I know. So what?

User wants to set brightness. Why should userspace know/care if it is
TFT or AMOLED?

I have this script:

#!/bin/bash
echo $1 > /sys/class/backlight/*/brightness 

why should I have to rewrite it just because you decided amoled is
special?

Kernel is expected to provide hw abstraction...
