    摘要: Systems and methods for the design and fabrication of OLEDs, including high-performance large-area OLEDs, are provided. Variously described fabrication processes may be used to deposit and pattern bus lines and/or insulators using vapor deposition such as vacuum thermal evaporation (VTE) through a shadow mask, and may avoid multiple photolithography steps. Bus lines and/or insulators may be formed with a smooth profile and a gradual sidewall transition. Such smooth profiles may, for example, reduce the probability of electrical shorting at the bus lines. Other vapor deposition systems and methods may include, among others, sputter deposition, e-beam evaporation and chemical vapor deposition (CVD). A final profile of the bus line and/or insulator may substantially correspond to the profile as deposited. A single OILED devices may also be formed with relatively large dimension.

    摘要: Embodiments described herein may provide for devices comprising a digitized OLED light source (900) and/or methods of manufacturing such devices. In some embodiments, a first method may be provided. The first method may include the steps of depositing a first conductive layer (902) over a substrate (901), depositing a first organic layer (904) comprising electroluminescent material over the first conductive layer, and depositing a first patterned image layer (903) over some but not all of the first conductive layer. The first patterned image layer may locally alter the emissive properties of the first organic layer, and the shape of the first patterned image layer may be based on a non-uniform visual image. The first method may further comprise the step of depositing a second conductive layer (905) over the first organic layer.

    摘要: A light emitting device with high light emission uniformity is disclosed. The device contains a first electrically conductive layer having a positive polarity and an electrically conductive uniformity enhancement layer in contact with the first electrically conductive layer. The device also contains a second electrically conductive layer having a negative polarity and a light-emitting structure situated between the first and the second electrically conductive layers. The light-emitting structure contains an organic material in direct contact with the second electrically conductive layer. The uniformity enhancement layer transmits essentially all wavelengths of light emitted by the light-emitting structure. Compared to devices lacking a uniformity enhancement layer, the device exhibits higher spatial uniformity in luminance and in color spectrum.
