Problems solved by technology

However, the production of imprint templates used in NIL technology is relatively complicated and expensive, and the preparation of large-size imprint templates is still an unsolved process difficulty
Polarizing films can also be formed on glass substrates using general exposure equipment. However, taking the 8th generation of exposure equipment as an example, manufacturing a 55-inch panel requires several exposures. There are subtle gaps between each exposure, and the complete image cannot be displayed.

Abstract

The invention discloses a preparation method of a polarizing film, a display substrate and a display device. An aluminum oxide nanotube layer of which the extending direction is parallel to a lining substrate is formed on the lining substrate; all aluminum oxide nanotubes in the aluminum oxide nanotube layer are filled with first metal, so that the aluminum oxide nanotube layer formed on the lining substrate has the polarized property. According to the preparation method of the polarizing film, the display substrate and the display device, the polarizing film is prepared on the lining substrate in situ, and a polaroid does not need to be attached to the lining substrate; in addition, a ripe electrochemical technology is adopted, and compared with an existing method for preparing the polarizing film through an NIL technique or an exposure technology, the preparation method has the advantages that no complex technology is needed, the cost is low, and the preparation method is suitable for large-size production.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a preparation method of a polarizing film, a display substrate and a display device. Background technique [0002] Polarizers are widely used in the field of flat panel displays. For a Thin Film Transistor Liquid Crystal Display (TFT-LCD for short), usually a polarizer is pasted on a glass substrate to produce a polarizing effect. In order to prepare polarizers in situ on glass substrates to replace traditional polarizers, thereby saving the cost of purchasing and attaching traditional polarizers. Practitioners have tried different approaches. In the prior art, nano-imprint lithography (Nano-imprint Lithography, NIL for short) or exposure equipment can be used to form a polarizing film on a glass substrate. [0003] NIL technology is to form a pattern on a glass substrate with an embossing machine that imprints a pattern. The specific process is to apply pressure with an emb...
