Problems solved by technology
[0004] In the current existing technology, the color filter of plasmonic display usually adopts sub-wavelength grating or metasurface structure. Among them, the pixel size of the metasurface structure is smaller, but the existing technology cannot realize narrow-band filtering covering red, green and blue. Especially in the blue light band, the energy loss is huge, and it is difficult to achieve full-color display

Description
technical field [0001] The invention relates to plasmon display technology, in particular to a reflective metasurface display device and a color image display method. Background technique [0002] Plasmon nanostructures and materials exhibit many special optical properties in light wave modulation, and have been applied in wavefront shaping, amplitude modulation, polarization state conversion, filtering and other fields. Plasmon nanostructures can be used to make ultra-thin color filters for projection display, three-dimensional display or holographic imaging to achieve ultra-high resolution imaging with pixel sizes on the order of microns or even nanometers. Today, optical imaging is becoming integrated and display devices are lightweight, showing huge potential application value. [0003] Traditional transmissive or reflective displays are large in size and weight. Each pixel consists of three sub-pixel units, which are respectively equipped with red, green, and blue colo...
