PRE-AMPLIFIER NOISE SHIELD STRUCTURE FOR PLASMA DISPLAY PANEL INCLUDING PRE-AMPLIFIER SHIELD CASE WITH ELASTIC PROTRUSIONS

摘要

PURPOSE: A pre-amplifier noise shield structure is provided to achieve improved noise shield effect by permitting a plasma display panel filter and a heat sink to stably contact with each other. CONSTITUTION: A pre-amplifier noise shield structure comprises a pre-amplifier shield case(100) for shielding a remote control signal receiving unit from noises; a plasma display panel filter(200) for supporting one surface of the shield case during installation of the shield case in a plasma display panel; and a heat sink(300) for supporting the other surface of the shield case and discharging heat generated from the plasma display panel during installation of the shield case. The pre-amplifier shield case has an elastic protrusion(100a) which elastically contacts the plasma display panel filter and the heat sink during installation of the shield case.
