摘要： Provided are a plasma display panel driving method, which can perform a stable high-speed write while suppressing the rise of a black brightness over a wide temperature range and independently of a power accumulative time period from the beginning of the use, and a plasma display device. The method drives a panel, which is provided, for one field period, with all cell initialization subfields for generating an initialization discharge to all discharge cells for performing an image display for an initialization period, and a selective initialization subfield for generating an initialization discharge selectively with the discharge cells having generated a maintenance discharge in the immediately preceding subfield for the initialization period. The method can increase/decrease the numbers of all cell initialization subfields, and can vary the initialization voltage for generating the initialization discharge in all the cell initialization subfields. Either the number of all the cell initialization subfields of at least one field or the initialization voltage of all the cell initialization subfields is controlled on the basis of the accumulation of the time periods, for which the panels were energized.

The second step is to set the peak electric potential of the reset pulse to first peak electric potential during the reset distance of the first unit display period. The third step is to the peak electric potential as the second peak electric potential for the reset administration of the second unit display period.

摘要： A plasma-display-panel driving method is provided with a plurality of sub-fields in one field period. The sub-fields are comprised of a writing period during which writing discharges take place selectively at discharge cells and a discharge maintaining period during which maintaining discharges are carried out repeatedly in proportion to brightness weights at the writing discharge cells. In the maintaining period, a period is provided between the last maintaining pulse and the maintaining pulse immediately before the last to hold a pair of display electrodes at a base potential. Further, after a voltage to generate the last maintaining discharge is supplied to a pair of display electrodes, a time interval is set in response to a turn-on rate of discharge cells in the sub-field and a voltage is applied to a pair of display electrodes to ease a potential difference between a pair of display electrodes. This method carries out stable writing discharges without increase of voltages necessary for writing discharges and reduces crosstalk.

摘要： A light emitting display device, an electronic apparatus, and a device and a program for correcting burn-in are provided to perform an exact correction operation by performing a gamma correction on grayness values of overall pixels in order to reduce estimation deterioration amounts. A deterioration amount difference producing unit(313) produces a deterioration amount difference between corrected pixels and reference pixels during a first light emitting period. A correction amount producing unit(317) produces correction amounts, which are required for correcting the deterioration amount difference during a second light emitting period, based on estimation deterioration amounts. A deterioration amount difference correction unit(319) corrects grayness values. A gamma conversion unit(335) performs a gamma conversion on the corrected grayness values and supplies the converted grayness values to a display panel. A deterioration amount producing unit(331) receives the grayness values and produces real deterioration amounts. An estimation error detector(333) detects error amounts and adjusts the gamma conversion unit so as to prevent the detected error.
