Embodiment Construction

[0049] In order to facilitate the understanding of the present invention, the present invention will be described more fully below with reference to the associated drawings. Preferred embodiments of the invention are shown in the accompanying drawings. However, the present invention can be embodied in many different forms and is not limited to the embodiments described herein. On the contrary, these embodiments are provided to make the understanding of the disclosure of the present invention more thorough and comprehensive.

[0050] It should be noted that when an element is referred to as being “disposed on” another element, it may be directly on the other element or there may also be an intervening element. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or intervening elements may also be present.

[0051] Unless otherwise defined, all technical and scientific terms used herein have the same meaning...

Abstract

The invention relates to a structural color substrate, an optical element, a manufacturing method thereof and a display device. The structural color substrate comprises a substrate, a plurality of pixel wall structures and a plurality of nano protrusions, the plurality of pixel wall structures are arranged on the substrate in parallel, and a pixel band is defined by two adjacent pixel wall structures; a plurality of nanometer protrusions are independently arranged in each pixel band, and the nanometer protrusions in the pixel bands are arranged in an array mode. The pixel bands are defined through the pixel wall structures, a plurality of nano protrusions are arranged in each pixel band, the plurality of nano protrusions in each pixel band are periodically arranged, and the hue of a certain wavelength can be selectively enhanced by adjusting the interval period of the nano protrusions, so that the hue of a diffraction color is adjusted. As the nanometer protrusions are of a physical structure, the nanometer protrusions are stable and reliable, and the problem that the colloidal particle spacing of colloidal crystal particles in the traditional colloidal ink is difficult to controlis avoided.

Description

technical field [0001] The invention relates to the technical field of structural color display, in particular to a structural color substrate, an optical element, a manufacturing method thereof, and a display device. Background technique [0002] The usual color reproduction process requires the use of inks, pigments, dyes and other materials. This color reproduction process relies on pigment molecules selectively absorbing, reflecting and transmitting wavelengths in a specific visible light range under external light to show different color sensations. , these colors are pigmented colors. However, the color of such pigments will continuously degrade with time, environment and other external conditions, and it is difficult to exist for a long time, and usually such pigments are biologically toxic and have poor biological and environmental compatibility. [0003] Compared with pigment coloring, structural color, which is closely related to microstructure, is a completely di...
