SDK reflector suits LCDs in PCs, TV sets

Showa Denko K.K. (SDK) has developed a high-performance aluminum reflector for liquid crystal displays (LCDs) for use in personal computers and television sets.

An extension of the company's ST-60 aluminum alloy with high thermal diffusivity comparable to that of pure aluminum, the reflector is manufactured by providing proprietary white coating on ST-60 sheet. Compared with conventional aluminum alloy to which white film of polyethylene terephthalate is attached, the newly reflector offers higher heat dissipation efficiency and light resistance, as well as reflectivity of >95 percent.

The white coating is also capable of absorbing ultraviolet, resulting in the reduction of ultraviolet radiation toward the front of the display unit. And since coating is possible even after press working, SDK will be able to produce reflectors that are complex in shape and serve as chassis as well.
