Title:
METHOD AND DEVICE FOR DETECTING ANOMALY IN DIFFERENTIAL SIGNAL RECEIVING TERMINAL OF LIQUID CRYSTAL DISPLAY MODULE
Document Type and Number:
WIPO Patent Application WO/2013/159421
Kind Code:
A1
Abstract:
Disclosed is a method for detecting an anomaly in a differential signal receiving terminal of a liquid crystal display module. The detection method comprises: sequentially inputting high levels to LVDS0+, LVDS0-, LVDS1+, and LVDS1-, and each time only inputting a high level to one differential signal line, the input of the rest differential signal lines being in a high-resistance state; and receiving feedback signals of all differential signal lines, and determining, according to the feedback signals, whether an anomaly has occurred on a differential signal of a detection unit, the anomaly comprising an open circuit of a terminal resistor of a differential signal line, a short circuit between two differential signal lines, and a short circuit to the ground or a short circuit to a power supply from the differential signal line caused by an abnormal power supplying sequence. In the present invention, by sequentially inputting high levels to differential signal lines and then receiving a feedback signal of each differential signal line, an anomaly on a receiving terminal can be rapidly detected according to the feedback signal, thereby saving the labor cost and time cost, and further increasing the efficiency of detecting an anomaly.
