A more cost-effective and environmentally friendly solution to traditional incandescent holiday lighting is now available, says newly launched LED Christmas light company HolidayLEDs.com.
Sumitomo Chemical Company and Cambridge Display Technology Inc., a developer of technologies based on polymer organic light emitting diodes (P-OLEDs), today jointly announced that Sumitomo Chemical has completed its $285 million acquisition of CDT, by means of a merger between CDT and a wholly owned subsidiary of Sumitomo Chemical. The merger consideration represents a 107 percent premium over CDT's 90-day average closing share price and a 95 percent premium over CDT's closing share price of $6.15 on July 30, the last trading day prior to first public announcement of the acquisition.
Some new technologies appear from nowhere. Others are heralded by such long fanfares that it seems they will never arrive. Electronic paper is surely in the second category. The idea of a display screen that has the clarity and flexibility of paper has been around for at least a decade. It has found a few niche, black-and-white applications in mobile phones and ¡§electronic books¡¨. As a mass-market, full-colour product, however, it has conspicuously failed to show up.
Even if the next LCD you buy has pretty much the same characteristics as the last LCD you bought, a change is likely to have occurred behind the scenes. In display sizes below about 15 inches, the tried-and-true cold-cathode fluorescent lamp (CCFL) lighting system for the LCD is rapidly being replaced by light-emitting diodes.
National Semiconductor Corporation will showcase its latest power management technology at the Portable Design Conference and Exhibition in Santa Clara, California, from October 3-4. The Portable Design Conference is the only industry gathering of design engineers specifically engaged in the development and engineering of portable devices.
Researchers in Hong Kong claim to have developed the highest power efficiency non-doped white organic light emitting device (WOLED) made using a single white-emitting material. They believe that their high purity, color stable device, surpasses existing WOLEDs and is a more efficient and environmentally friendly alternative to inorganic LEDs.
Cooling the skin to protect it from hyperpigmentation after laser treatment actually increased discoloration in dark-skinned patients, researchers reported.
A calibration service company has recently upgraded its laser calibration system with a laser interferometer, which minimises transportation and set-up times.
Seoul Semiconductor, the eighth-largest LED manufacturer in the world, announced today worldwide release of an upgraded version of Acriche, the world's first semiconductor lighting source for AC power outlets in US, Europe and Asia. The new Acriche, package type emitting 200 lumens, is being provided as an emitter with features including higher brightness of 200 lumens at 3.3 Watt, which is nearly 60 lm/W or 50% brighter than the version released last November. Due to its advanced high-yield device fabrication methods and the economics of high capacity, Seoul Semiconductor is able to reduce the price of the enhanced version of Acriche by 40%, making it more competitively priced to penetrate the conventional lighting market.
Visible and ultraviolet laser light has been used for years to cool trapped atoms--and more recently larger objects--by reducing the extent of their thermal motion.
