Abstract
Two extended embedded Display Port displays may be enabled by using a single set of panel power sequencing (PPS) signals from a chipset to enable the two embedded Display Port panels. To enhance the user experience, the backlight module brightness is controlled by making use of a pin available on a system on a chip (SOC) and modification of drivers. This helps to save power when only one panel is used. When both panels are used simultaneously, power savings can be achieved by using backlight control signals.
