Plasma display device with heat dissipation channels

A plasma display device comprising:

• a plasma display panel having a front side and a rear side, the front side of the plasma display panel being used for displaying images;
• a rectangular side frame comprising upper, lower, left and right bars over which the plasma display panel is vertically installed at a front end of the four bars of the side frame;
• a rear plate vertically installed in a rear end of the four bars of the side frame;
• a circuit board electrically connected to the plasma display panel for controlling image displays of the plasma display device, the circuit board having a first width;
• and
• a supporting rack installed inside the side frame between the plasma display panel and the rear plate comprising a horizontal top beam fixed at the upper bar of the side frame, a horizontal bottom beam fixed at the lower bar of the side frame, and a plurality of vertical columns mounted between the top beam and bottom beam, the rear side of the plasma display panel being fixed on a front end of the plurality of vertical columns;
• wherein a heat dissipation channel is formed between two neighboring vertical columns, and the heat dissipation channel has a second width,
• wherein, the first width is smaller than the second width so that the circuit board is positioned within the heat dissipation channel formed between two neighboring vertical columns, and the circuit board thus is spaced apart from the plasma display panel and the rear plate.
