Abstract
This invention relates to a driving apparatus of a plasma display panel that is capable of being operated stable, regardless of temperature. A driving apparatus of a plasma display panel according to the present invention includes a panel having a scanning electrode for receiving a scanning pulse in an address period and an address electrode for receiving a date pulse synchronized with the scanning pulse in the address period; and a pulse width controller for changing the width of the scanning pulse when the panel is driven at a low temperature.
Claims18
A method of driving a plasma display panel, comprising:
- applying a first scanning pulse in an address period and a first sustaining pulse in a sustain period in at least one subfield of a first frame at a first temperature;
- applying a second scanning pulse in an address period and a second sustaining pulse in a sustain period in at least one subfield of a second frame at a second temperature, wherein the second temperature is lower than the first temperature, and
- wherein a number of subfields of the second frame is different from that of the first frame and wherein a width of the second sustaining pulse is substantially same as a width of the first sustaining pulse.
A method of driving a plasma display panel, comprising:
- applying a first scanning pulse in an address period and a first sustaining pulse in a sustain period in at least one subfield of a first frame at a first temperature;
- applying a second scanning pulse in an address period and a second sustaining pulse in a sustain period in at least one subfield of a second frame at a second temperature, wherein the second temperature is lower than the first temperature, and
- wherein a number of subfields of the second frame is different from that of the first frame and wherein a number of sustain pulses in at least one subfield of the second frame is the same as a number of sustain pulses in at least one subfield of the first frame.
