The driver element is a specialty device, likely designed for that
specific company. Can you read any labelling on the device?

No label. Because it's not a motherboard kind of thing, there is no
webpage listing its specification and parts list.

But, to avoid loading the planet down with even one more yoyo-sized
amount of ewaste, I suggest contacting the manufacturer and having it
repaired under warranty. If it is out of warranty, contact the
manufacturer and have a new driver element sent to you. If they are no
help, as you can apparently read Chinese you can use alibaba to find a
manufacturer of the driver element.

It's out of warranty. I salvaged it from a rich family.
