摘要:
Various embodiments set forth light emission display elements, and display devices that include such display elements. In some embodiments, a display element includes an electroluminescent light source and a pair of reflective elements that form a resonant cavity for a particular range of wavelengths and/or a particular polarization of light. One or both of the reflective elements can include meta-reflectors, such as anisotropic meta-reflectors or chiral meta-reflectors. An optional waveplate can be placed between the reflective elements to adjust the polarization state of light emitted by the display element.
