Abstract
A PDP driving circuit is disclosed. The circuit includes a scan driver divided into at least more than two groups, a logic controller generating scan driver control reference signals, which are used to generate scan driving signals of the scan driver, and a buffer block giving different delay times to the scan driver control reference signals, to apply them to the scan driver groups, respectively.
Claims21
A plasma display panel (PDP) driving circuit comprising:
- a logic controller generating a plurality of scan driver control reference signals;
- a buffer block having different delay times for each of the scan driver control reference signals;
- and
- a scan driver divided into at least three groups and configured to generate scan driving signals for each of the groups based on each of the delayed scan driver control reference signals.

A driving method for a plasma display panel (PDP) comprising a logic controller and a plurality of scan drivers, the method comprising:
- generating a plurality of scan driver control reference signals in a logic controller, the reference signals being digital signals;
- transferring the scan driver control reference signals to the scan drivers, the transferred reference signals having a delay time in at least one transition time point;
- generating a plurality of scan driving signals according to the transferred scan driver control reference signals;
- and
- driving the PDP according to the scan driving signals.
2 more elements
A plasma display device comprising:
- a plasma display panel (PDP) including a plurality of discharge electrodes, each of the discharge electrodes belonging to one of more than two groups;
- and
- a driving circuit module configured to separately drive each of the groups of discharge electrodes with driving signals each including a reset waveform, an address waveform, and a sustain waveform,
- wherein at least one of the reset waveform, the address waveform, and the sustain waveform is applied to each of the groups at a different time.
