No I think it's LCD screen, this laptop is almost 10 years old
You might try the indie Brightness-Controller:

brightness-controlller
Is that a typo? controller? I typed sudo apt install brightness-controlller into the terminal and it can't find the package.

Do I need to reboot or it works automatically?
It is a GUI app - should appear in your app menu after installation is complete.

It works but it doesn't integrate with gnome's brightness and Zorin Os theme because the application is not dark theme control. Sad
I believe it is built with the QT toolkit.
If you want a brightness controller that integrates with Gnomes controls, a gnome-extension may be the way to go.
Hmm ok I will install gnome tweaks and maybe try some extension, yes it's a QT application I always don't like that two toolkits look weird, when I was using KDE I always cringed when I see a GTK application on KDE
I understand completely. I am the same way. You can use qt5ct to make QT apps use gtk themes on Zorin OS.
Ussually I just completely avoid QT apps because they look really off, I once saw my brother using dolphin on Gnome and I just can't

linux for hardware support has always had various glitches, my oled monitor in zorin can not adjust the brightness, but also need to use third-party methods to be able to, but pop os can perfectly support oled monitors, but pop os also has a disadvantage for the thunderbolt 3 support is not too good.
I heard that the kernel above 5.13 supports oled displays to adjust the brightness, I upgraded my kernel, but still can not adjust the brightness
My kernel is 5.13
I just switched kernels, I didn't rebuild them
You are a godsend! I will be mentioning this in my next post as its important!

Brightness controller can be installed, but fails to set maximum brightness.
screen is still not at full brightness, even though the brightness bar ist at 100%
