customer can use a jumper cap to short - circuit the voltage pin according to the LVDS screen's voltage
parameters. (Please do not short - circuit two or more different voltages pins at the same time).
2.3.2 eDP (Optional)
When it is set as eDP functions, the “EDP/LVDS” pin transmits the eDP signal, the “L - BKL” is for the
backlight adjustment jumper and the “L_VCC/BKL” is for the display working voltage adjustment jumper.
