Seoul Semiconductor Introduces the World’s Thinnest High-Brightness Chip-LED at 0.17mm
Seoul, S Korea — On Dec 11, Seoul Semiconductor announced that it has launched the world’s thinnest chip-LED at 0.17mm, capable of producing more than two times the brightness of existing chip-LEDs. Seoul Semiconductor has applied for a patent for its new chip.
Seoul Semiconductor’s new chip-LED, WH108, measures 1.6mm in width, 0.8mm in length and 0.17mm in height, and represents a significant reduction in thickness. The WH108 is 15% thinner than the industry’s exiting thin chip-LED, which measures 0.2mm. The WH108 also delivers superior performance at a luminous intensity of 240 mcd, more than two times brighter than the existing chip-LED at a current of 5 mA.
WH108’s ultra-thin package and high brightness make it ideal for use in applications for cell phone keypad modules or touch pads, which will ultimately lead to thinner cell phones.
In addition, the WH108 is capable of producing the same brightness at a lower power, which helps extend the battery life of portable devices such as cell phones, digital cameras and laptops.
The WH108 has enhanced thermal characteristic, meaning it can withstand and perform reliably in demanding environments such as:
- Small lights: inner lighting of refrigerator, reading lamp of automobile
- Special illumination devices: endoscope illumination
- Automobile dashboard lighting
Prototype models of the WH108 in white, blue and green will be available to cell phone companies in Korea and globally in December 2007. Seoul Semiconductor will begin mass-production of the WH108 on a scale of more than 10 million LEDs per month in the first quarter of 2008. More at Seoul Semiconductor.
