The board acts as the structural "heart" of the display. It converts high-voltage Alternating Current (AC) mains power into precise, low-voltage Direct Current (DC) rails. These rails drive the logic processes on the main video scaler board (often paired with the ILIF-473 or ILIF-460 video driver board ) while simultaneously lighting up the LCD panel backlights.

The primary function of the ILPI-354 V.A board is two-fold: converting standard AC mains voltage (90V–264V) into stable DC voltage rails, and providing high-voltage constant current to illuminate the display's LED backlighting.
