Title:
プラズマディスプレイ装置
Document Type and Number:
Japanese Patent JP3747306
Kind Code:
B2
Abstract:
A plasma display device is comprised of a plasma display panel (10), a circuit board (11, 12) having a driving circuit for driving the plasma display panel, a main frame (17) for supporting the circuit board, and a uniform heat-conducting plate (18) to be fixed to the plasma display panel. In this structure, although the uniform heat-conducting plate is fixed to the plasma display panel by means of, for example, an adhesive, the main frame can be detached from the uniform heat-conducting plate when the plasma display panel is replaced. As a result, various complicated structure such as a radiating fin and a rib can be formed on the main frame because consideration of the possibility of discarding the main frame along with a PDP to be replaced is no longer necessary. By forming the uniform heat-conducting plate to be a simple structure so as to reduce its manufacturing cost, and by forming the main frame to have a complicated structure to improve its thermal nature and the mechanical strength, the present invention is able to realize a plasma display device having improved thermal characteristics and mechanical strength without largely increasing the manufacturing cost.
