I think it's a mis-translation of the term "repair buffer", which is as the name suggests used to compensate for defects in connectivity. There's a good explanation of that near the end of the LM6588 datasheet.
Another panel schematic I've found (attached) has the "rescue1" and "rescue2" designations, and indicates that sometimes these buffers are built into the source drivers themselves.
That's very interesting, thanks for the LM6588 link. Certainly what this IC is for. It's amusing that this is a quite nice quad op amp, that is present but probably not used on most of these model LCDs manufactured.
In that data sheet they say nothing about _how_ the repair lines get connected to any floating sections of column lines. Seems like something that would have to be done on the glass itself, since there are no flex-pcb attachments along the bottom edge. I'm assuming 'column' means vertical, in the normal screen orientation.
On the other LCD TV I trashed (a Samsung 46") there are no ICs on the main interface PCBs along the top edge. Only the driver chips bonded to the flex-PCBs. So if there's any 'rescue' column repair buffer facility on that, it must be in the final driver chips.
I find it amazing how they get the ulta-fine traces on those flex-PCBs all attached to the pads on the driver ICs.
Incidentally, on the 46" Samsung the front polarizing film peeled off quite easily, with no glue residue. It's fragile and tears easily, but the result was two nice big sheets of high quality polarizer.
Also the multiple sheets of diffuser film of various types behind the LCD are neat too, if you're doing anything optical that needs diffusers. And those big LCD TVs contain SO MANY long, thin CCFL tubes.
Oh, and actual schematics!
I don't suppose you (or anyone?) have the schematics for the Samsung 46" Model: LA46A650A1FXXY ?
Specifically:
- Main power supply board. Hansol model SIP468A Rev 1.3
- CCFL power sharing board . Samsung SSB460W22V01 LEFT Rev 0.1.
The first because the HV output for the CCFLs could be useful, and I'm interested how the drive regulation works. In the pic below the board looks simple, but the back is fairly packed with SMD.
The second because I really want to know what is going on on this board.
I found the Samsung service manual; no schematics. Nor by a quick google.
