The mysterious

In the bustling streets of the city or at the scene of large-scale events, we can always see those colorful and smooth LED displays. They are like the eyes of the city, conveying all kinds of information. But do you know? Behind these eye-catching, there is a silent hero behind the scenes-the receiving card. Today, let's unveil the mystery of the receiving card and have a deeper understanding of its important role in the LED display and its components.

The receiving card, as the name suggests, is a card that provides signal images to the LED display module. It is like a "signalist" responsible for converting the image data from the sending card into a signal that the LED display can understand, thereby driving the entire screen to present the vivid images we see.

Although the receiving card is small, its internal structure is quite sophisticated, mainly composed of the following parts:

1. Network port: The network port is an important interface for the receiving card to connect to external devices. It implements a series connection mode. Each receiving card is connected to other cards through a network cable to form a complete data transmission network. In this way, the image data can be smoothly transmitted from the sending card to each receiving card, and then further transmitted to the LED display module.

2. Power supply port: The power supply port is the energy input interface of the receiving card. It usually has an interface for a 5V line, as well as a VCC (positive) and GND (negative) socket. This socket is used to connect the power cord to provide a stable working voltage for the receiving card to ensure its normal operation.

3. Cable port: The cable port is a bridge between the receiving card and the LED display module. It is used to plug in the cable, one end of which is connected to the receiving card and the other end is connected to the LED display module. Through the cable port, the image signal can be accurately transmitted to each module, presenting a perfect picture effect. There are usually digital markings next to the cable port, such as JH1, JH2, etc. These numbers indicate the order of the cable. When installing the module, we need to connect the cable and the module in this order to ensure the correct display of the picture.

As a key component in the LED display system, the performance and quality of the receiving card directly affect the display effect and stability of the entire screen. A good receiving card can process image data quickly and accurately to ensure the smoothness and clarity of the picture. At the same time, it also needs to have high stability and durability to cope with long-term high-intensity work.

In the application of LED display screens, receiving cards play a vital role. Whether it is commercial advertising, sports events or public information release, LED display screens cannot do without the support of receiving cards. It allows LED display screens to present more vivid and realistic picture effects, bringing more shocking visual experience to the audience.

In short, the receiving card is an indispensable "signal engineer" in the LED display screen system. Its existence provides a strong guarantee for the high-definition and high-refresh rate display effects of LED display screens. With the continuous advancement and innovation of technology, it is believed that receiving cards will play a more important role in the future and inject new impetus into the development of the LED display screen industry.
