1. A display screen, comprising an organic light emitting diode (OLED) device:
- wherein the OLED device comprises an OLED device encapsulating structure, which is configured to encapsulate an OLED;
wherein the OLED device encapsulating structure comprises;
a substrate;
a barrier layer formed on the substrate;
a surface active layer disposed on the barrier layer;
a buffer layer stacked on the surface active layer, an orthogonal projection of the buffer layer onto the barrier layer coinciding with that of the surface active layer onto the barrier layer; and
a composite layer stacked on the buffer layer;
wherein the surface active layer is sandwiched between and in direct contact with the barrier layer and the buffer layer and the surface active layer is a material that creates a hydrogen bond with a material of the buffer layer to enhance bonding therebetween.

Abstract
A display screen includes an OLED device encapsulating structure that encapsulates an OLED. The OLED device encapsulating structure includes a substrate, a barrier layer formed on the substrate, a surface active layer disposed on the barrier layer, and a buffer layer stacked on the surface active layer. An orthogonal projection of the buffer layer on the barrier layer is coincident with that of the surface active layer on the barrier layer. A composite layer may be further stacked on the buffer.
