The control system of LED Display is the core part to ensure that the display screen can accurately and stably display images, videos and text information. Its working principle is complex and sophisticated, mainly involving multiple links such as signal reception, processing, transmission and final display control.
1. Signal reception and processing
The control system of LED Display first receives image and video signals from computers, media players or other signal sources. These signals usually contain rich color, brightness and grayscale information, which need to be encoded and compressed by the processor in the control system. The processor converts these original signals into a data format suitable for the display of LED Display to ensure the accuracy and integrity of the information.
2. Data transmission
The processed image and video data are transmitted to the control system of LED Display through data lines or networks. In this process, the data may pass through intermediate devices such as sending cards and receiving cards, which are responsible for segmenting, reorganizing and distributing the data to ensure that the data can be efficiently and accurately transmitted to each pixel of the display screen.
3. Display control
At the receiving end of LED Display, the control system decodes and reconstructs the received data to restore the original image and video signals. Then, the control system uses grayscale control technology and correction algorithms to accurately adjust the brightness and color of each LED pixel. Through real-time monitoring and feedback from optical sensors, the control system can ensure the brightness and color consistency of the display, thereby presenting a high-quality display effect.
4. System integration and collaborative work
The control system of LED Display is a highly integrated system consisting of multiple key components, including control cards, sending cards, receiving cards, and control software. These components work together to realize the control and management of LED Display. As the core of the system, the control software is responsible for configuring and managing the display content to ensure that the display can work according to the preset requirements.
In summary, the control system of LED Display realizes precise control and management of the display through multiple links such as signal reception and processing, data transmission, display control, and system integration and collaborative work, providing users with excellent image and video display effects.
