No screws. Too risky.
Is the 2x4 w/LEDs attached semi-permanently to the wall, or will it be hung using a French Cleat system?
If the latter is the case, use Power Grab Extra Strength, evenly applied so that when both assemblies are compressed together, so that when examined the two pieces seem to have no space between them. (...that would happen by using about a 3/4" wide bead...spread flat before assembly) If the two areas are completely wood on wood, then you can also safely use Wood Glue, but being careful to keep the Glue toward the outside edge of the 2x4.
Don't scrimp...but don't overdo. Put down clean plastic to set the screen face down on, mark the perimeter of the 1x frame where you want to set the outside edge of the 2x frame within, apply the adhesive of choice to the 1x stick Frame, keeping it at least 1" away from you marked outline...then put it down, press, and then get the 'ell way! Let it dry overnight before you consider moving it even an inch.
The one thing you have to avoid at all cost, especially if you opt to use a more fluid-like Glue such as Wood Clue, is to not have any squeeze out from under the outside edge of the 2x4 and manage to run down onto the spandex.
Now if the 2x4 Frame is affixed to the wall, then you will have to do it a different way. No need to go over than until needed.
