  • Patent number: 7414597
    Abstract: A PDP driving circuit for a stable operation of a ramp pulse. A capacitor having a temperature characteristic opposite to a temperature characteristic of a part coupled to a switch that operates as a constant current source for generation of a ramp pulse is arranged in the driving circuit for generating a ramp pulse. The ramp pulse linearly increases or decreases a panel voltage of the PDP with respect to time. Parts having opposite temperature characteristics are coupled in parallel to control variation of a gradient of the ramp pulse so that values of the parts may not be varied depending on the temperature changes. Thus, stable operation of the ramp pulse is obtained.

  • Publication number: 20080174582
    Abstract: In driving a plasma display device, a driving time is accumulatively calculated, and the number of subfields to which a main reset waveform for initializing every discharge cell is supplied in a first frame in which the accumulative driving time is longer than a reference time is larger than the number of subfields to which the main reset waveform is supplied in a second frame in which the accumulative driving time is shorter than the reference time. By increasing the number of subfields to which the main reset waveform is supplied in a single frame with an increase in the accumulative driving time of the plasma display device, a discharge delay can be reduced by using priming particles formed by a main reset.
