The insides are quite similar on these screens. They are all less than 1/2" thick. The smallest is #1 and #2 both at just slightly over 3/8"
#1 is the hardest to take apart and use. You have 8 screws to remove. You have to pry the Lcd plastic case apart. You have to remove the ffc extension. The lcd and the ffc extension are double sided taped on and difficult to pry off. And you have to re-attach the lcd ffc when done which is slightly difficult and the ffc connector can break.
#2 is the easiest and simplest to take apart and use. 2 screws and everything falls right out. And the controller board is already taped to the Lcd .
#3 is easy to remove with 4 screws but the Lcd is double sided foam taped to the controller board and these need to be removed to make the lcd/board thinner.

Now for current draw.
#1 -- 113mA
#2 -- 125mA
#3 -- 128mA
I really like the brightness of #2 and the fact that it has "warmer" colors. But the top angle wash-out and the side darkening is hard to ignore. Also the screen is the glossiest of all of them with a lot of glare.
I like the antiglare on #1. For a portable that helps to eliminate a lot of the glar and mirror like problems of reflection. But the brightness is a bit lower than the rest. The more natural reds and browns and the better contrast are almost worth the decrease in brightness though.
#3 is overall very good. Not the brightest , not the best colors, but overall good in every detail.
Which one will I use. Well it's hard to say. I my Nomad mods I might go with #2 since it is behind another plastic screen on the Nomad which would reduce glare and it's nice and bright and it's VERY easy to disassemble and use.. For an exposed screen portable , probably #1 because of the antiglare.
Oh and with all of these. If using them in a portable, the negative (ground) power wire needs to be tied in to the negative (ground) wire on the yellow rca plug to work properly.
