PURPOSE: A multi-plasma display device is provided to reduce the brightness variation on an image by setting different sustain numbers of a sustain signal applied to one or more of plasma display panels. CONSTITUTION: A plurality of driving units(310,320,330,340) drive a plurality of plasma display panels(210,220,230,240), respectively. The plasma display panels are located in contact with each other and display an image by dividing the image using a plurality of subfields including a reset period, an address period, and a sustain period. The driving units output brightness values(APL1~APL4) on the divided images, share and compare the brightness values, and apply a driving signal based on a different brightness value to one or more of the plasma display panels. |
