Single-colour molecules may shrink pixels

摘要

SHAPE-SHIFTING molecules that emit primary colours have been mixed to create a rainbow of hues for the first time. This morphing ensures that the colours are crisp and clear, potentially giving the molecules a future in high-resolution displays.Modern displays use bundles of micrometre-sized pixels of each primary colour - red, green and blue -to create a range of colours. But even such small pixels become noticeable on devices that are held close to the user's face, such as smartphones, computer screens and virtual reality headsets. To get round this, researchers are attempting to make pixels the size of a molecule.
