Abstract:
1. An inverter apparatus configured to individually supply an operation voltage to first and second lamp groups included in a display device, the inverter apparatus comprising: a first inverter circuit configured to receive a driving voltage signal from the outside and first and second scanning control signals for controlling the first and second lamp groups to turn on and off, and to output a first operation voltage signal for a first operation frequency associated with the first scanning control signal, the first inverter including: a second inverter circuit configured to receive the driving voltage signal and the first and second scanning control signals, and to output a second operation voltage signal for a second operation frequency associated with the second scanning control signal, wherein the first operation frequency for the first lamp group is decreased to a predetermined value in response to the change in the resonance frequency when the first and second lamp groups are set to be in an on-state simultaneously in response to the first and second scanning control signals.
