Video Subsystem
The primary display is a 12.1-inch color TFT LCD. The video interface
is 24-bit Flat Panel Display Link (FPD-Link) using LVDS.
The display has an LED backlight supplied with 12-volt power. A
PWM control signal controls the brightness of the LED backlight.
The power supply microcontroller generates the PWM control signal
under the direction of the host application.
The secondary display is an external monitor compatible with
standard Digital Visual Interface (DVI) signaling. The interface is
DVI-D which supports digital-only, single-link.
The secondary display has the same image and resolution as the
