What are the protocols used by LCD panels?

Question

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

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.-JB

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.

I don't know where to start building a 500V 6mA 35kHzJust buy an iverter board.

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