Abstract： Based on the Micro-LED product series, this experimental project has designed an FPGA-based LVDS automatic calibration for the multi-channel video stream transmission system. The system platform is equipped with an external GSV2011 decoding chip, which converts the obtained 2K@120 Hz/4K@60 Hz video stream signals into 80-bit data package according to custom specifications, and then pushes them to the LYDNT27001 constant current source display driver chip. In thise system, the video stream data transmission involves multiple levels of FPGA chip data transfer, utilizing LVDS low-voltage differential transmission technology. In order to adjust the data bit alignment and sampling stability issues with the SerDes, the reference and monitor signals are identified during the process of data stream transmission video stream data of this system transmits through LVDS multiple channels, which can achieve a transmission rate of up to 10 Gb/s. This experimental project demonstrates that the system can operate stably, reliably, and efficiently, therefore it has certain practical value in engineering field.
