Abstract
A method and circuit for driving a plasma display panel are provided which are capable of preventing a useless display, irrespective of characteristics of a driving power source. In the method for driving the disclosed plasma display panel, a pulse having an erasing pulse which causes a maximum potential difference between sustaining electrodes being adjacent to each other to reach at least sustaining voltage is applied, immediately after power is applied, to a scanning electrode.
Claims18
A method for driving a plasma display panel, said plasma display panel including a plurality of pairs of surface discharge electrodes each said pair of said surface discharge electrodes being made up of a scanning electrode and a sustaining electrode and each said scanning electrode and said sustaining electrode being formed successively in a column direction and being parallel to a row direction and a plurality of data electrodes each being formed successively in the row direction and being parallel to said column direction, forming pixels at intersections of said plurality of said data electrodes and said plurality of said pairs of surface discharge electrodes, and discharge space existing in a gap between a plane on which said plurality of said pairs of said surface discharge electrodes is formed and a plane on which said plurality of said data electrodes is formed, comprising:
- a step of applying, immediately after power is turned ON, a pulse having an erasing pulse which causes a maximum potential difference between said sustaining electrode and said scanning electrode being adjacent to each other to reach at least a sustaining voltage, to said scanning electrode.
A circuit for driving a plasma display panel, said plasma display panel having a plurality of pairs of surface discharge electrodes each said pair of said surface discharge electrodes being made up of a scanning electrode and a sustaining electrode and each said scanning electrode and said sustaining electrode being formed successively in a column direction and being parallel to a row direction and a plurality of data electrodes each being formed successively in said row direction and being parallel to said column direction, forming pixels at intersections of said plurality of said data electrodes and said plurality of said pairs of said surface discharge electrodes, and discharge space existing in a gap between a plane on which said plurality of said pairs of surface discharge electrodes is formed and a plane on which said plurality of said data electrodes is formed, comprising:
- a controller to produce, immediately after power is turned ON, a control signal used to apply a pulse having an erasing pulse which causes a maximum potential difference between said sustaining electrode and said scanning electrode being adjacent to each other to reach at least a sustaining voltage, to said scanning electrode.
