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.
There is currently much discussion around the term "platform," which may be preceded by the adjectives "mobile," "wearable," "medical," "healthcare," etc. However, regardless of the platform being discussed, they usually have one key aspect in common: They tend to be wireless. So, why is this one aspect so fairly universal? The answer is convenience.
Everyone has a MEMS story. For most of us it’s probably the airbag that saved our lives or the life of a loved one. Perhaps it’s the tire pressure sensor that alerted us about deflation before we were stranded alone on a dark muddy road.
Bioimimicry is not merely a helpful design tool -- it also encourages designers to think not only about how to solve design problems by imitating nature, but how to make the products, materials, and systems they design more ecologically sound and nature-friendly.
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.
