Seem to be. perhaps they were made for different markets?  They seem to use the same drivers.

from the sensor to the drawing plate of the case (of a UD 1212) is about 6mm, then add whatever happened with your paper test.

Thickness of the LCD itself will be about 2mm. other dimensions will vary I guess.  Thickness of the slab in the backlight will probably be between 5mm - 8 mm on a Samsung screen.

I'm not sure I understand what you mean.    If I were doing it I would get LEDs of the same diameter as the panel thickness and replace the flourescent tubes down the edges.  I think a full-on array across the whole screen would be a lot more work for little or no benefit.
