The transmission cable in the display is an important component that connects the display to other devices (such as the host, image processor, or power supply) and is responsible for transmitting signals and power from external devices to the display. Transmission cables are usually composed of multiple wires, each of which performs a different function, such as transmitting video signals, audio signals, control signals, or power supplies.

For liquid crystal display (LCD), LED display or OLED display, the transmission cable needs to support high-speed data transmission to ensure that the image signal can be quickly and accurately transmitted to the display panel. Common transmission cables include HDMI, DisplayPort, VGA, and DVI, which are used to transmit video signals, while power cables provide the required voltage and current for the display.

In modern displays, the quality of the transmission cable is crucial to the display effect. High-quality cables reduce signal interference, avoid image distortion, and ensure stable signal transmission. In addition, with the development of display technology, the design of transmission cables is also constantly optimized, such as cables that support higher resolution and higher refresh rate to meet the needs of high-definition displays such as 4K and 8K.
