  • HIGH PERFORMANCE LIGHT-EMITTING DEVICES
    Publication number: 20110068361
    Abstract: A light emitting device in the form of a layered structure has a passive bottom multilayer stack including a cathode layer, a cavity layer including a light emitting region, a passive top multilayer stack including a hole transport layer, and a transparent anode layer. The passive bottom and top multilayer stacks are devoid of a light emitting layer. A transparent substrate, through which light is emitted from the device, is located over the top multilayer stack. At least one functional additional layer group in the passive top multilayer stack controls the reflectance of the passive top multilayer stack and phase changes occurring upon reflection from the passive top multilayer stack in the cavity layer.

  • High performance light-emitting devices
    Patent number: 7863632
    Abstract: An organic light emitting device consists of a layered structure including a top multilayer stack, a bottom multilayer stack, a cavity layer between the top multilayer stack and the bottom multilayer stack, and an organic light emitting region within the cavity layer. The layered structure is constructed such that the product of phase factors ?1 and ?2 is.
