Brightness of OLEDs

[FantomXR]

Hey out there,

I received another bunch of OLEDs from China and they are much darker than the others I had before. Is there any solution on the software-side for that issue? 
I don't know what I need to change on the hardware-side / on the OLEDs to make them brighter....

Thanks,
Chris

Alright. I found a way to boost the brightness of the OLEDs. 

It's in the app_lcd.c of the universal-driver folder in line 678

APP_LCD_Cmd(0x7f); // middle

change it to

APP_LCD_Cmd(0xff); // high

done!

But anyway: My new oleds are still much darker than the other ones....
