Heat issues delay adoption of high-power LEDs

Share

The adoption of LEDs (light-emitting diodes) in high-brightness panel applications such as laptops and LCD televisions has been delayed due to overheating issues, according to sources in the LED industry in Taiwan.

To minimize the temperature coming from the back of the illuminated modules, LED companies are testing various solutions that could reduce the heat. But improving heat management will inevitably increase material cost, sources say.

Due to technology requirements and cost issues, LED adoption will not reach the notebook market until the fourth quarter of 2006, while adoption in the large LCD TV segment will increase after the second quarter of 2007 , according to sources.
