摘要:
A top emitting OLED is provided. The top emitting OLED comprises a substrate, a first electrode layer, an organic layer, and a second electrode layer. Wherein, the first electrode layer is formed on the substrate, the organic layer is formed on the first electrode layer, and the second electrode layer with a first refractive index is formed on the organic layer. Moreover, an anti-reflective layer with a second refractive index is formed on the second electrode layer. The first refractive index is different from the second refractive index, and the first thickness is matched and cooperated with the second thickness for reducing the reflectance of the OLED on visible light region.

A cathode structure for inverted OLEDs is provided, which comprise a substrate, a conductive electrode layer, an organic material layer, a dielectric layer, and a metal layer. Wherein, the conductive electrode layer is disposed over the substrate, the organic structure layer is disposed over the conductive electrode layer, the dielectric layer is disposed over the organic material layer, and the metal layer is disposed over the dielectric layer. Such cathode structure can function without using the metals of low work function and high chemical activity so as to benefit the manufacturing of organic light emitting devices and displays, and provide a more stable working conditions.
摘要:
A contact structure for organic luminescent devices is provided. The contact structure includes a first conductive layer, at least one pillar, an organic light-emitting layer, and a second conductive layer. The first conductive layer has a contact region. The at least one pillar is positioned on the first conductive layer in the contact region. The organic light-emitting layer covers the first conductive layer in the contact region and exposing a portion of the first conductive layer around the pillar in the contact region. The second conductive layer covers an exposed portion of the first conductive layer in the contact region. In one embodiment of the present invention, the pillar has a top surface and a bottom surface, and the width of the top surface is larger than that of the bottom surface.
