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.
摘要翻译：公开了一种具有高发光均匀性的发光器件。该器件包含具有正极性的第一导电层和与第一导电层接触的导电均匀性增强层。该器件还包含具有负极性的第二导电层和位于第一和第二导电层之间的发光结构。发光结构包含与第二导电层直接接触的有机材料。均匀性增强层基本上透射由发光结构发射的所有波长的光。与缺乏均匀性增强层的器件相比，该器件在亮度和色谱中表现出更高的空间均匀性。
