Synchronous Control System

Components of LED Display Synchronous Control System:

1. Control Host: The control host is the main device that manages the operation of the LED display screens. It receives the input signals and sends them to the display screens in a synchronized manner. The control host is responsible for processing the data and ensuring the correct display sequence.

2. Sending Card: The sending card is a key component that connects the control host with the LED display screens. It receives the data from the control host and converts it into a format that can be understood by the display screens. The sending card also controls the brightness, color, and other parameters of the display screens.

3. Receiving Card: The receiving card is installed in each LED display screen and receives the data from the sending card. It decodes the data and controls the display of the LED pixels. The receiving card ensures that the images and videos are displayed correctly and synchronized with other screens.

4. LED Display Screens: The LED display screens are the output devices that show images and videos to the viewers. These screens consist of a grid of LED pixels that can emit different colors. The display screens are synchronized by the control host and display the content in a coordinated manner.

Product Performance

When considering the purchase of a rental LED display, it is crucial to understand three key factors: contrast ratio, refresh rate, and gray scale performance.

Contrast ratio refers to the difference in brightness between the brightest and darkest areas of an image displayed on the LED screen. A higher contrast ratio means that the display has a greater ability to reproduce deep blacks and bright whites, resulting in a more vibrant and visually appealing image. A contrast ratio of 4000:1 or higher is generally considered good for LED displays. This ensures that the content displayed on the screen is clear and easily visible, even in brightly lit environments.

Refresh rate is another important aspect to consider when evaluating the performance of a LED display. It refers to the number of times per second that the image on the screen is refreshed or updated. A higher refresh rate, typically measured in Hertz (Hz), provides smoother motion and reduces motion blur. A refresh rate of at least 60Hz is recommended for LED displays to ensure seamless video playback and smooth transitions between frames.

Gray scale performance is the ability of a LED display to accurately reproduce shades of gray. It is measured in bits and refers to the number of levels of gray that can be displayed. A higher gray scale performance allows for more precise and realistic image rendering. The commonly used gray scale performance for LED displays is 14-bit or higher, which can display over 16,000 levels of gray. This ensures that the display can accurately reproduce subtle color gradients and fine details.
