It's not a hard fast rule, but think what benefit your post is to others.
If you have a new item, but know very little about it and are unwilling to take it apart, then "Brag Gallery".
If you have questions or problems, and have photographed it, then in LED or LCD, whichever is appropriate.
You could post in both areas, but probably not necessary.
If you don't have a picture - nobody cares.

Just kidding...but it does make it easier for others to get interested.
