In LED display screens, HDMI cable (High-Definition Multimedia Interface) is a digital audio and video transmission cable used to connect video source devices (such as computers, Blu-ray players, game consoles, etc.) with display devices such as LED display screens. HDMI cable can transmit uncompressed high-definition video and multi-channel audio data with high quality, providing LED display screens with clear, delicate and synchronized audio and video experience.

The following are several key features of HDMI cable in LED display screens:

1. High-definition transmission: HDMI cable supports uncompressed high-definition video and audio signals with resolutions from 1080p to 4K, and even 8K in the future, ensuring that LED display screens can present delicate pictures and realistic sound effects.

2. High bandwidth: With the upgrade of HDMI interface version, its bandwidth continues to increase. For example, the data transmission speed of HDMI 2.1 version can reach 48Gbit/s, which can support video transmission with higher resolution and refresh rate, meeting the requirements of LED display screens for high-definition and high-speed transmission.

3. Single-line transmission: HDMI cable transmits video and audio signals simultaneously through one cable, which simplifies the connection process, reduces the clutter of cables, and makes the installation and maintenance of LED display screens more convenient.

4. Wide compatibility: HDMI interface is adopted by almost all modern TVs, projectors, game consoles, LED display screens and other devices, so HDMI cable has strong compatibility, which is convenient for users to connect various devices.

5. Plug and play: HDMI interface supports hot plug function, users can connect or disconnect HDMI cable while the device is running, without restarting the computer or display device, which improves the convenience of use.

6. Synchronous audio and video transmission: HDMI cable can transmit audio and image signals at the same time, realize the synchronous transmission of audio and video signals, avoid the tediousness of traditional interfaces requiring multiple cables to connect, and improve user experience.

In summary, HDMI cable plays an important role in LED display screens. It provides users with high-quality and convenient audio and video connection solutions with its high-definition transmission, high bandwidth, single-line transmission, wide compatibility, plug and play, and synchronous audio and video transmission.
