Ultra low power (ULP) RF specialist Nordic Semiconductor ASA announced that further to the Bluetooth SIG's official adoption of Bluetooth® low energy (as part of the latest Bluetooth Version 4.0 Core Specification), French multi-die system-in-package (SiP) design specialists, Insight SiP, has released the world's first drop-in single mode Bluetooth low energy SiP module.
Most LCD panel and set makers are focusing on development of LED (light emitting diode) backlight units for improved visual performance, thinner form factor, and lower power consumption. The key issue has been reducing cost, in absolute terms and relative to the conventional CCFL (cold cathode fluorescent) backlights. The newly-released DisplaySearch Quarterly LED & CCFL Backlight Cost Report, which is the only report to analyze and forecast the cost structure of CCFL and LED backlight costs, disclosed that the average cost of 40” edge LED backlight unit in Q1’10 is $118, and will fall to $100 by Q4’10 (see Figure 1). Cost reduction is driven by increasing production volumes, which affects LED and material costs, and by improvement in LED luminous intensity, which enables the use of fewer LED chips.
The ZigBee Alliance, a global ecosystem of companies creating wireless solutions for use in energy management, residential, commercial and consumer electronics applications, today announced it is now offering certification for ZigBee platforms designed to operate in the regional sub-1 GHz unlicensed frequencies. The move ensures original equipment manufacturers a source of tested platforms for use in sub-1 GHz applications.
