisure and civilization squares, wealthy business bases, commercial streets, railway stations, subways, shopping malls and other places. Due to the diversity and complexity of its application fields, higher requirements are also put forward for the stability, reliability and smoothness of audio and video signal transmission. The signal transmission methods used by LED display screens for single-screen broadcasting or network broadcasting are diverse. Common LED display screen signals are divided into wired signals transmitted by network cables, and wireless signals such as GPRS, 3G, and 4G. Classification of LED transparent screen signal transmission 1. Wireless transmission: There are two types of wireless transmission methods, one is WIFI mode and the other is mobile phone 4G mode. These two methods are called asynchronous control in the LED display screen control method. 2. Wired transmission: As the name implies, it is to be transmitted through a line. This line can be a network cable (category 5e or category 6e), a single-mode optical fiber, or a multi-mode optical fiber. The specific type of line to be used depends on the transmission distance. A network cable can be used for less than 100M; multi-mode optical fiber can be used for 100M-500M; and single-mode optical fiber can be used for more than 500M. What are the advantages and disadvantages of wired transmission and wireless transmission? 1. The wired transmission signal is stable and the screen display effect is better. The disadvantage is that if the distance is too far, the cost is high and the flexibility is poor. 2. Wireless transmission can ignore the cost brought by the distance and can achieve multi-point simultaneous control, but the signal is unstable and the traffic cost is high if the video transmission is too large. The specific signal transmission method to be used in the transparent LED display project is mainly determined by the specific situation of the project. Choose a better solution. If it is difficult to judge, it is recommended to find professionals from the LED transparent screen manufacturer to provide a system design plan.
