Hello everyone.
This is my first post on this forum. I have some knowledge in electronics, but not that much practice. It is only a hobby for me. Some notions I have may well be completely wrong too...
I've had some success playing with various audio amplifiyers, but that involved a lot of trial and error, and some nasty fails :-D
My first question concerns the power supply needed to drive an LVDS controller board.
I have bought such a thing for a small LED-backlit panel, mainly because I hate to throw things away
. I plan to make it a secondary display for my sons PC (usefull for music softwares). I will refer to it as my "new display"
I have done exactly that in the past, with success (I use it often). I will refer to this previous construction as my "old display"
Now, the new board I have ordered is supposed to be powerd by a 12v DC supply, rated "3A at least".
But when I measure the power consumption of my existing "old display" at the socket, it draws less than 11W, for a similar sized panel, LED-lit as well.
If I am not mistaken, 11 W represent a current flow of slightly less than 1 A at 12V. So 3A seems like an overkill
So I wonder if I could not get away with a smaller supply. Ideally, I would love to use some sort of integrated supply, and not an external "brick".
Shouldn't 2A be plenty ? Especially since the panel is a tad smaller and quite recent ?
Or is there something I am missing ?
