Abstract:
1. A light emitting OLED apparatus comprising a microcavity OLED device having a broad-band light emitting organic EL element and configured to have angular-dependent narrow-band light emission, and a patterned light-integrating element comprising a light-integrating portion and a non-light-integrating portion each provided over a portion of a light emitting region of the microcavity device, wherein the light-integrating portion of the light-integrating element integrates the angular-dependent narrow-band emission from different angles from the microcavity OLED device to form an integrated light emission with decreased angular dependence in accordance with the pattern of the light-integrating portion of the light-integrating element, and the apparatus maintains relatively angular-dependent emission for light emitting regions of the microcavity device not provided with the light-integrating portion of the light-integrating element.
