Abstract:
1. A plasma display apparatus comprising: a panel including a transparent front substrate and an opposing rear substrate, the front substrate and the rear substrate arranged to form a discharge space therebetween, and the front substrate and the rear substrate having a plurality of electrodes provided thereto; a display driving circuit block disposed on a chassis, having an input signal connector, and operable to apply a signal to said panel to display an input signal thereon; an input signal circuit block coupled to said display driving circuit block, disposed on the chassis, operable to receive a video signal from an external apparatus, and including (i) a case arranged substantially in parallel with said panel and having a mounting port, and (ii) a detachable block unit detachably mounted to said case via said mounting port, having a signal output connector for coupling with said input signal connector of said display driving circuit block, and having an input terminal for detachably connecting to the external apparatus; and a housing arranged to accommodate said panel, said display driving circuit block, and said input signal circuit block including said case, and said detachable block unit, wherein: said mounting port of said case is open to an outside of said housing and arranged to receive said detachable block unit from the outside of said housing such that said detachable block unit is arranged substantially in parallel with said panel; said mounting port receiving said detachable block unit results in said detachable block unit being detachably mounted to said case and said output connector of said detachable block unit detachably coupled to said signal input connector of said display driving circuit block; said detachable block unit includes (i) a circuit board having electronic components forming an electronic circuit on opposite surfaces thereof, and (ii) upper and lower shielding plates respectively mounted to said opposite surfaces of said circuit board having said electronic circuit thereon and arranged to cover and electromagnetically shield the electronic components and dissipate heat generated from the electronic components; and said upper and lower shielding plates are substantially the same size and arranged at an identical position on said opposite surfaces of said circuit board.
