Can I control the backlight brightness?
CCFL frame rate can be modulated for a smaller percentage of time at full voltage.
This may cause some noise but you can have limited control of the CCFL. However LED backlight brightness is easier to control. It can be achieved by regulating the backlight DC- current, PWM control, or implementing special LED drivers (IC).
