I found another black splodged LCD, placed inside 2x sheets of silicone
rubber inside 2 slabs of cleaned thick perspex sheet in the vice and
left over night. Splodge in one area broke into a pretty dotty fractal
pattern over the whole display, then over minutes a fractally natural
fern-like spots . Have not so far managed to activate any segments,
assuming backplane is an end contact. I suspect the black will coaelesce
back into a solid area over the next few hours
