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.

Due to technology requirements and cost concerns, LED adoption will not penetrate the notebook market until the fourth quarter of 2006, while adoption in the large-size LCD TV segment will phenomenally increase after the second quarter of 2007, according to the sources. The speculation was offered in response to a June 15 article, which cited the chairman of Taiwan's largest LED packaging firm Everlight Electronics, Robert Yeh, as indicating that the company's scheduled shipments of white LEDs used in notebooks and larger-size LCD TVs will be pushed back to the second half of 2007.
