Yes that's correct. Most of the led driver ICs can be controlled with a PWM signal to adjust or reduce the current(brightness). The driver ic used on the GearBest Screen i think is a CL6201. Look at the EN pin on the datasheet which says "The film is enabled. The EN pin can also be used for PWM dim...

Most of these screens have a led driver ic that can be dimmed via PWM. So I could basically wire the controller pin of that ic to raspberry's gpio and write program that would control brightness with that? I tried to search but didn't really find any documents about how to do that in practice. Do y...

I've been googling for hours but didn't really find an answer. I'm building my first Gameboy zero and I'm using the new gearbest display (last one on that page). My goal is to control at least the brightness of that screen. The screen doesn't have button board for controlling screen settings, but it...
