The LCD panel connectors I ordered from Digikey arrived today... and they're tiny!
Actually, I ordered what I thought were the right parts, but they're not what I actually need, I think.
I was close, though.. I was off by 20 pins on one, and the wrong wire type on the other.
Hi-resolution scanned pic attached.
The connector on the left is a Hirose DF13-20DS-1.25, and is a dual-row socket connector with 20 pins.. I meant to order one with 40 pins, and with crimp connectors instead of pins. The pins are spaced 1.25mm apart, to give you some idea of scale.
The 40-pin version of the connector on the left is the kind that fits the LVDS connector on most motherboards.
The connector on the right is a Hirose DF19G-20S-1SD, and is a 20-pin connector used on the LCD panel that I chose. The pins are spaced 1mm apart, and the actual contacts are on the left side of the connector, not the right. The wires can be soldered to the pads on the right side, and the entire thing is about 20mm wide.
The toothy part on the right side is one half of a shield - the other half snaps on top of the connector.
I think I ordered the wrong style connector on the right, because this version is made for super-thin AWG 40 coaxial cable such as this:
There is another style of this connector that can use thicker AWG 28 cable that might be easier to solder to the connector..
The good thing is, the connectors aren't that expensive - I bought each of those two for about $2.50 each.
Edit: Attached a Word doc with the pinout mappings I need.
