Abstract
The present method is to drive a plasma display panel which displays a frame composed of a plurality of sub-fields having different weights of luminance. The method comprises using plural kinds of application voltage waveforms different in light emission luminance, as pulse voltages for sustain discharges in display of each sub-field, and adjusting the number of waves in each of the plural kinds of application voltage waveforms according to the weight of luminance set for each sub-field, thereby performing gradation display.
Claims5
A method for driving a plasma display panel which displays a frame by replacing the frame with a plurality of sub-fields assigned weights of luminance and applying a sustain pulse to a display electrode X and a display electrode Y alternately, the method comprising:
- applying plural kinds of sustain pulses different in light emission luminance to the display electrode X and the display electrode Y in display of each sub-field;
- and
- differentiating a constituent ratio of the plural kinds of sustain pulses in accordance with a gradation level of a frame of a display image.
A method for driving a plasma display panel which displays a frame by replacing the frame with a plurality of sub-fields assigned weights of luminance and applying a sustain pulse to a display electrode X and a display electrode Y alternately, the method comprising:
- applying plural kinds of sustain pulses different in light emission luminance to the display electrode X and the display electrode Y in display of each sub-field;
- and
- when a display rate of a display image is a second display rate higher than a first display rate, increasing a constituent ratio of a sustain pulse smallest in light emission luminance of the plural kinds of sustain pulses to be larger than the case where the display rate is equal to the first display rate, and decreasing a constituent ratio of any other sustain pulse than the sustain pulse smallest in light emission luminance to be smaller than the case where the display rate is equal to or higher than the first display rate.
