| 摘要 |
An apparatus to detect faulty connection of LED (open/short conditions) which may affect the function of LED display panel is presented. The apparatus basically controls the switches through control algorithm circuit to get the information of LED driver output pins voltage and compare them with two reference voltages to determine the open/short condition of individual LED. |
