Samsung's white-LED backlit display for 2008: 10k:1 contrast for your laptop


We're just talking LED-backlit LCD panels at the moment, but with any luck, they'll appear in your favorite laptop someday soon. Samsung's trio measure in at 18.4-inches (1,920 x 1,080), 16.0-inches (1,366 x 768), and a more traditional 15.4-inches (1,440 x 900). The latter boasts a White-LED backlighting for a whopping 10,000:1 contrast (at least), 300cd/m2 brightness, 45% color saturation, and power consumption of just 2 Watts or less when playing video. Expect the 16:9 pair to hit mass production in the first half of 2008 while the white-LED mofo should arrive before 2008 is through. Full specs after the break.

Researchers tout advances in development of pure white LEDs

Researchers at the Indian Institute of Science are making some fairly bold claims about their latest advance in the realm of white LEDs, boasting that they are now getting closer to the "Holy Grail of the illumination industry." That, they say, is a white LED that produces a pure white light suitable for everyday use (as opposed to the "warm white" LEDs used in pricey bulbs like the one seen here). The big advance here, it seems, is the development of the first LED based on a "new phosphor from semiconductor nanocrystals of cadmium sulfide mixed with manganese." While we're admittedly not entirely sure what all that is, the researchers claim that the result is an LED that produces a stable and constant shade of white light, which is "superior in overall performance" to previous white LEDs. They're apparently not fully satisfied with the results just yet though, and are reportedly working to boost the efficiency of the LEDs to make them more suitable for everyday applications.
