I got my hands on an old e-ink price tag and want to repurpose this display.
Unfortunately, I can’t really figure out, what this type of connector/bus is called. To me it looks like a standard issue ribbon cable.
There are some “universal” e-paper drivers (for example this one: https://www.ebay.de/itm/353141399922), but I have absolutely no idea, how to find out, if that’s the right connector.
The device is made by Imagotag, if that helps.
Edit: I added a picture of the panel: https://feddit.de/pictrs/image/42ee4f60-231a-4c42-9a66-6c369134c49c.jpeg
None of the “markings” returned any results and the QR code couldn’t be decoded by my phone.
Hey, I am not 100% sure but from other screens i have seen it is probably to boost power. One of the open source ereaders has a little chip that is similure. It is probably a spi display. Do you have the model number of the panel?
I don’t have model number and there are zero indications to who manufactured it. I added a picture of the backside. That’s everything readable on the panel. Nothing else.
The connector on the PCB is called a ZIF (zero insertion force) connector. Normally they are specified by the number of pins, the pitch of the pins, and whether there is any locking feature or “ear” on the sides of the ribbon cable. It looks like a standard latching connector made by any number of companies.
The ribbon cable looks like it is custom designed for the display’s electrical pin out and the mechanical design of the enclosure.
If you can figure out the mfg of the display itself, you should be able to figure out the ribbon cable pinout.
I know a fair bit about connectors and circuit fab, but not an EE so hopefully this helps!
I added a picture of the panel, but as written in the other comment: no manufacturer to see - at least to me.
At least pin-count-wise, the driver I linked above should fit, and all e-ink displays for hobby use do seem to be driven by SPI, but whether it’s the “same kind” of SPI and pinout…
