Estimating the term…
Improved seal for flexible organic light emitting displays are provided. For the purpose of the present invention it is realisd that a homogenous seal cannot provide for the combination of resuired robusness and required impermeability, which are essential for the life time of the display. Therefore, a seal comprising an inner seal portion and an outer seal portion is proposed. The outer seal portion is flexible as compared to the inner seal portion and the inner seal portion is impermeable as compared to the outer seal portion and being deposited between the outer seal portion and the display element.
A flexible organic light emitting display element, comprising a flexible back plate substrate, a flexible cover substrate, a seal, an active display element which is deposited on said flexible back plate substrate wherein said back plate and cover substrates are joined together by said seal so as to encapsulate said active display element, and wherein said seal comprises an inner seal portion and an outer seal portion, the outer seal portion being flexible as compared to the inner seal portion and the inner seal portion being impermeable as compared to the outer seal portion and being deposited between the outer seal portion and the display element.
