(2020·黄冈市质量检测)One of the things that makes your smart phone so smart is that if you pull it out in the sun,it senses that and adjusts the screen brightness to compensate.But it's not a perfect solution.
“First of all,it's still not bright enough — you have to remember how respectable sunlight is,” said ShinTson Wu,a physicist at the University of Central Florida.The other problem,he says of the brightened screen,is that it kills the battery.So Wu and his colleagues have produced a batterysparing alternative: an antireflective screen coating,based on the eyes of moths.“Nature is so rich! We can learn a lot from nature.” The thing Wu and others have learned about moths' eyes,is that they're uneven,dotted with tiny projections.That uneven surface reduces the reflection of light off their eyes,thought to help the bugs escape predators(捕食动物),and see better in low light.So Wu and his team built a similar surface with tiny dimples (小凹),to cut down on glare.He says the coating could improve the readability of a screen by five to ten times,compared to a normal smart phone screen.The details are in the journal Optica.
The technology hasn't been commercialized yet,and that could take a few years,which gives researchers time to take advantage of another property of these surfaces — they're flexible,meaning the possibility of bendable displays.Combining that with the bendy batteries we reported on in a recent podcast (播客),the smart phones of the future could be set for a real transformation.
