This display, SHARP LM64P51 has been used for the PowerBook 140 and some 145. You can replace it by the same or by the second model for 145/145B (SHARP LM64P58), but it is paired with the inverter board (find the pair, display + inverter). The CCFL backlight lamp is easy to replace.
There is a third model that goes in these PowerBook (140/145/145B): HITACHI LMG5200XTFC (to find with the cables and the inverter)...
I agree with bibilit, he problem with them is about capacitors failure. I had several down (bad picture or no picture, just the backlight that displays a blue halo).
After changing the capacitors (on the inverter board too), they work very well.
Done by bibilit, thanks to him ;-)
Before and after capacitors replacement :
The two SHARP display are very similar, like your picture, but the ref is different.
