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.
The promise of the Internet of Things (IoT) is that devices, gadgets, and appliances we use every day will be able to communicate with one another. This potential is not limited to household items or smartphones, but also things we find in our yard and garden, as evidenced by a recent challenge from the element14 design community.
If you didn't realize that PowerPoint presentations are inherently hilarious, you have to see Don McMillan take one apart. McMillan -- aka the Technically Funny Comic -- worked for 10 years as an engineer before he switched to stand-up comedy.
The first Tacoma Narrows Bridge was a Washington State suspension bridge that opened in 1940 and spanned the Tacoma Narrows strait of Puget Sound between Tacoma and the Kitsap Peninsula. It opened to traffic on July 1, 1940, and dramatically collapsed into Puget Sound on November 7, just four months after it opened.
Noting that we now live in an era of “confusion and ill-conceived stuff,” Ammunition design studio founder Robert Brunner, speaking at Gigaom Roadmap, said that by adding connectivity to everything and its mother, we aren't necessarily doing ourselves any favors, with many ‘things’ just fine in their unconnected state.
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.
