ABSTRACT:
An image display device includes a display panel having gate and data lines electrically connected with pixels, gate and data drivers providing a gate signal and a data voltage, respectively, to corresponding ones of the pixels, and an inverter providing a lamp driving signal to drive a lamp unit. The lamp driving signal includes a wave signal of which rising and falling slope intervals are substantially equal to each other during a gate-on voltage interval in which the data voltage is charged in corresponding one of the pixels. The image display device also includes a signal controller for generating a gate control signal to control timing of generation of the gate-on voltage and a synchronization signal having a 90° phase difference with respect to the gate control signal. The synchronization signal is provided to the inverter.
