1. Scientists have created the world's smallest pixels, by trapping particles of light under tiny rocks of gold, which could be used for new types of large-scale flexible displays.
2. The pixels could enable a host of new application possibilities such as building-sized display screens, architecture which can switch off solar heat load, active camouflage clothing and coatings, as well as tiny indicators.
3. The team of scientists, made the pixels by coating vats of golden grains with an active polymer called polyaniline and then spraying them onto flexible mirror-coated plastic, to drive down production cost.
4. The pixels are million times smaller than typical Smartphone pixels. They can be seen in bright sunlight and because they do not need constant power to keep their set colour, have energy performance that makes large areas feasible and sustainable.
