<P>PROBLEM TO BE SOLVED: To provide a plasma display device which can relax streaking without spoiling brightness, with respect to an AC type plasma display device. <P>SOLUTION: In the AC type plasma display device in which one frame is constituted of two or more sub-fields and an image is displayed by generating a maintenance discharge two or more times across display electrodes in each sub-field, a period of generating the maintenance discharge two or more times in each sub-field consists of two or more maintenance discharge periods differing in a single-generated maintenance discharge current, for example, maintenance discharge periods in which the single-generated maintenance discharge current is low, and maintenance discharge periods in which a single-generated maintenance discharge current is high, and the AC type plasma display device has a driving circuit which increases a percentage of the discharge frequency of the maintenance discharge periods in which the single-generated discharge current is high compared with the maintenance discharge periods in which the single-generated maintenance discharge current is low, as a total frequency of the maintenance discharges increases. <P>COPYRIGHT: (C)2007,JPO&INPIT |
