4 OpenLDI/Low Voltage Differential Signaling

OpenLDI/Low Voltage Differential Signaling (LVDS), a variation of LVDS, is a differential signaling technology primarily used for high-speed data transmission. Compared to DPI, LVDS minimizes the number of signal lines needed and supports long cable lengths, making LVDS a popular choice for large screen displays and industrial applications.

LVDS interfaces offer robustness against electrical noise, power efficiency, and high data rates. These features make LVDS designed for high-speed, high-resolution display systems. LVDS is commonly found in HDTVs, high-resolution monitors, laptops, and medical imaging devices.

However, compared to DSI, LVDS interfaces consume more power and require more physical connections, making them less designed for compact and power-constrained applications.
