Method and device for determining LVDS (Low Voltage Differential Signaling) error channel without signal at receiving end, terminal and medium

The invention provides an LVDS (Low Voltage Differential Signaling) error channel determination method and device without a signal at a receiving end, a terminal and a medium, and the method comprises the steps: obtaining a first low voltage differential signal simulation oscillogram in a low voltage differential signal circuit interface test process based on a differential input mode; searching all channels corresponding to the first receiving end without receiving signals and aggregating to form a first channel set; acquiring a second low-voltage differential signal simulation oscillogram in a low-voltage differential signal circuit interface test process based on a single-ended input mode, finding out a second receiving end which is mapped with the first receiving end from the second low-voltage differential signal simulation oscillogram, and aggregating all error channels corresponding to the second receiving end to form a second channel set; comparing the channels in the first channel set with the channe
