Abstract
A method for driving a plasma display panel is provided in which a time necessary for an addressing process is shortened without using any special driving component. The method comprises an addressing process that includes the steps of setting light emission operation of the cells of a display of one screen, starting j-th row selection at a point during (j−1)th row selection, and changing the data electrodes from a control state corresponding to display data of the (j−1)th row to a control state corresponding to display data of the j-th row during a period in which the (j−1)th row selection and the j-th row selection are overlapped with each other.
Claims5
A method for driving a plasma display panel having cells for a matrix display made of n rows and m columns, scan electrodes for selecting a row and data electrodes for selecting a column, the method comprising an addressing process that includes the steps of:
- selecting a row by biasing a scan electrode corresponding to a selected row among the data electrodes to a selecting potential for a constant period sequentially for all rows;
- controlling potentials of the data electrodes in accordance with display data of the corresponding row in synchronization with the row selection of each row, so that light emission operation of the cells of a display of one screen is set;
- starting j-th (2≦j≦n) row selection at a point during (j−1)th row selection;
- and
- changing the data electrodes from a control state corresponding to display data of the (j−1)th row to a control state corresponding to display data of the j-th row during a period in which the (j−1)th row selection and the j-th row selection are overlapped with each other.
A plasma display device comprising a plasma display panel and a driving circuit for driving the plasma display panel, wherein
- the plasma display panel includes cells for a matrix display made of n rows and m columns, scan electrodes for selecting a row and data electrodes for selecting a column, and
- the driving circuit selects a row by biasing a scan electrode corresponding to a selected row among the data electrodes to a selecting potential for a constant period sequentially for all rows, controls potentials of the data electrodes in accordance with display data of the corresponding row in synchronization with the row selection of each row, so that light emission operation of the cells of a display of one screen is set, starts j-th (2≦j≦n) row selection at a point during (j−1)th row selection, and changes the data electrodes from a control state corresponding to display data of the (j−1)th row to a control state corresponding to display data of the j-th row during a period in which the (j−1)th row selection and the j-th row selection are overlapped with each other.
