Abstract

A plasma display device is driven by dividing a plurality of row electrodes into first and second row groups. A first row group of electrodes are divided into a plurality of first sub-groups, and a second row group of row electrodes are divided into a plurality of second sub-groups. During a first subfield of a first group of subfields, non-light emitting cells are selected from light emitting cells of a first sub-groups and light emitting cells of a second sub-groups are sustain-discharged during a first period. In addition, during the first subfield, the non-light emitting cells are selected from the second sub-group, and the light emitting cells of a first sub-group are sustain-discharged during a second period. With such an operation, a length of one subfield can be reduced because another row group is sustain-discharged while one row group is being selected as the non-emitting cells.

Description

technical field [0001] The invention relates to a plasma display device and a driving method thereof. Background technique [0002] A plasma display device is a flat panel display that displays characters or images using plasma generated through a gas discharge process. It includes a plurality of discharge cells arranged in a matrix pattern. [0003] On a panel of a plasma display device, a field (for example, a 1TV field) is divided into a plurality of subfields each having a weight. Gray scales are represented by a combination of weights of subfields that generate display operations among subfields. Each subfield has an addressing phase and a sustaining phase. In the addressing phase, the addressing operation selects a discharge cell that emits light and a discharge cell that does not emit light among a plurality of discharge cells. In the sustaining phase, it occurs in the selected discharge cell. The sustain discharge is performed to perform a...
