This is a mobile only supported power management feature.

Intel

®

 Automatic Display Brightness feature dynamically adjusts the backlight 

brightness based upon the current ambient light environment. This feature requires an 
additional sensor to be on the panel front. The sensor receives the changing ambient 
light conditions and sends the interrupts to the Intel Graphics driver. As per the change 
in Lux, (current ambient light illuminance), the new backlight setting can be adjusted 
through BLC (see section 11). The converse applies for a brightly lit environment. 
Intel

®

 Automatic Display Brightness increases the back light setting. 

This is a mobile only supported power management feature.

When a Local Flat Panel (LFP) supports multiple refresh rates, the Intel

®

 Display 

Refresh Rate Switching power conservation feature can be enabled. The higher refresh 
rate will be used when on plugged in power or when the end user has not 
selected/enabled this feature. The graphics software will automatically switch to a 
lower refresh rate for maximum battery life when the notebook is on battery power and 
when the user has selected/enabled this feature. 

There are two distinct implementations of Intel

®

 DRRS—static and seamless. The static 

Intel

®

 Display Refresh Rate Switching Technology (Intel

®

 DRRS Technology) method 

uses a mode change to assign the new refresh rate. The seamless Intel

®

 Seamless 

Display Refresh Rate Switching Technology (Intel

®

 SDRRS Technology) method is able 

to accomplish the refresh rate assignment without a mode change and therefore does 
not experience some of the visual artifacts associated with the mode change (SetMode) 
method.
