JP6 - LCDPWR Polarity

LCDPWR output from S1D13705 is only active high but some panels may require an active low signal. To provide both active high and active low signals, the output from S1D13705 is inverted and the selection is made by the setting of JP6

When the jumper is in position 1-2, LCDPWR signal to the panel is active low When the jumper is in position 2-3, LCDPWR signal to the panel is active high
