Abstract
A method of driving a plasma display panel in which a normal operation is not impeded and an erroneous discharge, that may damage the panel, will never occur even when flicker is suppressed in a PDP employing an ALIS system. Some subfields that make up a display field of a frame, that is, a subfield of a first group, are represented by first display lines and the rest, that is, a subfield of a second group, are represented by second display lines; thus, a total display field is obtained and a gray scale is represented.
Claims20
A one-sided field method of driving a plasma display panel having plural first and second electrodes arranged adjacently by turns, wherein:
- a first display line is formed between one side of the first electrode and one of the second electrodes adjacent to the one side, and a second display line is formed between the other side of the said first electrode and another one of the second electrodes adjacent to the other side;
- a display field of a frame comprises a set of subfields to be used for display with gray scale and, a desired gray scale is represented by combining subfields, each of which is selected for display from the set of subfields;
- the set of subfields comprises one or more subfields represented by the first display lines and another one or more subfields represented by the second display lines;
- and
- each subfield is represented by a combination of only the first display lines or a combination of only the second display lines.
A plasma display apparatus having plural first and second electrodes arranged adjacently by turns, comprising:
- a first display line formed between one side of the first electrode and one of the second electrodes adjacent to the one side, and a second display line formed between the other side of the said first electrode and another one of said second electrodes adjacent to the other side;
- a display field of a frame comprises a set of subfields to be used for display with gray scale, a desired gray scale being represented by combining subfields, each of which is selected for display from the set of subfields when a one-sided field driving method is performed;
- the set of subfields comprises one or more subfields represented by the first display lines and another one or more subfields represented by the second display lines;
- and
- each subfield is represented by a combination of only the first display lines or a combination of only the second display lines.
A one-sided field method of driving a plasma display panel having plural first and second electrodes arranged In an alternating, adjacent and parallel relationship, comprising plural first and second display lines formed on respective, first and second opposite sides of each first electrode and respectively between the first electrode and the respective, alternate second electrodes adjacent the first and second opposite sides of the first electrode, the method comprising:
- defining a display field of a frame to comprise a set of subfields to be used for a gray scale display and producing a desired gray scale display by selectively combining subfields selected for display from the set of subfields;
- defining each set of subfields to comprise one or more subfields represented by the first display lines and another one or more subfields represented by the second display lines;
- and
- representing each subfield by using a combination of only the first display lines or a combination of only the second display lines.
A plasma display apparatus having plural first and second electrodes arranged in an alternating, adjacent and parallel relationship and driven by a one-sided driving method, comprising:
- plural first and second display lines formed on respective, first and second opposite sides of each first electrode and respectively between the first electrode and the respective, alternate second electrodes adjacent the first and second opposite sides of the first electrode;
- a unit defining a display field of a frame to comprise one set of subfields to be used for a gray scale display and producing a desired gray scale display by selectively combining subfields selected for display from the set of subfields;
- a unit defining each set of subfields to comprise one or more subfields represented by the first display lines and another one or more subfields represented by the second display lines;
- and
- a unit representing each subfield by using a combination of only the first display lines or a combination of only the second display lines.
