Nobody seems to sell small high-resolution LCD screens (by which I
mean, say, 15" and 1600x1200) commercially without a laptop wrapped
round them.

www.screentekinc.com will sell me panels, intended as replacement
parts for laptops that have been dropped and had the screen broken,
for $350; the panel has two connectors going to it, for the inverter
and for the video signal, and I get the impression that both these
connectors carry some fairly standard protocol.

Has anyone got a reference as to what the protocol is - I can't find a
data-sheet for a panel anywhere. Ideal part number would be an
LP154WU1, but if I try googling on that part number I get infinite
numbers of companies that sell replacement panels, and no datasheet.

Searched the words lcd pinout.

I always figued the connectors were too small for most to solder, so the
demand wasn't there... cool though.

Interesting question.

Sorry, some of the links on that page don't work, but the LG one does.

Thanks for the data. I don't think this is a feasible project, if
only because I don't know where to start building a 500V 6mA 35kHz
power supply, but I'm glad that the data's out there. It looks as if
mostly they use a 'standard' 41-pin connector with eighteen bits of
data, two +5 lines, fifteen grounds, and four clocks. Generating the
clocks sounds not impossible with an FPGA, though signal integrity
will be a nightmare with FPGA development boards the shape they are.

Just buy an iverter board.

Why would you want to build the inverter? You can pick them up for $5 or
so ready made.
