Searching your part number reveals that JINBANG8201 hardware also uses this same number on its FPC; however, having the same piece connecting the display to the main board does not necessarily mean the display has the same controller. You're welcome to try that firmware though.
The part number should be on the frame or the back of the LCM, like this GXBL177:
