Embodiment 1
[0030] This embodiment provides a preparation method of a polarizing layer, such as figure 1 shown, including the following steps:
[0031] S01, applying a magnetic field to the substrate in the magnetotactic bacteria solution, so that the magnetotactic bacteria are arranged on the substrate;
[0032] S02. Introducing metal ions into the solution, so that the magnetotactic bacteria on the substrate absorb the metal ions and reduce the metal ions to simple metal;
[0033] S03. Removing part of the simple metal substance through a photolithography process, so that a metal line array with a polarization axis is formed on the substrate.
[0034] In this example, the metal polarizing layer is prepared by biotechnology. The preparation process is simple and the cost is low. The metal polarizing layer prepared by this method can reflect the unpassed light back to the backlight, change the polarization angle of the light and put it back into the polarizing layer to achieve Brighten ...
Embodiment 2
[0036] This embodiment provides a preparation method of a polarizing layer, such as Figure 1-4 shown, including the following steps:
[0037] S01. Applying a magnetic field to the substrate 1 in the magnetotactic bacteria 2 solution, so that the magnetotactic bacteria 2 are arranged and formed on the substrate 1. At this time, the surface of the substrate 1 is completely covered with the magnetotactic bacteria 2; wherein, Magnetotactic bacteria 2 (Magnetotactic bacterium) refers to bacteria that can perform directional movement under the action of an external magnetic field and form nano-magnetic particle magnetosomes in vivo.
[0038] Preferably, the concentration of the magnetotactic bacteria 2 in the solution of the magnetotactic bacteria 2 is 2-6 g / L.
[0039] That is to say, when the concentration of the magnetotactic bacteria 2 is 2-6 g / L, the adsorption speed of the substrate 1 to the magnetotactic bacteria 2 is faster and the adsorption rate is higher.

Abstract
The invention provides a preparation method of a polarization layer, a display base plate assembly and a display panel, and belongs to the technical field of display. The problems that the preparation of the existing metal type polaroid is difficult, and the existing polaroid cannot be made inside the display can be solved. Biotechnology is used for preparing the metal type polarization layer; magnetotactic bacteria on a substrate are used for adsorbing metal ions so that metallic elements are formed through reduction; then, the metallic elements form a metal line array with a polarization shaft; a metal type polarization layer is obtained. The method has the advantages that the preparation process is simple; the cost is low; unpassed light rays can be reflected back to a back light source through the prepared metal type polarization layer; after the polarization angle of the light rays are changed, the light rays are projected into the polarization layer again to realize the brightening. The display base plate assembly has the advantages that a color film base plate or array base plate can be directly used as a substrate; a built-in polarization layer is formed on the substrate by the method; the display base plate assembly is applicable to various display panels.
Description
technical field [0001] The invention belongs to the field of display technology, and in particular relates to a preparation method of a polarizing layer, a display substrate assembly, and a display panel. Background technique [0002] At present, the commonly used polarizing film is generally of the polymer dichroic type, which uses a polymer film such as polyvinyl alcohol (PVA, polyvinyl acetate) as a polarizing substrate, and absorbs dichroism such as iodine type or dye type. Sexual substances, so that iodide ions or dyes diffuse, penetrate into the inner layer of PVA, after alkali treatment, slightly heat-stretched PVA film is formed. [0003] The inventors found that there are at least the following problems in the prior art: the existing polarizing film has strong light leakage when used for large viewing angle display, and must be matched with a wide viewing angle film to achieve a high contrast effect; its weather resistance is poor and its mechanical properties are g...
