Posco Develops Heat-Radiating Steel Plates for LED TVs
11/01/2011 - Posco has developed a surface-prepared steel sheet coated at a thickness of one-fiftieth of a strand of hair, with excellent heat radiation performance, to be used as an internal panel material for LED TVs.
Posco claims to be the first company to develop a surface-prepared steel sheet coated at a thickness of one-fiftieth of a strand of hair, with excellent heat radiation performance, to be used as an internal panel material for LED TVs.
LED TVs traditionally have used aluminum board material instead of steel for its characteristic of conducting heat. Posco started its research in 2010 and succeeded in developing this technology after 1 year, 6 months. The core of this product is the heat-radiating resin solvent that maintains the high processability and stiffness unique to steel while improving heat conductivity and radiation. These solvent and coated steel sheets were patented in July 2011.
This new steel plate, called POSCOTE-RH (Posco Smart COating TEchnology-Radiating Heat), will be used not only for high-end TV material; the company also plans to expand its application to other home video electronics and as part materials to appliances that generate problematic heat.
POSCOTE-RH is said to be 10-15% cheaper than aluminum panels and allow additional cost reduction from removing the stage of separately attaching heat-radiation parts.
Posco also succeeded in developing what it claims is the world’s first high-gloss plated steel sheet using UV rays in August 2011.
