Abstract

The invention provides a method for preparing an ultra-thin polarizer through a self-assembly method, the ultra-thin polarizer and a display panel. The method comprises the following steps that characteristic information of a nanoparticle array which can realize the polarizing function is simulated by simulation software, and the characteristic information comprises shape information, dimension information, particle arrangement information and the array period of nanoparticles; structural parameters of a groove array are calculated according to the characteristic information, and the groove array with the specified shape is formed on a base plate through the structural parameters; colloid of the nanoparticles is added dropwise on the base plate provided with the groove array, and thus a patterning nanoparticle array is formed; sticky glue makes contact with the nanoparticles in the groove, the sticky glue and the nanoparticles are combined, and then the sticky glue is cured to form a sticky glue thin film; and the sticky glue thin film attached with the nanoparticle array is separated from the base plate provided with the groove array, a sticky glue layer is attached to the other side of the sticky glue thin film attached with the nanoparticle array, and thus a closed nanoparticle array is formed.

Description

technical field [0001] The invention relates to the field of optical devices, in particular to a method for preparing an ultra-thin polarizer by a self-assembly method and the ultra-thin polarizer. Background technique [0002] With the development of science and technology and the improvement of people's requirements for products, display devices are no longer limited to flat displays, and curved displays are pursuing higher-end bendable and fully flexible technology. The fully flexible technology requires that the thickness of each component of the display screen be further reduced, including the important components (polarizers) in the display screen. At present, the polarizers commonly used in OLED devices are mainly stretched PVA films, and the thickness is on the order of tens of microns, which limits the use of OLED devices for dynamic flexible displays. In order to realize the dynamic flexible display of OLED devices, it is necessary to introduce thinner polarizers ...
