This foundational polariton particle breakthrough could lead to significant improvements in displays using an entirely novel approach compared to all previous ones. One significant difference is the ability of each polaritron to emit any wavelength, eliminating the need for separate red, green and blue (RGB) emitters intermixed in a grid. They are also able the achieve significantly greater energy levels, in other words, brightness.
