Probably a Hitachi LCD interface. Search around for Hitachi HD44780.

I would not be surprised if those 7 wires are 3 power (blk gry wht) and 4 USB. Maybe it’s actually 2 serial data lines, control and text? Maybe try to trace out the PCB and get any identifying marks from the ICs? If one is a microcontroller or ram or rom or a USB controller that would go a long way in getting it reverse engineered. For real though, they probably are using standards like i2c or USB or rs232, no sense reinventing what works

If you can identify the LCD itself, alibaba may have replacement driver boards for cheap

I googled the name listed on the PCB and found This. Seems doable, the spec sheet goes into a lot of detail on how the serial interface works

Sorry for the late reply, sync doesn’t seem to be handling reply notifications very well at the moment. In theory, you could power this display through something like an Arduino. For something like this, you’ll want to use the driver board to control the display. The data sheet goes into a lot of detail about how the display works using the serial input and explains a good bit how the signal would be interpreted. The hard part is going to be handling the translation between what you want displayed and what the display needs to receive to show it. That’s where your homeworks going to be. I’m more of an old school hobbyist who never graduated to microcontrollers. The Arduino is going to handle the translation for you, but I don’t know enough arduino-fu to be helpful there. I’d recommend looking into using an Arduino with similar displays to see how other people do it, and then ruthlessly cannibalizing their code to fit with your needs.
If you have any other questions along the way, feel free to send a message my way. I can’t guarantee I’ll have the answer, but I’m happy to lend my experience where applicable. Best of luck to you bud!
