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.
Robots that walk have come a long way from simple barebones walking machines or pairs of legs without an upper body and head. Much of the research these days focuses on making more humanoid robots. But they are not all created equal.
The IEEE Computer Society has named the top 10 trends for 2014. You can expect the convergence of cloud computing and mobile devices, advances in health care data and devices, as well as privacy issues in social media to make the headlines. And 3D printing came out of nowhere to make a big splash.
For industrial control applications, or even a simple assembly line, that machine can go almost 24/7 without a break. But what happens when the task is a little more complex? That’s where the “smart” machine would come in. The smart machine is one that has some simple (or complex in some cases) processing capability to be able to adapt to changing conditions. Such machines are suited for a host of applications, including automotive, aerospace, defense, medical, computers and electronics, telecommunications, consumer goods, and so on. This discussion will examine what’s possible with smart machines, and what tradeoffs need to be made to implement such a solution.
