Abstract:
1. A method of driving a plasma display panel in which one frame comprises a plurality of sub-fields that cause a gray level of light to be emitted according to brightness weights allocated to the sub-fields, wherein the method includes: implementing a specific gray level using a same luminous pattern that corresponds to a previous or next gray level relative to the specific gray level, wherein the luminous pattern for the previous gray level has an on-state value for a first set of consecutive sub-fields beginning with a first sub-field and has an off-state value for a second set of consecutive sub-fields following the first set of sub-fields, wherein the luminous pattern for the next gray level has an on-state value for a set of non-consecutive sub-fields and an off-state value for all remaining sub-fields, and wherein the previous gray level is a gray level that comes before the specific gray level and the next gray level is a gray level that comes after the specific gray level.
