US 7,768,477 B2 · Plasma display apparatus and driving method of the same

Abstract

In a plasma display apparatus and a method of driving the same which is driven by a driving signal having a reset period, an address period and a sustain period, a sustain pulse is applied during the sustain period, the sustain pulse including: an interval in which the sustain pulse rises from a ground voltage to a first voltage; an interval in which the first voltage is substantially constant for predetermined period of time; an interval in which the sustain pulse rises from the first voltage to a second voltage; and an interval in which the second voltage is substantially constant for a predetermined period of time. At least two discharges can be generated per a single sustain pulse by applying a sustain pulse rising and falling in two stages during one sustain period, and discharge efficiency and luminance can be improved by lengthening a light emission time by maintaining the light generated by a discharge for a predetermined time.

Dependent claims

A plasma display apparatus, comprising:

a first electrode formed on an upper substrate;
and
a first electrode driver for applying a driving signal to the first electrode,
wherein the first electrode driver applies a sustain pulse during a sustain period,
the sustain pulse comprising:
an interval in which the sustain pulse rises from a ground voltage to a first voltage;
an interval in which the first voltage is substantially constant for a predetermined period of time;
an interval in which the sustain pulse rises from the first voltage to a second voltage;
an interval in which the second voltage is substantially constant for a predetermined period of time;
an interval in which the sustain pulse falls from the second voltage to the first voltage after the interval in which the second voltage is substantially constant;
and
an interval in which the sustain voltage falls from the first voltage to the ground voltage, wherein in the interval in which the sustain pulse falls from the second voltage to the first voltage, the voltage decreases by resonation with an inductor provided at the first electrode driver and a panel capacitor.
