pardon me if this is too vague for now
It is too vague for a little text box like this - this is "Quick answers" and you don't give anywhere near enough info to even begin answering it in any detail.
So start with the display unit itself: it needs to either be connected directly to the internet (with an IP address or programmable so it can "announce" it's availability to your IP address) or be connected to a device which is.
Then look at what it's manufacturer says about it: how does it suggest you display data?
Only then can you even start to work out how to actually program code to work with it!
