What's LVDS
LVDS (Low Voltage Differential Signaling): It is a low-voltage differential signaling technology interface. It is a digital video signal transmission method developed by NS Corporation (National Semiconductor Corporation) in the United States to overcome the shortcomings of high power consumption and EMI electromagnetic interference when transmitting broadband and high bit rate data in TTL level.
In recent years, with the rapid development of the electronics industry, intelligent display equipment has also made brilliant achievements, and high-definition display has been favored by consumers. At present, the high-definition display protocol interfaces include RGB, LVDS, MIPI, eDP, HDMI, miniLVDS, V-by-One, etc
