To make liquid crystal displays brighter, more energy-efficient, and easier-to-see, this display architecture uses phosphor materials instead of filters. The basic idea is to turn what is a transmissive or transflective display into an emissive one—that is to use an active or passive matrix LCD display to activate a photoluminescent display screen that offers better color purity, a wider viewing angle, and reduced power consumption.
This new display architecture is available for license and is targeted at applications where improved display visibility and power efficiency are important.
Two approaches can be used to backlight such a display: near-ultraviolet that stimulates an emissive screen composed of green, red, and blue phosphors; and monochrome (blue) that stimulates green and red phosphors only. While the near-UV allows using standard phosphors, it comes at the expense of operating life. The monochrome blue approach overcomes the UV degradation issue, but requires more expensive red and green phosphor materials.
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.
