LCD Power Inverter

Without light, and LCD screen might as well be a paperweight. Many LCD screens use a cold-cathode fluorescent lamp that requires an inverter. Commonly known as a CCFL inverter, this component prepares the power connection of the DC power supply to work with the AC power requirements of the lamp.


The Inverter’s Role

When a computer is plugged into the wall, it converts the power outlet’s AC waves into DC. This works well for digital components, such as the motherboard, but it doesn’t work for fluorescent bulbs. The inverter intercepts that DC power, and converts it back to AC power for use by the bulb that lights the screen.
