Solvay unveils high-performance polyester material for LED TV components
extended its line of high-performance polyester compounds with a new version targeting light-emitting diode (LED) TVs with higher heat and light stability. Seeking to reduce product costs, TV manufacturers are finding ways to reduce the number of LEDs by sending more amps through the devices to hike brightness. (Another cost-lowering strategy: go the other way and give up some brightness in LED backlit models.) This raises the junction temperatures, though, and some materials can't handle the higher heat and light output, e.g. discoloring more quickly in applications such as reflector cups.
