A photonic crystal display refers to the use of photonic crystals in next-generation reflective display applications. A photonic crystal is an optical nanostructure that reflects motion photons in the form of a colorful band. This band of colors can be controlled by applying current and voltage. Photonic crystal displays are high performance and enhanced display quality.
A photonic crystal display involves the process of tuning the color band exhibited by a photonic crystal. All spectral colors in the visible range are reflected by this material, hence it does not involve the use of large amounts of crystal in a single display screen. The colors produced through this process are more vibrant and of a wider range than ordinary RGB. Other advantages of using photonic crystal displays in a device are lower power consumption, high reflectivity and high pixels-per-inch resolution.
