Abstract
The driving apparatus for a plasma display panel is formed by a first priming pulse generation circuit for generating a first priming pulse having a first crest value; a second priming pulse generation circuit for generating a second priming pulse having a second crest value; and a drive control means for selectively controlling the first priming pulse generation circuit so as to output the first priming pulse and second priming pulse generation circuit so as to output the second priming pulse in accordance with a detection result obtained from the intensity detection means.
Claims6
A driving apparatus for a plasma display panel having a sustaining electrode and a scanning electrode comprising:
- an intensity detection means for detecting an average intensity of a display image to be displayed on said plasma display panel;
- a first priming pulse generation circuit for generating a first priming pulse having a first crest value which is applied between said sustaining electrode and scanning electrode in a priming period for driving said plasma display panel;
- a second priming pulse generation circuit for generating a second priming pulse having a second crest value which is applied between said sustaining electrode and scanning electrode in said priming period for driving said plasma display panel;
- and
- a drive control means for selectively controlling said first priming pulse generation circuit so as to output said first priming pulse and second priming pulse generation circuit so as to output said second priming pulse in accordance with a detection result obtained from said intensity detection means.
A driving apparatus for a plasma display panel having a sustaining electrode and a scanning electrode comprising:
- an intensity detection means for detecting an average intensity of a display image to be displayed on said plasma display panel;
- a priming pulse generation circuit for generating a first priming pulse having a first pulse width and a second priming pulse having a second pulse width which are applied between said sustaining electrode and scanning electrode, respectively, in a priming period for driving said plasma display panel;
- and
- a drive control means for controlling said priming pulse generation circuit so as to selectively output said first priming pulse or second priming pulse in accordance with a detection result obtained from said intensity detection means.
A driving method for a plasma display panel having a sustaining electrode and a scanning electrode comprising the steps of:
- detecting an average intensity of a display image to be displayed on said plasma display panel;
- generating a first priming pulse having a first crest value in case of detecting that said average intensity of said display image to be displayed is higher than a prescribed intensity in said detecting step;
- generating a second priming pulse having a second crest value, a crest value of which is smaller than that of said first priming pulse, in case of detecting that said average intensity of said display image to be displayed is lower than said prescribed intensity in said detecting step;
- and
- applying said first priming pulse or second priming pulse between said sustaining electrode and scanning electrode in a priming period.
A driving method for a plasma display panel having a sustaining electrode and a scanning electrode comprising the steps of:
- detecting an average intensity of a display image to be displayed on said plasma display panel;
- generating a first priming pulse having a first pulse width in case of detecting that said average intensity of said display image to be displayed is higher than a prescribed intensity in said detecting step;
- generating a second priming pulse, a pulse width of which is narrower than that of said first priming pulse, in case of detecting that said average intensity of said display image to be displayed is lower than said prescribed intensity in said detecting step;
- and
- applying said first priming pulse or second priming pulse between said sustaining electrode and scanning electrode in a priming period.
