Abstract
A plasma display and a driving method for the plasma display. The plasma display is constructed with a control type plasma display panel having a closed barrier rib configuration, and each pair of column-wise neighboring discharge cells have different electrode arrangement. In the driving method, when the control type plasma display panel has an alignment error for a first electrode and a second electrode, a scan pulse having a first width is applied to an odd-numbered first electrode, and the scan pulse having a second width that is different from the first width is applied to an even-numbered first electrode.
Claims10
A driving method for a plasma display,
- with the plasma display having a closed barrier rib configuration and comprising a plurality of first and second electrodes, a plurality of third electrodes formed crossing the first and second electrodes, and a plurality of discharge cells formed at crossing regions of the first, second, and third electrodes,
- with the driving method comprising:
- during an address period of a subfield, applying a scan pulse having a first width to odd-numbered first electrodes;
- and
- applying a scan pulse having a second width that is different from the first width to the even-numbered first electrodes, the second width being wider than the first width when an area of an odd-numbered first electrode within a discharge cell is greater than an area of an even-numbered first electrode within the discharge cell.
A plasma display, comprising:
- a plasma display panel having a closed barrier rib configuration comprising a plurality of first and second electrodes, a plurality of third electrodes formed crossing the first and second electrodes, and a plurality of discharge cells formed at crossing regions of the first, second, and third electrodes,
- a controller dividing one frame into a plurality of subfields and driving the subfields, with each subfield comprising a reset period, an address period, and a sustain period, and driving the subfields;
- and
- a first electrode driver for generating scan pulses according to a control operation of the controller, and applying the scan pulses to the plurality of first electrodes during the address period, with the first electrode driver applying the scan pulses having a first width among the scan pulses to odd-numbered first electrodes, and applying the scan pulses having a second width that is different from the first width to even-numbered first electrodes, the second width being wider than the first width when an area of an odd-numbered first electrode within a discharge cell is greater than an area of an even-numbered first electrode within the discharge cell.
