OSRAM Opto Semiconductors' RGB Multi ChipLEDs are used in the FormoLight display. Their compact size
permits a special image format in LED video displays ranging in size from small
to large screens. In this display, for interior use, the LEDs are not used as
backlighting light sources that are hidden from viewers such as in LCDs, but in
this application the LEDs are clearly visible on the surface of the display. They
remain undetected by viewers because of the Multi ChipLEDs small size of 1.6 x
1.6 mm and 0.9 mm thick, and virtually invisible through the black LED housing.
Multi ChipLEDs produce a
homogenous image from virtually any viewing angle. This homogeneity is based on
two principles. The LEDs can be packed very closely together because of their
compact size - the distance between pixels can be as little as 2 mm. Also, the special casting material ensures a
perfect color mix. The LEDs contain three chips (red, green, blue) manufactured
using OSRAM's Thinfilm or ThinGaN technology, each of which can be controlled
separately. The color impression is constant across the entire viewing angle
and remains brilliant even when viewed from the side. Thanks to the LEDs' sharp
contrasts and high output, this high image quality is maintained even in high
ambient light environments. The LEDs are characterized by low power consumption
and long life.
Samsung's Galaxy line of smartphones used to fare quite well in the repairability department, but last year's flagship S5 model took a tumble, scoring a meh-inducing 5/10. Will the newly redesigned S6 lead us back into star-studded territory, or will we sink further into the depths of a repairability black hole?
In 2003, the world contained just over 500 million Internet-connected devices. By 2010, this figure had risen to 12.5 billion connected objects, almost six devices per individual with access to the Internet. Now, as we move into 2015, the number of connected 'things' is expected to reach 25 billion, ultimately edging toward 50 billion by the end of the decade.
NASA engineer Brian Trease studied abroad in Japan as a high school student and used to fold fast-food wrappers into cranes using origami techniques he learned in library books. Inspired by this, he began to imagine that origami could be applied to building spacecraft components, particularly solar panels that could one day send solar power from space to be used on earth.
Focus on Fundamentals consists of 45-minute on-line classes that cover a host of technologies. You learn without leaving the comfort of your desk. All classes are taught by subject-matter experts and all are archived. So if you can't attend live, attend at your convenience.
