Problems solved by technology

[0004] For monochrome devices, organic electroluminescent display devices using polymers can be fabricated simply by spin-coating processes and require lower driving voltages than devices using small molecules, however, organic electroluminescent display devices using polymers Display devices have the disadvantages of reduced efficiency and reduced lifetime
In addition, red, green, and blue polymers must be patterned to fabricate full-color devices, which can degrade light-emitting properties such as efficiency and lifetime when patterned using inkjet techniques or laser-induced thermal imaging processes

Embodiment Construction

[0023] Hereinafter, the present invention will be described in more detail.

[0024] Figure 1A is a view of the transfer mechanism when using a laser to transfer-pattern an organic emissive layer for an organic electroluminescent display device.

[0025] As shown in Figure 1, the mechanism of using laser to transfer-pattern the organic layer needs to separate the organic layer S2 adhered to the substrate S1 from the substrate S1 by laser, and then transfer the organic layer S2 to the substrate S3, so that the organic Layer S2 is separated from the portion not irradiated by the laser light.

[0026] Factors determining the transfer characteristics include a first adhesion force W12 between the substrate S1 and the layer S2, an interlayer adhesion force W22 between the layers, and a second adhesion force W23 between the layer S2 and the substrate S3.

[0027] By using the surface tensions γ1, γ2, and γ3 and the interfacial tensions γ12 and γ23 of the respective layers to repre...

Abstract

Provided is a donor substrate for a full-color organic electroluminescence display device, comprising: a base film; a light-to-heat conversion layer formed on the base film; and a light-to-heat conversion layer formed on the light-to-heat conversion layer transfer layer. The transfer layer is an organic layer comprising a patterned organic electroluminescent material. Therefore, a high-definition and large-sized organic electroluminescence display device can be manufactured in which misalignment does not occur when the emission layer is formed. The donor substrate and a full-color organic electroluminescent display device comprising the donor substrate are manufactured by the method according to the invention.

Description

[0001] This application claims the Serial No. 2003-84243 filed with the Korean Intellectual Property Office on November 25, 2003 and entitled "Donor film for full-color organic electroluminescent Full-color organic electroluminescent display device of film ", the entire content of which is hereby incorporated by reference. technical field [0002] The invention relates to a donor substrate for a full-color organic electroluminescent display device, a manufacturing method thereof, and a full-color organic electroluminescent display device using the donor substrate. More precisely, the present invention relates to a donor substrate for a full-color organic electroluminescent display device and a method of manufacturing the same, and a full-color organic electroluminescent display device using the donor substrate, wherein the formation of a full-color organic electroluminescent display device is The transfer donor substrate used in the emissive layer of an electroluminescent disp...
