Abstract

The present invention discloses a plasma display device that prevents a luminance difference between scan lines by preventing an output voltage fluctuation in output lines connected to a scan IC. The plasma display device includes a plasma display panel having sustain electrodes, scan electrodes, and address electrodes, which are arranged to correspond to discharge cells to selectively drive the discharge cells, a chassis base supporting the plasma display panel, at least one printed circuit board mounted on the chassis base, and at least one flexible printed circuit connecting the scan electrodes to the printed circuit board. The flexible printed circuit includes input lines connecting at least one scan integrated circuit to the printed circuit board, output lines connecting the at least one integrated circuit to the scan electrodes, and ground lines that are formed beside outer sides of outermost output lines among the output lines to ground the at least one scan integrated circuit.

Description

technical field [0001] The present disclosure relates to a plasma display device. More particularly, the present disclosure relates to a plasma display device configured to prevent a difference in luminance between scan lines by preventing fluctuations in output voltages of output lines connected to scan integrated circuits. Background technique [0002] In general, a plasma display device includes: a plasma display panel (PDP) forming an image; a chassis base supporting the PDP; and a plurality of printed circuit boards (PCBs) mounted on the chassis base and connected to the PDP. [0003] The PDP generates plasma using gas discharge, excites phosphors using vacuum ultraviolet rays emitted from the plasma, and realizes images using red, green, and blue visible light generated by stabilization of the excited phosphors. [0004] In order to induce gas discharge, the PDP includes address electrodes and display electrodes (eg, sustain electrodes and scan electrodes). The addre...
