Abstract
A plasma display device to generate a stable reset discharge and to reduce background luminance and a method of driving the same. The plasma display device produces images by dividing the frames of displayed images into a plurality of sub-fields, which include a reset period, an address period, and a sustain period. The method includes: supplying a first main reset pulse in the reset period of ith frames (where, i is natural number); and supplying second and third main reset pulses in reset periods of (i+1)th frames, which are alternatively produced with the ith frames. The first main reset pulse having a different voltage than the second and third main reset pulses.

A method of driving a plasma display device driven by dividing one frame into a plurality of sub-fields each comprising a reset period, an address period, and a sustain period, the method comprising:
- supplying a first main reset pulse during one of the reset periods that is earliest in time in an ith frame (where i is a natural number);
- and
- supplying second and third main reset pulses during consecutive reset periods that are earliest in time in an (i+1)th frame that is alternately displayed with the ith frame,
- wherein the first main reset pulse has a different duration than the second and third main reset pulses.
A plasma display comprising:
- a plasma display panel;
- a controller configured to divide one frame into a plurality of sub-fields each comprising a reset period, an address period, and a sustain period, and to control alternatively driving an ith frame (where i is natural number) and an (i+1)th frame;
- and
- a driver configured to supply a first main reset pulse to the plasma display panel during one of the reset periods that is earliest in time in the ith frame and to supply second and third main reset pulses during consecutive reset periods that are earliest in time in the (i+1)th frame,
- wherein the first main reset pulse has a different duration than the second and third main reset pulses.
A method of consecutively driving ith and (i+1)th frames in a plasma display device (where i is a natural number) and the ith and (i+1)th frames are each divided into sub-fields each comprising a reset period, an address period, and a sustain period, the method comprising:
- supplying a first main reset pulse during one of the reset periods that is earliest in time in each of the ith frames;
- supplying second and third main reset pulses during consecutive reset periods that are earliest in time in each of the (i+1)th frames;
- and
- supplying a sub-reset pulse during reset periods where one of the first, second, or third main reset pulses is not supplied,
- wherein the first, second, and third main reset pulses have respective first, second, and third maximum voltages that are higher than a maximum voltage of each of the sub-reset pulses and,
- wherein the first main reset pulse has a different duration than the second and third main reset pulses, and the first, second, and third main reset pulses have respective first, second, and third rising periods, where two times the first rising period is greater than the sum of the second and third rising periods.
