Basic knowledge of the LVDS connector wiring harness The lvds interface standard:

The LVDS interface is the common interface standard of LCD Panel, taking 8-bit Panel as an example, including 5 sets of transmission lines, where 4 sets are data lines, representing Tx0 + / Tx0-… Tx3 + / Tx3-. There is also a clock signal, representing TxC + / TxC-. The corresponding one has 5 sets of receiving lines at the Panel end. If it is a 6-bit Panel, there are only 3 sets of data lines and one set of clock lines. The LVDS interface, also known as the RS-644 bus interface, is a data transmission and interface technology that only appeared in the 1990s. LVDS is a low voltage differential signal, the core of this technology is to use very low voltage swing high speed differential transmission data, can achieve point to point or point to point connection, with low power consumption, low code error rate, low crosstalk and low radiation characteristics, its transmission medium can be copper PCB connection, or balance cable. LVDS has been increasingly widely used in systems with high requirements for signal integrity, low jitter and co-modeling. Currently, the popular LVDS technical specification has two standards: the A N S A / TIA / EIA-644 standard of TIA / EIA (Telecommunications Industry Alliance / Electronics Industry Alliance), and the IEEE 1596.3 standard. In November 1995, the ANSI / TIA / EIA-644 standard was introduced, mainly led by American semiconductor companies. In March 1996, the IEEE published the IEEE 1596.3 standard. These two standards focus on the electrical characteristics of the LVDS interface, interconnection and line termination specifications, and the production process, transmission medium and power supply voltage are not clear. The LVDS can be implemented using CMOS, GaAs or other technologies, with a supply voltage from + 5V to + 3.3V or even lower; its transmission medium can be a PCB connection or a special cable. The standard recommended data transmission rate is 655Mbps, and in theory, in a decay-free transmission line, LVDS transmission rate up to 1.923Gbps.—-OpenLDI standard is widely used in laptops, most laptops LCD display and the host board between the connection interface adopts the OpenLDI standard. The basis of OpenLDI interface standard is Low Voltage Differential Signaling (LVDS) interface, which has the characteristics of rate, low power consumption, high speed, low cost, low clutter interference, can support high resolution and so on. The LVDS interface is widely used in telecommunications, communications, consumer electronics, automotive, medical instruments, and has been supported by AMP, 3M, Samsung, Sharp, Silicon Graphics, and others. In order to penetrate the desktop space, NS has introduced a new OpenLDI standard chipset DS90C387 and DS90 support, specifically for LCD displays
