@Mohit-Tripathi Please give us more information first.
How are you controling the one LED?
Can you show the code where you're doing this?
I'm pretty sure, this topic "referes" to this previous one: https://forum.qt.io/topic/88973/how-we-can-read-particular-string-data-from-any-device-to-print-on-particular-lcd-in-qt

Can I know how we can define particular pin on arduino by Qt code?
Given that you're already able to read the device and update one LCD in Qt, it looks like your issue turned into defining a protocol so when you read the serial port, you could decide what LCD to update and in that way the issue is not related to Qt anymore :-)
