How does an LCD inverter work?
In simple terms, an LCD inverter takes the direct current (DC) power from the device’s battery or power supply and converts it into the alternating current (AC) power needed to light up the screen’s backlight. This backlight is what allows you to see the images on the LCD panel. There are two main types of LCD backlights that use inverters:
