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.
Advertised as the "Most Powerful Tablet Under $100," the Kindle Fire HD 6 was too tempting for the team at iFixit to pass up. Join us to find out if inexpensive means cheap, irreparable, or just down right economical. It's teardown time!
The increased adoption of wireless technology for mission-critical applications has revved up the global market for dynamic electronic general purpose (GP) test equipment. As the link between cloud networks and devices -- smartphones, tablets, and notebooks -- results in more complex devices under test, the demand for radio frequency test equipment is starting to intensify.
Much of the research on lithium-ion batteries is focused on how to make the batteries charge more quickly and last longer than they currently do, work that would significantly improve the experience of mobile device users, as well EV and hybrid car drivers. Researchers in Singapore have come up with what seems like the best solution so far -- a battery that can recharge itself in mere minutes and has a potential lifespan of 20 years.
Some humanoid walking robots are also good at running, balancing, and coordinated movements in group settings. Several of our sports robots have won regional or worldwide acclaim in the RoboCup soccer World Cup, or FIRST Robotics competitions. Others include the world's first hockey-playing robot and a trash-talking Scrabble player.
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.
