performance. The processor core control is maintained by an embedded controller.

The graphics driver dynamically adjusts between P-States to maintain optimal

performance, power, and thermals. The graphics driver will always try to place the

graphics engine in the most energy efficient P-state.

The Intel DPST technique achieves backlight power savings while maintaining a good

visual experience. This is accomplished by adaptively enhancing the displayed image

while decreasing the backlight brightness simultaneously. The goal of this technique is

to provide equivalent end-user-perceived image quality at a decreased backlight

power level.
1. The original (input) image produced by the operating system or application is

analyzed by the Intel DPST subsystem. An interrupt to Intel DPST software is

generated whenever a meaningful change in the image attributes is detected. (A

meaningful change is when the Intel DPST software algorithm determines that

enough brightness, contrast, or color change has occurred to the displaying

images that the image enhancement and backlight control needs to be altered.)

2. Intel DPST subsystem applies an image-specific enhancement to increase image

contrast, brightness, and other attributes.

3. A corresponding decrease to the backlight brightness is applied simultaneously to

produce an image with similar user-perceived quality (such as brightness) as the

original image.

Intel DPST 6.0 has improved the software algorithms and has minor hardware

changes to better handle backlight phase-in and ensures the documented and

validated method to interrupt hardware phase-in.

The 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. The converse applies for a brightly lit environment. Intel

Automatic Display Brightness increases the backlight setting.

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 plugged in with an AC power adaptor 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 DRRS method

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