Benefits of technology
The method enhances light utilization and polarization efficiency by expanding the wavelength range of light absorption and increasing the number of polarization layers, thereby improving the performance of dye polarizers without the need for additional protective layers, allowing for thinner and more durable display panels.
Problems solved by technology
The state-of-the-art dye polarizers have a relatively narrow absorption wavelength of light, leading to lowered utilization of light and also low degree of polarization.

Abstract
A fabrication method of a dye polarizer and a display panel are provided. The fabrication method includes: dissolving a dye mixture and a reactive monomer in a solvent to form a polarization film solution, in which the dye mixture is formed by mixing multiple dichroic dyes and the dye mixture functions to absorb visible light of all wave band; coating the polarization film solution one a base, followed by alignment, to allow the reactive monomer to cure on the base; and repeating the step of forming the dye polarization film for n times to form a dye polarizer including n+1 stacked layers of the dye polarization, where n is a nature number greater than or equal to 2. The display panel includes the dye polarizer that is formed with the fabrication method described above.
Description
CROSS REFERENCE TO RELATED APPLICATIONS[0001]This is a divisional application of co-pending U.S. patent application Ser. No. 15 / 776,367, filed on May 15, 2018, which is a national stage of PCT Application No. PCT / CN2018 / 074690, filed on Jan. 31, 2018, claiming foreign priority of Chinese Patent Application No. 201710530079.2, filed on Jun. 30, 2017.BACKGROUND OF THE INVENTION1. Field of the Invention[0002]This application relates to the technical field of display panels, and more particularly to a fabrication method for a dye polarized and a display panel.2. The Related Arts[0003]A polarizer is a very important part of a liquid crystal panel and determines, to quite an extent, key characteristic indexes of the liquid crystal panel, such as contrast, transmission rate, brightness, and thickness. Among the polarizers, dye polarizers are a kind of important polarizers. The state-of-the-art dye polarizers have a relatively narrow absorption wavelength of light, leading to lowered utiliz...
