In a recent breakthrough, scientists have developed a new type of light emitting array which can produce a wide range of colors in an incredibly efficient manner. Using a compressive sensing technique, the array is able to produce up to 10,000 different color combinations with only three light sources. This means that the array can produce an incredibly diverse range of colors with only a fraction of the energy normally needed. The potential applications are vast, from medical imaging to smart lighting. This technology could revolutionize the way we think about lighting and could have a huge impact on our daily lives.
