Thermal heat spreader for plasma screens

GrafTech International Ltd. in Cleveland is offering the eGraf SpreaderShield natural graphite thermal heat spreaders to eliminate potential hot-spot problems and improve temperature uniformity across large-screen plasma displays and other flat-panel displays. Hot spots can happen in plasma displays when an image remains static for a significant period of time, company officials say. Varying temperature profiles across the screen can lead to uneven picture brightness over time. For more information contact GrafTech online at
