Title:
PLASMA DISPLAY DEVICE AND METHOD FOR DRIVING PLASMA DISPLAY DEVICE
Document Type and Number:
WIPO Patent Application WO/2012/073477
Kind Code:
A1
Abstract:
In order to reduce the power consumption of a data-electrode drive circuit in a plasma display device, the data-electrode drive circuit includes, for each data electrode, an output buffer having a high-voltage-side switch that outputs a high-side voltage and a low-voltage-side switch that outputs a low-side voltage. When the voltage of a write pulse is to be transitioned from the low-side voltage to the high-side voltage, the output buffer turns the low-voltage-side switch off and the high-voltage-side switch on and thereby changes the output voltage to the high-side voltage in a first transition period provided in each write cycle. When the voltage of the write pulse is to be transitioned from the high-side voltage to the low-side voltage, the output buffer turns the high-voltage-side switch off and the low-voltage-side switch on and thereby changes the output voltage to the low-side voltage in a second transition period provided in the write cycle. The second transition period and the first transition period immediately after the second transition period are separated temporally.
