LVDS stands for Low Voltage Differential Signaling. It is a method used to transmit high-speed data over twisted pair cables with very low voltage swings. This technology allows signals to travel quickly while minimizing power consumption and electromagnetic interference (EMI), which makes it ideal for sensitive electronic environments.
When working on any LCD project, I’ve learned that one of the most overlooked yet critical components is the display cable assembly. It’s not just a wire. It’s the lifeline that connects your screen to the rest of the system, carrying high-speed signals and power with precision.
Coaxial cables may look simple from the outside, but they carry complex signals and must meet precise requirements. Whether you are designing for automotive, medical, communication, or industrial systems, understanding the key factors behind coaxial cable selection is critical to achieving long-term performance and system stability.
Coaxial cables are produced in many “RG” families that differ in impedance, diameter, dielectric, and shielding, which affects loss, bandwidth, and flexibility. For low‑loss RF and broadband distribution in homes and businesses, 75‑ohm RG‑series cables such as RG6, RG59, and RG11 are especially common.
Coaxial cable is designed with a built-in shield that protects against electromagnetic interference. This makes it ideal for environments with heavy electrical noise, such as manufacturing floors, military installations, or hospitals.
Two of the most commonly used coaxial cables are RG6 and RG59. Both are widely used in residential and commercial settings, including satellite television, security systems, and video transmission.
It has a unique layered structure. Inside, there is a copper core that carries the signal. Surrounding that is an insulating layer, a metal shield that blocks interference, and an outer plastic jacket that protects everything. This design helps prevent signal loss and ensures consistent performance, especially over longer distances.
I have seen firsthand how using the wrong cable can cause signal loss, electromagnetic interference, and even complete system failure. In many cases, it leads to unnecessary costs, delays, and serious frustration when the cable cannot handle the environment or fails to match the signal requirements.
When selecting coaxial cables for your internet, TV, or CCTV setup, one key decision is whether to use standard off-the-shelf cables or custom-made solutions. From my experience, standard cables are sufficient for most home or small-office applications where the runs are short and the environmental conditions are typical.
Coaxial cables work by allowing electrical signals (usually radio frequency or digital signals) to travel along the center conductor, while the surrounding metal shield blocks external electromagnetic interference (EMI).
