Issue description

The formula for the brightness of the RGB lights depend on the brightness of the screen.

APPLIED_BRIGHTNESS=$(( ${LED_BRIGHTNESS}*${SCREEN_BRIGHTNESS_PERCENT}/100 ))

However, on trimui TSP, the LCD screen brightness can still be readable at very low brightness %. Typically, at night, I usually only use the very first increments. Also the RGB stick leds seem to accept only a few possible increments.
As a consequence, the LED sticks are switched off when screen brightness is below 10%.
