AI Technical Summary

Problems solved by technology

However, the cooling efficiency of this heat sink is low
For this, there is the problem that the size of the heat sink relative to the driver IC must be large enough to dissipate the large amount of heat generated by the TCP driver IC

Abstract

A plasma display apparatus includes: a plasma display panel; a chassis base arranged parallel to the plasma display panel; a driver IC electrically connecting electrodes of the plasma display panel to a driving circuit, the driver IC adapted to supply voltage signals to the electrodes of the plasma display panel in accordance with signals from the driving circuit; and a heat dissipating plate arranged adjacent to the driver IC and facing the chassis base to interpose the driver IC between the chassis base and a heat dissipating plate; wherein the heat dissipating plate includes an accommodating portion adapted to accommodate the driver IC on a side surface thereof opposite to the driver IC.

Description

technical field [0001] The present invention relates to a plasma display device, and more particularly, to a plasma display device including a heat dissipation plate to efficiently transfer heat generated by a driver IC. Background technique [0002] Generally, a plasma display device has a plasma display panel that displays a desired image using plasma generated by gas discharge. The plasma display panel has electrodes electrically connected to a driving circuit, and supplies a voltage signal to a driver IC of the electrodes according to a signal output from the driving circuit. [0003] The voltage application structure using a driver IC includes: a chip-on-board (COB) structure in which a driver IC is mounted on a printed circuit board (PCB); and a chip-on-film structure in which a driver IC is directly mounted on a flexible printed circuit (FPC) film (COF) structure. Now, a small-sized and low-cost tape carrier package (TCP) is widely used as a voltage applying structu...
