Abstract: Liquid crystal display device 1 includes pixels PX, individual and common electrodes PE and CE provided for pixels PX and flicker compensation circuit 8. Flicker compensation circuit 8 changes a central level of common voltage Vcom for common electrode CE. Flicker compensation circuit 8 is provided with capacitor 31, variable resistor 32, switch 34, arithmetic operation circuit 33 and buffer amplifier 35. Capacitor 31 supplies common voltages Vcom from common voltage generation circuit 6. Variable resistor 32 changes common voltages Vcom while switch 34 selects one of two different voltages VCC1 and VCC2. Arithmetic operation circuit 33 combines an output of variable resistor 32 with that of switch 34 and buffer amplifier 35 supplies thus combined outputs V'com to common electrode CE as compensated common voltages.

Abstract: A flat-panel display device changes the level of a video signal supplied from a video signal source in the horizontal blanking period on the basis of a selected voltage value from a voltage generation circuit, and this voltage is sampled in response to a sampling clock from a timing generation circuit and is latched by a signal line driving circuit. The latched signal is supplied to a flat display panel along with a scanning signal from a scanning line driving circuit to display an image according to the aspect ratio of the flat display panel.
