Problems solved by technology

However, where multiple barrier layers are provided in an attempt to provide sufficient barrier protection against water vapor transmission, the addition of multiple barrier layers to a display / device increases the overall thickness of the display / device and reduces its flexibility
Furthermore, because typically multiple barrier layers are not dynamically flexible, after repeated bending they tend to form cracks which can destroy the integrity of the barrier layers

Embodiment Construction

[0021] These figures schematically illustrate a device 100 comprising a first layer 101 and a second layer 102 covering the first layer. These layers may be disposed on the surface 103 of the substrate 104 to provide a barrier coating for the surface. In various examples, the device provides a protective barrier coating that attempts to prevent the ingress / passage of contaminants such as moisture, particles and oil, among others, through the surface / substrate.

[0022] The first layer comprises a plurality of two-dimensional platelets 101' of a first material. The term "two-dimensional platelets of the first material" is a generic term that includes, for example, having a platelet morphology—that is, having a thickness of only a few nanometers (e.g., less than 1, 5, or 10 nm) but having a thickness of several microns (e.g., 0.1-10 [mu]m or 0.1-100 [mu]m in the lateral extent - materials; two-dimensional sheet-like materials, such as graphene oxide flakes; or nanoplatelets.

Abstract

The invention relates to a barrier coating (100) for a surface (103) of a substrate (104) comprising a plurality of two-dimensional platelets (101) of a first material; and at least another layer (102) covering the first layer.

Description

technical field [0001] Examples of the present disclosure relate to apparatus and methods for providing barrier coatings. In particular, without prejudice to the foregoing, certain examples relate to protective barrier coatings for organic light emitting diode displays. Background technique [0002] Electronic displays are susceptible to damage due to the ingress of pollutants such as moisture from the surrounding environment. For example, organic light emitting diode (OLED) displays are typically fabricated on polymer substrates, due to which OLED displays are highly susceptible to damage from water and oxygen. Commonly used polymeric substrates have poor intrinsic barrier properties and poor surface quality compared to glass substrates. OLED displays and their polymer substrates can also be flexible, which presents additional difficulties. The provision of a single barrier layer will not provide an adequate level of barrier protection. However, where multiple barrier l...
