Backlight Brightness Control:
Provides a variable DC voltage between 0V and 4V via an RC lter (10kOhm / 20uF; buffered output). Alternatively, a 3.3V PWM signal
is available, see related jumper setting. Basically the LVDS brightness level can be selected by BIOS Setup, but it is also accessible from
Windows OS (Control Panel – Power Options – Screen Brightness). Access depends on appropriate setting in BIOS Setup. If this control signal
is used, the system integrator is responsible for the implementation of a backlight converter that ts to the control output voltage range.
Backlight On/Off Control: Active High, 3.3V
Note
Polarity can be changed via BIOS Setup.
