System and method for a flexible display encapsulation

摘要

Provided is an OLED device that is rollable and has a rollable protective covering to protect the OLED when rolled. The rollable protective covering may include a single layer barrier and a plastic lid. The single layer barrier may provide permeation protection to the OLED in the OLED device. The protective covering provides mechanical protection to the OLED device when rolled. The protective covering and the OLED may be fabricated separately and assembled afterwards.

主权项

1. A rollable device, comprising:
a rollable OLED; a rollable plastic lid laminated on to the rollable OLED, the rollable plastic lid comprising: a plastic lid layer; a single layer barrier disposed on a first side of the plastic lid layer, the single layer barrier to prevent at least one of moisture and oxygen from contacting the OLED; and a rollable hardcoat disposed on a second side of the plastic lid layer opposite to the first side to provide mechanical protection, wherein the single layer barrier is disposed between the rollable OLED and the the plastic lid layer; and wherein the rollable device has a radius of curvature that is less than 30 cm and is capable of being curved to overlap itself more than one complete revolution.
