LVDS line is a line used to transmit low-voltage differential signals; the full English name of LVDS is "Low-Voltage Differential Signaling", which refers to low-voltage differential signals. It is a kind of low-power consumption, low bit error rate, low Crosstalk and low-radiation differential signaling technology; the core of LVDS technology is the use of extremely low voltage swing high-speed differential transmission of data, which can realize point-to-point or point-to-multipoint connections. The transmission medium can be copper PCB wiring. Can also be a balanced cable.

What does the lvds line mean?
LVDS line is a line used to transmit low voltage differential signals (LOW VOLTAGE DIFFERENGIAL SIGNAL).
LVDS (Low-Voltage Differential Signaling) is a differential signaling technology with low power consumption, low bit error rate, low crosstalk and low radiation. This transmission technology can reach more than 155Mbps. The core of LVDS technology is the use of extremely low voltage swing high-speed differential transmission of data, which can realize point-to-point or point-to-multipoint connections. The transmission medium can be copper PCB wiring or balanced cables.
LVDS (Low Voltage Differential Signaling) is a low amplitude differential signaling technology. It uses very low amplitude signals (around 350mV) to transmit data over a pair of differential PCB traces or balanced cables. It can transmit serial data at speeds up to thousands of Mbps. Since the voltage signal amplitude is low and driven in constant current source mode, it only generates very low noise and consumes very little power, and the power consumption is almost unchanged regardless of the frequency. In addition, because LVDS transmits data differentially, it is not susceptible to common-mode noise.
LVDS was first proposed by National Semiconductor as a high-speed signal transmission level. Since then, LVDS has been defined in the following two standards: IEEEP1996.3 (adopted in March 1996 ), mainly for SCI (Scalable Coherent Interface). It defines the electrical characteristics of LVDS and also defines the encoding during packet exchange in the SCI protocol; ANS/EIA/EIA-644 (passed in November 1995), mainly defines the LVDS electrical characteristics, and suggested parameters such as the maximum transmission rate and theoretical limit rate. The LVDS standard usually mentioned refers to the latter. The 2001 ANS/EIA/EIA-644 standard has been revised and published.
