Change the brightness of the GC9d01 in the program?

Hello,
I've uploaded your program for the GC9d01 to an ESP32.
I can see the eyes on the round display, but only very faintly. How can I change this in your program?

Whether the routine picture is blurred or the picture you replace is blurred, ensure that the picture pixels and resolution match the screen.

Thanks for the info.
Can you give me the correct values for the GC9D01 display and where I need to change them in User_setup.h?
I'm a beginner here.
