Abstract
The present invention relates to a PDP device, and mainly provides a technique for preventing occurrence of flicker (in particular, line flicker in an interlace display). In the present PDP device, by control operation in a control circuit, in each of odd numbered and even numbered fields of the conventional art, both odd numbered and even numbered display line groups are continuously driven in a first half and a second half based on the same data (data of the odd numbered display line) as a new field structure.

A plasma display panel driving method of performing display drive control including specification of display data to be used in a display line group to be a subject of drive-displaying with respect to a plasma display panel in which a display region including odd numbered and even numbered display line groups is constructed by a matrix of display cells of an electrode group,
- wherein a field associated with the display region and a period is constructed in a structure temporally divided into a plurality of sub-fields for gray-scale expression, and
- wherein based on a structure of the field time-dividing an image frame to be displayed by the odd numbered and even numbered display line groups of the display region, for at least one set of adjacent odd numbered and even numbered display lines in the display line group of the display region, both odd numbered and even numbered display lines of the set are drive-displayed continuously in a time division manner using display data of only one of the odd numbered and the even numbered display lines of the set in the field.
A plasma display device comprising:
- a plasma display panel including a substrate over which a plurality of first and second electrodes to be used in sustain discharge is alternately arranged in a second direction with a structure extending parallel to a first direction, a plurality of third electrodes to be used in address discharge is arranged with a structure extending parallel to the second direction, an odd numbered display line is composed of a pair of the first and the second electrodes adjacent on one side in the second direction, an even numbered display line is composed of a pair adjacent on the other side, and a display cell is constructed at an intersection of the display lines and the third electrode;
- and
- a circuit section including a control circuit performing display drive control including specification of display data to be used in a display line group to be a subject of drive-displaying and drive circuits for applying voltage for driving to the first, the second, and the third electrode groups respectively,
- wherein a field associated with a display region and a period of the panel is constructed in a structure temporally divided into a plurality of sub-fields each having an address period and a sustain period for gray-scale expression, and
- wherein based on a structure of a field time-dividing an image frame to be displayed by the odd numbered and even numbered display line groups of the display region, for at least one set of adjacent odd numbered and even numbered display lines in the display line group of the display region, the circuit section drive-displays both odd numbered and even numbered display lines of the set continuously in a time division manner using display data of only one of the odd numbered and the even numbered display lines of the set in the field.
