The diffusion panels can be accessed by lifting the
inner casing, typically held in place with clips which
can be removed with appropriate tools.
The panel consists of several plastic sheets which can
be processed.
A final consideration is that of the back light which
must be removed prior to processing. These may be
present along either the bottom, or either side of the
display as a strip of lights.
Lighting may be arranged across the entire back board
of the display.
Displays of this kind will have either Light Emitting
Diodes (LEDs) or Cold Cathode Fluorescent Lights
(CCFL).
Plastic parts can contain brominated flame retardants
