AI Technical Summary

Problems solved by technology

Some of the electrical energy used in the plasma discharge is converted into light, but most of the electrical energy is converted into heat and dissipated in the plasma display panel
However, as the temperature of the plasma display panel increases, the fluorescent material used to manufacture the plasma display panel degrades or deforms, resulting in a shortened service life of the plasma display panel
In addition, when the plasma display panel is overheated, especially when the plasma display panel is partially overheated, the glass substrate of the plasma display panel will thermally expand, causing the glass substrate to be subjected to stress, resulting in cracking of the glass substrate
[0007] In order to obtain images, the drive circuit connected to the electrodes of the plasma display panel consumes a large amount of power
Power consumption generates heat and can malfunction if the drive circuit overheats
For example, some pixel parts may emit light even though they are not intended to emit light, degrading the image quality as a result

Abstract

In a plasma display device, a coupling structure for coupling front and rear covers is modified so that an empty space is formed between the front and rear covers, and a heat sink making contact with a driving chip of a signal line connecting an electrode of a display panel with a driving circuit extends along the empty space, thereby improving the heat dissipation efficiency of the driving chip.

Description

[0001] priority claim [0002] This application references, is hereby incorporated and claims priority to Application "Plasma Display Device" with duly assigned Serial No. 10-2005-0040423 filed on May 14, 2005 in the Korean Intellectual Property Office. technical field [0003] The present invention relates to plasma display devices. More particularly, the present invention relates to a plasma display device capable of improving heat dissipation characteristics of a driving chip provided on a signal line connecting an electrode of a plasma display panel to a driving circuit driving the electrode. Background technique [0004] As generally known in the art, a plasma display device refers to a flat panel display device using a plasma display panel (PDP). The plasma display panel can be obtained through the following steps: electrodes are formed on two opposite substrates, and the The two substrates are overlapped with each other so that a predetermined space is formed therebe...
