Connect the output terminals V+ and V- in parallel, and then connect them to the display module. Connect the current sharing control lines EC between the power supplies in parallel. There is also a PG fault detection line. The normal voltage of this line is 3.3V, and it will be at a low level in case of a fault. VO is the output voltage detection line, which is equal to the V+ voltage. If the VO detection and PG functions are not required, the ports should be left unconnected.
