12V LVDS Backlight
An on board voltage regulator is used to provide 12V for the backlight voltage. The voltage
regulator delivers 12V (1A max) when 15V < VCCIN < 28V. (See also 3.22.8 12V SATA and
Fan Voltage)
When the input is 12V, this input voltage can be directly coupled to the 12V LVDS Backlight
and LCD panel power. A jumper J1301 is provided to enable this.
