I wonder why they haven't solved the problem of flicker with front/backlights. If I recall correctly, the intensity of an LED is related to the current passing through it. A simple approach involves using a potentiometer, which I understand isn't popular because it isn't software controlled. (Again if I recall correctly,) transistors can use voltage to control current as well, so it should be easy to design a software controlled way to control the intensity of a backlight using transistors.

Is there something that I'm missing?
