Abstract

The embodiment of the invention discloses a reflectivity adjusting structure, a manufacturing method and a display panel. The reflectivity adjusting structure comprises an elastic dielectric layer and a plurality of embedded units, and each embedded unit comprises a metal layer, and the multiple embedded units are arranged in the elastic dielectric layer in an array mode, wherein the elastic dielectric layer is deformed, and the gap between the embeddable units is changed. The design of the reflectivity adjusting structure does not depend on optical polarization, the design condition requirement is low, the polarization of the design structure is not sensitive, and the reflectivity adjusting structure can be directly used for the natural light environment; and the metal layer and the elastic dielectric layer which form the structure are easy to process and can be well compatible with the existing manufacturing process.

Description

technical field [0001] The invention relates to the technical field of optical devices, in particular to a reflectivity adjustment structure, a manufacturing method and a display panel. Background technique [0002] Asymmetric Light Transmission (ALT) refers to the difference in transmittance measured when light is incident on both sides of the device. It has potential applications in the development of next-generation all-optical computing processing equipment and systems, as well as in automobiles and other fields. The schemes to realize asymmetric transmission devices of light are mainly based on optical non-reciprocity methods, such as magneto-optic effect, nonlinear optics, indirect interband photon transition and photoacoustic effect, etc. Optical nonreciprocity is an ideal solution because it enables the device to transmit any optical mode in one direction and filter the direction-parallel optical mode with a polarizer in the other direction. However, the above sche...
