Organic light emitting display providing ultraviolet ray protection and method of manufacturing same
View Patent ↗An organic light emitting display including an ultraviolet protecting layer and a method of manufacturing the same include a lower substrate; an ultraviolet hardening adhesive formed on the lower substrate; a driving unit and a light emitting unit deposited on the lower substrate and surrounded by the ultraviolet hardening adhesive; an encapsulation layer covering the driving unit and light emitting unit and preventing moisture and oxygen penetration from an outside; an upper substrate arranged on the encapsulation layer facing the lower substrate and fixed by the ultraviolet hardening adhesive; and an ultraviolet ray blocking film formed in a region to block the driving unit and the light emitting unit from being irradiated by UV rays radiated to harden the ultraviolet hardening adhesive. The ultraviolet ray blocking film is disposed in the encapsulation layer or on the upper substrate to protect the driving unit and light emitting unit from ultraviolet rays.
1. An organic light emitting display comprising:
a lower substrate;
an ultraviolet hardening adhesive formed on the lower substrate;
a driving unit and a light emitting unit deposited on the lower substrate and surrounded by the ultraviolet hardening adhesive;
an encapsulation layer covering the driving unit and light emitting unit and preventing moisture and oxygen penetration from an outside;
an upper substrate arranged on the encapsulation layer facing the lower substrate and fixed by the ultraviolet hardening adhesive; and
an ultraviolet ray blocking film formed in a region to block the driving unit and the light emitting unit from being irradiated by UV rays radiated to harden the ultraviolet hardening adhesive, wherein the encapsulation layer has a multi-layered structure comprising inorganic layers and organic layers; and the ultraviolet ray blocking film is disposed between the multi-layered structure of the encapsulation layer.
2. The organic light emitting display of claim 1 , wherein the upper substrate is made of glass, plastic or metal.
3. The organic light emitting display of claim 1 , wherein the ultraviolet ray blocking film is composed of at least one ultraviolet-absorbing agent selected from the group consisting of benzotriazoles, benzophenones, salicylic acids and cyano acrylates.
4. The organic light emitting display of claim 1 , wherein the ultraviolet hardening adhesive is formed in a non-display area and the driving unit and the light emitting unit are formed in a display area.
5. The organic light emitting display of claim 4 , wherein the ultraviolet ray blocking film is aligned with the display area.
