Embodiment Construction

[0033] In order to make the above objects, features and advantages of the present invention more comprehensible, specific implementations of the present invention will be described in detail below in conjunction with the accompanying drawings. In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present invention. However, the present invention can be implemented in many other ways different from those described here, and those skilled in the art can make similar improvements without departing from the connotation of the present invention, so the present invention is not limited by the specific embodiments disclosed below.

[0034] It should be noted that when an element is referred to as being “disposed on” another element, it may be directly on the other element or there may also be an intervening element. When an element is referred to as being "connected to" another element, it can be directly connected t...

Abstract

The invention relates to a polarizer, a preparation method thereof, and a display panel, wherein the polarizer comprises: a glass substrate; a glass encapsulation layer, wherein the glass encapsulation layer and the glass substrate form a closed cavity; Inside the closed cavity. The above polarizer adopts a glass substrate and a glass encapsulation layer to form a closed cavity to wrap the polarizing structure, so that the polarizing structure cannot be in contact with water vapor, which can prevent water vapor from intruding into the polarizing structure from the side, and improve the reliability of the polarizing structure.

Description

technical field [0001] The invention relates to the display field, in particular to a polarizer, a preparation method thereof, and a display panel. Background technique [0002] Currently, OLED (Organic Light-Emitting Diode) display panels are gradually developing into mainstream displays. At present, glass substrates are widely used in OLED display panels, and light-emitting structures are arranged on the glass substrates. Because devices produced with glass substrates have glare, grid effects formed by densely distributed pixels, and contrast effects, etc., a layer of polarizer will be pasted on the light-emitting surface glass to eliminate these defects. Generally, the polarizer includes a PVA (polyvinyl alcohol, vinylalcohol polymer, polyvinyl alcohol) layer, and the PVA layer is dyed with iodine to achieve a polarizing effect. [0003] The inventor found that when implementing the traditional technology, water and oxygen would permeate into the inside of the polarizer...
