Abstract

The invention relates to an optical thin film, and particularly relates to a flexible transparent barrier film and a preparation method thereof, so as to solve the problems that low transmittance is likely to happen to a composite barrier film and barrier performance generated after rolling drops. The barrier film comprises a flexible substrate; a barrier layer is arranged on the flexible substrate; a protection layer is arranged on the barrier layer; the flexible substrate is a transparent thin film; the barrier layer comprises at least two organic layers and at least two inorganic layers; the organic layers and the inorganic layers are arranged alternately; and the flexible substrate is connected with the organic layers in the barrier layer. The flexible transparent barrier film has good transmittance, and the barrier performance is still excellent after multiple times of rolling.

Description

technical field [0001] The invention relates to an optical film, in particular to a flexible transparent barrier film and a preparation method thereof. Background technique [0002] With the advent of the digital age, liquid crystal displays (LCDs) have become the most ubiquitous display technology today. In recent years, the excellent performance of quantum dots and organic light-emitting diodes in terms of optical performance, for example, the introduction of quantum dots will greatly improve the color gamut, which has attracted widespread attention in related industries such as displays. Organic light-emitting diodes (OLEDs) and quantum dots are very sensitive to oxygen and moisture in the ambient atmosphere. The most direct and effective way to broaden the application of such materials is to block the contact of materials with water or oxygen. The traditional encapsulation process adopts the method of encapsulating the glass cover and attaching a desiccant inside it. Th...
