摘要： Light extraction blocks, and OLED lighting panels using light extraction blocks, are described, in which the light extraction blocks include various curved shapes that provide improved light extraction properties compared to parallel emissive surface, and a thinner form factor and better light extraction than a hemisphere. Lighting systems described herein may include a light source with an OLED panel. A light extraction block with a three-dimensional light emitting surface may be optically coupled to the light source. The three-dimensional light emitting surface of the block may includes a substantially curved surface, with further characteristics related to the curvature of the surface at given points. A first radius of curvature corresponding to a maximum principal curvature k1 at a point p on the substantially curved surface may be greater than a maximum height of the light extraction block. A maximum height of the light extraction block may be less than 50% of a maximum width of the light extraction block. Surfaces with cross sections made up of line segments and inflection points may also be fit to approximated curves for calculating the radius of curvature.

摘要： Charge transport enhancement layers and structures are provided that may improve the performance of organic devices, specifically organic light emitting devices. A charge transport enhancement layer may include a layer or an inorganic material, metal oxide, halide, and/or alkali disposed between two organic layers, and separated from the cathode by an intervening organic layer. One or more CTELs may be used, such as in an alternating stack of organic and CTEL layers. Surprisingly, it has been found that the use of one or more CTELs arranged in a stack with intervening organic layers may improve the performance of the device even where the layer is not directly adjacent to the cathode.

摘要： Systems, and methods for the design and fabrication of OLEDs, including large-area OLEDs with metal bus lines, are provided. For a given panel area dimension, target luminous emittance, OLED device structure and efficiency (as given by the JVL characteristics of an equivalent small area pixel), and electrical resistivity and thickness of the bus line material and electrode onto which the bus lines are disposed, a bus line pattern may be designed such that Fill Factor (FF), Luminance Uniformity (U) and Power Loss (PL) may be optimized. One general design objective may be to maximize FF, maximize U and minimize PL. Another approach may be, for example, to define minimum criteria for U and a maximum criteria for PL, and then to optimize the bus line layout to maximize FF. OLED panels including bus lines with different resistances (R1) along a length of the bus line are also described.

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： 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.
