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.

Their unusual “Enclosed Open Frame” Design has been laid out for fully automatic manufacturing processes. Temperatures of +245°C, as are usual during vapor soldering, and are handled without problems.
IBM has announced a really fast power transistor. Of course power is a relative thing. At the frequencies involved power is a relative thing. I'd say they would be doing good if they could get between 1 and 10 watts out of the device.

Much has been written about the efficiency of Class D amplifiers, with figures of 90 percent or greater being routinely quoted. Such numbers might seem to suggest that the efficiency problem of audio amplifiers has been well-solved by conventional Class D. However, a closer look shows that this is far from the truth, with these amplifiers frequently seeing only single-digit percentage efficiencies, in real product usage conditions.
