Abstract
An inverter for liquid crystal display is disclosed. The inverter for liquid crystal display includes a switching circuit, a transformer, and first and second protective circuits. The switching circuit includes first and second switches and converts a direct current power input into an alternating current power. Each of the first and second switches alternatively performs a turn-on operation and a turn-off operation. The transformer transforms an alternating current power supplied from the switching circuit into a high-voltage alternating current power. The first protective circuit is connected to both terminals of the first switch and protects the first switch during turn-on and turn-off operations of the first switch. The second protective circuit is connected to both terminals of the second switch and protects the second switch during turn-on and turn-off operations of the second switch.
