Abstract

A plasma display device is provided to enhance operation reliability of the plasma display device by preventing heat from being concentrated on a switching element by implementing an energy recovering circuit in a data driver. A plasma display device includes a plasma display panel(300) and a driver(304). The plasma display panel includes plural address electrodes and plural sustain electrodes, which are formed to intersect the address electrodes. The driver supplies plural data pulses to the address electrodes during an address period, supplies a second data pulse during a period where an inputted image signal has a second load, and supplies at least one first data pulse which has a different waveform from the second data pulse during a period where an inputted image signal has a first load.

Description

technical field [0001] The present invention is an invention related to a plasma display device, more specifically, an invention related to a plasma display device {Plasma Display Apparatus} that reduces the heat generated by a data drive unit that supplies a driving voltage to an address electrode X formed on a plasma display panel during driving. . Background technique [0002] Generally, a plasma display panel consists of a discharge string formed by a barrier formed between the front substrate and the rear substrate, and each discharge string is filled with neon (Ne), helium (He) or a mixed gas containing them (Ne+He), etc. The main discharge gas and a small amount of xenon (Xe) inert gas. Multiple such discharge strings are combined to form a pixel (Pixel). For example, red (Red, R) discharge strings, green (Green, G) discharge strings, and blue (Blue, B) discharge strings are combined to form a pixel. [0003] Moreover, when the plasma display panel is discharged by...
