The SAM9G45 evaluation kit from Atmel is intended to support application development on the company’s 400 MHz ARM926-based embedded microprocessor (MPU). The kit offers 480 Mbps EHCI-compliant high-speed USB with on-chip PHY, Ethernet, and SDIO.
The organic light emitting diode (OLED) display is becoming more and more popular, especially for mobile phones, media player and small entry level TVs. Contrary to a standard liquid crystal display, the OLED pixel is driven by a current source. To understand how and why the OLED power supply impacts the display picture quality, it is key to understand the OLED display technology and power supply requirements.
Toshiba will become a big player in optoelectronics—if their lighting division has its druthers. The company will release high-output LED light bulbs with a total flux equivalent to that of a 60 W incandescent lamp. The “natural white” type and the warm white type feature total fluxes of 810 lm and 600 lm, respectively.
