I just bought a PCB which shows up and down volume steps from remote control on two 1-digit LED displays driven by a JXI5020GF, but there is a project error: the number 1 digit on both ones is on the wrong side (please look at the pic in attachment).
Is there a way in order to solve that issue?
Any addressing is more than welcome!

Where did you get the board? What is the decoder driver chip? What does the
data sheet say? I don't remember ever seeing that issue. If it is the Holtek I²C
decoder driver the segments are set with a lookup table so it can be
anything you want.

JXI5020GF is not a BCD to 7 segment decoder but a 16 bits led drivers.
As suggested by Stratus, you can do what ever you want through your software via SPI interface.
Even if datasheet is in chinese, it remain understandable :

Sorry if I don't mean in any way 7-segment display, so I can't understand your appreciated replies: maybe the best way is to leave things just as they are otherwise you should give me a crash course on both led drivers or BCD to 7 segment decoders...
On the 2nd board there is only an IC that could be related with the 7-segment display, but it is probably a cheap customized IC with both the label erased, and errors...
Anyway thank you very much!

Please note that I meant to say: "Sorry if I don't know enough about 7-segment display, so I can't understand your appreciated replies"
Thanks
You’re right second chip is certainly an asic or cheap microcontroller and fixing the display error seems difficult...
You could try turning the display upside down but it will fine only for the number 11...😉

I had already thought of it, but please note that it wouldn't work even for the number 11 because its inclination would be wrong... 😀

No, that's impossible.
Rotate it 180 degrees to turn it upside down, mirror imaging a solid object is impossible 🙂

Yep, you're just right!
P. S.: However at least the dot would be in wrong sides... 😀
Anyway congratulations for your attention
