Heat concerns slow high-power LED adoption

Adoption of light-emitting diodes (LEDs) in high brightness panel backlighting applications, such as notebooks and LCD TVs, has been delayed due to overheating issues, according to sources in the Taiwan LED industry. In order to minimize the temperature that comes from the back of panel backlight modules, LED packaging firms are vying for various solutions that can reduce heat as much as possible, but material costs inevitably increase as heat management improves, indicated the sources.
