You can find a datasheet for the Sanyo display here: http://balva.chez-alice.fr/LCM552024NAK.pdf

Looks like a normal 4-bit input controllerless LCD. You could drive that with S1D13700 controller for example.

You did notice that this forum section is called "Crystalfontz Products - Technical Support", "Having problems with your Crystalfontz hardware? Ask about it in here." ? This thread might fit better under the "Other topics" section to be more on topic...

I don't know closer specifications of the NEC LCD.

But if you search for "LM688xw lcd" the results include this page:
Again gives a link to here:
Telling the LCD is used in a NEC MultiSpeed notebook.
Search for NEC multispeed gives some hints that it has a CGA display. Then finding some information about CGA tells that CGA maximum resolution is 640x200. So the resolution might be 640x200.
This is what couple minutes with a search engine reveals and this is where I'll stop and let you hunt for any further information :)

For the Sanyo display try searching for "USB S1D13700". ;)
