Embodiment Construction

[0050] Exemplary embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. Although exemplary embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure may be embodied in various forms and should not be limited by the embodiments set forth herein. Rather, these embodiments are provided for more thorough understanding of the present disclosure and to fully convey the scope of the present disclosure to those skilled in the art.

[0051] In order to better explain the beneficial effects brought by the embodiments of the present invention, the applicant believes that the technical problems in the existing display screen should be introduced first, that is, the moiré and Newton rings mentioned in the background art.

[0052] Moiré refers to the high-frequency interference fringes that appear in the photosensitive element of the display screen. Specifically, moi...

Abstract

An embodiment of the invention provides a display panel. The display panel comprises a first display panel and a second display panel arranged above the first display panel, and further comprises a plurality of optical anisotropic array structures; and the array structures are positioned between the first display panel and the second display panel, and are used for supporting the first display panel and the second display panel. The embodiment of the invention further discloses a manufacturing method and a display device of the display panel. The array structures are arranged between the firstdisplay panel and the second display panel of the embodiment of the invention, and have optical anisotropy, a dispersion curve of light wave which spreads in the array structures becomes band-shapedstructures, photonic band gaps which are similar to semiconductor band gaps will exist among the band-shaped structures, frequency drops in photons in the photonic band gaps and cannot spread in the array structures, then interference ripples are scattered, moire is eliminated, and the display effect of the display panel is improved.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a display panel, a manufacturing method thereof, and a display device. Background technique [0002] With the development of science and technology, people put forward higher requirements on the display effect of a liquid crystal display (Liquid Crystal Display; LCD). More and more high-end liquid crystal displays adopt a two-layer panel stacking structure to improve contrast and other characteristics. However, in the actual display imaging effect, the upper and lower panels have similar patterns such as grid stripes, which are prone to moiré and affect the visual experience. Moiré is a visual phenomenon of interference fringes produced by the superposition of two equal-amplitude sine waves with similar frequencies on objects with a certain interval. [0003] In addition, the applicant also found that in the stacked structure of two-layer panels, the upper and lower panels are...
